How Manholes Leak

Manholes leak through degraded pipe connections, cracks, open joints, and defects in the barrel sections. This allows groundwater to enter and wash away surrounding soils. Voids under roads around manholes can cause sinkholes.

Our Grouting Process

We inject polyurethane grout under pressure into the soil surrounding manholes. The grout flows into voids and seals leaks through curtain grouting. This stabilizes soils, fills voids, and stops water infiltration into the manhole.

Polyurethane also seals interior leaks between pipe penetrations, joints, and barrel sections. No excavation is required.

Benefits of Manhole Grouting

• Stops water infiltration and soil erosion
• Fills voids around manholes to prevent sinkholes
• Seals interior leaks and defects
• Extends service life of manholes
• Much less disruptive than manhole replacement
• Significantly more cost-effective
