Innovative honeycomb void formers
Our unique sustainable honeycomb board solutions create a technically sound void, solving ground movement issues and prevent structural damage caused to foundations by clay heave.
The honeycomb core is set between lightweight polypropylene facings and is installed on a polythene sheet in the foundation zone. Water is introduced after the concrete slab is set, which impacts the honeycomb, leaving a sound void that allows for natural ground movement to occur without exerting pressure on the ground slabs above.
Up to 50% thinner than competitor products, Clayboard also reduces soil excavation and muckaway costs. As our boards create very little compression and virtually no uplift, there’s no need for clients to calculate fail and safe loads with our void formers. This means that less rebar steel is required across the whole foundation site, which can be a significant further saving.
We work with structural engineers, builders merchants and contractors across the world to design and rollout environmentally friendly void former systems that have been tailored to their specific requirements. Available at resellers across the country, we can manufacture to a four day lead time. Our team has many years of experience working on a range of projects, including everything from complex commercial developments to the New York subway system.
