Crack Suppression Capability

Independent laboratory testing supervised by the Ceramic Tile Institute of Los Angeles confirmed Composeal Gold's ability to help protect properly installed thin-set tile systems from common substrate movement and shrinkage cracks found in residential and commercial construction.

Direct Bond Capability

The outer polyester layers are heat-fused to the waterproof membrane core, allowing direct bonding to both the substrate below and the finished tile installation above. The heat-fusion manufacturing process helps prevent delamination while providing exceptional long-term performance.

Waterproofing Capability

The waterproof membrane core is based on proven Composeal waterproofing technology and provides dependable moisture protection beneath tile and stone installations. This waterproof barrier helps prevent water migration and protects surrounding building materials from moisture-related damage.

Installation Information

Install Composeal Gold using approved thin-set mortar methods. Use the included curb protectors, inside corners, and flexible vinyl cement to properly seal critical waterproofing transitions and penetrations.

Proper substrate preparation and installation techniques are essential to achieving maximum waterproofing and crack isolation performance.

Warranty Information

Composeal 30 and 40 mil membranes are warranted against material failure. In the event of a membrane defect, replacement material will be supplied at no charge. Warranty coverage applies only to the membrane itself and does not extend to installation methods, consequential damages, or conditions beyond the manufacturer's control. Under normal conditions, Composeal membranes are designed to last for the life of the building.
