Impervius Waterproofing Membrane
Brad backs his balcony membrane work with a 10-year guarantee and a signed-off plan before lifting a tool.
The reviewer walked through the full job lifecycle: inspection, scoped quote, proprietary materials, a 10-year guarantee, and a tradesperson who showed up when he said he would and dealt with mid-job complications himself rather than flagging them as extras. Brad is named directly and described as 'a real professional in an industry not known for them' — which is a pointed observation from someone who apparently had prior bad experiences in this trade. Before hiring, it's worth asking him to clarify what his 10-year guarantee covers specifically (materials, labour, or both) and whether he carries public liability and waterproofing-specific insurance for apartment work, since balcony waterproofing failures can trigger strata claims.

About Impervius Waterproofing Membrane
Brad, the operator behind this Angus-based waterproofing business, handles balcony and membrane waterproofing on residential apartments — a niche that sits at the intersection of building defects and strata liability, where shoddy work causes ongoing internal damage that's expensive to remediate. What sets Brad apart from generalist waterproofers is his diagnostic approach: he inspects first, builds a detailed remediation plan, and provides a written quote before touching anything — a process that reviewers note is uncommon in this trade. He works with proprietary waterproofing materials and backs his installs with a 10-year guarantee, which is a meaningful commitment in a category where warranty disputes are common. The single review on record specifically praises his punctuality and his ability to troubleshoot problems mid-job without passing those complications back to the homeowner. Based on what's documented, he suits apartment owners dealing with leaking balconies causing internal water ingress — especially where previous work has failed or a strata body needs a professional sign-off. With roughly a decade in business and GST registration, he operates as a structured company rather than a sole trader side-hustle.
Best for: apartment owners dealing with balcony leaks causing internal water damage, residential waterproofing jobs that need a diagnostic inspection before work begins, and clients who want a written plan and long-term guarantee before committing.

What type of waterproofing work does Impervius Waterproofing Membrane specialise in?+
Based on the available review, Brad focuses on balcony and membrane waterproofing for residential apartments — specifically situations where a leaking structure is causing internal water damage. He uses proprietary waterproofing materials and follows a process that begins with a thorough inspection and a detailed written plan before any work begins. This suggests he's better suited to remedial and diagnostic work than new-build applications, though it's worth confirming your specific job type when you call.
Does Brad provide any guarantee on his waterproofing work?+
Yes — the one documented customer review mentions a 10-year guarantee was provided as part of the job. That's a substantive warranty commitment for waterproofing work, where failures can take years to surface. Before you sign anything, ask Brad to clarify in writing what the guarantee covers: whether it includes both materials and labour, and what the process is if a leak reappears within the warranty period.
What areas does Impervius Waterproofing Membrane service?+
The business is based in Angus, NSW. Reviews don't specify how far Brad travels for jobs, and there's no publicly listed service radius. Given the specialised nature of balcony membrane work, it's likely he operates across a reasonable geographic range, but you should confirm your location with him directly before booking an inspection.
Is Impervius Waterproofing Membrane suitable for strata or body corporate jobs?+
The reviewed job involved a leaking apartment balcony causing internal damage — exactly the type of defect that often triggers strata involvement. Brad's approach of providing a detailed written plan and quote before starting work aligns with what strata managers typically require. However, reviews don't explicitly mention strata experience or waterproofing certification documentation, so ask him directly whether he can provide compliance paperwork if your building requires it.
How does Brad handle unexpected problems that come up mid-job?+
The one available review specifically notes that Brad 'solved any problems as they arose' without pushing complications back to the client — which suggests he doesn't use mid-job surprises as a lever to renegotiate the quote. That said, one review isn't a pattern, so it's worth asking him upfront how he handles scope changes and whether any variations would be quoted separately before proceeding.
