Frost Expansion Physics
When wet clay soil freezes, it expands upwards. If foundations are not sunk deep enough, they heave, cracking drywalls and structural beams.
Helical Piles and Gravel Backfills
We prevent heaving by using helical steel piles anchored below the 10-foot frost line, and replacing native silt with clean drained gravel pads.
