Large manhole installation: a drainage project in pictures

Installing a new drainage chamber

These photographs record a large manhole installation by Ground to Gable. They show the excavation, the chamber during installation and the formed channel and benching inside the chamber.

From excavation to the chamber interior

The installation photographs show the chamber positioned within the excavation, with surrounding material being prepared. The close-up photographs show the finished internal benching around the drainage channel and the access steps.

Manholes provide access to underground drainage for inspection and maintenance. Chamber installation and associated pipework form part of our drainage and civils work across Kent, London and the South East.
