Clay heave solutions

Clayboard is the market leader in the void former industry since 1970s and is accredited by the British Board of Agrément since 1998. Clayboard makes 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. 

Clayboard also reduces soil excavation costs. These boards create very little compression and virtually no uplift. Less reinforcement steel is required across the whole foundation site, which can be a significant further saving. Clayboard prevents structural damage to domestic and commercial buildings caused by ground movement. They are made from 100% recycled material. Clayboard is recognised by the NHBC as an appropriate void former for residential properties.

How Clayboard works;

Dry Clayboard is strong enough to support the weight of wet concrete and steel reinforcement. Once the concrete is set, water is introduced to the core. This would degrade the honeycomb centre, which would lead to the creation of a void. This space will accommodate clay expansion without exerting undue pressure on the structure above.

Advertising and digital printing

In 2005 Dufaylite started manufacturing Ultraboard, the innovative honeycomb display panels. Ultraboard is made from recyclable materials. Ultraboard is a lightweight and cost effective, paper honeycomb core board, perfect for digital printing and screen printing. These versatile boards have incredible strength and great eco-friendly qualities. This board can be mounted hot or cold and is an alternative to rigid and foam PVC, MDF, Plywood, corrugated boards. They are made in UK from paper sourced from FSC-certified forests.
