Underground Drainage Fittings for Secure, Watertight Connections

Our range of underground drainage fittings and accessories is built for secure, long-lasting connections in below-ground drainage systems. These underground fittings are designed to meet UK performance standards, helping manage foul water and surface water flow in residential, commercial, and infrastructure projects. Whether you’re working with 110mm or 160mm pipe, our fittings ensure leak-resistant joints and dependable structural performance, even in high-load and variable ground conditions.

Manufactured from high-quality uPVC, each component offers excellent chemical resistance and structural integrity, even in challenging environments. The smooth internal profile of our underground fittings helps reduce the risk of blockages, while their lightweight design allows for straightforward handling and installation on-site. Choose from a full selection including bends, couplers, junctions, reducers, and adaptors to create custom drainage layouts that meet specific site requirements without compromise. Many fittings feature push-fit or solvent-weld joints, supporting fast and leak-free connections that reduce installation time and long-term maintenance demands.
