Why Wolfin & Cosmofin Are Ideal for Waterproofing in South Australia?

South Australia’s climate conditions, from hot, dry summers to winter rainfall, require high-performance waterproofing solutions that can withstand:

Extreme UV & Heat Resistance

Wolfin and Cosmofin are designed to withstand Adelaide’s intense sun and high temperatures, ensuring long-term durability.

Winter Rain & Coastal Exposure

The fully welded seamless membranes provide reliable waterproofing in high-rainfall areas, heritage buildings and coastal zones with Stainless Steel profile options available.

Chemical & Root Resistance

Suitable for planter boxes, podiums, and green roofs, commonly used in modern commercial developments in Adelaide and SA.

Long-Term Reliability

Wolfin is the only waterproofing membrane in Australia with a single point 15-year material and workmanship warranty, offered by the supplier. Cosmofin comes with a 20 years material warranty, a standard across the waterproofing industry.

Whether for high-rise developments, new or remedial waterproofing projects, Wolfin & Cosmofin provide unmatched protection for SA construction.
