Sika grouting technologies are cementitious, resin or polyurethane binders. Engineering grouts are designed to completely fill voids and transfer load. SikaGrout® and Sikadur® are ideal for the filling of - vertical or horizontal joints; - for levelling of interacting concrete surfaces and filling very small holes - Sika cable grouts fill small crevices around post tensioned wires to protect the steel from corrosion.
