Manhole Repair Overview:

Problem: The interior of the manhole is crumbling, the connecting pipes are plugging up from years of oxidation and deterioration and small ( and not so small) leaks are allowing ground water to seep into the manhole and sewer line.

Solution: Let our trusted contractors or your own team clean and rehabilitate your damaged manholes.

Rehabilitate your damaged manholes in only two effective and reliable steps for a fraction of the cost to excavate and replace..

Step 1. Preparation

Step 2. Rehabilitation

Step 1. Preparation 

Notice the damage H2S gas has caused to the concrete. Our skilled team members will chisel out the corroded and damaged concrete and then power wash the surface to prepare it for an application of structural concrete with H2S gas inhibitor.

Our technician sprays on structural concrete with H2S gas inhibitor restoring the manhole surface to "Like New" condition. After a short drying time, a coating of H2S gas inhibiting epoxy is sprayed on completing the manhole interior repair.

Step 2. Rehabilitation

A sewer pipe bypass was attached during manhole re-surfacing avoiding the need to shut down the wastewater flow.

The manhole repair has been completed. Wastewater is flowing smoothly from the sewer pipe into the refurbished manhole.
