This precast concrete manhole ring is designed for access to below ground drainage systems in commercial, residential, rail, and infrastructure projects. With an external diameter of 1800mm and a height of 0.5m, it provides a robust solution for forming manhole chambers where foul or surface water systems require regular inspection or maintenance.
Manufactured with double steps to assist safe access, the ring can be positioned quickly thanks to prefabricated lifting holes. It is suitable for installation as part of a modular system to achieve various chamber depths, and is supplied in a natural concrete finish. The product can be handled using appropriate lifting equipment and integrates with standard manhole covers and bases.
