■Necessity of Waterproofing for Wall Penetrations Holes for ducts and sleeve pipes that pass through the exterior wall are often prone to rainwater intrusion, which can lead to leaks. Typically, sealing treatment is performed using caulking, but secondary waterproofing on the interior side of the wall is essential. Furthermore, treatment with only sealing materials is not recognized under the new housing warranty (JIO), and secondary waterproofing is required as a construction standard.
