How to evenly pour the foundation under the fence. How to choose a foundation for a fence - types and criteria
So we decided to put up a fence. The basis of this structure will be the foundation, and the quality of the entire structure will depend on its strength.
The base is necessary so that the fence does not undergo deformation on the ground.
If you have the necessary skills, you can make the foundation for the fence with your own hands.
A solid foundation is necessary so that the fence is not subjected to soil deformation
Types of fences
Before proceeding with the device of the base, it is necessary to decide on fence type:
- easy;
- middle;
- heavy.
After determining the type of foundation, you can begin to start work.
For light type fences
For a light type of fencing - corrugated board, picket fence, chain-link mesh - on solid ground, a less expensive method of column filling is quite suitable.
Along the perimeter of the future fence, pits are dug with a depth of 80 to 120 cm at a distance of 1 to 5 meters, pillars are installed in them, bursting with stones and poured with concrete. When using corrugated board the distance between the posts is recommended no more than 2 meters, taking into account the windage of the material under wind loads.
This video shows how to build a foundation for a fence:
If the soil is loose, sandy or silty, a tape-pillar type of foundation for a do-it-yourself fence is suitable. This type of plinth is best suited for do-it-yourself construction.
Pouring order
We divide all the work into five stages in order to do it without mistakes fence foundation:
- It is necessary to make markings along the perimeter of the foundation: for this, pegs are driven in and the rope is pulled, be sure to fix it at the corners. At the turning points, it is necessary to hammer in a peg, also mark a place for the gate and the gate.
- They dig a trench 35-40 cm wide and up to 50 cm deep, in places where the pillars will be installed, they make recesses up to 90 cm. The recommended distance between the pillars is 2 meters, and the height of the pillar, taking into account the underground part, is at least 2.5 meters. We install the pillars, fix them strictly vertically with stones, broken bricks and gravel, check the level - this is important. The bottom of the trench is covered with a 5 cm pillow of gravel.
Follow the rules for pouring the foundation under the fence in order to end up with a solid structure
- They begin to install a reinforcing belt from corrugated reinforcement 10-15 mm, it is not recommended to use welding at the joints, it is better to use wire, longitudinal reinforcement should be corrugated, with a diameter of at least 12 mm, and transverse and vertical reinforcement can be smooth and smaller diameter. The reinforcing belt is first made and then lowered into the trench, be sure to tie the posts - this will strengthen the structure.
- They put up formwork. To assemble it, you can use improvised materials - old boards, plywood, slate, and so on. This will reduce the cost of construction, the main task of the formwork is to provide the foundation with a flat surface. Expose and wedged the formwork 25-30 cm above the surface, check the possibility of leakage of the filling mixture. Conduct a thorough check of the formwork before starting concrete work. The formwork is a temporary element and should be easily dismantled upon completion of work.
- Pouring concrete. Concrete in stages with horizontal layers and different type solution. A rougher one with gravel or crushed stone is poured into the ground, and soft sand and cement are poured above the ground. With phased pouring, it will be possible to avoid voids in concrete. The formwork is removed after 5 days. In dry weather, the foundation must be watered to prevent cracks. Subsequent work can be started after complete drying, when the base gains strength.
Foundation for the middle type
The average type of fencing implies a mixed structure: powerful pillars made of brick, cinder block, stone or betonite and light material between them - such as a wooden picket fence, corrugated board or a rebar lattice.
Such a fence requires a more reliable base. For these types of fences, as well as for light ones, a strip foundation for a fence is suitable.
A feature of medium structures is the installation of additional supports at the installation sites of the pillars.
To do this, where there will be pillars, they dig holes, given that the depth of the foundation for the fence should be greater than the freezing layer, and 50 × 50 cm wide, we knit a reinforcement frame, insert it into the hole and concrete.
For heavy structures
Heavy fences are structures made of brick, stone or concrete and have a large mass, therefore, if the foundation is not properly constructed, they are often subject to deformation; these fences require a more powerful monolithic tape base.
