CRACK ISOLATION

ECB® (Elastomeric Crack Bridging) is the world’s first ever self-adhering anti-fracture membrane. Since its birth in 1983, NAC’s ECB membrane has revolutionized the flooring industry for crack protection and performance.

The ECB family of sheet membranes, when combined with an NAC primer, offers world-class crack isolation protection for both commercial and residential use and same day tile application to expedite your solutions. ECB membranes are rated “Extra Heavy Duty” and reduce down-time, while always providing our signature crack isolation protection.

HOW IT WORKS

How NAC Crack Isolation Works

ECB membranes consist of a base layer of polymer-modified elastomers permanently adhered to a unique “stress flex” fiber sheet. The elastomeric base functions as a buffer by absorbing the thermal and lateral structural movement of the subfloor. Meanwhile, the “stress flex” fiber sheet creates a new flooring surface to accommodate most ANSI A118.4 mortars, organic adhesives and epoxy setting materials. All ECB membranes function also as a vapor barrier, providing Moisture Vapor Protection for up to 10#1000 SF/24hrs when used with an NAC Primer.

The powerful composition of ECB creates a high strength, self-bonding and self-healing membrane that protects the flooring investment. This makes NAC’s crack isolation the ideal peel and stick solution for residential and commercial applications.

ECB® Classic

ECB Classic, the world’s original crack isolation membrane, provides crack isolation protection for up to 3/8” of substrate movement, even in areas of heavy traffic.

Full Product Description

ECB Classic is a 40 mil, self-adhering, sheet-applied elastomeric membrane designed for use under floor surfaces that require protection from structural movement. The peel and stick membrane is permanently adhered to the substrate with an NAC primer while still maintaining the unique flexibility needed to protect against structural movement and cracks. Available in three sizes.

Features & Benefits
  1. Protects up to 3/8” lateral movement
  2. Suitable for interior and exterior use so no area is left without crack isolation
  3. Reduces time and labor costs; ECB Classic eliminates the need to cut tile to meet control/cold joints and tile installation can take place immediately
  4. Performs accurately with radiant heated floors and tile warming systems
  5. Protects against reflective cracking and delamination
  6. Safely covers asbestos flooring and provides an effective barrier against radon and mold
