Heavy duty precision grouting of gaps from 10mm to 125mm, where high flow and high ultimate strength is required. Applications include grouting of:
Conbextra HS, shrinkage compensated ultra high-strength cementitious precision grout, is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a free-flowing precision grout for gap thicknesses up to 125 mm. In addition the low water requirement ensures high early strength and long term durability. Conbextra HS is a blend of Portland cements, graded fillers and chemical additives which impart controlled expansion in both the plastic and hardened states. The filler grading minimises segregation and bleeding over a wide range of application consistencies.
Maximum aggregate size for pumping is 1.0 mm.
