Patent

CA 2353243

A building levelling system is provided for a building having a basement or foundation supported on expansive soil. A water management system is included for maintaining water in the expansive soil at a level adjacent the foundation to saturate the soil with water and thereby prevent the cyclic shrinking and expanding of the soil when the soil is normally repeatedly dried and wetted, causing damage to the building supported thereon. An injection system may also be included for injecting water into the soil spaced well below the foundation to lift a foundation which has already settled significantly due to shrinkage of expansive soil upon which it is supported. The injection system includes a level sensing mechanism for determining when a level of water in a prescribed area of the expansive soil falls below a reference level of the system and injectors for feeding water into that area.
