Footing capillary break vs. bonding of masonry to footing
I am an architect in Ohio where we often use CMU for foundation wall, especially on addtions. I’ve been showing “damp proofing as capillary break over footing” on my wall sections based on GBA recommended details. I recently got a question from a mason about this. He had never heard of this detail, and was concerned that it would create a bond break, preventing the mortar from properly connecting the block to the footing. Is his concern a valid one?
