When SDE started in 2001 we were a stockist of above and below ground plastic drainage products. This mainly consisted of soil, waste, rainwater and 110mm/160mm underground drainage.
Now we are a major stockist of all types of construction plastic pipes. Stormwater and ducting up to 600mm diameter are stock items. We also stock MDPE and barrier pipe and fittings for the supply of potable water. Complementary to our pipe ranges are duct boxes and rainwater attenuation crates, which are also stock items.
Stockists of 110mm and 160mm PVC Drainage Systems to BS EN 1401.
