Course Description: CEU Events: Strategies for High-Performance Below-Grade Waterproofing
Designing a high-performance building enclosure requires more than just surface-level protection; it demands a rigorous, performance-based mastery of below-grade water and gas mitigation. This discussion will provide an expert-level analysis of below-grade waterproofing within the comprehensive framework of the high-performance building enclosure. Participants will examine the fundamental physical forces — hydrostatic pressure, capillary action, and water table dynamics — that jeopardize structural longevity. Participants will evaluate the two most common below-grade application methods: positive-side and blindside (pre-applied) systems, with a focus on selecting successful product and system solutions for complex urban project conditions. We will also explore the key technical performance attributes of different product technologies and types of waterproofing membranes, as well as address passive and active gas-resistant membrane systems for contaminated sites. We will cover how to eliminate scope gaps and foster essential coordination between designers, manufacturers, and contractors to ensure a seamless, high-performance building enclosure. By the end of this session, attendees will be equipped to mitigate the risk of common enclosure failures through evidence-based design and coordinated technical documentation.
Understand where waterproofing is needed across the building envelope.
Identify strategies for waterproofing based on project and design conditions.
Understand key performance attributes for waterproofing technologies.
Develop clear specifications that facilitate coordination and eliminate technical gaps
