Sydney Injection Waterproofing Services (One that works and lasts, with a 25-year warranty)

We face very extreme and harsh weather conditions in Australia and many of the variable construction and post-construction projects that are heavily affected by the weather, water table, and underground conditions, face ongoing water ingress problems in balconies, basements, Concrete Crack, and lift shafts.


To combat this, we install our own flexible water-based rubber emulsion injectable product to stop the water ingress issues faced by our clients. Our product, the D-seal system is a two-pack solution that forms a permanent and flexible rubber seal within cracks and fractures in concrete, brickwork, and masonry. The first part of the solution is injected under pressure and permeates the structure replacing the leaking water. Injection and Remedial Waterproofing


The second part of the solution is also injected under pressure and acts as a reactive agent to form the permanent rubber fill. Pressure from water ingress assists in “sandwiching” the D-seal solution into the leaking structure, ensuring a flexible, permanent, and water-tight seal. Work conducted with concrete tidal swimming pools and high negative-pressure basement walls in Australia has proven to be effective, in stopping high-pressure water ingress in a matter of only a couple of hours. Our injectable product has proven to be a market leader and the results we achieve a second to none. This truly needs to be seen to be appreciated. injection and remedial waterproofing
