ABSTRACT:
A foundation watering system includes a ground motion sensor which detects relative movement between a building and a stable soil zone beneath the building. The ground motion sensor includes a hole dug in the earth to a depth below a zone of shrinking and swelling a a rigid element embedded in the stable soil zone and extending upwardly to cooperate with a mechanism on the building. When the sensor detects significant downward movement of the periphery of the building, a valve is actuated to deliver water to the shrinking and swelling zone.
