I am starting to plan for my next house and ICF seems interesting at this stage. If I want to waterproof the exterior foundation , can I use WALLTITE Eco polyurethane foam application with a Delta MS dimple as a efficient method ? Does WALLTITE® Eco polyurethane have solvants that will cause harm to the ICF's blocks? Any one here have use that method for waterproofing their exterior foundation ? Many thx ! Eric

Thing is, Walltite is spray foam. That's not really what you want to use to waterproof the exterior foam blocks of an ICF construction. Additionally, even if it was, you'd be left with a rather discontiguous surface (instead of flat).

Maybe look at something like the Polywall system instead. A sausage-tube gap/crack fillter and then a choice between roll-on or spray on wall treatment. followed by peel-and-stick.
