Help with footings for large free standing deck
I am building (designing) a free standing deck 34' across x 16' out from the back of the house - 20" high from ground level to surface of deck (at door level).
Using (2)2x8 beams and 2x8 joists, with a cantilever of 12" for beams and 18" for joists all around, beams parallel to the house, and assuming a soil bearing capacity of 2,000 psf, in Brampton ON, what would be the best layout and size for the concrete piers?
Thanks in advance!!!
