Extending Existing Mat Slab
Extending Existing Mat Slab
(OP)
Hello folks,
Does anyone have any suggestions with extending an existing mat slab?
The mat slab is 15" deep with #5 @ 16" O.C. E.W. T&B, and I'm wondering if my initial impression of doweling #5X18" @ 16" O.C. T&B and continuing the reinforcing would be acceptable? There are no significant loads on this extended section.
Any recommendations on how I should detail the joint?
Thank you,
R

I detailed the doweling of 2 rows of #5 bars in a staggered formation to try to avoid inducing crack lines. I had those dowels fully develop in tension. The reason for the two rows was to resist any sort of localized settlement between the two slabs with the intent that they would serve as a pseudo-couple.
