Monolithic site. Landfall Monolith
Of the many options for creating stairs, monolithic ones are one of the most reliable and durable. Therefore, often there is a need to make a monolithic staircase with your own hands. This process is time-consuming, but if you carefully understand everything, then it’s quite possible to build a monolithic staircase, even for a layman.
Monolithic or concrete staircases are distinguished by their safe design and stability. They are strong, durable and fireproof. Affordable price allows you to install such a staircase, and an individual way of decoration will harmoniously fit into the interior of the room. Monolithic stairs, the photos of which are presented below, will clearly demonstrate the installation process.
The most suitable material for the construction of stairs is concrete. Due to this, they are very durable and withstand heavy loads.
Monolithic stairs are:
- with direct marches: single-march, two-march,
- l-shaped stairs
- spiral staircases,
- u-shaped stairs
- combined.
Most public or industrial buildings use monolithic stairs with straight marches. Curved stairs are chosen by those who want to decorate or diversify the interior.
Tools for working on the filling monolithic staircase
In the manufacture of monolithic stairs, it is very important to calculate and design each step. To carry out the work, you need such devices:
- concrete mixer,
- hammer drill
- bulgarian,
- right angle square,
- kapron threads
- water or laser level,
- rule of two meters,
- plywood, boards,
- fittings,
- sand, water, concrete,
- grinding machine.
Calculation and design of monolithic concrete stairs
The calculation of the material is carried out according to the number of steps and the width of the landing. The easiest way to build a staircase, which is located between two walls. In this case, the marking is applied directly to the walls, and the formwork does not need to be built. It is more difficult if the staircase is adjacent to one wall. Then on the second side you need to make the formwork, and on the side of the wall - marking.
It is difficult to place a single-flight staircase in the house, since its installation requires a large area, and does not always harmoniously fit into the layout of the room. Then two-flight monolithic stairs with a landing are installed. It will be about installing such a ladder.
To make the correct layout under the stairs, monolithic reinforced concrete with a landing, use these tips:
- One march of such a staircase consists of a minimum of three, and a maximum of sixteen steps. If there are more, it will be physically difficult to climb the stairs.
- The staircase must be at least 1.5 sq.m.
- The width of the staircase itself is the width between the handrails, or between the handrail and the wall. When calculating the width of the stairs, it is important to consider its “throughput” - the number of people who can climb it at the same time. The minimum width of the stairs is 90 cm. The most acceptable march width for residential buildings is 1-1.3 m.
- To calculate how many steps will be in the planned staircase, you need to divide the height of the ceilings of two floors by the height of the steps. The optimal height of the steps is 13-16 cm. For example, if the ceiling height is 3.5 m, and the height of the steps is 16 cm, then for such a staircase you need 22 steps. In each opening, 11 pieces.
- The most convenient step depth is 28-32 cm. If we choose a width of 30 cm, then the length of the flight of stairs will be 3.30 m - 30 cm * 11 steps.
- There is 10 cm left on the staircase. Thus, the ceiling height is 3.4 m. This height is divided into two marches. At a height of 1.7 m we make markings and measure the angle of inclination, while measuring 3.3 m - the length of the flight of stairs.
Here are the drawings of a monolithic staircase:
Installation of formwork and frame of reinforcement
- For the construction of formwork, first of all, the base is set. This is what concrete will hold onto after pouring.
- For a support or rack, use a bar 100x100 mm. When choosing a beam, consider the weight of the concrete. The stronger the beam, the better.
- Begin the installation of formwork with the construction of the landing.
- Roofing material, a lining made of plastic film will protect the tree from moisture.
- When the landing is exposed, install the formwork under the marches.
- A very important point is the knitting of the staircase frame from the reinforcement. Reinforcing frame protects concrete and increases the reliability of the stairs. Use fittings with a diameter of 12 mm.
- All horizontal parts of the frame are mounted on the wall.
- Using a wire, with a special hook, we fasten the fittings together. We form cells of 20x15 cm.
- Plywood, edged or semi-edged board is suitable for the formation of steps and formwork.
