What is the Best Depth for a Footing?

Footing depth can be confused with the thickness of a footing. Eight inches is the minimum thickness for a footing. Ten inches is better and twelve inches is highly desirable.

The depth of the footing in the ground depends on:

  • the local frost depth
  • how deep you need to go to be in solid strong soil

What Type of Steel Should be in the Footing?

You should put two continuous steel rods in the footing. The diameter should be no less than 1/2 inch. When you get to the end of one rod, overlap the next rod onto the first one at least 16 inches. Use baling wire to tie the two pieces of steel together.

The black lines are the footing. The red dots are the continuous steel rods. This is a cross section of a typical footing. Make sure you order the concrete at least 3,000 PSI. Questions? I can call you on the phone if you like. CLICK HERE to have me call you up.
