Eco-Soil Expansive Soil Treatment Process

Expansive clay soils shrink when dry and swell when wet—putting constant pressure on foundations, slabs, and structural additions. This movement leads to cracks, misalignments, and long-term property damage. Builders and property owners across the country face delays and warranty issues because of unstable clay soils.
The Eco-Soil Process is Groundworks’ solution for expansive soil treatment. Designed to mitigate swelling clay activity before construction begins, this subsurface chemical injection method helps stabilize soil volume, reduce movement, and protect long-term structural integrity. It serves land developers, homebuilders, engineers, and property owners looking to eliminate risk without costly over excavation.
