Grade rings are an essential component for any successful construction project involving manholes. These precast concrete rings are designed to fit around the top of the manhole and bring it up to the desired grade level. They are an efficient and cost-effective way to ensure that the manhole is level with the surrounding pavement or ground.

Concrete manhole rings allow for a quick, easy installation. Manhole rings can be easily sealed against the elements. Precast concrete cover slabs are also available which can be used to cap the manhole chamber and reduce the size of its entry point.
