My local representative claims that Xypex products can be applied to brick walls, however I cannot find any literature that suggests that.
My application: Historic multi-wythe brick foundation wall 16 inches to 24 inches thick. The basement is 9 feet tall with half of it being under the street level where portions are exposed with (2) large areaways. We are not digging up the sidewalk to expose the foundation from the exterior, therefore we only have access from the interior side. Our representative suggests parging the brick wall with Megamix-1 and then applying a slurry coat of xypex concentrate over the parging. The concrete slab also receives a slurry coat of concentrate with a water stop (1" deep x 1 1/2 wide channel at the perimeter of the exterior walls) filled with concentrate dry pac.
Is this method appropriate for the brick substrate while also waterproofing the negative side of the wall?
