This reducing cover slab is a precast concrete component designed for use within manhole chamber constructions, particularly where a reduction in access opening is required. Measuring 1500mm by 1500mm with a thickness of 175mm, it provides a robust platform over the chamber.
Typically, this type of slab is placed at the top of a manhole structure to cap the chamber and create a base for any additional brickwork before installing a manhole cover. It is suited to deep manhole installations where a change in access diameter or a landing point is necessary during civil drainage works.
