Terracotta-coloured PVC drainage fittings are a staple of UK housebuilding and civil engineering. Used in underground soil, waste, and surface water drainage systems, these fittings must deliver precise colour matching, reliable mechanical performance, and resistance to the aggressive chemical environment found below ground level.
Our terracotta drainage compounds are formulated for injection moulding — optimised for complete cavity fill in complex fitting geometries including bends, junctions, reducers, and access chambers. The pigmentation system delivers batch-to-batch colour consistency that matches the terracotta shade expected across the UK drainage market.
Every compound is engineered for the demands of below-ground installation: resistance to soil chemicals, root intrusion pressure, and ground movement. We source formulations that meet the requirements of BS EN 1401 for underground drainage — giving your finished fittings the performance credentials the market demands.
