HOW WE WORK

Our 6-Step Process for Proven Reliable Waterproofing Services

1.
Preparing The Surface

We prepare the surface by cleaning, repairing cracks, and creating the necessary slope towards the drain. The surface must be structurally sound and stable as well as clean, dry, and free from dirt, grime, or any loose particles.

2.
Applying Primer

We apply a suitable primer that will seal the very small holes within the surface and ensure that the waterproofing membrane will adhere properly. The primer will prevent air bubbles in the membrane.

3.
Installing Bond Breakers & Water Stops

We install mandatory bond breakers for all floor-to-wall and wall-to-wall junctions to allow for structural movement without tearing the waterproofing membrane. We install water stops to contain water.

4.
Applying The First Coat of Membrane

We apply the first coat of the waterproofing membrane to the primed surface and detailed areas like corners and pipe penetrations.

5.
Applying The Second Coat of Membrane

After the first coat has dried completely, we apply a second coat to ensure a comprehensively thick waterproofing membrane that is free of any holes or gaps.

6.
Flood Testing & Inspection

Once the second coat has fully dried, we block the area and pour water to test for leaks.

1. Why is compliant waterproofing critical for builders and developers?

Compliant waterproofing is essential to protect the structure, minimise defect risk, and meet regulatory and warranty obligations. Waterproofing failures are one of the most common and costly causes of post-construction rectification, often resulting in significant delays, insurance claims, and reputational damage. Correct installation from the outset helps builders and developers avoid long-term liability and costly call-backs.

2. Which Australian Standards must waterproofing systems comply with?

Waterproofing systems must comply with the relevant Australian Standards for the application type. This includes AS 3740 for internal wet areas such as bathrooms and laundries, and AS 4654 for external and above-ground applications including balconies, rooftops, and podiums. Compliance ensures durability, performance, and the ability to issue warranties and compliance certificates.

3. What areas of residential and commercial projects are considered high-risk for waterproofing?

High-risk areas include bathrooms, laundries, balconies, rooftops, planter boxes, retaining walls, podium decks, and below-ground structures. These areas are exposed to constant moisture, weather conditions, or hydrostatic pressure and require professional waterproofing to prevent water ingress and structural deterioration.

4. How do you ensure waterproofing systems perform long term?

Waterproofing is installed using a strict, methodical process that includes detailed surface preparation, priming, installation of bond breakers and water stops, application of multiple membrane coats to the required thickness, and flood testing where applicable. This process accommodates structural movement and ensures the system performs as intended before handover to the next trade.

5. Do you provide warranties and compliance documentation for projects?

Yes. All waterproofing works are completed with a warranty and compliance certificate, confirming the system has been installed in accordance with Australian Standards and manufacturer specifications. This documentation supports builder handover requirements and helps reduce defect and warranty exposure.

6. Who do your waterproofing services support?

Sure Seal Waterproofing works with residential builders, multi-residential developers, commercial builders, and project teams across Melbourne and the Sunshine Coast. Our services are tailored to suit detached housing, multi-unit developments, and large-scale commercial projects, with a strong focus on compliance, coordination, and reliable delivery.
