Product Description

This unique system of products combines to form the Marshalls CPM Perfect Manhole system; designed and manufactured to last a minimum of 120 years that provides a sealed manhole system that gives up to 40% savings on greenhouse gases compared to traditional manhole construction and eliminates the need of ready mixed concrete to form the traditional base, chamber benching and further concrete to surround the manhole. A complete manhole can be installed in as little as 30 minutes, making safe site practice a real winner when using the Perfect Manhole as it reduces the need to work in confined spaces and eliminates the need for wet trades resulting in rapid construction compared to traditional methods as well as a reduction in the time the excavation is open.

Please note: This manhole ring does not come with steps, if they are required please contact us to discuss this option.

The Perfect Manhole complies with BSEN 1917:2002 and BS5911-3 and has been accepted for use by all major UK companies.
