Investigation and repair of leakage problems in recently constructed curtain walls

摘要

Waterproofing problems with recently constructed curtain walls illustrate that some, well understood, principles of waterproofing continue to be violated during wall construction. The author finds that divided or fragmented responsibility for the design often leads to the lack of understanding of the waterproofing requirements. New problems are being invented/discovered during the design and construction of these curtain wall systems due to the lack of understanding of the design requirements. Design specifications, workmanship, and the management of construction all contribute to recent problems. This paper presents the author's experience investigating and repairing waterproofing problems in newly constructed curtain walls. The author presents the author's experience investigating and repairing waterproofing problems in newly constructed curtain walls. The author presents examples of design, workmanship and construction management problems that contribute curtain wall leakage problems, and presents a summary of the repair design and implementation.
