SDE Civils

The name of SDE has always been synonymous with not only the stocking and supply of Drainage and Civil Engineering material but also the extensive knowledge held by our team, meaning we can be relied upon to give excellent advice and service to all of our customers.

We stock in depth, a wide range of civils and construction products for drainage, ducting, access, soil separation and environmental applications. We have strong, long standing relationships with many of the major manufacturers in the sector, including Polypipe, Wavin, Naylor, Klargester, Marsh Industries, F P McCann and Marshalls, to mention just a few.

In addition to this we are a member of the NMBS (National Merchant Buying Society) which gives us access to a massive data base of the major manufacturers of construction materials. From plastic, clay, concrete and cast iron drainage to ducting, manhole covers, geo-textiles and paving to sewage treatment plants and pump chambers, rainwater harvesters and petrol interceptors. We have the expertise to understand what you require and supply it and all at the right price.

All of this makes us the force that we have become in the specialist supply of civils, drainage and environmental products that we are. If you have used us in the past you will recognise that this is correct. If you are looking for a supplier, then don’t just take our word for it, give us a call and let us prove it to you.

SDE Plastics

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.
