Geotechnical Foam Can Help Soil Erosion

Soil erosion can be a major problem, especially in cities where a small amount of erosion can threaten the foundations of multiple buildings. The soil that's eroded also causes problems -- it clogs drainage systems, allowing more water to build up, and increase the erosion rate.

One of the most effective ways to prevent soil erosion is with geotechnical foam. A polyurethane product similar to the spray foam used  to insulate homes, geotechnical foam is easy to apply. It provides a barrier to water and to wind, reducing erosion.

At NCFI Polyurethanes, we recommend using the TerraThane geotechnical foam materials for your construction projects. This product is 100% compatible with the natural earth, so we don't have to worry about it reacting poorly with the surrounding soils.

The first step in applying the TerraThane is to identify the areas in or around the structure that are leaking water or allowing air to seep through. Once these leaky spots are identified, a thin tube is used to apply the geotechnical foam. The foam begins as a liquid mixture, and the liquids react to create a space-filling foam that cures in place to seal cracks and cavities.

Geotechnical foam is both strong and light. It stands up to wear over time, and it does not add considerable weight to structures, so it does not interfere with their delicate engineering. Using geotechnical foam is a lot less expensive and time consuming than other options, which, depending on the situation, can involve removing and replacing entire structures.

If you're interested in using TerraThane to stop erosion of your structures, contact NCFI Polyurethanes. We offer top-quality materials for your construction projects, including spray foam, spray foam applicators, and more.
