Headquartered in Madrid, Drizoro is committed to innovation, sustainability and high-quality waterproofing solutions.

Our team uses a selection of Drizoro products, including Maxseal, Maxseal Flex, Maxplug and Maxelastic, for sealing, concrete repairs and new projects across the commercial, strata, civil, construction and government sectors.

Among our projects, we’ve provided first-class and large-scale roof waterproofing for hospitals including Concord, Campbelltown, Camden, Bowral, Marrickville, St Vincent’s and Westmead.

And most recently, we opted for Drizoro waterproofing materials to treat walls and floor junctions at RPA Hospital in Camperdown.
