      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?

      I really apologize in taking so long to
      respond to you on this.

      The procedure described to you by our rep
      sounds about right except that the Xypex Concentrate will go on first followed
      by the Xypex Megamix I.  This is a system
      that has come to us from the field and has proven successful over the
      years.  This said, waterproofing of brick
      foundations with this system is typically not a one time, install the products,
      and you are done situation.  Brick and
      stone are often difficult to get perfect and typically require at least one
      call back to touch up areas that are persistent leakers.

      We have got a tech bulletin on this system
      although it is not on the web and likely will never be posted there as we like
      to discuss with those attempting this type of project the issues they may face
      ahead of them starting.  Please ask your
      rep for a copy of the tech bulletin if you want it.  If they do not have it ask that they contact
      Tech Services at Corporate to get it for you.

      Good luck with this project.
