Stone Veneer Wall Quesiton 2

[txinspector]

I have a municipal inspector in North Texas contending that a single-family residential foundation edge (brick ledge) will not suffice for the stone intended. This is a structurally supported (piered) post-tensioned slab. The stone is medium-density limestone weighing 150 lbs. per cubic foot. The stone units are an average of 5 inches thick. The tallest wall is 20 ft. in height. He contends that the weight of the stone will exceed what is allowed in IRC Table 703.8(1).

Is he right?

Well as the engineer you simply can calculate the capacity of the concrete ledge for bearing.
If the depth of concrete below the ledge is minimal, and it's acting more like a corbel, then a check of the corbel capacity would verify the case.

Assuming you are an engineer and know how to do this...if the design exceeds the IRC then an engineer can simply verify it and provide the municipal inspector with the proof...and a signed/sealed document stating such.

Thanks.

Note that there are also tighter deflection limits sometimes when supporting veneer for PT slabs.
