High Level Concrete Tower


High Level Concrete Water Tower

The high level drinking water storage reservoir within the top of the water tower, underwent a full internal refurbishment in 2017.


After removal of the existing failed waterproofing system and surface preparation to the concrete walls and floors, all expansion joints were sealed using a joint overbanding system, and all concrete surfaces received a cementitious waterproof levelling mortar to provide a blow hole free and consistent surface for the subsequent coatings.

After cure of the levelling mortar, heating and dehumidifaction equipment was installed to ensure that the correct applications conditions were achieved within the tank.

Acothane LV sealer was applied to all concrete surfaces, followed by a first coat of Acothane DW cream at a minimum of 0.5 mm thickness, followed by a second coat of Acothane DW blue at a minimum 0.5 mm thickness, giving a final waterproofing system at a minimum of 1 mm thickness.

All heating and dehumidifaction equipment was removed, and the Acothane system was allowed to cure for a minimum 7 day period at 3 degrees or above.
