Here's the problem.

"I guess it has started to come up a little bit more," says Don Purvis.

"Cracking, all the way into my entrance into my house," says Elodio Cervantes.

"My front patio with my porch you can see it, it gets really bad here," says Teri Blevins.

"See how it's cracking," says Cervantes.

"You can see where it's really bad, it crumbles, as you touch it," says Blevins.

"Yeah, there's definitely problems," says Bryan Landon, owner, Byran Landon Construction..

"That's obvious, but the cause of it, who knows," says Ryan Murdoch, Byran Landon Construction.

One view writes: "If concrete is fresh and is not sealed after it is poured and finished, then flaking can occur."

First of all, sealer is used to protect concrete from the weather and other elements.

"But essentially its good to seal concrete yes, but if you sell it too early as far as your finishing procedures then it can create a problem," says Landon.

Another writes: "If the concrete is poured too wet."

"Basically, the water and the cement is like glue, you want to have the correct balance, you don't want to have too little or too much," says Landon.

Then there is this factor: "If the finisher overworked the surface or finished the slab improperly, then that slab froze before the proper curing could take place."

"Yeah you don't want to overwork a slab, if you have to add water or something on the top because you're loosing it or you can't keep up with it, that's a problem, also if it freezes before it curred, there's water in the cement which expands and breaks up the concrete," says Landon.

Over worked concrete means it's getting too hard too fast.

"And you have to overwork it to get that desired texture that you're looking for, and sometimes in doing that you will cause a concrete to fail or delaminate," says Landon.

Another viewer writes: "The wrong mix design was used."

"There's sand, there's all different sizes of rock and mixtures that go with that, and that makes for a good well graded mix," says Landon.

Then there's the factors like ice melt or rock salt on their driveways.
One email reads : "People should wait two to five years before using those products."

"I would recommend people not use the ice melts , if they do give that concrete a complete year to cure and dry. The main thing is people need to keep their driveways clean, shoveled off. If they keep it clean, then the freeze thaw cycles aren't as hard on the concrete," says Ryan Murdoch, job supervisor.

Ice melt and concrete can create a chemical reaction.

Lots of reasons can play a factor as to why those driveways turned out the way they did. Like what the weather or climate conditions were that day, the concrete got poured, the amount of water and mix design. There are still lots of issues that can be addressed. The best way to know exactly what the problem is would be to take a core sample and test it out.
