Clark-Drain launches new polypropylene B125 chamber.

Published:  22 January, 2019

The new B125 access chamber from Clark-Drain has been specifically designed for traffic signals, street lighting and communication networks. 

Constructed of 100% recycled polypropylene, it delivers optimal safety, longevity and strength whilst being lightweight, durable and saving time on site for electrical and groundwork contractors.

Available in clear opening sizes of 300mm, 450mm and 600mm widths, the chamber provides easy and safe installation and maintenance access to underground utilities.

Compared with traditional brick chambers, the new B125 chamber has push-fit connections, allowing interlocking panels to be assembled quickly to accommodate the recommended depths for different utility applications. Sliding T-Slot corner connections aid levelling and assembly, and trepanned entries allow standard duct entry diameters to be drilled with no measuring or marking.

Chamber panels are injection-moulded in 100% recycled polypropylene, topped by a composite access cover with galvanised steel louvre frame. The unique honeycomb structure of the chamber panels allow concrete to flow into the voids, adding to the overall structural strength.

The non-ferrous B125 composite cover is non-conductive thus protecting pedestrians against voltage dispersion especially in wet environments. Resistant to chemicals, deformation, rust and corrosion, the cover is designed to provide optimum product life span.

The cover also reduces noise pollution when installed as the composite material has a low density, deadening footfall and traffic noise. With minimal risk of theft, as polypropylene has no scrap value, and a PSRV slip resistance value of 60, it is ideal for pedestrian and light vehicular traffic up to 12.5T total weight.

This quick to install chamber also has a B125 load rating classification and supports the Specification for Highway Works relating to the minimum depths of excavation for ducts and cables laid under verges, footways or open ground and is designed and manufactured in the UK.

Clark-Drain is committed to providing the right, total solutions for building projects. The B125 is the latest in a range of chambers available from Clark-Drain, who also produce the heavier duty D400 and E600 chambers for roads and more heavily trafficked areas.
