Ardex Waterproofing

Ardex brand

Sustainable Solutions


ARDEX is dedicated to delivering sustainable waterproofing solutions using carefully selected raw materials. The company invests in cutting edge manufacturing technology to reduce energy usage – and nearly all ARDEX membranes are 100% recyclable.

ARDEX waterproofing products are designed to cover larger surface areas using less materials, including adhesive. And the company’s unique RAPIDRY Formula Technology enables faster project completion, which means fewer trips back and forth to building sites.

With their extraordinary durability, ARDEX products reduce the need for remediation – and resources used over the long term.

Flexibility and Performance


At Danrae Group, we use ARDEX waterproofing membranes for our clients in strata, government, civil, construction and commercial sectors. Some of our favourite products include WPM 300, WPM 1000 and Root Repell.

ARDEX WPM 300 is a water based epoxy and hydrostatic waterproof membrane that prevents rising damp and can be used on surfaces such as basements, retaining walls and carparks.

WPM 1000 is a versatile undertile butynol sheet rubber membrane system for areas such as bathrooms and showers. It has superior strength and waterproofing capability – and tiling can begin just 60 minutes after installation.

Root Repell is a high performance waterproof membrane that repels root growth without killing the roots. We regularly use Root Repell for planter boxes, retaining walls and rooftop gardens, in conjunction with WA98 Adhesive.
