REKS® Litoy — pourable R4 grout for bridge bearings and equipment

Cementitious grouts

REKS® Litoy, a non-shrink low-viscosity cementitious mortar of pourable consistency, is poured under bearings of columns and bridge spans and under foundations of turbines, generators, engines, machine tools, presses and rolling mills. It is also used to install road safety barriers on highways and for structural repair of bridge structures, columns, beams, piers and treatment plants. Compressive strength is at least 40 MPa after one day and 80 MPa at 28 days, modulus of elasticity 37,500 MPa, water impermeability W20, and flowability is retained for at least 45 minutes.