When constructing this foundation, it is necessary to dig the entire trench with a depth of 30-40 cm more than the freezing depth, in order to achieve maximum reliability, it is necessary to make a more powerful reinforced belt from reinforcement of at least 12 mm, it is thanks to the reinforcement that the load will be distributed evenly throughout the structure.
It must be remembered that the width of the fill must be greater than that of the wall of the structure, by 15-20 cm. Thus, a monolithic strip foundation of special strength will be obtained.
An important step is the pouring of concrete, therefore, before proceeding to this process, you should make sure that everything is ready and check for necessary tool. The foundation is poured with ordinary concrete. For the manufacture of the solution independently, the necessary proportions are 2: 2: 1 (crushed stone: sand: cement).
Such a concrete base for the fence will last for many years without defects and damage.
If you want to protect your site from neighbors, passers-by and to ensure the safety of private property, use fences. But in order for the fence to be reliable and durable, it is necessary to create a strong foundation. This raises the question - how to fill the foundation under the fence and what are the basic rules for performing this operation. The requirements that arise for the base of the fence are the same as for living quarters, resistance to destruction and the ability to support the weight of the structure.
Types of foundation for fences
The most reliable fences are made of iron rods bricks or concrete slabs, due to which the weight becomes quite large. This does not allow the use of shallow or shallow foundations, due to the insecurity of the possibility of collapses.
When choosing the type of foundation, it is worth considering the bearing capacity of the soil and the level of groundwater. At the same time, it is important what buildings or roads are nearby. Without high-quality geological exploration, calculation and drawing up a construction plan, a heavy fence is a danger not only to owners, but also to passers-by.
There are 4 types of foundation for the fence:
- tape;
- stone;
- columnar;
- column-tape (mixed).
Tape evenly distributes the load from the fence to the soil and is used for heavy fences. With a foundation height of 50 cm or more, its ground part is only 10 cm, and the rest is placed in the ground. To create a strip foundation, bricks, monolithic blocks or pouring concrete are used.
![](https://i1.wp.com/kakfundament.ru/wp-content/uploads/2017/09/1-75.jpg)
The stone foundation uses large stones of various sizes and cement. This is a fairly durable way to fence. It is not susceptible to damage, does not require special care.
The columnar foundation is used for light fences due to the fact that the load on the soil is transferred pointwise. It is built of stones, bricks, piles or poured with concrete, easy to prepare and erect.
Column-tape. With this type of foundation, the main load goes to the pillars, and thanks to the tape base poured from above, it is distributed evenly. In this foundation, the strip base is deepened by a maximum of 20 cm. It is built from reinforced concrete or metal piles, which are strengthened from above with cement mortar.
Foundation reinforcement
Any foundation, except for the pile type, can be strengthened by digging special supports into the ground. Such supports can be made of special wood, pipes and other materials that add rigidity to the base. This method is very popular for creating a tape base. The supports after special treatment are buried up to 2 m into the ground, in increments of 2–3 m.
If the fence is planned from corrugated board, then strengthening the foundation is mandatory. Pipes will not only fasten the foundation, but also hold the fence sheets on themselves.
Before applying an anti-corrosion compound to metal amplifiers, it is necessary to clean them of rust or any other contaminants. If metal pipes are used, then they must not only be covered with moisture-resistant compounds on the outside, but also inside. Another option for protecting against moisture contained in binder solutions is the installation of caps at the ends of the pipes.
Preparatory work
To fill the foundation for the fence, it is necessary to purchase materials and tools, as well as to prepare the territory, depending on the chosen foundation. The main thing is to have a construction plan with accurate calculations that will facilitate construction work, and save money on buying and redoing mistakes.
