Inspection chamber

KALA-drain attachment for safe retention of coarse dirt particles and prevention of deposits on the drain


The inspection chamber reliably retains coarse dirt on green roofs, preventing it from accumulating at the drain. Avoids larger dirt deposits while ensuring full drain functionality. The chamber cover can be removed for inspection purposes.

The inspection chamber is placed centrally on the drainage point above the drain. The gravel basket is then inserted into the opening and clamped into place. Following this, the chamber cover is placed on top. Gravel is then pushed against the inspection chamber on all sides to fix it into place and provide a filter layer in front of the green roof substrate. Do not fill the substrate directly against the inspection chamber.
