What are twinwall land drainage pipes?
As Builders merchants in Devon you’d expect us to know! Twinwall land drainage pipes (also known as twin wall) are light but strong land drain pipes made from recycled plastic. They have a ribbed outer surface and a smooth inner bore. They are usually black in colour. Normally they come in 6m lengths and the most popular sizes (which we stock at Willand) are 150mm, 225mm,300mm, 450mm and 600mm diameters. Twinwall land drainage pipes are available in unperforated and semi-perforated forms. The unperforated land drain pipes are used as carriers. The semi perforated land drain pipes can be laid perforations upward to collect water, and perforations down to disperse water. We keep a good range of couplers and seals, and junctions & bends for the smaller diameters.
