Twinwall Inspection Chambers

We provide a wide range of twinwall inspection chambers with chamber diameters spanning from 450mm to 750mm as well as a large amount of options for 110mm, 160mm, and all the way up to 300mm inlets in a variety of angles. From this category you should be able to find just the chamber you need, no matter how specific the job is.

Turtle Enviro's twinwall inspection chambers are one piece factory assembled and require no heavy lifting equipment or machinery due to their light weight. All chambers in this range conform to the EN13598 Part - 2 (2009) specification for manholes and inspection chambers in traffic areas and deep underground installations.

Each chamber variant in diameter and inlet selection is available in three depths; 1000mm, 1500mm and 2000mm. Any chamber that has a 1200mm depth or deeper will be supplied with a chamber restriction cap in order to comply with the SfA7 specification.

PLEASE NOTE: Our Twinwall Inspection Chamber range is currently experiencing delivery lead times of 5 - 7 days.
