ABOUT THE PRESENTER

Kevin Lin
Kryton International

Kevin Lin works with engineers, building envelope consultants, contractors, and ready-mix producers throughout British Columbia to improve the durability and watertightness of concrete structures. His work focuses on integral waterproofing systems, concrete durability strategies, and long-term performance of below-grade assemblies.

Kevin began his career in the building envelope sector with Cascade Aqua-Tech Ltd., where he supported consultants and contractors with waterproofing, air barrier, and building enclosure systems. This experience provided him with a strong foundation in building envelope design, detailing, and construction coordination.

Today at Kryton International, Kevin works with design teams across the Lower Mainland to help integrate concrete durability and waterproofing strategies into structural assemblies.

Before entering the construction industry, Kevin was a classically trained symphony musician who performed with the Vancouver Symphony Orchestra and earned a Master of Music from Carnegie Mellon University. His background in orchestral performance shaped his appreciation for complex systems — where precision, coordination, and attention to detail determine long-term success.

ABOUT THE TOPIC
Integral Concrete Waterproofing Systems: Best Practices for Durable Below-Grade Structures

Crystalline concrete admixtures have been used in concrete waterproofing since the mid-1980s. Over time, the category has expanded from a small number of manufacturers to a wide range of products, often grouped together under the general term “crystalline admixtures.” However, these products rely on different chemistries and mechanisms, and their performance characteristics can vary significantly.

This presentation reviews current best practices for specifying and implementing permeability-reducing admixtures for waterproofing applications. The session begins with an overview of American Concrete Institute (ACI) Chapter 15 guidance on permeability-reducing admixtures, which provides a framework for selecting admixtures based on performance requirements and exposure conditions.

The presentation also reviews independent testing conducted by the British Columbia Institute of Technology (BCIT) evaluating permeability reduction, shrinkage crack mitigation, and self-sealing behavior in accordance with ACI recommendations.

The session concludes with practical guidance on incorporating crystalline admixtures into a complete integral waterproofing system, including detailing for construction joints, pipe penetrations, control joints, and repair of defective concrete. The goal is to help design teams understand how integral waterproofing systems can be detailed and coordinated across stakeholders to improve long-term watertightness and durability.

Learning Objectives
After attending this presentation, participants will be able to:
1. Understand ACI guidance related to permeability-reducing chemical admixtures (PRAs) and how these classifications apply to waterproofing design.
2. Differentiate performance characteristics between various types of crystalline and permeability-reducing admixtures used in concrete waterproofing.
3. Interpret independent test results related to permeability reduction, crack mitigation, and self-sealing capabilities.
4. Apply best practices for detailing integral waterproofing systems, including joints, penetrations, and repair strategies.
5. Recognize coordination requirements between designers, contractors, and concrete suppliers when implementing integral waterproofing systems.
