Lightweight Manhole Box
A lightweight ground support system for forming a concrete manhole.
The Conquip Lightweight Manhole Box is a simple to assemble, two-sided excavation support system designed to be installed by an excavator using the ‘dig and push’ technique, or by simply carrying out the excavation and then lowering each box into place.
Our Lightweight Manhole Boxes are available in 2.5m and 3.0m lengths and are suitable for excavation depths of up to 4m.
Using a large excavator, or digging a bigger trench? Our standard Manhole Box may suit your requirements better.
