Tips
There are two ways to keep water out of your trench. One is to have a large roof overhang and make sure the ground slopes down and away from the building at all points. The other is to lay perforated drain pipe throughout the bottom of the trench, making sure it's sloped and it all ultimately drains to daylight.

Introduction
Dig and pour your deck footings so they extend below the frost line. That way, they won't move, or heave, as the ground freezes and thaws during seasonal changes. This article explains how to build solid footings that will stay put year-round.
How Deep is the Frost Line?
If your setting deck posts move up in the spring then settle back down as the weather warms, then you have a bad case of “frost heave-osis.” So how deep is the frost line? In the winter, the ground freezes from the top of the soil downward.
How to get a solid, frost-proof footing
When you pour concrete footings, hold the cardboard concrete form tube about 12 in. up from the bottom of the footing. 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. Then dump concrete through the tube into the bottom of the hole.
Ordering Premixed Concrete
If you're pouring more than a few footings, order premixed concrete from a ready-mix company. You'd be shocked at how many bags of concrete mix you'd have to mix by hand to fill a form tube.
