Our manhole rehabilitation service restores the structural integrity of vertical assets while eliminating groundwater infiltration and inflow (I&I). We apply specialized epoxy coatings and cementitious liners that are engineered to resist the corrosive effects of hydrogen sulfide (H2S) gas commonly found in sewer environments. The process includes rebuilding deteriorated benching and sealing the chimney area to prevent road-salt and debris from entering the system. This comprehensive approach extends the life of the manhole and reduces the burden on downstream wastewater treatment facilities.

• ProtectionHigh-build coatings provide a permanent barrier against corrosion.
• SealingEffectively stops active groundwater leaks and structural seepage.
• RestorationRebuilds internal flow channels for optimized hydraulics.
• SavingsReduces long-term treatment costs by eliminating unwanted inflow.
