Abstract
The present invention is a moisture stabilization control system used to prevent structural damage to foundations resulting from forces exerted by the expansion and contraction of underlying soil. Stress sensors are employed to monitor the stress applied against the foudnation. When abnormal amounts of stress are sensed by the system, it compensates for the decreased support of the foundation by injecting water into the soil supporting that foundation until the level of stress is equalized and at the proper amount. The present invention is designed such that it can provide water to the soil in specified zones, thereby relieving localized depletions and preventing substantial structural damage to any foundation.