Tools and materials:
- Bulgarian;
- cement M400;
- reinforcement with a diameter of 0.8 mm;
- welding machine or knitting wire for fittings;
- metal poles, with a diameter of 5 cm or more, to strengthen the poles;
- profiled pipes for a fence from a profiled sheet;
- boards or other formwork materials;
- roulette;
- pegs, for marking the territory;
- rope, creates boundaries earthworks, the ends are tied around the pegs;
- level, to check horizontality;
- a concrete mixer, or a construction mixer with a container for creating a solution;
- shovels, if the trench or pit will be created manually.
The construction of the foundation begins with the markup. For this purpose, pegs are installed around the perimeter of the future foundation, four for each wall, and a rope is pulled between them. You should get a rectangle of rope. In order for the rope not to sag, additional pegs are installed. For a columnar foundation, mark the position of the pillars by placing stakes at their corners, and fastening the ropes across the previous one to make a square the size of the future pillar.
For the strip foundation, an indent is made on each side of the border by 30 cm for mounting the formwork. If the foundation is of a mixed type, then the trench between the pits for future pillars is 30-40 cm deep.
If a brick foundation will be used, then at least 2 m of free space must be provided. This is also necessary for a columnar foundation made of bricks.
If the fence is built on a slope, then it must be borne in mind that the bottom of the trench must be stepped, and the base will consist of several sections. The bottom of each fragment must be absolutely flat, and to prevent slipping, the edges of adjacent sections are connected by poles.

Creating a tape type foundation
Crushed stone from 10 cm is laid at the bottom of the trench, after which it must be leveled. 5 cm of sand is poured on top of the gravel, and compacted. After that, you can proceed to the installation of formwork. The best way for concreting under the fence, this is a removable formwork made of boards. They are strong enough and cheap enough for private construction. First you need to mount the boards in the shields, which will be the walls of the formwork, then lower them into the trench and install the jumpers so that the foundation is the same width. Creation of stops in the walls of the trench along the entire length of the formwork.
Before pouring concrete, it is necessary to create reinforcement. The fittings can be welded or tied with wire, this does not particularly affect the result. The finished reinforcement should contain 4 horizontal rods, 2 from the bottom and top, as well as vertical rods, in 20 cm increments. The reinforcement should be 1.5-2 cm smaller than the future foundation so that the concrete completely covers it to prevent contact with moisture . In place of the future gate or gate, a grillage is welded on top of the reinforcement to enhance the bearing capacity.
How to properly fill the strip foundation under the fence, you can see the video
To prevent seepage of "concrete milk" into the ground, a dense film or waterproofing is laid on the bottom of the formwork, depending on the funds allocated for construction. If this is not done, the base may be brittle and prone to cracks. With a small budget and the inability to use insulation, the trench is moistened with water so that the earth does not pull it from the foundation. However, due to the drying time of the concrete mixture, this method is still less reliable.
Foundation pouring
The mixture for the foundation is created in proportions of 4: 2: 1, sand, crushed stone and cement, respectively. For a homogeneous consistency, it is necessary to start mixing with cement and water, after obtaining a homogeneous composition, sand is gradually added, and then crushed stone. If the foundation is not sectional, then it is advisable to pour the mixture within 1 day. Concrete is poured into the formwork by 5–10 cm, after which reinforcement is installed, and pouring continues. It is better to fix the reinforcement at the top until the concrete mixture reaches its top, this will prevent possible distortions that can occur due to the heterogeneity of the concrete during pouring.
![](https://i1.wp.com/kakfundament.ru/wp-content/uploads/2017/09/1-77.jpg)
With a stepped foundation, the same is done only in sections, and the reinforcement on the edge of the bottom protrudes so as to be a continuation of the top reinforcement. After the lower reinforcement hardens, the formwork of the upper section and the connecting column is mounted and the pouring is repeated. Thanks to this design, uniformity of the foundation is achieved, which prevents possible landslides of the fence.
Before proceeding with the construction of the fence, as in the foundation of the house, it is necessary to lay insulating material. The most affordable is roofing material.
The difference between pouring a columnar base and a tape base is only in the final result. In a mixed base, a grillage is welded onto the reinforcement of the pillars, and then the tape part of the base is poured.
