Today we will tell you about the three most effective, and therefore the most popular, mixtures for the repair of concrete screeds. In this article you will find out which mixture is best suited for urgent repair of concrete, what to use for applying a thin layer and whether there is a universal repair compound.
Which mixture is suitable for creating a foundation for industrial equipment?
Teknogrout EX self—leveling compound is a universal means for repairing concrete screed. It is suitable for correcting irregularities with a depth of 6-10 mm, has a density of 2.3 ± 0.1 kg /l and hardens within 2 hours. It is a one-component mixture that has self-leveling properties, is used as a filling material.
The main scope of application of Teknogrout EX is the repair of concrete planes, railway tracks, connection of prefabricated elements. It is widely used for the repair of helicopter pads, suitable for creating a foundation for large industrial equipment.
The repair mixture is characterized by good fluidity, quickly gains density, is resistant to moisture, chemicals, freezing and thawing cycles. It also does not contain solvents and asbestos, has high adhesion.
What repair mixture should I choose for quick repairs?
Teknogrout Rapid high-speed cement filling mixture is suitable for urgent repair of concrete floors. It is characterized by a high speed of action — commissioning is possible after an hour.

Teknoself single-component self-leveling mixture is suitable for leveling shallow irregularities of several millimeters in rooms with low and medium intensity of operation. The material is self-leveling, has increased adhesive strength, the composition includes a synthetic polymer. The density is 2.8 ± 0.1 kg/l, the curing time is 24 hours.
The main scope of application is the preparation of a plane for laying ceramics, tiles, marble, granite, laminate and carpet as a leveling screed. It is used in residential and industrial construction.
The main advantages are that the substance does not crack with a thin layer of application (from 2 mm), has good fluidity, which ensures ease of operation. The treated surface acquires smoothness, strength and resistance to freezing. When used on an open surface, it eliminates the appearance of dust, which is especially important for the repair of concrete floors in industrial premises.
