Most foundation repairs fail because they ignore the geological root cause. Check your soil's Plasticity Index instantly.

Homeowners often ask: "Why are foundation repair estimates so different?" The answer lies in the Geological Profile. Contractors using "cookie-cutter" methods (like pressed piling) often fail to account for the Active Zone depth of your specific soil unit.
The Active Zone is the depth at which soil moisture fluctuates seasonally. In expansive clay, this zone can extend 15+ feet deep.
The Risk: If a pier is installed to 10 feet (Standard), but the Active Zone is 15 feet, the pier will move with the heaving soil, rendering the "repair" useless.
