ICC-ES AC115
Full Name
ICC-ES AC115 – Acceptance Criteria for Waterproof Membranes for Flooring and Shower Lining
Scope
ICC-ES AC115 establishes the acceptance criteria for evaluating the performance of waterproof membranes used as barriers to positive liquid water migration in specific applications.
Key aspects covered within the scope of AC115 include:
- Load-bearing, bonded, thin-set installations: assessment of waterproof membranes used under ceramic tile and dimension stone on floors.
- Shower sub-pan lining: evaluation of membranes used as shower sub-pan lining to prevent water leakage.
Key performance criteria evaluated under AC115 include:
- Watertightness: the membrane’s ability to prevent water penetration.
- Bond strength: the adhesion of the membrane to the substrate.
- Crack bridging: the ability of the membrane to bridge cracks in the substrate.
- Durability: resistance to degradation from exposure to moisture, chemicals, and temperature fluctuations.
