BIRSS 59 S1 M600 Moroz — flowable R4 mix for repairing pavements in frost
Non-shrink flowable mortar for roads, airfields, bridges, floors and equipment foundations, placed from −15 to +5 °C.

Compressive strength of 80 MPa at 28 days and 30 MPa after just one day are the key figures of BIRSS 59 S1 M800. The non-shrink plastic mortar is used for structural repair of horizontal structures: road and airfield pavements, bridge spans and bridge decks, car parks, industrial floors, and for anchoring equipment. Class R4 to GOST R 56378, modulus of elasticity 30,000 MPa, water impermeability W 20, frost resistance F2 400, contact zone Fkz100.
