Manholes | Building Supplies

Manholes are essential components of underground drainage systems, providing secure access for inspection, cleaning and maintenance. Designed to withstand heavy loads and harsh ground conditions, manhole bases, risers and covers ensure safe entry to below-ground pipework while keeping the system compliant with UK regulations.

Manhole Cover Options for Driveways, Gardens and Public Areas

A manhole cover protects the opening of the drainage system while providing a strong, stable surface for foot or vehicle traffic. Available in plastic, cast iron and galvanised steel, each manhole cover is rated for different load capacities, making them suitable for gardens, patios, driveways and commercial environments.

Inspection Chamber Systems for Easy Underground Access

An inspection chamber allows for quick access to underground drainage pipes for rodding, cleaning and essential maintenance. With modular risers, secure lids and strong bases, an inspection chamber ensures the drainage system remains functional, accessible and easy to service without excavation.
