Crack Isolation Performance
Independent laboratory testing using the Robinson Floor Tester confirmed that Composeal Gold provides exceptional crack suppression capability. It helps protect tile installations from common substrate movement and shrinkage cracks found in residential and commercial construction.
Direct Bond Technology
The outer layers of non-woven polyester are heat-fused to a PVC core at high temperature, allowing tile to bond directly to the membrane while preventing delamination.
Waterproof Protection
The inner layer uses the proven Composeal PVC shower pan liner technology, delivering reliable waterproofing protection and helping prevent moisture migration beneath tile installations.
Applications
Ideal for new construction and renovation projects using ceramic tile, porcelain tile, marble, brick, or natural stone in residential and commercial installations.
Warranty
Composeal membranes are designed to last the life of the building. The membrane itself is warranted against manufacturing defects; warranty applies to the material and not installation conditions.
