Repair and restoration mixture for concrete
The PRR-250 mixture is intended for repair and plastering of horizontal and vertical concrete and reinforced concrete substrates.
Effective in the repair of chips, voids, sinks, bumps and other local defects on the surface of reinforced concrete and concrete substrates, with a layer thickness of 10 mm to 30 mm.
! Do not use for leveling and repairing light concrete foundations and deformable substrates.
It is used for complex repairs of concrete and reinforced concrete structures caused by long-term operation: monolithic frame structures, retaining walls, ramps, columns, balconies, couplers, landings and marches, etc.
