An exterior wall penetration passes through a cast-in-place concrete or masonry wall utilizing a galvanized steel pipe sleeve for pipes smaller than six inches or a ten-gauge galvanized sheet steel round tube for six inches and larger. The sleeve is caulked in place and core-drilled for existing construction with non-shrink grout filling the void, while new construction receives a cast iron wall pipe with a retaining ring serving as an anchor and water stop. The annular space is packed with fiberglass insulation and sealed flush on both interior and exterior sides with a waterproof non-shrink silicone sealant. An escutcheon is installed on the exposed pipe within the finished interior space.
