Manhole Box
A ground support system for forming a concrete manhole.
The Conquip 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 Manhole Boxes are available in 2.5m, 3.5m and 4.0m lengths and are suitable for excavation depths of up to 5.18m.
Unsure whether your excavator has the capacity for these Manhole Boxes? Our Lightweight Manhole Box may better suit your requirements.
