Deep foam injection is a way of treating the soil at a construction site to ensure the earth is as strong and stable as it needs to be for whatever project is being raised on the site.
For many years contractors have been treating the soil with a polyurethane foam to help bind soil together and increase compaction, resulting in soil that has greater weight bearing ability. Deep Foamjection creates man-made root systems with foam, much like a tree does in nature.
A polyurethane liquid is saturated into the soil, and as it expands into a foam, it fills in all of the air and water pockets that existed in the earth it spreads through. By filling in those gaps the soil becomes firmer and stronger down to whatever depth the foam is injected. This method can lift structures that are already in place that have sunken due to weaknesses in the soil.
What is the difference between Deep Foamjection & Polyurethane Concrete Lifting?
It's all in the depth of the injection. What you raise is only as good as the soil underneath it. With deep foamjection equipment and material, we're able to solve that problem as well, regardless of how old the concrete is or the depth of the unstable substratum.
