Inspection shafts and inspection boxes allow access to the pipes to check their condition, maintain them and, in some cases, change their direction. These are necessary elements for the proper functioning of water management systems. They must be accessible and present at each site of the system: at the beginning and end of the wastewater treatment process and at the main hydraulic nodes of the network. 

Our VISIMOP range, certified NF in monobloc version, is designed to meet the different needs. Lightweight and robust, our manholes are totally watertight (up to 2 metres above the water line) and adapt to all environments, even the most inaccessible. Finally, their vertical and horizontal reinforcements ensure a perfect stability and solidity.
