ICC-ES AC29
Full Name
ICC-ES AC29 – Acceptance Criteria for Cold, Liquid-applied, Below-grade, Exterior Dampproofing and Waterproofing MaterialsScope
ICC-ES AC29 outlines the requirements and test procedures for evaluating liquid-applied materials used for dampproofing and waterproofing below-grade exterior surfaces. The scope of AC29 includes:- Material properties: evaluating the physical and chemical properties of the liquid-applied materials, such as viscosity, solids content, and resistance to water absorption.
- Performance testing: conducting standardized tests to assess the materials’ resistance to water penetration, hydrostatic pressure, and crack bridging.
- Durability testing: evaluating the materials’ resistance to aging, weathering, and chemical attack.
- Quality control: establishing quality control measures for manufacturers to ensure consistent product quality and performance.
- Application requirements: providing guidelines for the proper preparation of surfaces and application of the materials to ensure effective dampproofing or waterproofing.
- Asphalt-based: typically used for dampproofing, providing a barrier against moisture.
- Polymer-modified asphalt: offering enhanced performance and flexibility compared to traditional asphalt.
- Polyurethane: providing excellent waterproofing properties and resistance to chemicals and abrasion.
- Cementitious: typically used for waterproofing, forming a strong and durable barrier against water.
