The International Residential Code (IRC) defines minimum requirements for footing sizes based on the weight of a structure as determined by its size and construction type, as well as the amount of snow common to the area. The heavier the house, the larger the footing needs to be. IRC requirements also take into consideration the soil typethat footi...
During the plan-reviewstep in the process to obtain a building permit, your local building official will check to see that the footings you are proposing meet the IRC minimum-size requirements based on the weight of the structure above and the soil type you plan to build on, and if you have a suitable water-management plan. The official will also w...
Concrete has tremendous compression strength and can withstand an amazing amount of weight if the pressure from that weight is distributed evenly. However, its tensile strength is very poor, meaning that it’s brittle and subject to breaking under tension. Tension on a footing can be caused by conditions such as the heavy weight of a brick chimney c...
There is wide agreement that creating a path for waterto escape from beneath a building’s envelope is a good idea. A typical residence may have a perimeter drain located at the footing elevation. In a case where a house is being built on a site with saturated soils, the footprint of the house is cleared on the site to a level even with the bottom o...
Formed concrete footings are most commonly made with wood planks, although metal forms are sometimes used, and foam forms are also available. A common method when using formed footings is to excavate down to the level of the bottom of the footings. The forms are cut, assembled, and staked in place on top of the excavated pad. Crushed stone or struc...
Fabric-formed footings are built in a similar manner to wood-formed footings except that instead of using wide planks to form the concrete footings, 2×4 lumber is used to create a top rail, which supports the sides of a length of fabric. The fabric is draped between the rails and holds the concrete in place. The only fabric-formed footings on the m...
In this case, the footing and the wall are the same. To reduce the amount of forming wood required, these types of footings are often built so that the lower portion is in a trench. PROS: This is one of the fastest ways to build an entire foundation and can make sense for smaller projects like porches or additions, when one concrete truck can finis...
Building a trench footing is as simple as scraping off the topsoil, digging a trench, adding rebar, and filling the trench with concrete. PROS: Because they require so little labor, trench footings can be created fast and are less expensive than formed footings. CONS: Some jurisdictions don’t allow this type of footing. It is more difficult to mana...
Nobody ever said that a footing has to be made of concrete. The IRC does have a provision for wood-framed foundations on gravel footings, but I have never prescribed this method and don’t feel comfortable in doing so because even treated wood can deteriorate, especially if it is not properly protected before backfilling. A more common use for grave...
Pier footings are typically designed to support some type of beam system. Homes with pier-and-beam foundationsare most commonly found in southern states, but pier footings are the most popular method of supporting decks and porches throughout the United States. The beams on pier-and-beam foundations can either be made of wood and be suspended off t...
Aug 25, 2023 · A footing is a relatively small piece of concrete that’s set deep into the ground to distribute the load from the foundation to stable soil. Footings can serve as a small type of foundation on their own but are more often part of a larger foundation.

Dec 19, 2022 · Isolated footings, also known as spread or pad footings, are the simplest and most common type of foundation. Each footing supports its column that it takes the load from and spreads it to the soil it’s bearing on.
Footings are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench. The purpose of footings is to support the foundation and prevent settling.
Individual footing or an isolated footing is the most common type of foundation used for building construction. This foundation is constructed for a single column and also called a pad foundation. The shape of individual footing is square or rectangle and is used when loads from the structure is carried by the columns.
