Taylor Street, Annandale

Building profile: Taylor St is a residential complex in Annandale with 37 units, and 5 townhouses and is approximately 15-20 years old. 

Client: Owners Corporation 

Project Value: $800,000

Works carried out: Balcony & Bathroom Waterproofing

September 5th 2018

For this project the Owners Corporation had previously engaged their own remedial builder, who had attempted to rectify a waterproofing issue on the balconies - and actually succeeded in making it worse. This was resulting in water moving down the building onto lower level balustrades and balconies and causing more damage, including rotting timber. 

The Owners wanted to cut their losses with the existing builder and get us in, so they could have the problem resolved with no further issues. Hitech were not the lowest quote on this tender but our reputation for doing the job properly and following a process won us the job. 

Works carried out 

For the balconies, we had to remove the existing floor tiles off the existing membrane, and then replace the membrane and re-tile the areas. 

All the doors leading onto the balcony area had to be replaced, as the new waterproofing needed to go under the doors to encapsulate and seal the entire area. 

In this case, we also installed additional floor wastes to alleviate water pooling - an example of us updating the design so the remedial works actually solved the existing problem.

Waterproofing of 4-5 bathrooms was also required on this project, which all had been compromised. 

Waterproofing products used

The waterproofing product used for the balcony waterproofing was ARDEX WPM 002, and undertile membrane. This has a rapid drying time - normally we can tile in 16-24 hours - and consists of an advanced acrylic that will not re-emulsify. It is also liquid reinforced which eliminates the need for the use of a reinforcing mat. ARDEX WPM 002 is wet area compatible with fibre-cement sheet, plywood and plasterboard, as well as with concrete, renders and screeds.
