Manholes have played a pivotal role in the daily function of communities for centuries. They provide ventilation for and access to underground sewer systems, where technicians make connections, perform inspections and undertake maintenance on buried cables, valves, panels, wires, pipes, and other essential equipment. Many of these utility holes are constructed from brick and mortar or concrete, however, and begin to deteriorate when impacted by moisture intrusion and soil movement.
Extend sewer system infrastructure lifespan with manhole rehabilitation services from EagleLIFT, a full-service ground-engineering solutions leader. Utilizing a fast, cost-effective and trenchless polyurethane chemical grout injection process, we can keep vital underground utilities operating for years to come with minimal disruption to the roadways, businesses and residential communities atop them.
Our proprietary polyurethane chemical grout travels into the soil strata and begins to expand immediately within 15-30 seconds after injection. It binds soil media fines together and mitigates inflow, infiltration, and leakage of water. While safe, simple to inject and quick to set, the polyurethane chemical grout is also hydrophobic. It’s not impacted by standing water and will push away moisture as expanding. Other benefits of our polyurethane chemical grout include:
- Expands up to 25 times its initial volume
- Halts further soil settlement
- Increases a soil’s weight-bearing capability
The EagleLIFT rehabilitation process works by injecting a high-density, structural polyurethane chemical grout into the base soils surrounding an impacted manhole through 3/4” metal rods. Once injected, the polyurethane chemical grout expands through all of the voids and into the soil. This works to:
- Fill voids
- Stabilize soils
- Seal cracks
- Connect Leak seal misaligned joints
The polyurethane chemical grout is environmentally inert, and is neither chemically nor biologically reactive and will not decompose. It’s ideal for applications with high water tables or sensitive environmental conditions. Examples include:
- Local, state and federal governments
- Utility companies
- Industrial facilities
- Oil and gas
- Water districts
