How to pour concrete floor in the garage?

Concrete remains a popular view of the flooring of the garage, due to the relative simplicity of laying and low cost. Of course, you can stay on a simple earth coating, but it will not protect against adverse weather events, does not preserve heat inside the garage, does not have durability. In this case, there is no waterproofing. For high-quality coverage, which will last for many years, it is necessary to perform all the stages of the fill of concrete from the preparation of the soil to the finish color.


Concrete coating in the garage can be further covered with paint, separated by wood or tiles or leave in original form. Concrete can be poured on their own hands without resorting to the help of specialists from.

This material is fully suitable for the floor, among the necessary criteria, which it corresponds is particularly relevant:

  • wear resistance;
  • moisture resistance;
  • strength;
  • resistance to chemical substances;
  • refractory;
  • durability.

The coating in the garage is constantly exposed to strong loads and mechanical effects, so the criterion for wear resistance is particularly important. The surface should not be deformed or crack, even if it is subjected to essential weight loads or temperature difference. When washing a car, it is necessary to be sure that the surface will not deteriorate from moisture exposure.

The surface of the floor periodically needs a wet cleaning, so the indicator of resistance to moisture is important. Since in the garage it is easy to accidentally shed oil or gasoline, the base should not react to chemicals.

Before the fill of the concrete floor, it is advisable to pay attention to the following moments:

  • groundwater level;
  • presence of slope;
  • Garage Help Features from Rain Or Snow.

To simplify the process of filling the floor and achieve the uniformity of the load over the entire surface, it is necessary to fully cover the surface of the floor with concrete 1 time. So the durable monolithic plate is formed.

Pouring can be performed 1 person, however, for monolithic and better results, it is preferable to do it together or even three. The thickness of all layers directly depends on the weight of the car, the amount and weight of items that will be stored in the garage.

Advantages and disadvantages

If we conclude a garage floor, he will have such advantages:

  • resistance to weather conditions, including temperature difference;
  • resistance to moisture;
  • long service life;
  • Simplicity of care.

High concrete thickness causes good strength and durability. Such a design is universal: By and large, you can do without staining, although if you wish, you can perform different surface finish. You can also achieve the smoothness of the concrete floor and polish it until shine. At the cost of the concrete floor is quite affordable.

Compared to other types of coating, the fill of concrete floor needs special skills and use of special tools. Therefore, this process can be called laborious.

Pouring should not be carried out in winter: at low temperatures, the concrete will freeze, and will not freeze.

Such a coating will not hold on long. Since concrete has a property of accumulating various substances (oils, gasoline), there is a highlight of unpleasant odors that are not easy to remove. Dust accumulates on its surface, to remove which is more difficult than from other floor coatings.

Calculation of necessary materials

To calculate the required volume of concrete, you need to multiply the surface area of ​​the garage to the height of concrete fill. So that the concrete coating last long, its height should be at least 10 cm. When calculating the number of necessary concrete, it is worth considering the need to create a material stock of about 10-12%. To increase the qualitative characteristics of concrete, special additives are acquired for the mixture, which increase the resistance to harmful substances and enhance the wear resistance of the coating. For example, for concrete brands from M300 to M550, you can purchase an additive “Elastobeton”, which increases adhesion.


The following tools will be needed for mounting:

  • shovel;
  • concrete mixer;
  • reinforcing material;
  • Lighthouses to determine the flatness of the floor;
  • The rule that is distributed to the spilled concrete on the surface;
  • Vibration machine or needle roller (to remove air bubbles).

Concrete coating is a bit more complicated in comparison with other types of coatings (for example, with rubber).


Before the fill of concrete, it is necessary to prepare soil quality. This process is especially necessary if the garage is located under a slope (it is necessary to obtain a smooth and solid monolithic plate). Preparation lies in alignment and strengthening the surface.

It consists of such stages:

  • Removing the fertile soil and the tamper of the remaining;
  • laying a layer of rubble;
  • laying sand layer;
  • Waterproofing surface.

You can use gravel instead of rubble, but the crushed stone is better because it does not have rounded edges (it provides a good rambling).

First you need to clean the surface from the garbage and remove the soil layer. It takes into account the required distance from the base of the soil to the final result. If there is a lot of loose soil, it must be removed completely, and instead, it is larger than rubble. The rubble layer should be at least 15 cm (it is allowed to 80 cm, the optimal option is 30-45 cm).

On the layer of rubble lay a layer of sand with a thickness of approximately 2-5 cm (optimally 10 cm). It is necessary to make a layer and moderately pour water. To continue the work, it is necessary to wait for the basis of the base (about 1-2 days). Sand is suitable without clay. Before use, sometimes they advise him to sift it.

It is necessary to ensure that the layers are stacked exactly. Permissible deviations are up to 2 cm.

For waterproofing, a polyethylene film is used, which stacked the brass and finds on the walls along the edges. Instead of polyethylene film, rubberoids, membranes and other sealing agents are used. You can use the usual clay. In this case, it is necessary to apply clay in a liquid state on the purified soil, and after it dries, start laying the layers of rubble and sand.

Subtleties of fill

After preparatory activities, you can proceed directly to the pouring of concrete. It is important to correctly fulfill this procedure: the quality of the coating and the appearance of the floor depends on. The process consists of reinforcement with a metal grid (it allows to strengthen the concrete base) and the fill itself. If the garage is heated by the room, after reinforcing it is necessary to carry out thermal insulation. The heat insulation of concrete floor is performed using clay, infernoxis and other materials.

Pluses of clay:

  • resistance to temperature difference;
  • low cost;
  • Simplicity of self-use.

The minuses of the ceramis are:

  • fragility;
  • absorption of moisture;
  • The need for a thick layer for good heat conservation.