- After setting the formwork, we make the flanging of the stairs. It serves as a limiter when pouring concrete, and at the same time our future steps are attached to it. The formwork forms the final look of the stairs.
- Use reinforced metal corners to form steps. They will fix the entire wooden formwork structure.
- It is very important to securely fix the bottom step of the stairs. After that, conduct a visual inspection of the resulting formwork.
- To remove differences, all joints of plywood sheets are coated with putty or ground with a planer.
Monolithic staircase
1. After the reinforcing cage is formed and the formwork is ready, we proceed to backfilling the stairs. Options for filling the stairs:
- clay slag
- gravel
- coarse sand
- expanded clay or construction waste.
2. The filled foundation must be carefully leveled and tamped. Tamp in layers, previously slightly moistened with water.
3. After backfill, install waterproofing so that the concrete does not mix with the backfill and does not lose its qualities.
4. Now we begin to fill the monolithic staircase.
First, fill in and form the first two, three steps. During concrete laying, it is advisable to pierce it with any metal devices in order to remove the formed air cavities, which will violate the solidity of the structure.
5. In the process of laying concrete, it is further vibrated. To remove all the cavities formed from the monolithic mass, concrete is squeezed out through the formwork, and is leveled on the surface using a trowel. And thus we form the future view of the steps. The squeezed concrete is thrown up.
6. The same sequence: pouring, laying, vibrating and re-laying we apply for the next steps and for the staircase.
7. Remove the formwork in several stages. A few days after pouring concrete, when it has hardened enough, the formwork of the steps is removed. The surface is ground using a grinding disc or angle grinder.
8. About two weeks after pouring concrete, the staircase formwork is removed. Next, proceed to the finish.
Monolithic staircase finishing options
There are many ways to finish monolithic stairs.
Options for facing a monolithic staircase:
- natural or artificial stone
- carpet
- mosaic,
- colored glass,
- plastic,
- clinker or tile
- wood.
Stair railings are forged, wooden, plastic, metal and even glass.
Wood paneling has many advantages. Marches on concrete stairs are very rigid and are an excellent base for wood. Even if the steps are not very smooth, the tree will hide all these shortcomings. Monolithic wooden stairs are:
- with oak finish,
- with solid ash
- beech decking,
- decoration with various types of wood.
For finishing a monolithic staircase, the best option is oak. Its only drawback is its high cost. To save money, the option of finishing the stairs from larch is suitable, it is practically not inferior to oak in hardness. The most budgetary option is pine or spruce, they are very quickly erased on the steps.
It is best to lay wooden steps on moisture-proof plywood.
If there are small children or elderly people at home, then the option of finishing the monolithic staircase with carpet is suitable. As well as in hotels and restaurants, such stairs are finished with carpet. It is very easy to fit and fasten with wooden or plastic skirting boards. To extend the life of your carpet, lay a felt or similar material under it.
Also, tiles: ceramic, ceramic or brick, suitable for finishing a monolithic staircase. Here you need to choose based on your preferences, design and cost.
Tip: to finish the monolithic staircase with tiles, the surface should be perfectly flat. When choosing a tile, make sure that it has an anti-slip coating.
When decorating a monolithic staircase with natural or artificial stones, you need to consider both the pros and cons. Despite the fact that this finish will last a long time and looks very presentable, it has a high cost and a sonorous sound effect. And also it is difficult to look after porous rocks of stones.
For SATORI, monolithic work is one of the most important areas of work. Monolithic construction of residential buildings and structures has been actively implemented by our specialists for over 15 years. In monolithic works, we use modern equipment and the latest technology, and all employees have the necessary level of qualification.
Why is it better to trust the execution of monolithic work to professionals?
Monolithic work is quite complex and time-consuming. They are carried out in several stages, require special equipment and a high level of staff training. Therefore, the construction of monolithic houses, buildings and structures should be done only by professionals. SATORI specialists have vast experience and the necessary knowledge to perform the entire range of monolithic works and offer adequate prices for their services.

The volume of monolithic work amounted to more than 50 thousand m 3. Cooperation with SATORI guarantees you quality at affordable prices, promptness and the acquisition of a reliable, permanent partner.
