Our versatile and high performing Engineering Clay features low hydraulic conductivity, meaning that it provides an impermeable and watertight barrier.
Produced at our Cheltenham Quarry, our Engineering Clay is perfect for lining ponds, lakes, canals and reservoirs. It is also the ideal material for repairing water channels, flood defences and dams, whether it be on a golf course, fish farm or elsewhere.
It is also used extensively in the lining and capping of landfill cells, in addition to sealing contaminated ground.
