I am installing 6” paver tile over a 8’ x 14’ concrete slab that has a diagonal crack, approx. 1/16" wide. It expands and contracts slightly. Will hydro ban prevent crack from telegraphing through the tile?

Crack suppression must be applied a minimum of 3 times the width of the tile or stone being installed. The tile installed over the crack cannot be
in contact with the concrete. Follow TCNA Method F125 for the treatment of hairline cracks, shrinkage cracks, and saw cut or control joints.

As an alternative; Apply a liberal coat of HYDRO BAN liquid, 3 times the width of the tile over the crack using a paint roller or paint brush and immediately apply the 6” (150mm) wide Waterproofing/Anti-Fracture Fabric into the wet liquid over the crack. Press firmly with brush or roller to allow complete “bleed through” of liquid. Immediately apply another liberal coat of HYDRO BAN liquid over the fabric and allow to dry. When the first treatment has dried, apply a liberal coat of HYDRO BAN to over the first wide coat, using a paint roller or paint brush, and allow to dry. Treat closest joint to the crack, saw cut, or cold joint in the tile or stone installation with LATASIL.
