HOW WE WORK

Our 6-Step Process for Proven Dependable Residential Waterproofing

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.

WHAT CLIENTS ASK US

Frequently Asked Questions About Residential Waterproofing

Do you offer free inspections?

We deliver professional waterproofing results that improve property protection, durability.

1. What is residential waterproofing and why is it important?

Residential waterproofing involves installing specialised membrane systems that prevent water ingress and moisture damage in homes. It is critical because waterproofing failures are one of the most common causes of structural defects, mould growth, and costly post-handover rectification. Correct waterproofing protects the integrity of the structure, reduces long-term maintenance issues, and safeguards builder and homeowner investment.

2. Which areas of a home require residential waterproofing?

Residential waterproofing is required in all high-risk areas exposed to moisture or water pressure. These typically include bathrooms, laundries, balconies, rooftops, retaining walls, planter boxes, below-ground structures, and other wet or exposed building elements. Each area requires a waterproofing system designed specifically for its environment and usage conditions.

3. What Australian Standards apply to residential waterproofing?

Residential waterproofing must comply with the relevant Australian Standards based on the application.

  • AS 3740 applies to internal wet areas such as bathrooms and laundries.
  • AS 4654 applies to external and above-ground waterproofing applications such as balconies and rooftops. Compliance with these standards is essential to meeting regulatory requirements, supporting warranties, and ensuring long-term system performance.
4. When should residential waterproofing be installed during construction?

Residential waterproofing should be installed after substrates are structurally sound, clean, and properly prepared, and before tiling, finishes, or overburden systems are applied. Correct sequencing allows for adequate curing, inspection, and testing, ensuring the waterproofing system is compliant and ready for follow-on trades without rework or delays.

5. What does a compliant residential waterproofing system include?

A compliant residential waterproofing system includes thorough surface preparation, correct priming, installation of bond breakers and water stops at all junctions, accurate membrane application to the required thickness, and proper curing and inspection. Attention to details such as penetrations, corners, thresholds, and drainage is critical to prevent future leaks and system failure.

6. How does professional residential waterproofing reduce defect risk?

Professional residential waterproofing reduces defect risk by addressing common failure points using disciplined, standards-driven installation methods. Experienced installers follow structured processes that ensure membrane continuity, movement accommodation, and correct detailing. This significantly reduces the likelihood of leaks, call-backs, insurance claims, and costly rectification works after handover.

7. Do you provide warranties and compliance documentation for residential waterproofing?

Yes. All residential waterproofing works completed by Sure Seal Waterproofing are issued with a warranty and compliance certificate. This documentation confirms that the system has been installed in accordance with Australian Standards and manufacturer specifications, supporting builder handover requirements and reducing long-term liability exposure.

8. Why should builders and developers engage a specialist residential waterproofing contractor?

Residential waterproofing is a high-risk trade where errors can have serious financial and reputational consequences. Engaging a specialist contractor ensures accountability, consistent workmanship, and professional coordination on site. A dedicated residential waterproofing provider delivers compliant systems, dependable scheduling, and confidence that critical building elements are protected long term.

9. How do you coordinate residential waterproofing works on active building sites?

Sure Seal Waterproofing works closely with builders, developers, and site supervisors to integrate residential waterproofing seamlessly into construction programmes. Clear communication, reliable site attendance, and readiness for inspection ensure works are completed on time and without disrupting follow-on trades or milestone delivery.

10. What makes Sure Seal Waterproofing different for residential projects?

Sure Seal Waterproofing focuses on compliance, quality-assured workmanship, and reliability. We are not aiming to be the cheapest option — we aim to be the most dependable. Our disciplined processes, experienced installers, and commitment to Australian Standards help builders and developers minimise risk, avoid defects, and deliver residential projects with confidence.
