Our Process

• The polyurethane is injected through 5/8 inch holes (less than the diameter of a quarter).

• The holes can be made through the structure, such as a foundation slab, roadway, or lateral line pipe, or can be made through adjacent soil depending on the proximity to the treatment location.

• Once injected, the polyurethane is initially in a liquid form that finds the path of least resistance, filling annular voids and saturating loosely compacted soils.

• The polyurethane then begins to expand and densify, compacting the adjacent soils and sealing joints against inflow and infiltration.
