RadBox® Access Chamber
RadBox® is a modular preformed underground access chamber system for all types of buried networks and utilities. The RadBox® system comprises wall panels and corner pieces that easily and securely fit together. The system is stackable and is available in 500mm and 150mm heights, which are combined to achieve the required depth.
A vast array of clear openings can be achieved with the RadBox® systems making it suitable for traditional and bespoke projects alike, across a multitude of applications.
Furthermore, our technical experts are on hand to discuss any outsize or specific project requirements you may have.
Features & Benefits
Fully Modular
With RadBox® you can achieve a wide range of clear openings and depths. Modular components such as wall panel corners and joint pins simply slide in and stack together with a secure interlock for maximum build integrity.
Lightweight
RadBox® is manufactured from HDPE, a material with excellent strength to weight properties. The structural foam twin-wall design reduces weight whilst yielding excellent vertical and sidewall strength.
RadBox® panels are safe for manual handling with no need for specialist equipment.
Fast Install
RadBox® has immediate loadbearing strength and offers single step installation, with no need for concrete backfill or raising frame. Installation can typically be completed in less than 1 hour.
Loading
The RadBox® range offers a maximum top load of 40t from 600x600mm upwards. All sizes are suitable for installations in areas rated B125 under BS: EN124: 1994.
Compact Packing
Specially designed furniture simply drops into the unique pocket designs in the chamber walls for a secure fit. No drilling, no fixings and no bolting required. Easy to install and to reconfigure. Range includes drop-in steps, wall brackets and Mobra.
Easy Overbuild
RadBox® lightweight stacking system is ideal for building over-installed duct and reduces risk and disruption to the live network. Duct entries or arches are easily cut with a standard hole saw and the chamber HDPE material, being inert, does not produce any toxic dust.
Sustainable & Safe
RadBox® is manufactured from High Density Polyethylene (HDPE), up to 70% recycled. HDPE is non-polluting and fully recyclable. It is an inert material which does not produce any toxic dust and presents no health risk to operatives or members of the public.
Weather Resistant
RadBox® HDPE material offers excellent weather and chemical resistance. RadBox® can be installed in all types of weather, unlike with concrete or brick-built chambers where conditions can stop work.
