Abstract: A method of lifting storage tanks by using pressurized bags (12) and support members (22). Lifting the tank allows for visual inspection under the tank for corrosion to prevent leakage of environmentally hazardous chemicals stored in the tank. The lifting bags (12) are placed under the tank (10), inflated, and support timbers (22) placed under the raised tank. The bags are then deflated allowing the tank to rest on the support timbers. The deflated bags raised by placing support timbers under the bags. The bags are again pressurized further raising the tank. The steps are repeated until the tank is lifted to the desired height. Ground suction is broken by raising one side of the tank with the lifting bags, placing supports as far as possible under the tank rim and depressurizing the bags to rock the other side of the tank off the ground. A fulcrum method is also applied to use the partial weight of the tank as a leverage force to alternately raise opposite sides of the tank.
