As a principle, the grouting injections systems should be selected based on the crack or cavity width. The following materials can be selected from the MC-Bauchemie range:• For cracks = 2 mm width – Centricrete• For cracks > 0.2 to 2 mm width – MC-DUR 1264 epoxy system.
Centicrete is a ready to use, hydraulically setting, polymer modified waterproof grout for injection and filling of cracks and cavities. Centricrete injection grout is produced with carefully selected water repellent and silicifying chemical compounds and inert fillers to achieve varied characteristics like water impermeability, non-shrinkage, free flow etc.  Centricrete creates an integral waterproof barrier and prevents water penetration and rising dampness. Centicrete injection grout is suitable for gravity as well as pressure grouting.  This grout is pumpable when the water-powder ratio is about 0.45 to 0.50 i.e. for 30 kgs Centricrete, 13.5 to 15 litres of water.
MC-DUR 1264 is a two component, low viscosity epoxy injection resin for structural repair of cracks. This method of application varies from simple brush treatment to sophisticated two component pressure injection machines. The application time of MC-DUR 1264 depends on the amount of resin mixed and the ambient temperature. The mixing ratio of resin to hardener is 100: 18 Pbw.