Monolithic products
Design features of monolithic products provide for their mandatory reinforcement. Monolithic structures reinforced with a steel frame are called reinforced concrete structures.
Reinforcement of products performs the function of a “rod” on which the entire monolithic structure rests. The reinforcing structure (hereinafter the reinforcing cage or simply reinforcement) depends on the purpose and the loads that the monolithic product will bear.
As reinforcement of reinforced concrete structures, individual rods and wires, wire bundles and packages, welded wire mesh, flat and volumetric frames are used.
A special group of reinforcing products is embedded parts. If the reinforcing cage in the finished product is walled up in concrete, then the embedded parts go to the concrete surface and serve as a connecting link between the frame and the products, which, if necessary, will be attached to this reinforced concrete structure.
In general terms, you now imagine what monolithic reinforced concrete structures are. What is a reinforcing cage, specifically for the landing, we will consider below.
Reinforcement work
Reinforcing work should be carried out in accordance with the requirements and recommendations of SNiP 3.03.01-87 “Bearing and enclosing structures”, GOST 19292-73, “Instructions for welding reinforcement joints and embedded parts of reinforced concrete structures” SN 393-78, “Reinforcing Steel Production Guides works "TsNIIOMTP Gosstroy-1977. And other applicable regulatory documents.
The manufacture of the reinforcing cage and mesh should be performed according to the drawings and have the exact location of the elements to be welded. Replacement of the reinforcing steel provided for by the project in class, grade and assortment is agreed with the design organization.
The manufacturing process of the reinforcing cage provides:
dressing and cutting of steel reinforcement, wire, supplied in coils with a diameter of 3 ... 14 mm and in rods with a diameter of 12 ... 40 mm to rods of measured length;
dressing (bending) and butt welding of rods to the desired size;
welding grids and frames;
enlarged assembly (welding and wire knitting) of volume reinforcing blocks;
transportation and installation of frames at a construction site.
The reinforcing cage of the monolithic section No. 3 for the landing is performed according to the dimensions indicated on the diagrams (see. Fig.).
Note:
Steel of class A-III, diameter 12-20 mm - steel of a periodic profile (in rods).
Steel class A-III dia 8 mm - smooth reinforcement (in coils).
Table 1: Reinforcement specification for the monolithic section of the landing
Brand position | Designation | Name | Weight in kg | Consumption in linear meters | Note |
5 | GOST 5781-82 | Armature dia. 8 A-III | 35 | 106 | on one platform |
6 | GOST 5781-82 | Armature dia. 12 A-III | 5 | 7 | also |
7 | GOST 5781-82 | Armature diam. 20 A-II | 14 | 7 | also |
Concrete class At 15 | 0.5 m3 |
The mesh must be welded by spot welding. For the frame, reinforcement is used according to the specified table:
Cross intersections of rebars of the rebars mounted individually, at the points of intersection established in the project, should be fastened with knitting wire. In the reinforcing cage should not be dangling, intersecting and broken wires. The wire should fit snugly together.
Corrosion-affected wire (or reinforcing wire in coils) is not allowed for use. A wire is considered corroded if rust cannot be removed by wiping.
Attention! To avoid personal injury and fire safety -
Only persons at least 18 years of age who have undergone special training (welder-builder) and have permission to perform welding work are allowed to perform welding work.
Concrete works
Before performing concrete work, it is necessary to install scaffolding and formwork for them under a monolith. For the principle of formwork installation, see the section “Design and Disassembly of the Formwork for a Monolithic Slab”.
Concrete work should be performed in accordance with the requirements and recommendations of SNiP 3.03.01-87 “Bearing and enclosing structures”. The composition of the concrete mix, preparation, acceptance rules, control methods and transportation must comply with GOST 7473-85.
The fittings and formwork must be cleaned of debris, dirt and exfoliating rust before concreting. The surface of the wooden formwork adjacent to the concrete must be moistened. Close the gaps formed during the installation of the frame in the formwork flooring.
