Abstract
Subjacent and lateral supporting soil for an underground tank is stabilized wherein a tank embedded therein is secured against flotation irrespective of the water table level of the surrounding soil. The lateral supporting soil is encased within a well and the subjacent soil is hardened to minimize seepage of water into the soil adjacent to the tank. Means are also provided to remove excess water from the confines of the well thereby minimizing flotation pressure on the tank.
