REKS® Graut M — flowable non-shrink R4 grout for machine bases and anchors
Non-shrink highly flowable cementitious mix for grouting machine bases, fixing beams and columns and setting anchors; 60 MPa at 28 days.

Repair and final finishing of concrete and reinforced concrete structures and levelling of surfaces in routine repair and new construction are carried out with REKS® Tikso. The non-shrink fibre-reinforced mortar with an aggregate size of 0.63 mm repairs dormant cracks with an opening of up to 1 mm, protects concrete against media containing sulphates, sulphides and chlorides, and is suitable for local levelling of floors under light and medium loads. Flowability is retained for at least 60 minutes, compressive strength at 28 days is from 40 MPa, water impermeability W16.
