I can't recommend Waterproofing Integrity enough, especially Jean-Pierre! We were dealing with an absolute nightmare of a leaking balcony where the builders and project managers kept making excuses and giving us the runaround. I reached out to Waterproofing Integrity, and Jean-Pierre provided an independent inspection. He was incredibly thorough and found all the hidden issues the builders tried to sweep under the rug – like missing drainage flanges, unsealed penetrations, and blatant building code breaches. But what was the best was his ongoing support. When the project manager tried to aggressively dismiss the report, Jean-Pierre stepped right up, stood by his findings, and gave me the exact technical advice I needed to fight back and demand a proper fix. If you're dealing with dodgy builder excuses or stressful water leaks, do yourself a favor and call this team. Amazing service, bulletproof technical knowledge, and they genuinely care about helping you get a fair result.

Adam demonstrated a high level of professionalism and attention to detail throughout the project. Communication was clear and responsive, and all works were managed efficiently and completed to a high standard. His knowledge, reliability and commitment to quality made the entire process smooth and stress-free. Highly recommended for any construction or remedial works.

I worked with Anthony from Waterproofing Integrity for the first time on this job – What a pleasure it was. The project was a quick 8 level fitout, that had a range of scope for them to assist in. They helped ensure we gave the client the desired result by assisting in planning and documentation, whilst also protecting us and ensuring the products and contractors gave us a compliant installation. The project required them to be very flexible with site visits and they adapted to this at every turn. Even coming in on their days off. I could not speak more highly of the team and won't hesitate to pickup the phone to them on our next venture. Tim

Why Independence Matters

We have no product affiliations. No installer partnerships. No conflicts of interest. Our advice is purely expert opinion: defensible, evidence-based and aligned only with your project’s best outcome.

That independence is why builders, developers and asset owners trust Waterproofing Integrity on their most complex and legally sensitive projects.
