Commonly Asked Questions
How does geotechnical polyurethane spray foam work?
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.
What hole size is required for the injection locations?
The polyurethane is injected through 1/2″ metal rods, which are inserted through 5/8″ holes (less than the diameter of a penny.) 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.
