Compared with Graut M, REKS® Graut GP is stronger: at 28 days it reaches at least 75 MPa in compression and 9 MPa in flexure, and after one day from 35 MPa. It is a non-shrink low-viscosity cementitious mortar of pourable consistency, class R4 per GOST R 56378, for installing machine bases, fixing beams and columns, fixing bolts and injecting into cavities and ducts. Flowability is retained for 30–45 minutes, freeze-thaw resistance F2 400, water impermeability W16; the grout is approved for use at domestic and drinking water supply facilities.
