Twinwall Inspection Chambers

Our selection of twinwall inspection chambers caters to the specific needs of deep burial applications and projects requiring exceptional load-bearing capacity. We have a wide range of options that cover both Foul and Surface water systems. Here's what sets them apart:

Enhanced Strength and Durability

Their innovative double-wall design boasts a corrugated outer wall for unmatched structural integrity and a smooth inner wall for optimal water flow. This construction enables the rigid drain chambers to withstand significant external loads, making them ideal for deep installations or high-traffic areas.

Diverse Range of Configurations

• Chamber Diameters: Available in 450mm and 670mm diameters, providing ample access for inspection and maintenance activities within the drainage network.
• Inlet Options: A variety of inlet configurations are available to accommodate different sizes and materials, at different angles to suit the specific layout.
• Depth Options: Twinwall chambers are offered in various depths (1555mm, 2020mm, 2384mm, 1040mm) to ensure a perfect fit for your project requirements.

Compliance with British Standards

All twin wall inspection chambers are rigorously tested and certified to comply with the relevant regulations: British Standard EN 13598-2 (2009), SFA7 & Building Regulations Part H1. This ensures that the chambers meet the highest quality and safety standards for use within your drainage network.
