Mixture PRR-215 is a professional special repair and assembly solution that quickly gains strength (after 30 minutes. The strength of the solution is about 15 MPa), which allows work to be carried out in a short time.

Wide range of applications in road construction, civil engineering, metallurgy, mines, etc.

In road construction for quick and high-quality installation of storm water inlets, sewer, telephone, gas, water supply, electric wells and hatches (it makes it possible to restore traffic in 30 minutes even at air temperatures down to -5 ° C). For the installation of traffic lights, road signs, concrete and metal road barriers. For quick repair of airfield runways.

In construction, for the repair of cracks and potholes in concrete, brick structures, in structures made of natural stone. For filling holes in places where utility lines pass through structures, repairing cracks in concrete and other structures that allow moisture and water to pass through.

Also used for repairing water leaks in mines, adits, concrete pipes, etc. It is prohibited to use for repairing lightweight concrete, as well as cement-lime, cement-sand, gypsum and other weak surfaces.
