How to waterproof and insulate old foundation walls from the outside?
Is 2″ XPS over dimpled membrane over blue skin a good idea? Should the foam go up all the way from footing to the rim joist which is 3′ to 4′ above grade? Or is it better to stop the foam at grade level? If going up is better choice, how to protect and finish the above grade portion of the foam? The foundation is 8″ concrete block which is flush with brick veneer of exterior walls. Location – Ontario, Canada. Your input will be very much appreciated.
