About us
What we do
We waterproof the parts of a building that hold water back: bathrooms, laundries and showers, balconies and roof terraces, basements and retaining walls, pools, ponds and tanks.
Most of that work ends up hidden under tiles, screed or soil, so our own job photos show it before it was covered. The membrane is the one layer that has to be right first time.
We mostly use Ardex and Durotech membrane systems, choosing the product for the area: a wet-area membrane under bathroom tiles, an external membrane on a balcony, a UV-resistant system on an exposed roof. Each goes on to the manufacturer’s instructions for primer, coats and cure times, and the certificate names the system used.
We work across Greater Sydney for homeowners, builders, unit owners, owners corporations and commercial property owners.
Each service in detail: bathroom and shower waterproofing, balcony and terrace waterproofing, remedial, strata and commercial waterproofing, basement and below-ground waterproofing, negative-side waterproofing, lift pit waterproofing, retaining wall waterproofing, roof waterproofing, torch-on waterproofing, pool, pond and water tank waterproofing.

Step by step
How a waterproofing job runs
- 1
Photos and questions
You send photos of the leak or the area and tell us what is above, below and beside it. That usually shows what kind of job it is.
- 2
A look on site, if needed
Where photos aren’t enough, we check the substrate, the falls, the junctions and where the water gets in before quoting.
- 3
Preparation and membrane
Surfaces are prepared and primed, junctions get a bond breaker, and the membrane goes on in coats, each left to cure.
- 4
Flood test and certificate
Once the membrane has cured, we flood test it. The waterproofing certificate comes to you when the job is finished.
- 5
Ready for the next trade
We tell you, your builder or your tiler when the membrane is ready to be covered, and nothing should be cut through it after that.
