This partial void causes a decrease in the upward pressure of the soil, resulting in the lowering of the outer perimeter. This method raises the slab to its original height and provides future support in case the hydrostatic pressure is relieved again. The piering system works very well to immediately raise the slab and close existing cracks, but it does not stabilize the soil. Therefore, the original cause is not being corrected, and the same problems will reappear in the future. Foundation experts agree that moisture stabilization is necessary to prevent further damage.
Soil stabilization treats the cause, while piering systems merely treat the symptoms.
The Micro-flo Moisture Control System is a permanent solution that not only addresses the symptoms, but the true cause of foundation failure due to expansive clay soils. What took 5 to 10 years for nature to deplete, our system can replace in a few months.
