Flooring: features and process technology

The Most common reason under the floor is a concrete floor. In spite of the excellent strength characteristics, sooner or later the concrete begins to break down, crack. This leads to the need for reconstruction. Floor repair depends on the degree of wear and the complexity of the problem. In addition, it can take a lot of time and usually requires the skills and necessary tools.

Repair a concrete floor may be necessary for several problems, including:

• The appearance of cracks due to wear or excessive vibration;
• The destruction of the upper layer;
• The appearance of bumps and potholes;
• Destruction of suture joints;
• The destruction of the screed.

Each of these injuries is amenable to reconstruction, thanks to which manages to bring back the aesthetics and quality performance floor. Consider how to repair the floor on concrete examples.

Seals cracks

The Technology of repair of cracks depends on their depth and level of destruction edge. In that case, if traces of incipient fracture of concrete along the edges of the cracks, is to hold a tape repair. For this purpose along the cracks in the floor cut strip, the width and depth of which depend on the extent of destruction. The resulting strip is fully cleaned of dust and coated with a primer composition created on the basis of epoxy resins. After preprocessing, the cavity is filled with specially prepared mixture. A surface level and left to complete drying, and then polished. In that case, if the floor damage caused by deep damage of more than 4-6 cm, the mortar must be applied in several layers.

Minor cracks that have not yet caused serious damage of concrete cover, can be repaired using the polymer compositions or solutions which contain glue. The main thing is to carry out preparatory work and clean the cracks from dirt.

Eliminate potholes and bumps

To Eliminate irregularities can be by conventional polishing, such as mechanical, using specmsheni and manual. Repair of potholes - is technologically a more complicated process. Around the perimeter of the damage cut out a rectangle whose depth is equal to depth of damage. Using an industrial vacuum cleaner, remove dust and residues of construction material. The inner surface of the rectangle is treated with a polymer or epoxy compound and fill mortar. The surface is carefully leveled, dried and polished.

Restoring the screed

Repair of the screed floor can be done in several ways:

• Injection method involves filling a special part of the cavity of the detached part and strengthening it. This requires using tapping to determine the size of the detachment. Using the drill, you need to drill into the surface of the detached tie holes and using a syringe to fill in these holes with epoxy composition.
• In some cases, repairing the floor, the screed can be strengthened by reinforcement. To do this, the damaged surface is cleaned of dust and is treated with a primer, over which glue is applied. On the treated surface until dry, before it is overlaid with fiberglass. Give the surface to dry thoroughly and apply a special impregnation. After curing, the patch carry out the grinding.
