Manhole Rehabilitation

Manhole Rehabilitation


Manhole Services You Can Trust

Manholes include many components and are made of different materials. These parts and materials each serve a different purpose and contribute to the complete manhole structure. Each component has specific repair and renewal requirements because each has its own set of possible defects. PowerVac completes manhole rehabilitation for facilities of all sizes.

A variety of problems on the pavement surface can lead to catch basin failures. These problems should be addressed as soon as possible to avoid costly repairs in the future. If you notice damages of any kind, it’s time to call a professional. The main structure is no longer secure if there are signs of blocks and bricks deteriorating. Stress from driving or parked vehicles create further damage and you then face the risk of the entire top structure collapsing.

Tuck Pointing or wash outs are the main reasons manholes fail. This is when the mortar inside the joints or the top ring of the basin deteriorates, allowing water to enter the structure through the bricks instead of the top grate. This water causes erosion and freezing during the winter months. Blocks and bricks are displaced fly the ice and affects the structure.

After the manhole rehabilitation has been completed, the existing cast iron frame and lid will be reinstalled on the new basin and reset at the correct height to ensure proper drainage. The excavated area will then be back filled, leveled, and compacted. We will then provide either asphalt mix or concrete which will then be poured or rolled to match the existing grade. A pre-build concrete structure with adjustment rings will be installed and connected to the existing drainage lines in the event that the entire manhole needs replacing.
