Building Enclosure Waterproofing

Building Enclosure Waterproofing

Waterproofing is a key aspect of the building enclosure. During and after construction, the waterproofing barrier should be impervious, preventing any water from entering the building enclosure. IIBEC has several resources available for design professionals to learn more about the importance of waterproofing. These resources include credentials, multiple education courses, and published numerous waterproofing technical articles.
