Re: Hole in foundation
Rick,
I doubt it. With post tension cables you have an anchor cast into the concrete where the cable and its retainer wedge clamp bind up in the tapered anchor (the wedge and anchor are tapered to match each other, forcing the clamp tighter and tighter onto the cable the more the cable pulls on it - think of Chinese finger cuffs we played with as a kid, you put a finger in each end and then try to pull them out, you can't, you need someone else to release the finger cuff for you) - anyway, the cable is coated with grease (supposed to be anyway) then a cap is installed into the anchor and over the end of the cable. Then the entire void in the cap is grouted with non-shrink grout.
The hole for the anchor and cap is probably 2" or so in diameter. When a cable breaks, it pushes the cap out with it, taking out the non-shrink grout plug (fill) with it.
Those look like drilled 1/2" or 3/4" holes.
I asked about the spacing as that might give us an idea of what they are for.
