Floor Repair: Features and Process Technology

The most common floor under the floor is a concrete floor. Despite the excellent strength characteristics, sooner or later the concrete begins to break down, cracks appear. This leads to the need for reconstruction. Repair of the floor depends on the degree of its wear and the complexity of the problem. In addition, it can take a lot of time and, as a rule, requires skills and the necessary tools.

Repair of the concrete floor may be necessary with several problems, among which:

• Occurrence of cracks as a result of wear or an increased level of vibration;
• Destruction of the upper layer;
• The appearance of irregularities and potholes;
• Destruction of seams;
• Destruction of the screed.

Each of these injuries is amenable to reconstruction, thanks to which it is possible to restore the aesthetics and quality performance of the floor. Consider how to carry out floor repairs, on specific examples.

Fixing cracks

The technology of repairing the formed cracks depends on their depth and the level of destruction of the edge. In the event that traces of the begun destruction of concrete on edges of a crack are visible, it is necessary to spend tape repair. For this, a strip is cut along the crack in the floor, the width and depth of which depend on the degree of destruction. The resulting strip is completely cleaned of dust and covered with a primer based on epoxy resins. After pre-treatment, the cavity is filled with a specially prepared mixture. The surface is leveled and left to dry completely, after which it is ground. In the event that the repair of the floor is caused by deep damage, more than 4-6 cm, the mixture must be applied in several layers.

Minor cracks that have not yet caused serious damage to the concrete cover can be repaired using polymer compounds or solutions containing glue. The main thing is to properly carry out the preparatory work and clean the cracks from the contaminants.

Eliminate potholes and irregularities

Eliminate irregularities by using normal grinding, both mechanical, using special machines, and manual. Repair of potholes is a technologically more complicated process. On the perimeter of the damage, a rectangle is cut out, the depth of which is equal to the depth of the damage. Using an industrial vacuum cleaner, remove dust and debris of building material. The inner surface of the rectangle is treated with a polymer or epoxy composition and filled with a repair mixture. The surface is carefully leveled, dried and sanded.

Restoring the screed

Repair of floor screed can be done in several ways:

• The injection method involves filling the cavity of the exfoliated part with a special compound and strengthening it. To do this, it is necessary to determine the size of the peeling by means of tapping. Using a drill, you need to drill a hole in the surface of the peeled screed and fill the epoxy with a syringe.
• In some cases, by repairing the floor, the screed can be reinforced with reinforcement. To do this, the damaged surface is cleaned of dust and treated with a primer, over which glue is applied. On the treated surface, glass fiber cloth is applied before it dries. The surfaces are allowed to dry well and are impregnated with a special impregnation. After hardening, the plates are grinded.
