Non-shrink grout is supplied as a ready-to-use dry powder. The addition of a controlled amount of clean water produces a free-flowing, non-shrink grout for gap thicknesses up to 100mm. Non-shrink grout is a blend of Portland cement, graded fillers and chemical additives which impart controlled expansion in the plastic state whilst minimising water demand. The low water demand ensures high early strength. The graded fillers are designed to assist uniform mixing and produce a consistent grout.
