System No. 1165
Load Bearing Structural Cementitious Grout
This system provides a practical solution for repairing and levelling damaged concrete or masonry surfaces and for forming coves at wall-to-floor junctions to prevent water ingress and make cleaning easier. It combines a polymer-modified bonding layer to ensure strong adhesion with a high-strength, non-shrink repair mortar applied at typical thicknesses ranging from 5 mm up to 50 mm per layer for general patching and profiling. For coving work, a smooth radius fillet is formed with an average thickness of 20–40 mm at the junction to create a seamless, durable detail. This system is typically used for repairing spalled concrete, honeycombs, voids, and edges; profiling precast elements; and installing coves in wet rooms, basements, water tanks, industrial floors, or any area requiring durable waterproof detailing
