Precast concrete sealed manholes.
For use in both foul and surface water applications
A perfect sealed manhole system available in 1200 mm, 1500 mm and 1800 mm diameters and comprises of a monolithic precast concrete base (available pre-benched in any configuration, a sealed chamber ring (with a thicker wall than a standard ring), a rubber joint (so no tokstrip of similar product is required) and a sealed cover slab which is supplied with your required access.
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, reducing 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.
The sealed manhole complies with BS EN 1917:2002 and BS 5911-3 and has been accepted for use by all major UK companies.
