Drainage Sales offer what is probably the largest range of complete inspection chambers in the UK. Inspection chambers generally come in two diameters, 300mm and 450mm .
The choice is goverened by the depth and the number of inlets required.
Inspection Chamber Structure
The inspection chamber itself is comprised of a base, sectional risers with a seal, and a manhole cover that is specific to the required finish.
Additional risers may be added if required, and the last riser can be cut to size to ensure a perfect match with ground level.