When pouring the base, it must be remembered that it must fulfill its functions for at least 10 years. A properly erected base will not require repair for a long time, it will allow you to install a heavy fence and gates that protect privacy from prying eyes.
Any personal plot sooner or later requires fencing. Therefore, this problem is relevant for their owners. In order for the installed fence to serve as a solid structure and stand for a long time, it is required to lay out the foundation.
Features and functions of the foundation
The main bearing part of the fence is called the foundation. The life of the entire fence will depend on the type and quality of its implementation. With a weak foundation device, or its absence, the fence may squint. Also, swelling of the earth can lead to such a problem, which will entail the destruction of the building envelope.
The foundation for the fence performs the main functions:
- affects the stability of the fence;
- makes it possible to equally share the load on the entire structure;
- provides soil retention in the summer cottage during heavy rains and during the period of snow melting.
Foundation types
The most famous option is considered to be a strip foundation for a fence. This is a necessary element in the manufacture of stone fencing. The base in this case makes it possible to make a uniform load. Strip foundation applicable for making pillars in it.
Initially, you need to dig a trench according to the calculated data. On its bottom fall asleep rubble with sand. A formwork with a height of up to 30 cm is built above the pit, and support pillars and metal reinforcement are laid inside. At the end, the foundation is to be poured.
A cheaper option for building foundations - columnar foundation. This type is often used for sandy or clay soils.
Asbestos or metal poles serve as reliable protection. The support can also be brickwork made on the basis of concrete. The gap between the two supports is approximately 1.5-2 m.
Depending on what kind of soil and weather conditions, a trench under the supports is dug to a depth of 1-1.5 m. A sand-gravel cushion is poured into the very bottom of the pit, after which it is compacted. Then they put the pillars in a vertical position, and the trench is poured with concrete.
Often people use a combined foundation that combines the above two types of concrete. Its application is carried out in the construction of concrete-tiled fences, profiled sheet structures.
The price of a foundation for a fence with brick pillars consists of the prices of the stocks used. Based on whose production it is, the cost of one bag will come out. On average, it varies from 200 to 250 rubles.
Manufacturing
Preparing the foundation for the fence yourself is quite simple. It is only necessary to first calculate everything and adhere to all points of the instructions when carrying out actions.
To determine the depth of laying the foundation, it is necessary to take into account the main points:
- design characteristics;
- the depth to which the soil freezes;
- terrain slope;
- the quality of the land layer and the height of the sandy waters.
For the correctness of all calculations, you need to calculate the area of \u200b\u200bthe base from the foundation. For example, if the length of the supporting structure is 50 m and the width is 30 cm, then it is not difficult to calculate the area (15 m2) here. Subsequently, this parameter will be useful for calculating the depth at which the foundation is laid.
At the same time, it is necessary to reveal what its reliable area is. We divide the pressure index of the above-ground part by the value of the bearing base, corrected for the reliability index, by the soil resistance and the coefficient of working conditions.
The final result must be compared with the expected area. The final must be higher than the calculated, otherwise it is subject to adjustment.
fill
How to fill the foundation under the fence correctly? The heaving soil layer requires pouring a combined foundation. Before starting work, it is required to dig a trench, the size of which must correspond to the calculated depth and width. Holes must be drilled in the place where the support poles will be installed.
Then, a wooden formwork is made around the prepared base. At the bottom of each dug hole under the post, you need to lay a roofing material, laid in half. After that, the installation of supports and the reinforcement of the foundation with the help of a reinforcing mesh is done.
Next, the foundation bay begins under the fence in the horizontal direction. When pouring the concrete mixture, it is impossible to allow the formwork to be hidden from one end to the very top, and from the other it is completely absent. Drying time for concrete takes about 3 days.
In hot weather, the foundation should be moistened with water. The formwork is removed from the tape after 2 weeks.
Filling a tape shallowly buried foundation is easier. It is laid above a layer of frozen soil. For this reason, the correct foundation for the fence is resistant to interseasonal ground movements.
