Parchem Construction Supplies

Parchem brand

Parchem Construction Supplies has been a mainstay in the Australian construction industry for over 50 years, and Parchem is a leading supplier of construction materials to both the Australian and New Zealand markets.

Known for its innovation, the company has spent years developing its own line of quality Parchem waterproofing products from its test laboratory in Wyong, NSW. It now has an extensive range of superior construction materials, equipment and tools that are widely used throughout the industry – and by the Danrae Group team.

Thanks to expansion, locally made Parchem waterproofing products are also now exported to regions including Asia, Europe and the Middle East.

Parchem waterproofing applications

Parchem waterproofing products are suitable for a range of applications including basements and rooftops.

At Danrae Group, we regularly use Parchem’s Nitoprime Zincrich and Renderoc during concrete repairs.

Nitoprime Zincrich is the recommended anti-corrosion primer for exposed steel reinforcement and it’s specifically designed for use with Renderoc concrete repair mortars.

Another favourite is Nitoproof 750, which is suitable for basements, flat roofs and tunnels.

We’ve used Parchem waterproofing materials for several clients, including a major project at ANSTO (the Australian Nuclear Science and Technology Organisation) in Sydney.
