repair to monolithic slab
(OP)
a local contractor poured a monolithic slab radient heat slab over compacted sand(30 x 36)for a private garage. the problem is that the slab is 14" out of square,the building official issued a stop work order untill this is corrected .
the contractor obtained the services of a PE who dictated saw cutting across the slab than drilling holes embedding # 4 bar 10" ( 20db) deep at 1 foot on centers than reforming this new section to be poured -doing so would provide a even exposure along this line in question.
the contractor only drilled in 2 " so as not to damage the pex radient tubing.
another stop work order was issued
the PE has since stated that 2 " of imbeddment is sufficient.
anyone have any thoughts --- is 2 " sufficient?

10" seems very deep to start with, which makes me think that an epoxy may not have been specified. Is that the case?

Second, without consulting any literature, my initial gut feel that 2 inch embedment does not sound enough (only my gut feel).
Third, I also think that 10 inch embedment is excessive. I think 4 to 6 inches would be sufficient.
Fourth, I would ask the engineer to substantiate the 2 inch embedment.

1/2" rebar
Min. embed (published values) = 2"
