What are Concrete Footers?

Written By Kenneth Wilson  |  3 Comments

Concrete footings are usually required for new aluminum construction.  A concrete footing is a section of concrete thicker than a typical concrete slab reinforced with steel.  The depth and width of a footer as well as the amount of overlapping steel rebar makes this a very labor intensive part of screen enclosure or aluminum roof construction.  Footers must also be inspected by the county or city before they can be poured as part of the permit inspection process adding fees and time to your project.  Footers come in many sizes can require different amounts of steel, all of which will be determined by the engineer for your unique project.  The main considerations that go into footer size are soil quality, size of enclosure and uplift factor.  Without a footing your enclosure or roof could rip up your concrete and blow away slamming into your house or your neighbors.

  • Continuous Footer with Monolithic slab: A footing around the end of concrete slab.  These are most common for a screen enclosure.   A common size for a continuous aluminum construction footer is 8”x8” with overlapping #5 rebar.


  • Ribbon Footer: Also a continuous footing but without a slab.  These are used web pavers, or other stone will be used as the flooring material.  They can can also be done, for a landscaped area to be included within the enclosure.


  • Isolated Footers:  a ‘big chunk’ of concrete used to anchor a post.  They are usually 2’x2’ or 3’x’3 and are commonly used for carports or utility covers.

About the Author

I can build it, and I can help you get the patio enclosure you want! I got my start in the Florida patio industry back in the 70s as a young general laborer looking for something to make a few bucks. At the time I never thought it would end up as my career. Over the years I grew beyond the laborer position, becoming a foreman, superintendent, and then into executive management for some of the largest patio contractors, and material vendors. Now into retirement and slightly bored, I offer consulting services to new and existing contractors, and publish this website to help the people who love their patio's and screen enclosures the most - YOU!
