Waterproofing the new high end retail and residential 38 acre site in Minneapolis was a massive undertaking. The WetSuit® membrane was chosen for it’s ease of application due to its spray system delivery as the deep below grade vertical walls were accessed by surrounding sand hills. This difficult terrain posed numerous hazards to hot rubber systems. Laborers would literally be forced to “Billy Goat” the terrain with pails of melting hot rubber, as Tom Wickstrom, CEO of Spec 7 Group stated. Spray delivery allowed rapid, and safe, installation of monolithic WetSuit® membrane. Additionally, multiple truck courtyards were waterproofed in between slab applications. We thank Spec 7 Group for their true grit and determination throughout difficult weather and unforeseen challenges.
