Proper below-grade waterproofing design requires compliance with the International Code Council’s International Building Code (IBC). The code is very specific in regard to important waterproofing design elements. Sections of the code establish basic design criteria including where waterproofing is required, when waterproofing is required and how it is to be applied. Some of the key sections of the 2012 IBC that affect waterproofing design are highlighted in this article. Architectural Roofing & Waterproofing will explore this information in greater detail on Sept. 17 in an ARW University Webinar titled “Waterproofing Design by Code Requirements.”
1805.1 General. Walls or portions thereof that retain earth and enclose interior spaces and floors below grade shall be waterproofed and dampproofed in accordance with this section, with the exception of those spaces containing groups other than residential and institutional where such omission is not detrimental to the building or occupancy. Ventilation for crawl spaces shall comply with Section 1203.4.
