Plastic sheet piling is providing bank support for three areas of the Cotswold Water Park between Swindon and Cirencester in the west of England. An alternative to steel or timber piles, Plastic Piling is manufactured by Derby-based HL Plastics from 100% recycled pvc. It is lighter than other materials, making it easier to transport and install. It comes in two forms, Z section, for supporting banks with light use and the stronger Box section, designed to resist heavier soil or water movement. The system was installed by contractor Rangers for client Water Park Society Countryside Services. HL Plastics claims the system is cheaper, more environmentally friendly and will not corrode or rot.
