At SDE we have always kept massive stocks of uPVC underground drainage in 110mm and 160mm. This has been the mainstay of our business since we started in 2001. In addition to this we have great knowledge and vast stocks of twinwall drainage, plastic ducting and MDPE pressure pipe systems. In recent years we have developed our range, in line with our customers’ requirements to cover above ground plastic drainage products to include rainwater goods, soil and waste and underfloor heating systems. To compliment this we also stock, in depth, a range of fascia, soffit, cladding and accessories. Across all of our depots you will find experienced, knowledgeable staff, good stocks and dedicated transport.
