Fosroc Conbextra HF is used for free flow, non-shrink, cementitious grouting of gap thicknesses 10 to 100 mm. It's advantages include that it is non-shrink, highly flowable, chloride free and is suitable for pumping. Conbextra HF's recommended applications include:
Conbextra HF is supplied as a ready to use dry powder. The addition of a controlled amount of clean water produces a freeflowing grout for gap thicknesses up to 100 mm. In addition the low water requirement ensures high early strength and long-term durability. Conbextra HF is a blend of Portland cements, graded fillers and chemical additives. The filler grading produces a highly flowable grout which will not segregate or bleed.
