About your waterproofing guarantee


Generally, a waterproofing guarantee relates to your waterproofing membrane. We triple test every membrane installation, which includes testing from the supplier. Once they are happy with the quality of installation, we provide full details of the brand warranty at handover.

Depending on the brand, a materials warranty can last 10, 20 or 30 years. Keep your membrane in pristine condition and the manufacturer might even extend your warranty, and sometimes by years.

While a membrane warranty is imperative, so is the quality of your workmanship, and that’s where we stand apart. In addition to your warranty, we also provide a full workmanship guarantee, something still quite rare in our industry.

Our standard waterproofing plans include the usual manufacturing warranty… and our six-year installation guarantee.

Our preventative maintenance plans


To provide even further protection on completion of your roof waterproofing, Danrae Group also offers our clients a choice of optional roof waterproofing maintenance plans.

Our waterproofing maintenance is the best way to protect your membrane warranty. We’ve tailored our plans to provide you with full flexibility for maintenance that best suits your budget and the specific needs of your strata, commercial or government property.

Our roof waterproofing maintenance helps keep your waterproofing in great shape… and that will help preserve the integrity and value of your property.

Different Roof waterproofing maintenance plans

At Danrae Group, we think long-term, so we never opt for a quick fix. And a key part of your waterproofing solution is preventative maintenance.

We have three levels of optional roof waterproofing maintenance plans – giving you full flexibility for maintenance that best suits your property.

While a standard plan comes with our six year guarantee, there are even more benefits with our Gold and Platinum packages, including extended installation warranties and manufacturer warranties, annual inspections to rectify minor issues, site documentation and testing certificates.

Preventative maintenance is the smart choice for long-term waterproofing effectiveness.
