The importance of footing in building construction cannot be overstated, as it lays the groundwork for the entire structure’s stability and durability. Drilled shafts or caissons are similar to pile foundations but are constructed by drilling large holes into the ground and filling them with concrete. They are used in structures that require a deep foundation due to unstable soil conditions. Footing in construction can be classified into various types, each designed to address specific structural needs and ground conditions. The five main types of footing include strip footing, spread footing, raft or mat footing, pile foundation, and drilled shafts or caissons.

Foundation Facts

The idea is that the thicker edge bears the weight of the exterior walls, just as a separately poured concrete footing would. Frost-protected shallow foundations and raft slabs are similar, but rigid insulation is used to prevent frost from getting underneath the slab. Most formed footings for a typical home in New England that I design are somewhere in the range of 16 to 24 in. This will vary based on the loads imposed on the footing as well as soil conditions.

Attach string or twine to the corner stakes (or batter boards, if using them) and run it along the outer edges where the foundation footings will be. Add temporary bracing to the stakes to keep the layout secure during excavation. Moreover, obtaining the necessary permits and adhering to local regulations is essential.

IRC requirements also take into consideration the soil type that footings are built on. The IRC recognizes five different types of soil, ranging from solid bedrock, with a load-bearing capacity of 12,000 lb. The less weight a particular soil type can support, the wider a footing needs to be.

Because concrete is very poor at resisting these tension forces, steel reinforcement bar, or rebar, is added for strength. The IRC has tables for the minimum rebar requirements for different situations. The most common sizes in residential construction are #4 and #5 rebar, typically with two continuous lengths located toward the bottom of the footing.

The most common applications of strip footings are for foundation walls, exterior walls, interior walls, columns, and pillars. Strip footings can be used to construct residential, commercial, and industrial buildings. The advantages of using shallow footings include their affordability and ease of installation. They can also be used in various soil types, making them versatile for different building structures. Additionally, shallow footings don't require much excavation work, making them a much faster and less intrusive installation. When construction workers pour a slab on grade — aka, a monolithic slab — they complete the pour in one go.

This is important for keeping moisture coming from the soil off the slab. You’ll want to cut channels into the vapor barrier and fill them with a grid pattern of rebar and concrete to add stiffness to the slab. While all the elements of the house should be very well connected, the foundation shouldn’t be as connected to the ground and the house should be able to move independently of the ground.

Additionally, the materials used to create pile footings are susceptible to corrosion and damage and must be properly maintained. By far the most common type of foundation for difficult terrain is a concrete slab. The first step is to reinforce the soil with a stiff slab and cover this with tough and durable plastic wrap; this layer acts as a vapor barrier for the house. An elevated slab foundation, like Tella Firma’s, combines a slab foundation with a pier-and-beam system. The elevated foundation takes a little longer to build and is more expensive than standard foundations—but it can save you money if water damage is a concern.

I know of cases where poor soils were detected and a geotechnical report for the site was completed, but that information was never shared with the structural engineer. There is wide agreement that creating a path for water to 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 of a poured footing. After the footings are constructed, the area inside the footings is filled with a drainable gravel such as crushed stone.

These innovations aim to enhance efficiency, accuracy, and safety in construction processes. Pile foundations are deep foundations where long, slender columns are driven deep into the ground or constructed in place to transfer the load to deeper, more stable soil layers. In simple terms, all footings are part of a foundation, but not all foundation components are footings. The footing is like the feet of the foundation, providing a stable base for the rest of the structure. A foundation is the base of a home that supports the main structure while protecting against moisture, frost heaves, pests, and more.

Employ the triangle method to ensure the foundation corners are square. Measure 3 feet along one string from a corner stake and 4 feet along the adjacent string. Our guide offers a step-by-step overview of how to lay a foundation and insight into do-it-yourself (DIY) options. However, in nearly every scenario, we recommend hiring a professional to ensure safety, quality, and peace of mind. Remember, foundations are complex structural elements that leave little room for error.
