Concrete Footing Cost: 2024 Footing Cost Per Linear Foot
Table Of Content
Without a foundation, a home might start sinking into the ground or be damaged by accumulated rainwater, sleet, ice, insects, rodents, or other pests. Concrete walls, on the other hand, can be reinforced with steel to spanopenings. That means the footings can be discontinuous, jumping from the 4-footto the 8-foot or 9-foot elevation. Spanning Over a Soft Spot Some sites have occasional soft spots in otherwise good soil.
C. Safety Considerations During Footing Construction
The lower the square footage of your home, the cheaper your foundation may be. You can expect to spend anywhere from $4 to $7 per square foot on a concrete foundation. If there is rock below your build site, for example, you might need a structural engineer to examine the lot and figure out a plan for building over it. In other cases, unstable soil could mean you need to select a different build site.

The bulging sides of the finished footings also help to divert water away from the foundation. Considerations include the depth of the frost line in the region, water tables, flood zones, the type and stability of soil, as well as slope and drainage of the site. Wide regional differences in foundations can be explained by climate. In New England, most homes have basements, while warmer locations in the South are likely to have crawl spaces or slab foundations. The cost of concrete footings can vary depending on factors such as size, location, and materials. Planning your budget carefully and getting multiple quotes from contractors can help you manage the costs effectively.
Planning and Design
For example, if I need to step the footing down 4 ft., I would slope the bottom of my footing 8 ft. horizontally. Poor soil condition is one of the most common causes of footing failure. Neglecting to remove the topsoil is one possible reason for this. Topsoil can contain a large amount of root structures and other organic materials, resulting in a low load-bearing capacity. If the excavator digs too deep and soil has to be added back to bring the surface up to the correct level, that newly added layer of soil needs to be properly compacted.
B. Stability and Support to Structures
Some soils are so poor that specialty footings/foundations are required. In these cases, a geotechnical engineer will test the soil and make recommendations for what type to use. Most local building officials will take into account the types of soil common in the area when reviewing plans during the permit plan review process. A footing, sometimes called a footer, is the part of a house that interfaces with the ground.

Weaker soil will need wider, more expensive footings to compensate for its reduced weight-bearing capacity. Before you pour footings, have the soil tested at your project site. Different types of soils have different load-bearing capabilities, so you’ll need to know the soil type to ensure you use the right strength and amount of materials. Concrete footings cost $1.50 to $24 per linear foot, averaging $5 per linear foot.
Keyways were once a standard method to make sure a foundation wall would not shift off a footing when backfilling, but all of my plans prescribe rebar to keep the walls in place. When a footing is an integral part of a floor slab, the walls above are often held down with anchor bolts that penetrate the footing. You can look up the recommended footing size, based on the size and type of house and the bearing capacity of the soil. As you can see, heavy houses on weak soil need footings 2 feet wide or more. But the lightest buildings on the strongest soil require footings as narrow as 7 or 8 inches.
They also provide a stronger and more stable foundation than other types of footings. Strip footings are also cost-effective since they require less material and labor than other footings. Strip footings are an important type of footing used in building construction. They are usually used to support walls and columns but can also be used to support other structural elements in a building.

Footing is a structural component situated at the base of the foundation, usually made of concrete. It extends below the frost line (the depth to which the ground freezes in winter) and is wider than the foundation wall or pier it supports. This width helps in distributing the load and provides stability against overturning and sliding forces.
Of course, you can choose whatever foundation you prefer, but costs—and engineering issues—can creep up, too. Disturbed soil can eventually be classified as undisturbed after enough time; a soil test can determine this. Emily Estep is a plant biologist and journalist who has worked for a variety of online news and media outlets, writing about and editing topics including environmental science and houseplants.
The primary function of footing in building construction is to distribute the load of the structure evenly to the ground. This process is crucial in preventing excessive stress on the soil and ensuring the building’s stability. Raft or mat footing involves a large concrete slab supporting the entire structure. It’s typically used when the load-bearing capacity of the soil is low.
Types of footing in building construction vary based on their design and the load they support. They range from simple isolated footings that support a single column to more complex raft footings for buildings with heavy loads. There are several types of footing in construction, each designed to meet specific structural and soil requirements.
Width of the wall meets the minimum footing requirements in the building code. Every house is built on a foundation, but not every house is built on the same foundation—some are stronger, while others are more affordable. Some materials are common, like concrete, while stone and wood were historically used in older homes. The home foundation type used is based on house design, geographical location and climate, soil and moisture conditions, and the project budget. A footing is a structural component found at the base of a building. Its primary purpose is to support the building’s foundation and distribute its weight evenly across the soil.
It might be a little less or a little more than the code assumes. Pile footings are an economical and reliable solution to a wide range of construction problems and are often used for foundations under bridges, buildings, and other large structures. They are an excellent choice for construction projects in areas with too weak soil to support other types of foundations or in areas where the water table is too high for a shallow foundation.
Typically, piers and footings are poured on separate days to allow time for the concrete to cure. Now Tom does it in one shot using funnel-shaped plastic footing forms fitted with cylindrical pier forms. “As far as I’m concerned, there’s no better way to make a concrete pier,” he says.
Elevated slab foundations are one innovative solution to flood issues. Your local climate can also influence what type of foundation is best. If you live in an area where the ground frequently freezes and melts, you could see cracks in your home’s monolith slab foundation.
