Below Ground Drainage

A 130mm thick wide wall chamber, in combination with the Easi-Base™ unit, provides a sealed watertight manhole system. This robust design means that the requirement for a concrete surround is eliminated.
Quick and easy installation
Watertight structure
Safe anchor lifting system (spherical head lifting system)
Greater cost savings associated with using precast concrete over a traditional system
No concrete backfill required, in accordance with ‘Sewers for Adoption’ 7th edition
More environmentally friendly than a traditional system, almost 40% less carbon emitted during the concrete casting process
Significant reduction in health and safety risks associated with using precast concrete

Please note: Wide Wall Manhole Chambers are manufactured with 3 x 45mm diameter lifting points to facilitate the safe anchor lifting system (spherical head lifting system).

Naylor Metro Access Chamber measuring 300 x 300 x 330mm. Naylor Modular Access Chambers systems are easy to assemble, and designed to interlock at the corners with an integrated mortice and tenon taper lock system. Panels are injection moulded in 100% recycled polypropylene and designed to interlock at the corners with an integrated mortice and tenon taper lock system. The external wall is patterned such that a concrete surround will flow into voids, adding to the structural strength of the system.
Wide internal flange within the chamber enables covers and frames to fit straight onto the box, therefore direct loading is transferred evenly
Panels have trepanned holes which take electricity and utility duct sizes from 63mm to 160mm.
