Precast concrete manholes are the standard product used to provide vertical access to buried pipelines, vaults, detention tanks and various other structures. They are manufactured using modern drycast concrete technology. Manholes are installed using gaskets to provide a watertight product and to reduce infiltration into storm or sanitary systems.

Manholes are provided with cast-in lift inserts for safe, easy installation, ladder rungs for access, and are available in standard 1200mm, 1500mm, 1800mm, 2400mm, 3000mm, and 3600mm diameter sections.


Advantages of Round Manholes over Square and Rectangular Shapes
The use of square and rectangular manholes is becoming common, as more sizes of flat-walled
structures are created, promoted, and installed beneath street rights of way. When looking toward
the new shapes, we tend to forget about the benefits of the classic circular manhole that serves the
infrastructure industry very well.
