Concrete post footing and general post guidelines.
I thought it would be wise to post my plans for my deck posts to get any suggestions. Please let me known if anything I'm doing is overkill or insufficient. I live in Central Texas.
I plan to dig a 2' 2" down. The 2" is for gravel. The 2' is for concrete.
I wanted to use the forms from Quikrete (http://www.quikrete.com/ProductLines/QuikTubeBuildingForm.asp) but the VA code doc says my footings should be 18" in diameter but the Quikrete forms come in 12" diameter at most. What should the diameter of my footings be?
I plan to let the forms come out above the ground 2".
Quikrete recommends that I use
QUIKRETE 5000 Concrete Mix (http://www.quikrete.com/ProductLines/Quikrete5000ConcreteMix.asp). How many bags will I need per footing?
Once the concrete cures I plan to drill holes for wedge anchors. I'll use 1/2" x 3" wedge anchors. Then I'll attach Simpson ABA44 post bases (http://www.strongtie.com/products/connectors/AB-ABA-ABE-ABU.asp).
I'll use pressure treated 4x4s for my posts. They will be about 22" high. I read somewhere that this may be short enough to cause the posts to crack... I don't know that I have a choice.
I'll attach the posts to the beams using Simpson BSC2-2/4Z (
Again, any comments welcome.
