BIRSS 59 Ts — flowable R2 mix for cracks and joints in industrial floors
Non-structural repair of horizontal concrete and reinforced concrete structures is carried out with BIRSS 59 Ts: it is used to fill cracks in industrial floors, for monolithic joining of rigid joints between concrete elements and for low-pressure injection of voids. The non-shrink mortar based on special cements with aggregate up to 0.63 mm is applied only on concrete and reinforced concrete. Class R2 to GOST R 56378; compressive strength 15 MPa after 3 days and 45 MPa at 28 days, water impermeability W 16, F2 200.
