Drain Cover

We are the first company in India to introduce precast manholes. Precast manholes consist of three components; namely the base, the riser and the cone. The base, as the name suggests, is the bottom part of a precast manhole and is also where the sewage/water pipe is connected. The cone section is the top most part of a precast manhole and is where access to the manhole is provided. The risers in a precast manhole are mainly there to help achieve the necessary depth from ground level. The wall thickness and grade/type of concrete used will vary based on the technical requirement of the client.

Note : The internal diameter of a manhole can exceed 1500mm, however it cannot be manufactured using precast due to manufacturing and handling constraints. In the case of manhole diameters exceeding 1500mm, the base will have to be constructed using cast-in-situ above which a precast adaptor riser slab will be placed to reduce the diameter for the remainder of the manhole.
