Underground Drainage

Underground drainage systems help manage a property’s water flow to prevent damage. The term refers to underground drainage pipes and fittings for the system below ground. This includes everything from manhole covers to inspection chambers, twinwall drainage, land drainage and more. 

Our inspection chambers are made from durable, lightweight plastic, and you can choose between two factory-fitted seal sizes. Each plastic inspection chamber in our range is manufactured to BS EN 13598, in accordance with the Sewers for Adoption guidelines. Brett Martin adoptable inspection chambers are available in separate parts so you can customise your system for your project. Chamber risers and bases are also available in standard or shallow access, with various inlet sizes and numbers of plugs. 

You can also find budget-friendly plastic manholes and accessories, such as sewer pipes, chamber seals and socket junctions in this range.
