The system used successfully in standard inspection chambers is now being used in KESSEL road drains, too: telescopic upper cover sections decouple the traffic load from the chamber to the surrounding soil and thus allow the use of weight-optimised polymer chambers.
Their weight of only between 10 kg and 15 kg depending on the chamber variant makes them easy to handle, and on-site installation is child's play.
The monolithic chamber guarantees absolute leak-tightness from the base to the very top and its PE material makes it resistant to ageing, corrosion, frost and de-icing salt.
KESSEL road drains have a unique innovation for the system, a rat protection flap that protects servicing staff from disagreeable
encounters with rodents.
