Polymer Manhole Covers & Frames
Manholes and Jointing Material
In order to be SABS compliant, underground chambers need to have both a manhole cover and frame. We supply them in a variety of sizes, as well as in two different types of material: choose from ductile iron or polymer concrete manhole covers and frames. Polymer manhole covers are made from a composite material that is bound using resin and fibreglass.
