This 1800mm diameter by 1000mm deep concrete chamber ring is designed for use in the construction of manhole systems within drainage and civils projects. The unit features a tongue and groove joint profile to support a stable and accurate installation.
Typically, this ring is used on-site as part of standard manhole or inspection chamber assemblies, providing a precast, smooth-finished wall section suitable for underground drainage networks. Compatible with other precast concrete access structures, it streamlines assembly and offers a reliable solution for below-ground access points.
