Not only does TEC HydraFlex exceed both ANSI crack isolation and waterproofing specifications, it is the only liquid applied, crack isolation membrane that can bridge saw cut/control joints. However, only one liquid-applied membrane can bridge saw cut / control joints: TEC HydraFlex. Most Division 09 30 00 tile setting specifications list crack isolation and/or waterproofing membranes that can meet ANSI A118.12 specifications for crack isolation and ANSI A118.10 for waterproofing. TEC ® HydraFlex ™ Waterproofing / Crack Isolation Membrane is the solution. What do you do, as a contractor or specifier? Unfortunately, many installation guidelines for crack isolation membranes result in numerous cuts in the middle of the tiles that can detract from the overall aesthetics of the floor. One of the pains of specifying and installing tile over concrete is figuring out the proper way to keep tile intact despite substrate cracking due to shrinkage.
It’s when it cracks and if your tile is bonded to the cracking concrete, what happens? That will crack too.
