Brick Ledge
We found that there is a brick ledge,however
the waterproofing membrane is cut short. In `
our opinion the waterproofing membrane
should extend to the outside edge of the slab.

We removed the EFIS and a section of brick
above one window to see the existing

above the window. No end dam detail. The
waterproofing membrane is set behind the
window system.

In our opinion the waterproofing membrane

should have been place on top of the window '
frame. In a manner that would force water .
infiltration back out. Also there should be an end

CONCLUSION: In our opinion, a
Ajf
waterproofing membrane needs to be install
under all metal coping and precast capstones.
Voids in the brick mortar need to be fill and the
brick needs a penetrating sealer applied. New t
flashing details need to be installed around all

windows and the base of the wall at the brick
ledge.
