    Whenever we see cracked floors inside a building and the footer is good.... the usual culprit is BAD compaction/inappropriate fill under the slab.... and we see it a lot near the edges... mainly because people didn't/couldn't compact close enough to the footing....

    Sorry for the thread hijack but you know that Drummond are also in Colombia..?
    Walker & Winston counties were dry in those days. You had to go down Hwy78 to the Green Top on the Jefferson County line to get beer.
    According to the Costeños from the Atlantico Province in Colombia where the Drummond mines are located there are two type of gringos - "Gringos" and "Alabama Gringos"

    Id go with poor compaction and skimpy rebar, the crack was there waiting to be exposed. Demo and patch would prove the weakness, but epoxy injection would be the quick fix to that crack. It just would nt reveal the cause of the crack. In years of doing pile driving jobs there were a few complaints especially if we were in clay. Got the point where my insurance co wanted a pre blast survey as they called it. Never created any real damage ,people just like to bitch. Bear in mind these werent big piles,maybe up to 20000 ft lbs energy, but you can feel it.

    Small world isn't it! I wasn't around 40 years ago though. I grew up riding my dirt bike in the strip jobs around the Jefferson and Clearfield counties. They have made the access into and out of the DuBois airport much better within the last 10 years. I swear Barney Fife runs the security at that airport though.

    HA! Winston county is still dry...Walker is not. Winston County stills calls itself the Free State of Winston. During the civil war they never picked a side - story has it they were selling moonshine to the North and South and didn't want to upset their customer base.o_O

    A friend of mine from High School works for Drummond and regularly goes to Columbia. The pics of their mines down there are impressive.

    So, what is the complainant wanting from you.
    Is the crack tight, or did the piece separate slightly ?
    Did you put a level on it to determine if the triangular piece heaved any ?
    A core drill sample containing both sides of the crack would be interesting to see if the crack is fresh.

    Considering the vibration caused by them, it doesn't surprise me someone who's foundation is 2' away from where one was working is complaining. I have been 100' away from one on a 200 hoe and you can still feel the ground shaking. I personally wouldn't be running one within 20' of any foundation without someone signing off on all liability to any foundation damage caused. It's not always whether you caused damage, it's whether or not someone will try and come after you claiming you did. I bet on 20% of demos I do I get a neighbor complaining dropping pieces of concrete to break them was shaking their house and thinking it caused damage even if the house is 20-30' away.

    A basement floor cracking in a corner like a triangle is nothing new. But really hard to prove either way when it happened.
