jeep jake said:thats killer!!! the footings are pretty big what was the PSF of the soil? I'am surprised there was no soil bracing. Why did you go with CMU?
Solid clay ground no need for bracing. Their is a 15-20metre drop at bottom
Of our garden which jcb dug which has no support or anything just cliff face clay.
Their use to be a building already in its place with single 100mm block wall no steel or concrete and been there for. 20years or so I wasn't worried about it caving in on me.
Their is steel inside the blocks 12mm bars, gotta tie some more to them though just bellow block line do that before infill with concrete.
Their is also horizontal steel bars on every course but that was my idea as its not been specified on the structural engineers drawing to have horizontal bars on every course.
Footings spec was c40 concrete with all that steel and its 900mm deep in the toe and 500mm deep in the heal 2metre wide that's strong enough to build a multi storage car park lol. Then just a simple hollow blocks wall with concrete from one extreme to another lol.
