Rectangular Concrete Chambers

What are rectangular concrete chamber sections?

JDP provide a range of rectangular concrete chamber sections usually used to quickly build a chamber to access utility valves, hydrants and other pipework, or to act as shuttering around another chamber.

They are traditionally used in favour of brick-built chambers, but often superceded by plastic inspection chambers (which are lighter, easier to handle, less resistant to breakage and easier to cut through walls).

Chambers using 600 x 450mm through 1000 x 675mm sections are considered non-man entry, and steps are not required.

Features & Benefits

  • Easy and quick to install when compared to a brick built chamber
  • Concrete sections to take dug out material or concrete backfill
  • Easy access when installed
  • Various sizes available

Standards

Chamber sections and cover slabs are manufactured to BS EN 1917 / BS 5911. Rectangular covers and cover surrounds are manufactured to satisfy Class A15 loading situations to BS EN 124. All units are sulfate resistance class 4.

Heavy duty - cover slabs may be used together with the appropriate duty proprietary cover and frame in main road applications, equivalent to a wheel load of 112kN.
