Hi Julie, Our chambers are made from HDPE ‘High Density Polyethylene’. The Chambers can be housed via an RC box and backed filled with concrete. Alternatively you can dig down, install a 150mm pad of concrete for the chamber to sit on followed by 150mm concrete back fill. Please refer to the Dual V3 insulation guide link below, see step by step installation instructions of the chamber on pages 9-18. www.deltamembranes.com/app/uploads/2019/02/Dual-V3.pdf
