The foam will be placed over the holes to allow drainage and the high-backed rear flange serves as the rear flashing which is covered by the building paper to encourage proper drainage. The J-Weep provides straight edge stops for applied plaster stucco and E.I.F.S. as well as offering exacting grounds and protective weeps. It is corrosion resistant and safe for use with thin stone.
J-Weep High-Back Plaster Stop is provided with other ground sizes, including 3/8", 1/2", 3/4" and 7/8" grounds for proprietary one-coat and multi-coat stucco systems.
ES reports require this type of drainage mechanism to meet the requirements of those systems.
