Does anyone have any info on using packed
clean gravel as a deck foundation instead
of concrete piers? I've been told that Basically you dig a hole below the frost line and instead of using concrete, you fill the hole with clean 1b gravel and set the deck posts directly on the gravel. Has anyone heard of this before?

Thanks,

Harry

It should work, but why waste all that expensive treated lumber. Think about concrete deck piers. They look like pyramids, and are notched in the top for your deck support posts. Very inexpensive, and easy to use. They sit on top of the ground. They work everytime. Good Luck

Harry, I agree with Jack's post, to a point. But depending on where you live, and how severe of an issue frost may be, I would dig a small (14 to 18" diameter, 6 to 12" deep) hole where each pier block is going to be, and fill it with concrete, then set the pier blocks in the wet concrete. This is probably what your local bldg. dept. would require.
