To give the construction industry total confidence in its product performance, Fosroc ANZ has embarked on a major program of independent testing.

Colin Picton, ANZ Specification Manager for Waterproofing and Sealants, said that as part of the DuluxGroup, Fosroc ANZ will not state that its products comply with a particular standard unless it has had independent testing.

He encourages product specifiers and buyers to look closely at technical data sheets (TDS) and question where the test data has come from.

“It might say the material complies with a certain standard, but is the manufacturer relying on its own internal data? We believe the market can have more confidence in external independent testing,” Mr Picton said.

Quality assurance

Fosroc ANZ commissions testing from reputable third parties, including the Australian Water Quality Centre (AWQC), AWTA, Boral, Safe Environments, Cetec, Geotherm Australasia, CSIRO and BRANZ.

“The emphasis on quality is increasing across the construction industry,” Mr Picton said.

In New Zealand, BRANZ approval has become increasingly valued by architects specifying construction products. Meanwhile, in Australia, New South Wales introduced a Building Commissioner and the Construct NSW strategy in 2019, with a view to “improving the quality of construction of residential apartment buildings and restoring trust in the industry”.

“Fosroc ANZ is being proactive and doing the due diligence,” Mr Picton said. “We won’t claim a product complies with a standard just because we believe it complies. We prove compliance with an independent testing certificate.”
