It s hard to imagine an easier deck footing option than deck footing pads.
Foam instead of concrete for deck footings.

Effectively replaces two 50 lb.
Bags of concrete mix.
Do this by nailing the sides of the tube to the center of a tic tac toe grid of 2x4s at the top of the hole.

Editors comments yes you can use the new foam that is available to stabilize support posts.
The idea is simple.
It is mixed in the bag to produce expanding foam for supporting and backfilling fence mail box gate and signage posts.
Can be used with wood steel and pvc posts.
No hauling cement bags no mixing no messy pouring no waiting for cement footings to dry.