The foundation device is performed as follows:
- Make a trench to a depth of 0.5 m.
- Cover the lower part of the trench with sand (0.15 m) and press it down.
- Sprinkle the top with crushed stone (0.15 m).
- Drill holes for digging in pillars, pour sand on the bottom, insert supports and align them.
- Connect the posts to each other with reinforcement using a welding tool.
Install the formwork and pour the concrete mixture. At the end of the pouring work, you need to make sure that the pillars are installed evenly.
For other types of fences
It will be necessary to fill in a columnar foundation for a fence made of corrugated board when the height of the fence is up to 1.2 m. If the parameters of the profiled sheet are exceeded, a strip foundation will be needed.
Since the columnar type of material has a high windage, it is subject to increased load during a hurricane. As a result, the destruction of the support and everything else can occur.
To make a fence holding on brick pillars, you will need to build a sufficiently strong foundation for it. Such fences are prone to damage with uneven shrinkage. In the pillars, a mortgage device is recommended. It is connected with the transverse parts of the entire fence for a strong fixation.
Photo of the foundation for the fence
To build a foundation for a heavy fence seems only at first glance to be a rather easy job. But the durability of the fence itself depends on the correct installation in compliance with all conditions. The requirements that exist regarding the installation of the base for the erected fence are no different from the requirements for residential and outbuildings. Otherwise, such a fence, like any other structure, will not fulfill its direct functions.
That is why, in order to create a strong foundation for a structure, poles, monolithic structures and a strip foundation are required. After all, a good solid fence is inherently a wall consisting of bricks or iron rods, that is, quite heavy building materials. But for privacy, to hide from prying eyes, private developers most often use brick to build a capital fence, which is also much cheaper than iron bars.
The value of the supporting structure
A fence made of brick is considered a heavy structure, which means that in order to withstand such a strong wall, you need a reliable foundation.
An integral part of the cottage, country house or suburban area is a reliable fence. It protects private property from unauthorized access by unauthorized persons, and also prevents the possibility of neighboring animals entering the territory. When planning to build a high-quality and original fence, it is necessary not only to purchase the necessary materials. You should also consider how to build a foundation for a fence. A solid base affects the life of the fence and stability. Consider the features of various variants of the bases.
Choosing the foundation for the fence - important points
When planning to pour the foundation under the fence with your own hands, it is important to choose the best option for the design of the base.
It must meet the following criteria:
- ensure the stability of the massive fence;
- evenly distribute the weight of the fence on the ground;
- to keep the enclosing structure from deformations and distortions;
- prevent collapse under the influence of wind or ground movements.
The strength characteristics of the base are directly proportional to the weight of the building envelope.
The service life of the fence and its main characteristics largely depend on the quality of the foundation.
When thinking about how to make a foundation for a fence, you should choose the best option for the design of the base, after analyzing the following factors:
- type and main characteristics of the soil located at the installation site of the future fence;
- the possible amount of subsidence of the soil with seasonal fluctuations in humidity and temperature;
- the possibility of washing away the base with groundwater, as well as precipitation;
- the mass of the future fence, which can cause subsidence of the base;
- the area and material of the fence, which can be deformed under the influence of wind load;
- the total amount of upcoming costs that it is advisable to calculate before starting construction works;
- features of the terrain that affect the design features of the foundation being built;
- the need for building materials that will need to be purchased and delivered to the place of work in a timely manner.
When performing the analysis, one should also pay attention to the proximity to the fence of busy roads, as well as railways. The design must painlessly perceive the vibration loads that are created during the movement of vehicles.
