Why Choose NobleSeal CIS Crack Isolation Membrane?

Even minor movement within a concrete slab or substrate can create enough stress to crack tile and grout. NobleSeal CIS helps absorb those stresses before they reach the finished tile surface, significantly reducing the likelihood of costly failures and callbacks.

Unlike liquid-applied crack isolation products, NobleSeal CIS offers factory-controlled thickness and consistent performance across the entire installation. The ability to install tile immediately after placing the membrane also helps contractors complete projects more efficiently while maintaining long-term reliability.

Whether you're installing ceramic tile, porcelain tile, or natural stone, NobleSeal CIS provides dependable crack isolation backed by decades of proven performance.
