Conbextra HF is a high-flow, non-shrink, cementitious grout for grouting of gap thicknesses 10 to 100 mm. The product comes as a powder which is ready to go and easy to use. The simple addition of a small amount of clean water is all that is needed to produce free-flowing grout. The low water requirement results in high early age strength and exceptional durability. For added peace of mind, Conbextra HF is chloride free and conforms to the requirements of BS EN 1504-3 Class R4 and BS EN 1504-6: Anchoring of reinforcing steel bar.


Uses for Conbextra HF

This product is ideal for contractors, consulting engineers, local authorities, specifiers, builders and anyone looking for pumping grout solutions, even where access to pouring is restricted. It gives a great result whenever there is a need to fix large baseplates, fill joints in with pre-cast concrete, or install tie bars. 

It is the cement of choice when anchoring. Holes simply need to be pre-wetted for two hours or more before starting the job, and then the water removed again before grouting work begins. Once the cement mixture is in the hole a bar can be pushed through it. The special blend of Portland cements, graded fillers and chemical additives produces a fluid material that will not bleed or separate.

A Unique Formula for Success

Conbextra HF offers a unique non-metallic dual expansion system which offsets shrinkage in both its hardened and plastic applications. Early exceptional high strength and very low permeability enables quick installation on site and this has the advantage of bringing operational times forwards, saving time and money. It is highly suitable for pouring or pumping through a wide range of consistencies and in both hot and cold ambient temperatures. For instance, it is ideal for winter working with the grout at low temperature or can be stored differently in the summer months to provide great results even when the weather is warmer. Conbextra comes with plain and simple instructions regarding all aspects of mixing, placing and curing of the grout, so you always know how to achieve the best results.
