Puriton®  PDM are Scottish Water Framework Holder Approved Suppliers

A tried and tested barrier pipe and fittings system for contaminated land.

Developments in Polyethylene manufacturing technology have made it possible to combine polyethylene (PE) with other materials, including aluminium, which possess excellent barrier properties. With governments encouraging the redevelopment of brownfield land, there is a need for a new polyethylene pipeline solution that will ensure the protection of our drinking water against soil contaminants found in brownfield sites.

To ensure that the barrier properties of the Puriton® system are maintained, only Puriton® fittings are approved for use with Puriton® pipe. The use of non Puriton® fittings may compromise the barrier properties of the system.
