MHCI Access Chamber Installation
Premium Access System

Excavate the required specified location, to the depth of appropriate number of chambers required, (maximum 3 chambers), plus additional 40mm for depth of base. Install chamber centrally within the specified trench/location. Base of excavated area to be well compacted granular material or concrete slab is preferred. Drainage runs within the slab are required to allow excess water to drain freely from the constructed chamber. Before duct connection takes place, the trepanned holes located on each chamber will require cutting out to specified diameter. MHCI Access Chambers take from 63mm to 160mm OD duct pipes.

Allow minimum of 150mm surrounding the chamber for solid concrete support, which should be of a semi-dry workable mixture. Ensure concrete fill is evenly distributed around the chamber and level with the top surface. Concrete the frame in at the appropriate height.

High Strength Composite Duct Access Chamber System
Designed to be a quick-build alternative to concrete or brick built chambers, this high strength structural chamber is manufactured from recyclable durable polypropylene. EasyStack are 150mm deep ring sections that can simply be stacked on top of each other to the required depth to complete a totally load bearing chamber. The twin wall design incorporates internal support ribs which give the finished chamber its inherent strength.

* B125, D400 & F900 LOADINGS

The chamber system has been extensively and independently tested at Lloyds British PLC. These tests have concluded that the chamber design surpasses EN124 B125, D400 & F900 requirements for vertically applied loads. The clear openings available match EN124 access cover and frame dimensions allowing easy pairing of correct chamber to cover.

The twin wall design is 100mm thick providing a suitable bedding area for the access cover frame and subsequent transferral of loads through the chamber, in-line with Highways Agency requirements. The surface area on top of each section is also serrated in the corners for improved adhesion with resin mortars.
