The piers are approximately 22' deep, with 36" bell bottoms, and it was
basically the same clay to that depth, and no telling how much further
This was about 25 miles East of Austin. .5 miles to the West of Austin
you would hit rock by scuffling your boot real hard ...
Basically soil at depth is not necessarily subject to the same effects
of changes due to dry/wet years as at the surface, and/or even
transmitted to the surface to the same extent.
IOW, unless you're drilling for oil, you gotta stop somewhere. ;)
My house in Northern California was like that - 8' deep
because we were on a slope (near 45 degree). Code was 48".
My curtain walls were not strong foundation like those! Those
look great. I had 18 each 8' dug deep holes.
Good job there.
