Why MaxiChamber 450
The MaxiChamber 450 gives you dependable access to underground drainage in a 450mm chamber, with a configuration for shallow and deep runs alike. Choose a 110mm, 150mm or 160mm chamber base to match your pipework, each moulded in recycled polypropylene. Every base includes blanking plugs for unused inlets and has a lightweight design, so handling and installation are straightforward without heavy lifting. A range of access covers lets you match the chamber to the project.
Lightweight and easy to handle
Each component is easy to carry and position on site. The twinwall shaft is lightweight too, so deeper installs avoid heavy lifting.
Made from recycled polypropylene
The bases and risers are moulded in recycled polypropylene, giving you the strength and durability underground drainage demands. It lets you specify a lower-impact product without compromising on long-term performance.
Choice of 110mm, 150mm or 160mm connections
The 110mm base takes 110mm pipe with 45° and 90° side branches. The 150mm base takes 150mm twinwall pipe and the 160mm base takes 160mm pipe, each with a 45° x 110mm side branch and a 90° branch to match its pipe size. Blanking plugs are included for any unused inlets.
Watertight and secure
Risers can be supplied with 450mm sealing ring to give a watertight system, and can be cut to your preferred height. Covers and frames are available in 15kN and 35kN, meaning you can match the cover to the loading at each location.
