The one-component finely dispersed expanding compound Profskrin RC462 I, based on highly reactive Portland cement, serves as the basis for injectable structural grouts used to fill voids and cracks, and for soil injection. It is used to install anchors in concrete, soils and rock, to set equipment and steel structures, and to prepare concretes and mortars for repairing road pavements and bridges. Compressive strength from 20 MPa in 24 hours and from 60 MPa in 28 days, water impermeability W16, service from −40 to +100 °C.