For the construction of fences, various types of foundations are used:
- tape-columnar. It is made in the form of a concrete strip, which has thickenings at the locations of the columns. Reinforcing bars are laid along the length of the tape, increasing its strength. The tape-column design has positively proven itself in cold climatic conditions with freezing soils. The basis of the combined type is used for wooden and metal fences with brick or block pillars;
- columnar. This is an inexpensive base. Filling the foundation under the fence with your own hands is quite simple. It provides for the concreting of supports in pits prepared in the soil. The concrete mixture after pouring must be rammed. The columnar version of the base is used for wooden fences, as well as structures made of profiled sheet and chain-link mesh. With an increase in the weight of the fence, it is necessary to make poles with an increased depth of immersion in the soil;
![](https://i2.wp.com/pobetony.expert/wp-content/uploads/2018/02/Fundament-pod-zabor-1-640x559.jpeg)
- tape. Due to the increased margin of safety, it is able to take the weight of heavy fences and brick fences. It is carried out by pouring a reinforced concrete tape, deepened into the soil by 60–70 cm. The tape base takes the weight of the fence evenly along the entire length. It can be arranged independently. To do this, it is necessary to dig a pit, fill it with gravel, lay reinforcing cage, assemble panel formwork and make concreting;
- gravel. Gravel bed base is a type of strip structures. It is used for the installation of massive fences with an increased height of the enclosing part. The algorithm for the formation of a gravel base provides for the preparation of a trench, and then the creation of a gravel-sand cushion. Further, the array is compacted, layer-by-layer pouring with concrete mortar and installation of supporting pillars in liquid concrete;
- stone. This type of foundation has a centuries-old history, because stone has traditionally been used to build foundations. The algorithm for the production of construction works is similar to the construction of a strip base. The difference is that instead of pouring concrete, stones are laid on a crushed stone base. In this case, the reinforcement is not installed, and the stones are combined into a single array with a hardened cement mortar.
Depending on the design features of the fences, apply different types foundation foundations. One of the most common options is the tape-column. Thanks to design features, it is able to perceive the significant loads that most of the erected fences create. Let us dwell on the features and technology of the construction of each type of foundation.
![](https://i0.wp.com/pobetony.expert/wp-content/uploads/2018/02/Fundament-pod-zabor-2-640x480.jpg)
Ribbon-column foundation of the fence
Main features:
- the design is combined, made in the form of a concrete tape, reinforced in the places where the supports are installed;
- increased margin of safety due to steel reinforcement along the entire length of the concrete belt;
- uniform distribution of the load from the fence along the entire length of the supporting structure;
- the possibility of self-construction due to the simplicity of the foundation.
It is necessary to note the reduced construction cycle, with a total duration of no more than ten days. At the preparatory stage of work, it is important to perform the following work:
- assess the condition of the soil, the shifts of which can reduce the strength of the foundation;
- calculate the dimensions of the concrete base corresponding to the weight of the fence;
- determine the dimensions of the reinforcing cage that prevents the formation of cracks;
- purchase materials necessary for construction work;
- prepare working tools and equipment.
The foundation for the fence is poured according to the following algorithm:
- Mark the outline future basis using pegs and a cord stretched between them.
- Prepare a pit with a depth of 60-70 cm and a width corresponding to the dimensions of the future concrete base.
![](https://i2.wp.com/pobetony.expert/wp-content/uploads/2018/02/Fundament-pod-zabor-3-640x480.jpg)
- Make local recesses in the pit at the locations of the supporting columns, deepening below the bottom of the trench by 20 cm.
- Carefully level the bottom of the trench with a shovel, eliminate large irregularities on the side walls.
- Pour a mixture of sand and gravel into the trench, compact it to a cushion thickness of 15 cm.
- Install a formwork structure along the contour of the base, which will prevent the collapse of the soil.
- Coat the wood surface inside the formwork with waterproofing to keep moisture in the concrete.
- Drive in support posts from metal pipes, ensuring their vertical position.
- Lay the reinforcing cage elements inside the panel structure, connect them with knitting wire.
- Prepare the concrete mixture and pour it, evenly distributing it along the entire length of the formwork.
- Compact the poured concrete to release air pockets using steel bars or a vibrator.
- Level the top plane of the poured concrete mass using a trowel or rule.
