Each product bears the Polypipe Terrain hallmarks of high quality construction and reliability in use and all are backed by the company’s outstanding technical advice and customer support service.

Sustainable Products

Finding sustainable product solutions is another of our ongoing commitments. The rainwater harvesting system together with other water management solutions such as sustainable drainage systems (SUDS) are examples of a range of environmental management solutions that Polypipe Terrain can offer.

Sustainable Materials

Plastics – which feature among the most researched materials in the world – are integral to sustainable development. Thinner, lighter and more robust than most traditional materials thanks to continuous technological innovation, they help reduce energy use – and therefore greenhouse gases.

Sustainable Processes

Polypipe Terrain has always been committed to reducing waste and to recycling as much as possible of what we do produce. These commitments apply to our manufacturing processes, recycling, waste policy and transport. Everyone at Polypipe Terrain understands the importance of contiunuing to develop sustainable processes in everything that we do.
