A contractor proposed a Westcoat 6 or 7 step fiberglass or lathe waterproofing system for a decent sized residential deck (13x13ish) that is the roof of a inhabited interior area and will have fairly light traffic (it's off a bedroom). (This system is probably Westcoat ALX, but checking to see if it is MACoat). The waterproofing membrane is a slurry (polymer modifed cementitious) that dries solid and then has additional cementitious layers over it. There is no rubber or plastic continuous membrane. In this application the warranty requires inspection & maintenance every 2 years.
The maintenance schedule is not ideal. I would rather have something with a longer maintenance cycle but don’t know the alternatives.
Does anyone have experience with this system and have any comments, concerns, endorsement or condemnation?
