BIRSS RSM-1 M450 Moroz — fibre-reinforced R4 mix for repair down to −15 °C
Thixotropic repair mix for bridges, tunnels and joints of precast structures, placed at temperatures from −15 to +5 °C.

An economy version of the epoxy system: the quartz filler is already part of the compound, which is applied by pouring. The floor suits the chemical, food and automotive industries, car parks, warehouses and retail. Bond to concrete is at least 2.5 MPa, resistance to acids 10 % and alkalis 50 %, service range −30…+90 °C; light loads are allowed after 12 h and full cure is reached after 7 days.
