Residential Clayboard has been accredited by the British Board of Agrément. The void former products have achieved a mark of quality, safety and reliability that reassures specifiers, merchants and groundworkers that the product that has passed a series of regular comprehensive assessments. The system has a 100% recycled honeycomb core, which is set between lightweight polypropylene facings. Designed specifically for the residential market, the product creates a technically sound void to effectively protect a structure from clay heave damage as a result of ground movement. When dry, Residential Clayboard® is strong enough to support the weight of wet concrete as well as steel reinforcements. Once water is introduced, it has the effect of switching off its compressive strength and leaves a technically sound space. Clay expansion can then be accommodated without exerting undue pressure on the structure above.Benefits:BBA accredited to comply with NHBC standards.Offers a nominal compressive strength of 30 kN/m² when dry.Available in four different thicknesses depending on shrinkage levels.Thinner product saves soil excavation and muck away costs.Sustainable, cost-effective and simple to install on a sand blinding.Lightweight environmentally friendly material.Readily available through our extensive delivery network and preferred suppliers.Delivered to site in a weatherproof seal.No need to calculate safe and fail loads.Size:2440 x 1000 mm.Thickness: - 60 mm:Plasticity index: 10–20.Shrinkage potential: Low.Void requirement: 50 mm. - 85 mm:Plasticity index: 20–40.Shrinkage potential: Low-medium.Void requirement: 75 mm. - 110 mm:Plasticity index: 20–40.Shrinkage potential: Medium-high.Void requirement: 110 mm. - 160 mm:Plasticity index: 40+.Shrinkage potential: High.Void requirement: 160 mm.Strength:The product has a nominal compressive strength of 30 kN/m² when dry and is designed to support the weight of wet concrete up to 1 m thick. When the core is made wet, it will collapse under nominal compressive load of approximately 3 kN/m².598/3528
