TEC has introduced HydraFlex Waterproofing and Crack Isolation Membrane, a mold- and mildew-resistant membrane designed to deliver superior waterproofing and crack isolation capabilities, according to the company.

The product is typically ready for tile installation within two to three hours, and can be used over green concrete that is only three days old, TEC says. Additionally, the membrane is engineered to stop horizontal cracks as large as 1/8 inch wide at the subfloor.
