Concrete Manhole Rings, also referred to as concrete chamber rings or concrete manhole sections, are used for the construction of access points to both sewage and surface water drainage pipes. These access chambers are usually situated at the beginning and end of a pipe line for inspection or rodding purposes.
They can also often be installed to provide inspection access at any change of direction, diameter or level in a pipeline, or simply at intermediate points along a straight line of pipe.
They provide an excellent alternative to insitu concrete or brick manholes, saving both time and money due to the speed and simplicity of their tongue and groove construction method.
Manufacturer’s Advice: For safety reasons, all chamber sections are loaded and delivered chimney fashion. When offloaded, they should never be stored on their side (on the roll), but should always be laid flat.