Before installing the frame on the formwork, linings (crackers made of cement mortar) must be fixed, providing the necessary clearance between the reinforcement and the formwork to form a protective layer of overlap.
Attention! Mounted fittings must be secured against displacement and protected from damage that may occur during the concreting of the slab structure. It is forbidden to use linings from scraps of reinforcement, wooden blocks and crushed stone.
The concrete mix should be laid in the structure with horizontal layers of the same thickness without breaks, with a consistent laying direction in one direction in all layers. When laying a concrete mixture, methods should be applied that exclude its delamination.
The concrete mixture is compacted by a vibrator, which during operation cannot be supported by reinforcement. Vibration can only be stopped after the appearance of cement milk on the surface.
In places where the thickness of the reinforcement or the location of the formwork prevents the concrete mixture from vibrating, the mixture is bayoneted (sealed with a metal rod, “bayonet”).
Note: Concrete mixture may be compacted with a surface vibrator if the thickness of the concrete mixture in structures with double reinforcement does not exceed 120 mm.
Ceilings, seamlessly connected with vertical structures (walls, columns), are concreted 1-2 hours after concreting these structures. Working seams must be arranged in the middle third of the spans of the plate.
Attention! During breaks in the laying of concrete in the places of the alleged cliff, vertical shields should be temporarily installed. Concreting should be brought to these shields.
After a break, the concrete mixture is laid on the surface of the working joint, previously cleaned of dirt (cement film) and washed with water, provided that the strength of the previously laid concrete is at least 15 kgf / cm2.
The upper level of the mixture to be laid should be 50mm below the top of the formwork panels.
Concrete work is carried out only at a positive ambient temperature.
Attention! It is not allowed to restore the mobility of the concrete mixture to the required consistency by adding water at the place of its laying.
If cracks appear on the surface of the concrete after it has been laid due to plastic shrinkage, it is allowed no later than 1 hour after the completion of the concrete laying, its repeated surface vibration.
Concrete aging and maintenance
When keeping laid concrete in the initial period of its hardening, it is necessary:
maintain temperature and humidity conditions, providing an increase in the strength of concrete;
protect hardening concrete from impacts, shocks and other mechanical influences;
protect hardening concrete from the effects of wind, direct sunlight and systematically moisturize.
Note: During initial care, direct contact of hardening concrete with water is not allowed (i.e. cover concrete from moisture in the event of rain).
Moistening should be carried out by hardening the concrete by spraying with a frequency at which the surface of the concrete would remain wet during the maintenance period.
Concrete surfaces not further intended for monolithic connection with concrete or mortar should be covered with film-forming compounds or protective films instead of shelter and watering.
The exposed surface of the structure should be covered with a solid cloth over the entire area, the edges of the cloth should fit snugly against the side surfaces of the concrete.
To exclude the time-consuming operation of wet-cleaning concrete and accelerating its hardening, concrete is electrically heated.
Concrete care is discontinued in the evening. After cessation of care, the concrete surfaces must be kept under the coating for another 2-3 days without additional wetting.
Attention!The movement of people on concrete structures, as well as the installation of scaffolding and formwork on them, is allowed only after concrete reaches a strength of at least 15 kgf / cm2.
The dismantling of monolithic structures should be carried out in the following times:
removal of the side formwork elements that do not bear the load from the weight of the structures (for a loggia, except for the landing and sloping slabs) - after reaching concrete strength, ensuring the safety of the surface and the edges of the corners when removing the formwork;
dismantling of supporting reinforced concrete structures (staircase and sloping slab) - after concrete reaches strength and depends on the size of the monolithic structure.
One of the most important stages in the construction of buildings, without which the construction process is almost impossible, are concrete works. It is concrete, used both in the foundation and in walls or other parts of buildings, due to its extremely durable characteristics, that plays the role of the main support of the entire building.
