Do they make a staple to join a concrete crack that is between two pieces of concrete on a slab?

Question

I have a 1/16" crack about 4-5 feet long below my concrete floor located in my dining room. I noticed the cracks as my floor tiles started having the same size crack in them as well. What is the best way to fill those cracks in? With what products? My goal is to fix those cracks and then put the new floor tile back down and cover the repair. By the way the crack are not leaking any water..

Or what would be the best type of fastener to use to join the concrete and prevent it form spreading apart further?

Answer 1

They make a product that you glue down with a vitreous tar like substance that smells like brake cleaner. Use good ventilation!!! AFM, anti fracture membrane, is available at most tile retail and whole sale stores. It works by allowing movement of up to 1/8th of an inch in the substrate or slab with out transferring that movement to the tile on the top. I have used it for similar problems with great results.
The crack in the slab means that either part of the slab has moved or the support under the slab has settled and allowed it to move. First make sure the slab is stable and not going to get worse. Nothing like getting to do the tile 2 or 3 times to gain proficiency, but better to do it right the 1st time. You might check in with servicemagic.com for a professional in your area. They screen the contractors they use and require them to be reputable as well as hold the required license and insurance. If you feel like doing the slab work yourself you will need, a way to remove part of the slab, preferably a wet saw. masonry drill bits and rebar to reinforce the area you remove. and of course a good quality high strength cement to replace it with. AT least 3000 psi, you can buy additives that help the concrete cure if you can not find something in a bag at the hardware shop.

Answer 2

Maybe slab jacking would push concrete up and into the cracks and fill the voids that are stressing the slab. An idea that could have merit.

Answer 3

home depot or Lowe's has products for cracks in concrete floors.
if none of these are available in your area check with your local hardware store
