Hercules Non-Shrink Grout HSB 510X, a new formulation of high-strength grout that can simplify and reduce the costs of a range of frequent concrete construction and contractor jobs is being introduced to Australia and New Zealand by long-established bearing manufacturer Hercules Engineering.

Hercules Engineering manager David Booty says the new HSB 510X is a non-metallic Portland-Cement based product formulated to significantly greater strength than standard grouts and which can often substitute for epoxy grouts costing four times as much.

“In addition to eliminating the need for expensive epoxy grout in many applications – on which we provide advice – the water-based HSB 510X formulation is easy to handle and simple to mix to the required consistency of stiffness or fluidity for trowelling or pouring,” he says.

“Also, it will not set rapidly like some epoxy formulations, which can cause wastage and cost time on job.”

The grey, shrinkage-compensated HSB 510X eliminates gaseous expansion while in its plastic storage and also eliminates staining after application because of its non-metallic content, David explains, who has decades of experience in producing a wide range of cost-efficient sliding bearings used in major construction projects. The HSB 510X can be used with these and other bearing types, as well as:

• Grouting underneath pre-cast panels and concrete sections
• Anchor bolt fillings
• Filling in cavities, gaps and base infills
• Filling in core holes created in panels by core drilling
• Block work in core filling
• General purpose uses for retrofitting works where tension cracks often occurs between concrete of different ages.

The new product has a set density of approx. 2,190kg/m³ (flowable/pourable), and has been laboratory tested to more than three times this loading to ensure safety in the applications for which it is intended. It can be applied at a temperature of 10-30°C.