This process takes a considerable amount of time, while requiring the expenditure of a large amount of resources, including the labor of workers. Take lightly of concrete work - This means jeopardizing the successful completion of the entire construction. For this reason, choosing a company that will carry out such work is a task no less responsible than the work itself. It is no secret that not every company that provides construction services has professional specialists who are able to work with concrete efficiently. This is the reason to seek help from the Russian Professional Construction Company, since we have extensive experience in such work, and the use of only high-quality materials and highly qualified professionals make it possible to guarantee that the building will turn out to be reliable and durable.
Assurances that arrangement of floors, foundations, concrete walkways and the like, they do not require any special knowledge, have not the slightest foundation, since this requires taking into account the specifics of many factors that inevitably arise during construction. Therefore, even such a simple, at first glance, process as blind area device, should be done only by competent specialists.
Specialists who work in our company have extensive experience in carrying out this type of work. In addition, they have all the necessary tools and modern equipment, which is a guarantee of high quality concrete work, any level of difficulty. We are able to guarantee the construction of truly capital buildings with a high degree of reliability, not to mention the excellent operational characteristics. In turn concrete work ratesindicated on our website will allow you to make the most optimal choice when ordering appropriate services.

Duration of foundation construction:
Depending on the complexity, it is built from several weeks to several months. It is better to start the foundation in late April, early May, when the soil warms up. It is necessary to finish it before the onset of the first frosts. Further, experts recommend giving the foundation time to stand before the next spring, so that it can fully gain strength and go through all temperature conditions during seasonal weather changes. If in the spring there are no defects, then you can confidently continue building the house. If defects are found, then you need to find out the cause of their occurrence. (Is this type of foundation suitable for this soil? Is manufacturing technology violated? And so on.) Usually, as a result of finding out the cause of a defect, its maintainability is determined. While there is no house on the foundation, there are many opportunities for its repair. In the worst case, it is possible to dismantle this foundation and build a new one. And if the house is already standing, this greatly reduces the choice of technical capabilities for repairing the foundation and increases the cost of these works. And the option of building a new foundation, in this case, turns into the construction of a new house and it is very expensive. Therefore, experts recommend not to rush and allocate one year for the construction of the foundation.
The device of concrete paths and platforms with a texture of exposed aggregate.
Placing a large aggregate in the surface layer of concrete - gravel or small stones - gives a beautiful and practical finish. Spread the moistened aggregate evenly over the freshly laid mixture and press it tightly with a wooden block so that its grains are flush with the surface. Place a board across the formwork and level the surface with all your weight. When all the water has evaporated from the surface, with a watering can and brush, wash off a thin layer of concrete so that the grains begin to protrude slightly above the surface. Cover the concrete for 24 hours, and then wash the surface lightly again to remove any residue or sediment from the grains. Cover the concrete again and let it harden.
The steadily growing number of cars per citizen of Russia, as well as the number of personal plots and cottages makes their happy owners think about the need to build parking for a car within their allotment. To ensure this, it is important to complete the sequence of actions that will be discussed later.
The device of a concrete place for a car begins with the preparation of the foundation, which can be done with your own hands and is as follows:
1. Choose a location near the driveway to ensure water flow and unhindered maneuvers.
2. Designate the dimensions, the platform for the car should have standard sizes:
- for cars - 3x6 m;
- for trucks - 4x11 m.
If a site with a large size can be placed on the site, it is recommended to do this, thus, it will be possible to park a truck or two passenger cars.
3. Remove the fertile soil layer to clay in a limited area.
4. Arrange a pillow consisting of the following layers:
- sand, obtained by two or three times adding, moistening and compaction - the thickness should be at least 100 mm;
- gravel, made by adding and tamping, with a thickness of more than 50 mm.
At this preparatory stage of construction is considered completed, the place can already be used to park the car.
Technology Description
After the base of the parking lot is leveled and prepared, you can be sure that there will be no excessive consumption of concrete to compensate for the pits, and that the hillocks will not tear the site under alternating temperature influences. Further operations for the construction of the site include a set of measures immediately preceding the pouring of concrete.
In order to limit the area for pouring, formwork is made of edged boards, the width of which is 20-30 cm.In order to avoid the walls of the mold for filling to fall, it is necessary to fix them in a vertical position by means of metal pegs that are driven into the ground on both sides. The length of the pin should be 40-50 cm, driving to the top edge of the board in increments of 50 cm in a two-way arrangement. At the corners of the wall, the formwork must be fastened together to prevent the flow of mortar.
