ECB® Anti-Fracture Membrane

The first self-adhering Elastomeric Crack Bridging (ECB®) anti-fracture membrane ever available, ECB® is the original fast track solution for sameday tile installation. 


How It Works

ECB® is a self-bonding, sheet applied elastomeric membrane and is designed for use under floor surfaces that require protection from structural movement.


ECB® consists of a base layer of polymer modified elastomers, permanently laminated to a unique "stress flex" fiber sheet. Together they form a single 40 mil (1/16") thick, high strength self-bonding membrane that is easily applied. The elastomeric base functions as a buffer, absorbing the thermal and lateral structural movement of the sub-floor (up to 3/8"), while the "stress flex" fiber sheet creates a new flooring surface which will accommodate most ANSI A118.4 mortars, organic adhesives and epoxy setting materials.  ECB® adheres permanently to the substrate, remains flexible and will last the life of the flooring surface.



Use ECB® membrane OVER:


Concrete: Poured, pre-stressed and pre-cast concrete, concrete backerboard, mud beds, gypsum, lightweight concrete and patching compounds. 


Wood: Plywood, APA-rated sheathing, Sturd-I-Floor, hardwood, tongue and groove and OSB with standard face. (Gap between sheeting as required.) 


Other Substrates: Ceramic and porcelain tile, stone, terrazzo, VCT/VAT, metal, painted and sealed floors and floors damaged by dry shrinkage and structural movement. 




Thin & medium-bed mortar installations (ANSI A118.4) of ceramic, porcelain, stone, marble, slate, granite tile, pavers, brick, hardwood, manufactured wood, commercial grade vinyl and other finished floors are also acceptable; check with manufacturer.


Ideal for use with radiant heated floors and low voltage tile warming systems.



ECB® is available in three sizes:

3'x50' rolls for full floor coverage and soft joint relocation,

2'x50' rolls for use with large tiles over structural cracks

1'x50' rolls for strip applications over non-structural cracks
