Heligrout 25
A very high performance, non-shrink, non-gassing thixotropic, cement-based grout for use with the application of the HeliTie Bar. Each tub contains the dry powder and liquid component individually packed to ensure that consistent results are obtained with every mix.
HeliGrout has been specially formulated to bond equally well to masonry as with the HeliTie, thereby bonding the HeliTie Bar to the substrate. Structural reinforcement is only as good as the bond of the HeliTie Bar to the masonry.
Introduction
HeliGrout 25 is a non-shrink, pumpable, thixotropic, high performance, cement-based grout suitable for injection with a hand applicator.
The 16 litre bucket contains the dry powder and liquid component individually packed to make either 3 or 6 litres of injectable grout.
The low liquid to powder ratio ensures a thixotropic grout which develops its compressive strength rapidly. It is designed to fill all the voids into which it is injected and the bond stress is greatly enhanced by its expansive properties.
Uses
HeliGrout 25 is suitable for bonding metal components into most masonry substrates including concrete, brick, stone, blocks etc. It is designed for use with the other helical stainless steel products - helical bar, brick bars and some wall ties - as a bonding agent. Further details can be obtained separately on these products.
HeliGrout 25 has been found to be an ideal alternative product to polyester resin and is particularly useful when fire risks are an issue, for example replacement wall ties on high rise structures. Being non-flammable and odourless the grout does not have the inherent drawbacks of many resin based alternatives.
Packaging
The packaging of the grout ensures that consistent results are obtained with every mix. There is nothing to leave out and, more importantly, nothing to add. Contractor error is therefore practically eliminated. The grout is available in three different sizes; 1L contains enough mixture for 1 litre, 3L contains enough mixture for 3 litres of grout whilst 6L contains two packs of each 3L component and hence products 6 litres of usable grout. All sizes are packaged in a bucket for a clean mix every time.
Allow 1L for 3 x 1M lengths of HeliTie Bar.
Allow 3L for 10 x 1M lengths of HeliTie Bar Allow 6L for 20 x 1M lengths of HeliTie Bar.
Storage
The HeliGrout 25 buckets may be stacked up to 4 high and should be kept in dry conditions. A temperature range of 5 C to 35 C is ideal and should be maintained.

Why HeliGrout?
HeliGrout has been specially formulated to bond equally well to masonry as with the HeliTie, thereby bonding the HeliTie Bar to the substrate.
Structural reinforcement is only as good as the bond of the HeliTie Bar to the surrounding masonry.
