CSU Grout is a Portland cement based product with the addition of water resistant polymers designed for placement in saturated and under water situations. CSU Grout has high strength, good flow and non-shrink properties. Placed grout gives structural support and good vibration resistance. CSU Grout is chloride free and can be safely used in contact with steel.
Placement thickness may be in the nominal range of up to 100mm above water and up to 200mm when placed under water. For thicker sections 6mm Aggregate should be added at a rate of up to one to one Aggregate to CSU Grout. Aggregated mixes should be made in a standard concrete mixer.
Grout placement may be made by pouring or pumping in tidal zones or under water without significant loss of fines and cement.
