Trenchless Pipe Repair with Polyurethane

Leaking stormwater and sanitary sewer pipes lead to big costs for communities and businesses. Typically repairs can be costly and time consuming, shutting down utilities and roadways for days to weeks. Our polyurethane trenchless pipe repair solution is a no-excavation application that is quicker and more cost-effective than traditional methods. 

Polyurethane injection is a fast and effective way to repair a variety of issues that cause pipes to leak. In one application, the polyurethane simultaneously fills voids, densifies soils around the lateral line, and seals leaking joints and cracks in the pipe.

Benefits of Trenchless Pipe Repair with Polyurethane:

How Trenchless Pipe Repair Works

Once injected, the polyurethane aggressively seeks out voids, like how water seeks the path of least resistance. After a few short minutes, the polymer reacts and begins to expand throughout the voids and the weak points in the soil. The polyurethane then begins to use expansive pressure to find the joint separations or cracks.

Step 1

Polyurethane is injected into the void through the pipe

Injections are made through 5/8′ holes that are drilled through the pipe or from the surface. 

Step 2

Polyurethane begins to expand, packing the voids and weak soils

Once injected, the polyurethane travels throughout the voids and expands up to 25 times its original volume through the soil. 

Step 3

Once the void is filled, polyurethane packs and seals the joints

After filling voids, the polyurethane continues to expand, packing and sealing the joints. The polyurethane cures to 95% capacity within 25 minutes.

Why Our Polyurethane Solutions Work

Sealing Manholes and Culverts with polyurethane chemical grout is an excellent method for void filling, soil densification and compaction, and sealing joints and cracks against inflow and infiltration. In a single application all of this can be accomplished.
Trenchless Pipe 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.

We use polyurethanes that are light-weight, reducing added weight to the area. This is a major advantage because often times treatment is required because a structure’s weight is too 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.