The disadvantages of fasteners are the increased value and destruction of the material under the influence of chemicals.

At the same time he has and dignity:

  • high density;
  • Resistance to moisture;
  • Easy use;
  • Lack of toxicity.

For reinforcement, it is necessary to use a steel reinforcement grid, the size of the cells of which is at least 10×10 cm. To connect the parts of the grid use steel wire. Such a grid should act as the holding element, it will not allow the surface to collapse or crack. Fiberglass fittings are also suitable for the reinforcement of the floor of the garage, plastic ties are used for its compound. You can make it yourself to prepare concrete, using the concrete mixer, but this is a long process, the fill of the floor will require a whole day. You can order a ready-made concrete that will only need to evenly distribute across the area of ​​the garage, although this method will increase the costs.

With independently holding the fill to one person will cope be quite difficult. This is due to the fact that it will be necessary to prepare a large number of concrete, which will leave a lot of time.

At the same time, the concrete for the formation of a monolithic plate is needed immediately, and not parts. If you do not do it right away, subsequently the surface will quickly begin to crack. It is advisable to call someone to help or contact the specialists.

It is better to use low-speed concrete mixer. With it, it is possible to obtain a uniform consistency, which contributes to improving the strength of the finished coating. It will not allow the emergence of air bubbles in concrete, unlike high-breeding concrete mixer. You can purchase a factory mixture of concrete, which must be dissolved with water before use. Due to the fibrovolock, it provides even and durable concrete coating. Optionally, you can add a completion to the mixture.

For concreting, it is better to use cement brands not lower than M300. From the finished mixtures choose M150 brand. Before the fill of concrete, it is necessary to consider the level of the gender of the floor and the finding of gaps. The bias are needed so that the water is evenly flowed, without staying on the floor surface. Most often, such a bias are made towards the goal, it is approximately 2 cm. Clauses should be located within 0.5 cm from the walls.

Concrete Filling Begins after installing beacons. Lighthouses serve as an indicator of solpture. They are placed around the perimeter of the room (along the walls and in the center), secured with galvanized profiles. Lighthouses can be fixed with a reinforcing grid with welding, but it is not at all necessary.

In the role of lighthouses you can use strips or pipes or purchase ready-made materials. Lighthouses begin to arrange from far the walls of the garage to the exit. If air bubbles arise, they need to be removed by a needle roller or vibrator when presented. Special rules need to be dissolved concrete based on lighthouse level. All actions are performed in the direction from the far corner of the room to the exit.

After completion of the floor concreting, it is necessary to water the surface with water and cover the polyethylene film. This will increase the strength of the concrete, and the film will not allow the water to quickly evaporate. For high-quality work, it is necessary not to remove the film for two weeks, but it is better about a month (this will be the interaction of cement with water).

Water watering will provide uniform drying of all layers of concrete. If not to do it, only the upper coating layer is hardening. Over time, this will lead to the fact that the surface will be cracked.

A day after the pouring of concrete, it is necessary to extract beacons, the resulting space should be filled with a solution. In finished form, concrete floor will be difficult to be taken due to the characteristic feature of the coating structure.

Concrete floor coating options are diverse.

To do this, you can use:

  • ceramic or tile;
  • wood;
  • rubber;
  • Coloring.

Last way apply more often. Consider it detail.


Concrete staining does not lose its popularity. Due to this, the modern market presents a wide range of painting materials, which are characterized by a rich selection of shades and textures. When choosing paint, you need to pay great attention to the stability parameter for loads and mechanical damage. The main property of paint is a protective function. For concrete sex with this feature, acrylic or epoxy paints and varnishes are best coped with.

Before applying paint, it is necessary to clean the concrete surface from dust, contaminants, make sure of its evenness and absence of defects. For better adhesion, it is preferable to perform surface treatment by primer deep penetration. It will strengthen the base and forms a film on the surface, which contributes to the maximum paint clutch with the base.

The composition is bought taking into account the type of surface (specially under concrete).

The coloring agent is applied with a roller or spray. Better to paint the surface twice. Apply a new layer only after complete drying of the previous. Masters advise to provide a layer for two days for complete grazing. It is necessary to carry out staining and walls by 20 cm from the floor.

If you compare acrylic, epoxy and polyurethane paints according to properties and wear-resistance parameters, it can be concluded that epoxy coatings are better suited for the garage. They have better resistance to mechanical damage and more adapted to high loads. Coverage of concrete paint protects the floor and transforms it. The color of the paint must be selected in accordance with the general design, based on the fact that pollution should not be noticeable.

Draw painting in the cold room should not: it can badly fix.

Useful recommendations

If the garage is provided for finding the observation pit, the corresponding boiler must be pulled out at the stage of primer preparation. For the convenience and ease of arrangement of the future observation pit it is better to apply a special technique, you do not need to dig. This option is available as long as the walls and the garage ceiling are erected.

Factors requiring attention in the construction of observation pit are:

  • Dimensions of the car, the distance between the wheels of the machine;
  • The dimensions of the garage itself (there must be enough space for the car itself and some maneuvers);
  • Garage’s height and physique (nothing should prevent the inspection and repair of the car).

When calculating the depth of the pit it is necessary to remember the laying of the layer of rubble and sand. So that the garbage and water do not fall into the observation pit, the height of the walls of the pit should be approximately 5 cm (including all layers).

You need to know in advance about groundwater level. If their level goes above 2.5 m, it is not recommended to build a viewing pit. It will constantly drag water, and even waterproofing will not help.

Of great importance is entry into the garage. It is strengthened, reinforced and concrete. Entrance to the garage is usually located under the slope. It can be painted or another type of coating. When staining, it is necessary to handle walls up to 2 cm on the base, paying attention to the joints with the floor.
