Water damage is one of the most costly and disruptive problems you can face—whether it’s a leaking shower, cracked balcony, or compromised bathroom membrane. At Activ Plumbing Solutions, we deliver expert waterproofing services across Jervis Bay and the South Coast, using industry-best practices and quality materials to keep water where it belongs.
Our licensed professionals are highly experienced in all aspects of waterproofing—from bathrooms and balconies to rooftops and retaining walls. We work with homeowners, builders, body corporates, and commercial property managers to ensure watertight results that meet Australian Standards (AS 3740-2010) and the Building Code of Australia.
Understanding Waterproofing and Why It Matters
Waterproofing is the process of applying barriers or membranes to prevent water ingress into a building structure. Without proper waterproofing, moisture can creep into walls, floors, ceilings, or balconies—leading to rot, mould, and structural damage.
We provide waterproofing solutions for:
- Bathrooms – including showers, floors, and wet areas
- Balconies and Decks – exposed areas prone to leaks
- Roofs and Flat Roofs – especially with torch-on membranes
- Retaining Walls – preventing moisture from seeping through garden and structural walls
Our Waterproofing Process
Each job is different, but our professional process ensures the best result every time:
1. Site Inspection and Assessment
We inspect the affected area and assess any existing damage or leak pathways. This helps us choose the most effective waterproofing method.
2. Surface Preparation
We clean, dry, and prime surfaces, removing any old membranes or debris to ensure maximum adhesion.
3. Application of Waterproofing Membrane
We apply a liquid membrane, sheet system, or crack injection (depending on the area), ensuring full coverage and flexibility for movement.
4. Joint Sealing and Detailing
Junctions, corners, penetrations, and wall-floor intersections are reinforced with sealant or bandage systems to prevent future failures.
5. Curing and Final Inspection
We allow adequate curing time before testing and completing a final inspection. For bathrooms and balconies, we ensure the area is tile-ready.
