Title: Underground fuel tank disposal system - pumps foam concrete in through filler pipe
IPC: B09B5/00
Filed: 1980-07-23
Abstract: The system disposes of an underground fuel tank no longer required so as to avoid environmental pollution. Foam concrete is pumped into it through the filler pipe, so that there is no need to dig it out. The filling operation expels any gas present, and since the concrete is non-aggressive it expels all remaining moisture, so that there is no risk of rusting from the inside, and it absorbs any oil remaining. The specific gravity of the concrete can be matched to the water table, to prevent the tank being forced up out of the ground.
