REKS® Litoy — pourable R4 grout for bridge bearings and equipment
Low-viscosity non-shrink cementitious mix for high-precision grouting under columns, bridge spans and equipment foundations; 80 MPa at 28 days.

The repair and levelling mortar REKS® Strukto R3 belongs to class R3 per GOST R 56378: it is non-shrink, rapid-setting and fibre-reinforced, with an aggregate size of 1.25 mm. It is used for repair and finishing of concrete and reinforced concrete structures, levelling of surfaces in routine repair and new construction, local correction of horizontal and vertical areas and restoration of precast concrete elements. Flowability is retained for 5–15 minutes, compressive strength is at least 8 MPa after one day and 35 MPa after 28 days, water impermeability from W16.
