Concrete slab cracks in Florida

Hey guys, I hope someone can give me an opinion about this cracks I’ve found in a monolitic concrate slab in a house on construction at SW Florida. They look common cracks to me (shrinkage/settlement) They’re not wider than 1/8". And they go accross the slab from one side of the house to the other. Most of them are going in the same direction at diferent points, specially on the thinner sections of the slab and at the plumbing penetrations. I will apreciate your help. Here are some photos.

Daniel,

Are you sure that is a Mono. SOG ? Looks maybe supported?
What is the CMU wall in Pic.2?
How old is the pour ? What were the environmental conditions (Temp., Moisture conditions, etc.)?
Do we know if the area has compacted soils, vapor barrier, wire, etc.?
Don’t know the rules (specific in FL.) but these are typical questions I ask.
Can you enlarge the Pic’s., cause I can’t. Hard to see what you see.

Good Luck

Daniel,

Looks like too much water was added to the concrete when it was poured. It should not be cracking like that, espeically with the control joints.

The control joints may not be deep enough.
Overall not a big deal.

I’m agree with you guys. It shouldn’t be craking like that (at least not that many cracks in such a short time) My concern is if it represents a further foundation problem. I guess is hard to tell at this point.

Could be a whole host of problems. Did you get to see the set up before they made the pour. Many times the screen / mesh is not installed right.

William unfortunately I don’t know how well was the site prepared for the concrete pour. Like you said, is hard to be especific on what’s cousing this. and for me is hard to tell if this represents a problem in the future.
