Which type of built-up membrane is most resistant to slippage?

• A. Asphalt-based membrane
• B. Glass fiber membrane
• C. Polymer-modified membrane
• D. Fiberglass membrane

Answer: (B)

The glass fiber membrane is considered the most resistant to slippage among built-up membranes due to its structural integrity and the reinforcing qualities of the glass fibers. Glass fibers provide a high level of tensile strength and rigidity, which helps the membrane maintain its shape and adherence even under conditions that might otherwise lead to slippage, such as movement, temperature fluctuations, or moisture ingress. In contrast, asphalt-based membranes and polymer-modified membranes, while providing good performance characteristics, may not exhibit the same degree of resistance to slippage because they can be more susceptible to softening under heat or stress. Fiberglass membranes, although they do provide some resistance to slippage, are generally not as robust and versatile as glass fiber membranes when it comes to preventing movement. Therefore, glass fiber membranes emerge as the best option for scenarios where slippage is a significant concern.
