The World’s Best Bridge Deck Waterproofing Membrane.

In mid 2015 Equus Armac were contacted by Vic Roads to present a waterproofing solution for a 2,000m2 section of Melbourne’s Westgate Bridge that was in need of repair.
Equus Armac, together with The Parkinson Group, who were the main contractors for the project and Poly-Tech Industrial Services, the Equus Armac approved applicator, commenced works on the 27th of December, with a 10 day application schedule. After only 4 days (and fortuitously right on New Years Eve) the works were completed much to the delight of all concerned, due to it’s ease of application and fast cure times. Combined with it’s excellent waterproofing properties, very high impact and puncture resistance and it’s ability to withstand stress and movements in the substrate, the Armac Matacryl WPM System proves yet again that it is indeed The World’s Best Bridge Deck Waterproofing System.
