Our Deep Access Box is a lightweight yet rigid chamber which can be easily assembled.

All components lock together, making this product a robust chamber, suitable for a variety of uses.

This chamber system is normally concrete back filled and offers an alternative to rotationally moulded liners, over which our Deep Access Boxes have cost and technical advantages.

All components are made from recycled plastic, strong polypropylene, and are recyclable at the end of use.
