Technical Drawings

With waterproofing, it is essential to comply with the Australian Standards and meet the requirements outlined in the National Construction Code (NCC). In addition, carefully following the manufacturer’s specific instructions is vital to achieving a long-lasting and effective waterproofing system for your project.

At Projex Group, we encourage early-stage involvement in your project, as it allows our team to provide the most accurate advice and deliver a custom-designed Wolfin waterproofing system tailored to your specific needs at no extra cost.

Warranty

  • All Wolfin membrane installations are guaranteed 15 years by a Single Point Warranty on both materials & workmanship. Warranties are issued in favour of the building/structure owner and every Wolfin membrane installation is inspected and signed off by Projex Group/Wolfin Membrane Australia.

 

  • At Projex, we do things differently! We guarantee the work of our Licensed Wolfin Installers for a period of 15 years as well as offering the “standard” warranty on the materials. Our premium Wolfin polyester PVC waterproofing membrane offers strictly controlled detailed applications, meticulous QA inspections, and peace of mind that it is installed correctly. This is achieved with the combination of our accredited, trained, certified Wolfin contractors and the close relationship we share with all our installers. This enable us to keep offering a single point warranty for both labour and material on all Wolfin projects.

 

  • Projex Group is a well established company, that have been supplying the Australian market with Wolfin waterproofing membrane since the late 1980’s. The warranty is issued by us (the supplier) and not the contractors.  It is a single point warranty, so in case of any problems or concerns, you simply have to contact Projex Group for any assistance.