- Maintain the moisture concentration necessary for cement hydration by periodically complicating the surface.
- Lay sheets of roofing material or polyethylene on the concrete tape to maintain constant humidity.
- Do not subject the hardening concrete mass to loads until it reaches its operational strength.
- After three weeks, dismantle the wooden formwork, remove its components from the pit.
The tape-column base will be used for a long time, maintaining integrity under the influence of significant loads.

Fence with a columnar foundation
This design has its own characteristics:
- does not require special training;
- can be equipped on their own;
- will save financial resources.
For the construction, it is necessary to prepare the required number of pits, install vertically columnar supports in them and then pour the concrete mixture. Wooden boards can then be nailed to the posts, wire mesh can be fixed, or corrugated board can be fixed.
Consider in detail the mechanism of construction:
- Prepare a pit with a garden drill.
- Fill them with a pillow of a mixture of sand and gravel.
- Thoroughly tamp the bedding.
- Lower the posts into the pits at a general level.
- Fill in the space between the supports and the ground concrete mix.
When performing work, pay attention to the following points:
- the interval between the supports, which should correspond to 2–2.5 m;
- the depth of the pits, which should be 1–1.2 m;
- the diameter of the recesses exceeding the size of the pillars by 15–20 cm;
- the thickness of the backfill, which should not exceed 10–15 cm.
When performing work, one should be guided by the mass of the future fence and the features of the soil.

Tape pouring the foundation for the fence
Tape base feature:
- increased strength;
- resistance to soil movements;
- even distribution of loads.
The following materials are used for manufacturing:
- concrete M200 and above, intended for pouring;
- reinforcement with a cross section of 0.8–10 mm, used for the manufacture of the frame;
- wooden panels, moisture-resistant plywood or boards for formwork assembly.
The construction process is similar to the arrangement of a strip-column base. Procedure:
- Dig a hole 70–80 cm deep.
- Pour a layer of gravel-sand mixture on the bottom.
- Tamp it down to 15 cm thick.
- Install the shield formwork, fix it.
- Assemble the reinforcing mesh and lay it in the formwork.
- Pour concrete into the trench.
A month after concreting, the cement hydration processes will be completed and further work can be carried out.

Concrete foundation for gravel fence
The main features of the foundation on gravel bedding:
- increased load capacity;
- acceptable level of costs;
- simple design.
The sequence of technological operations resembles the execution of work on the formation of other types of bases:
- Prepare a trench around the perimeter of the fence.
- Fill its bottom with a layer of gravel mixed with sand.
- Compact the pillow, providing a layer thickness of 10-15 cm.
- Tie the reinforcement cage and place it in the trench.
- Install, if necessary, embedded elements.
- Fill the pit with concrete mix, level it.
If it is necessary to install support columns, they can be placed in the trench before the concrete is poured.
Fence stone foundation
Peculiarities:
- increased strength;
![](https://i0.wp.com/pobetony.expert/wp-content/uploads/2018/02/Fundament-pod-zabor-7-640x480.jpg)
- the possibility of using natural material;
- attractive appearance;
- long service life;
- high level of reliability;
- lack of reinforcing bars;
- harmonious combination with forged elements.
Construction procedure:
- Remove the soil along the length of the fence, forming a trench.
- Pour crushed stone on the bottom and carefully compact it.
- Lay large stones, filling the cracks with small stones.
- Make a laying, connecting the elements with a cement mortar.
- Carry out work to the required height of the stone base.
For normal aesthetic perception, laying can be stopped when the foundation is raised above the zero mark by 50 cm.
Summing up
Various types of foundations can be used to build a fence. The choice of the optimal option is made individually, depending on the characteristics of the soil, the results of calculations and personal preferences. When performing work, one should be guided by the requirements of technology and use high-quality materials. In the absence of skills in performing construction work, it is worth contacting professional builders. They will make the necessary calculations and quickly build a solid foundation for future fencing.
