However, as noted in the gure, through-wall ashings generally create a bond-breaker, which reduces the structural capacity of a masonry wall. The tapers are typically either 45 or 22.5 degrees. Non-extruding versatile offers a minimum of 70% recovery after compression. The product and aqueous emulsion reacts with calcium hydroxide (Ca (OH) 2 ) in the concrete and forms a gel which seals concrete surface pores, restricting moisture entry and exit. ASPHALT EXPANSION JOINT can be used in 80% of all control joint applications. Resists wash off from normal rain and dew once dried. Concrete Interlayer Bond Breaker Fabrics Home / Concrete Interlayer Bond Breaker Fabrics Historically, German engineers have been very successfully using non-woven geotextiles as interlayer bond breakers between lean concrete bases and concrete pavement surfaces for past 25 years.
