Cracked slab floor
We received a call from a homeowner about a row of cracked tiles in their bathroom floor. The cracked tiles were due to a slab crack directly under the tiles.
When re-setting tile over a crack like this its important to use a flexible setting material. Most membrane or elastic-type setting products will work over slab cracks moving sideways, but will not discourage cracking with up and down movement. This is the product we use and recommend when setting over slab cracks: Elasto Pro EP200
Its been almost a year since this repair job was completed and the homeowner reports that the replacement tile hasn’t had any problems!
