Leading the void former industry with a technically sound honeycomb board
Clayboard prevents structural damage to domestic and commercial buildings caused by ground movement. It is used on building sites and is commissioned, purchased and installed by architects, builders’ merchants and ground workers across the country and beyond.
Clayboard is a well-known, trusted brand and is a key corner stone of the Dufaylite parent company. Our products have been market leaders since the 1970s and have been accredited by the British Board of Agrément since 1998. This certification is significant as it means the product has been subject to laboratory tests, on-site evaluations, quality management checks and inspections. It reassures customers that the product is of the highest quality, safety and reliability.
The Clayboard range is known for its ability to solve an expensive problem and is currently the brand of choice for those looking for a reliable void former system that’s going to produce results. Our honeycomb board has been used in high profile commercial and domestic projects everywhere from the New York Subway system to a Cambridge University college.
