We produce lightweight carbon negative aggregate for use bound in concrete blocks, ready mix or unbound as pipe bedding, as general fill (6F2/6F5) or road base. Some of the aggregate products can be used as a substrate on living roofs, providing more alkaline conditions to support, for example, chalk grassland vegetation. The aggregate is comparable to IBA aggregate or other secondary lightweight aggregates as defined in EN13055.

A range of other construction blocks can be manufactured from agricultural or biomass residues cemented by carbonating their ashes combined with cement, providing much needed construction products for the purpose of sustainable development.
