Inflow and Infiltration Repair
Inflow and Infiltration (commonly referred to I&I) can wreak havoc on sewer infrastructure systems such as culverts, manholes, lateral lines, outfalls, and utility boxes. Inflow and Infiltration is caused when improper connections lead to the inflow of groundwater or stormwater into the sewer system. We use a polyurethane soil stabilization technique to help repair many issues caused by inflow and infiltration, including:
- Sealing against Inflow and Infiltration
- Re-establishing Soil Load-Bearing Capacity
- Soil Densification and Compaction
- Joint Sealing and Stabilization
- Ground Water Mitigation

How it works!
1. Polyurethane is injected into the void through the pipe.
2. Polyurethane begins to expand and pack the voids and weak soils.
3. Once the void is filled, the polyurethane pack and seal the joints.
How do we repair Inflow and Infiltration?
Our polyurethane soil stabilization technique is a process where we inject a high-density polyurethane adjacent to the impacted infrastructure. Once injected, the polyurethane moves throughout the voids similar to how water finds the path of least resistance. After a few short minutes, the polyurethane begins to react and expand throughout the voids, densifying adjacent soils and filling the compromised joints with polyurethane.
The polyurethane is a hydro-insensitive formula, meaning it pushes away any present water and prevents future washout or infiltration by creating a water tight seal.
Here are some of the benefits to repairing Inflow and Infiltration with polyurethane:
- Fast and Minimally Invasive – it requires no excavation and can be completed in hours.
- Minimal Disruption to Traffic – Repairs can be performed from within or above the structure, and can take place during non-peak hours.
- Cost-Effective – with minimal downtime, fast repair, and lower man-hour costs, polyurethane inflow and infiltration repair is very cost-effective.
- Fill Voids and Restore Soil Support – Polyurethane injection fills voids and restores load support back into the soils with one application.
- Lift, Level, and Realign – Level structures such as roadways, outfalls, sidewalks, and rail lines while simultaneously sealing the subgrade infrastructure.
WHY OUR PROCESS IS SO EFFECTIVE FOR INFLOW AND INFILTRATION REPAIR
Our polymer injection application is a no excavation rocking slab stabilization solution, allowing for minimal impact to your structure. Our project footprint is minimal, requiring a small trailer, a hose running from the trailer, and small 5/8″ holes that are drilled through the structure to give us access to drive our rods to target locations and inject our high-density polyurethane.
Our polymers are light-weight and add minimal weight to the area. This is a major advantage because often times treatment is required because the added weight is to much for the geology of the area.
Our polymers set up to 95% capacity within 15 minutes, unlike other solutions which require 24-48 hours and ideal soil conditions. After 15 minutes, the material can be driven on and take on heavy loads.
Our polymers are environmentally inert and have no impact to the environment or groundwater
Not only is our process the fastest and most effective foundation and slab lifting application, but it is the most cost-effective too.
Cost-Effective
Inflow and Infiltration repair with polyurethane foam jacking is a quick and cost-effective solution for rehabilitating compromised culverts, lateral lines, and manholes. The process allows you to keep your current infrastructure without replacement or excavation. By utilizing polyurethane inflow and infiltration repair, the application can be completed in hours with minimal weight added. Additionally, polyurethane is hydrophobic, so it will protect your infrastructure from future soil washout and settlement.
