This course examines the material composition, reinforcement types, and testing standards associated with styrene-butadiene-styrene (SBS) modified bitumen membranes. It explains how fiberglass, polyester, and combination reinforcements affect membrane strength, flexibility, and dimensional stability. The standards that establish testing methods for tensile strength, elongation, and long-term performance are covered in detail. The course also outlines how material selection and installation practices influence roof durability, moisture resistance, and occupant safety.

Upon completion of this course, the Learner should be able to:

  • Identify the primary reinforcement types used in SBS-modified bitumen membranes and their corresponding ASTM designations to ensure material selection that supports structural integrity and waterproofing reliability.
  • Explain how reinforcement composition and structure affect key physical properties, such as tensile strength, elongation, and dimensional stability, and how these properties contribute to the long-term safety and performance of roofing assemblies.
  • Differentiate between ASTM and CSA standards governing SBS membranes to confirm compliance with codes, testing protocols, and quality benchmarks that protect public health, safety, and welfare.
  • Recognize how SBS membrane reinforcement properties, installation practices, and standards support building durability, waterproofing integrity, occupant safety, and overall system performance.

Approximately 1 hour. Delivered online, at your own pace.
