The PRR-223 mixture is intended for the comprehensive repair of concrete and reinforced concrete structures caused by prolonged use or destruction under the influence of mechanical loads and corrosion processes – monolithic structures, retaining walls, tanks, ramps, ramps, balconies, etc.
Effective for repairing chips, voids, sinks, bumps and other defects on the surface of reinforced concrete and concrete structures, the permissible layer thickness is from 5 to 30 mm.
! Do not use for repairing light concrete, cement-lime, cement-sand, gypsum and other weak surfaces.
