This 300mm chamber riser is designed for use with polypropylene inspection chambers, providing an additional 400mm in height to help adjust chamber depth as needed for site-specific drainage systems. Made from recycled polypropylene, the riser can be trimmed on site using a fine-tooth saw for installations requiring a custom fit within a recommended reduction limit.
Commonly used to bring access points and manholes to the preferred level, this riser comes complete with a joint seal for straightforward connection. It is suitable for use with compatible chamber bases and manhole covers in both new build and refurbishment drainage projects.
