Waterproofing expensive townhouses by Projex Group

339 Edgecliff Rd consists of 14 large townhouses set up in 3 sections - all with harbour and Rose Bay views. The complex was built in the early 1970s and is on the lower side of Edgecliff Rd, Woollahra.

The buildings have had water penetration problems for over 10 years with water coming in through the roof, balconies and walls.

The Body Corporate engaged Paul Rappaport of The Rapp Report who specialises in Remedial work to advise them on the best way to solve the buildings problems.

Rappaport developed a staged plan for bringing the building up to scratch over a 3 year period.

The water problems were among the first issues addressed. Because of the value of the units and the fact that pervious waterproofing attempts had failed Rappaport recommended the Wolfin Waterproofing System be used to waterproof the roof and balconies and to replace defective cavity flashings.

Wolfin was chosen because of its total reliability and track record in waterproofing structures where other systems had failed. The involvement of the Wolfin people and their supervision of the works was also a key decider.

April Showers, experienced licensed Wolfin applicators and builders, were awarded the contract to carry out the waterproofing and associated works.

After waterproofing the roof and balconies April replaced faulty cavity flashings with the Wolfin system - using the Wolfinsteel profile system together with Wolfin sheet membrane to ensure a cavity flashing which was continuous and was welded direct to the deck membrane leaving no area unwaterproofed.

The recent rains established that the complex was watertight for the first time in over 10 years.
