How To Repair Travertine Tile Cracks
QUESTION
How to Fix Cracks In Travertine Floor Tile? We had travertine "tiles" installed by our general contractor this past summer during a consummate home remodel. Unfortunately, at that place are several long cracks in our floors throughout the house. After looking back at pictures during the remodel process, we noticed that these cracks are in the same spots as cracks in the foundation before laying the stone. The foundation is over 30 years sometime. We do see in the photos that a white, approximately 12 " membrane was laid over the cracks... our stone pieces, however are 16 ten twenty. Our contractor has stated that it'south a problem with the foundation and that he wants to wait a yr to see how everything moves and that he will come back and either replace a few pieces or fill up with an epoxy. Afterward some research I am seeing several things incorrect.
Answer
ANSWERS - If the crack is a structural scissure in the concrete slab, which is a scissure that has vertical displacement from 1 side of the crack to the other, then a crevice isolation membrane will not mitigate the potential damages from that crack moving. So it could be a structural crack.
Or, if the physical cleft is what they phone call an in-aeroplane shrinkage type of scissure (a crack that only moves horizontally) then a cleft isolation membrane can exist used to prevent that crack from telegraphing up through the tile assembly. The standards show that to isolate an in-plane crack, the crack isolation membrane must exist centered and applied over the crack at least 3 times the width of the tile being used. In add-on to that, there should exist motion joints (grout joints filled with an ASTM C920 sealant) installed in the tile joints, that run parallel to the crack, on the tile that is bridging the crack.
Chances are, the tile installer installed the xvi x 20 inch tile over the 12 inch broad crack isolation membrane. That ways that the tile bridging the crevice was partially bonded to the membrane so bonded directly to the concrete at the exterior edges of the tile. Thus when there is move in the concrete it transfers directly upwardly into the tile causing the crevice, and the crack isolation membrane isn't able to mitigate that motion and stress to prevent the crack from transferring up through the tile.
The only mode to prepare this problem is to remove the tiles. If it is a structural cleft, then you need a structural engineer to determine how best to remediate the crack in the concrete. If it is an in-airplane crack and so install a crack isolation membrane under the entire space where the tile will be installed, and install the new tile over it. Then install one or two movement joints as recommended by the crevice isolation membrane manufacturer. Good Luck.
