Download project slidesThe 90'W × 120'L × 18'H shop sits on an old horse arena at approximately 4,300 feet in a high-snowfall area. Its foundation footing is 24 inches wide by 24 inches deep. The owner was concerned that the footing was too small and shallow for the location's snow load and winter conditions. One year after completion, the foundation and concrete slab showed settlement and movement.
Polyflows’ penetrometer testing at 10 locations around the structure identified stable strata. Direct injection of two-component structural polyurethane foam built a structural footing from that strata to the bottom of the existing footing. More than 125 injection sites, including areas beneath 26 support posts, improved the soil's load-bearing capacity and stabilized the structure for its useful life.

Our polyurethane foam also adds to the depth of the frost level to prevent damage caused during freeze/thaw cycles.
We assess the site and test the soil before recommending a repair.