Due to the fact that the width of the standard rule is 1-1.5 m, and the space for a car is 3-4 m, it is necessary to provide intermediate guides, which can serve as U-shaped ceiling profiles for GVL. Alignment of embedded parts is carried out in the transverse direction, and in the longitudinal it is required to provide a 3-5C slope in the direction of passage for liquid to drain from the surface. To fix the profile, you will have to mix a small volume of concrete and use it as a lining to raise the guides to the desired height, which is 10-15 cm. After the supports of the embedded parts have dried, it will be possible to proceed to filling the area under the car.
While the material of the original foundations under the guides becomes hard, there is time to reinforce the future concrete site. To do this, you will have to buy or build a do-it-yourself wire mesh with a thickness of 5-8 mm with a cell of 100x100 mm. Considering that the middle layer of concrete is subject to reinforcement, it is necessary either to raise the network above the base level by 25-35 mm, or to perform a two-level reinforcing structure. Such a product consists of two layers of mesh, interconnected by jumpers 80 mm long, at a distance from each other of 40-50 mm (assuming a concrete thickness of 100 mm, if the layer is thicker, appropriate adjustment should be made). It is recommended that all the connections of the rods when forming the skeleton be made using a thin wire or PVC clamps.
As soon as the reinforcing nets are connected, they are laid on the base and fastened together to form a single field. After completing all the procedures, you can concrete the platform for the car.
Concrete pouring
Concreting is recommended to be carried out at a time, that is, within one daylight hours, since after a day from the moment of pouring, the solution dries enough to stop hardening with new layers. Pouring preparation can be carried out independently with improvised means (a shovel and a galvanized bath) or using a concrete mixer, which can significantly facilitate the process of any construction.
Concreting is performed above the level of the guides, starting from the end of the site farthest from the road towards the entrance to it. The mortar is laid out over the entire width and is leveled using the rule for embedded parts until the entire volume between the walls of the formwork is filled. After finishing work, it is necessary to cover the place with a layer of plastic film for uniform drying and for protection from rain and moisture.
After the concrete has dried completely, which takes five to ten days, the parking lot, equipped according to all the rules, able to serve for a long time and fruitfully, is ready. Now it remains only to disassemble the temporary formwork and remove the pins used as supporting elements from the ground. In this case, the rods clogged inside the wooden walling and fixed in the concrete layer can be left for subsequent use. In order to avoid bulging of reinforcing sections from the soil as a result of off-season temperature fluctuations, it is required to cut them to the thickness of the concreted area, and remove the parts remaining in the ground.
So that the edges of the site do not break during use, they must be strengthened with a metal corner, one of the shelves of which corresponds to the thickness of the reinforced concrete layer minus 20 mm per weld, and the second can be equal or have less value. The made overlays of profiled rolled metal are fastened by welding between themselves and to the filled bars, allowing to obtain a rigid perimeter.
Turnkey work
If the process of building a parking lot with your own hands is unattractive, you can order the laying of cement mortar and related work in the organization that carries out this type of activity.
The estimate for the device platform for the car will include all of the above operations, the cost of which at the moment is on average, (rubles / cubic meter):
1. Pouring cement mortar and its installation (formwork, reinforcement, concrete work):
- through a mixer - 640-800;
- manually - 800-1000.
2. Knitting reinforcing cages - 2000-3500.
3. Construction of monolithic sites for various purposes (ramps for entry, walkways, blind areas), pouring thickness up to 20 cm - 2500-3000.

An approximate calculation of the cost of concreting a site for a car with dimensions of 3000x6000 mm and a base thickness of 100 mm at the prices above will allow us to get the total cost of turnkey work at the level of 14000 - 16000 rubles.
An increase in the size of the site for the truck to be parked up to 4000x12000 mm, accompanied by a thickening of the base plate to 150 mm, will increase the cost of construction to 32,000 - 35,000 rubles.
