Puddle Clay has been used for hundreds of years mainly as lining in the construction of reservoirs and canals although the product is increasingly used for lining and capping of landfill sites to prevent harmful leaching. Historically Puddle Clay was laid in the base of a canal or lake before sheep or cattle were herded round and round to compress (puddle) the clay until it created a waterproof barrier. Thankfully these days we have excavators and sheep foot rollers to do the job! Features:
