The PRR-251 mix is ​​intended for repair and restoration of concrete and reinforced concrete foundations, including objects of transport construction exposed loads RCC I, RCC II and
RCC III. Effective at repairing chips, voids, sinks, irregularities and other defects
surfaces of reinforced concrete and concrete substrates up to 30 mm thick with salt
sulfates impact. Do not use for leveling and repairing lightweight concrete foundations and foundations subject to significant mechanical effects.

The PRR-251 is an integral part of the system of  concrete restoration and protection . It is used when performing complex repairs of concrete and reinforced concrete structures caused by long-term operation or destruction under the influence of mechanical loads and corrosion processes – monolithic frame structures, retaining walls, tanks (including for wastewater).
