The Perfect Manhole System is available in 1200mm, 1350mm. 1500mm and 1800mm diameters and comprises of:

  • A monolithic precast concrete bases (available pre-benched in any configuration within just days of requisition).
  • A sealed chamber ring.
  • A rubber joint or butyl sealant strip.
  • A sealed cover slab which is supplied with your required access.
  • A sealed pipe connection for various pipe types.

 

 

This unique system of products combines to form the Perfect Manhole system. Designed and manufactured to last a minimum of 120 years. This is 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 and chamber benching.

The Perfect Manhole can be installed in as little as 25 minutes, reducing the need to work in confined spaces, helping safe site practice, 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 Perfect Manhole complies with ISEN 1917:2002 and IS420 and has been accepted for use by all major UK and Irish companies.
