We now have solutions for ground stabilization, void filling, and water migration that were never before possible or cost feasible.
The polyurethane grouting procedure has exploded into the marketplace and changed how engineers and municipalities are now approaching project solutions. Processes that were once thought as an impossibility or financially impossible are now commonplace. We now have solutions for ground stabilization, void filling, and water migration that were never before possible or cost feasible.
What is Polyurethane Grouting (Chemical Grout Injection)?
Poly-injection is a process in which a single-part polyurethane is injected into granular soils, which permeates the soil and glues the granules together (soil densification). The effective result is similar to sandstone. The compression strength is shown on the chart and white page below.
The data above shows the compression strength difference between untreated sand (20.83 psi) and treated (2985 psi). This compression strength will greatly aid in ground stabilization to support buildings, roadways, bridges, silos, equipment, wastewater piping, etc.
While this ground stabilization process will not help in every situation, the R&D done by Concrete Uprising is freely given to all that are looking for a solution to their individual project in North Carolina.

How the Ground Stabilization Process Is Done
Steel pipes are inserted into the ground at a predetermined distance. The poly resin is then injected with a high-pressure pump at different levels. The resin then permeates the sand over the next 5-10 minutes (depending on the amount of activator used). The resin then solidifies, actually gluing the granules together and forming a rock like structure similar to sandstone.
