Tank Renovation in Arahal, Spain

The underground fuel storage tank in Arahal, Spain, with a storage capacity of 12,700 m³, was built without concrete shell in the fifties of the last century.

The steel bottom plates showed great deformations caused by ground water pressure and it showed heavy corrosion.

In 2008 the company Tankbau has got the contract for the complete tank renovation.

A new concrete bottom with a slope to the pump sump was executed on the repaired steel bottom. The tank wall with horizontal stiffeners was covered by a shotcrete wall.

The tba leak protection lining was applied on the tank wall and bottom.
