Issue: Best alternative for deck post footings.
Replacing existing deck with new.
Existing post supports sitting on 4" poured concrete patio using Simpson stand off post bases.
Deck floor is 5' high.
California location, in no freeze zone.
New deck: 28'x 16'.
13 posts are to be 6', 12' and 16' from house, 8' on center.
Three alternatives being considered.
1. Continue to use Simpson stand off post bases on the 4" poured concrete patio. Existing deck has had no settlement or movement issues.
2. Use concrete saw to cut 8" openings in patio for 24" depth concrete tubes with Simpson post or column bases. Cutting 13 holes in 4" concrete seems labor intensive.
3. Given the 4" thickness of the patio, use a jackhammer to create holes for 8" footings. The jackhammer approach would create a rougher opening and some risk of cracking surrounding concrete.
If you have experience with this type issue, what's your best thinking?
Thanks!
