At Danrae Group, we frequently use Sika waterproofing PVC membranes such as Sarnafil G410 for flat roof projects in strata and commercial properties. Sika’s heavy-duty membranes can withstand extremes in climate and adverse weather conditions, and we can use a variety of configurations to meet any project.

Sika’s Sikalastic 590 Plus acrylic primer is ideal for new construction including flat roofs and commercial refurbishment projects. In 2020, we used Sikalastic 590 Plus for our major waterproofing project at Westmead Hospital, as part of it’s five-year redevelopment.
