I'm not to sure about that. I'd give them a call tomorrow and ask and see. You will probably have to ask for the builder's section. Sorry to not being able to help you very much. PS. You would think that WOW 80 lbs. I will have enough to put up 10 decking post's (4"x4") but that would be enough for like 1 1/2 post's. I'm not a builder but I poured a 3' x 3' landing and it took about 8-10 bags and all the rocks, bricks & anything for filler that I could find!!!!
