Abstract
A novel foundation system, method of manufacture and method of implementation are disclosed, comprising a simplified cast structure/pile combination advantageously shaped for selective positioning in different soil conditions to become a supporting foundation. In at least one aspect, the shape comprises a cavity or shaped recess that is initially empty, and operable to accept soil displaced by soil heave. The cavity preferably is configured to have a depth estimated to be equal to or greater that an estimated vertical heave displacement of a given site soil, in order to minimize soil heave displacement of the cast structure/pile combination. In at least one other aspect, the shape comprises a portion configured to cleave soil if the soil heaves.
