    6 Common Types of Commercial Foundations You Must Know

    Published on

    In the fast-paced world of commercial buildings, a structure’s longevity and stability depend on how carefully its foundation is chosen and put into place. The entire structure is attached to the earth and structural integrity is ensured by the foundation, which acts as the base upon which it is resting.

    However, each project has its own site characteristics and architectural requirements that led to the development of several foundation types, designed to address particular difficulties.

    Thus, calling in the concrete specialists is necessary to select the foundation design that will not disappoint.

    This article will go over the fundamentals of a strong commercial foundation and highlight the six best types of building foundations that are most frequently used in commercial foundations Tauranga construction.

    So, let’s dive into it!

    Understanding the Basics of Commercial Foundations

    Before letting you know about the commercial foundation types, it is important to understand the basics. So, you can make an informed decision as per your building project.

    The primary function of foundations is to provide a level surface for the building to begin on. To prevent the building from tilting and to guarantee that no part of the underlying site is overloaded, foundations aid in distributing the weight of the construction uniformly throughout the space.

    Additionally, foundations act as anchors against structural displacement brought on by extreme weather or seismic activity. With an established foundation you may also experience stress from disturbances in the ground brought on by adjacent buildings.

    The following are the main components of a commercial foundation:

    • Reinforced concrete
    • Foundation Walls
    • Piles, Posts, and Beans

    6 Common Types of Commercial Foundations You Must Know

    Now that you have understood the basics of commercial foundations, it’s time to jump on the types and put them to use for the best project output. Here we go:

    1. Mat Foundation

    Mat are also referred to as rafts because these bases are typically shaped like a rectangle or circular. These slabs work best in locations with low soil load capacities because they equally distribute the weight of the structure throughout the site through columns on the top floors.

    In addition to protecting differential settlement—the moving, contracting, or expanding of the underlying soil—mat foundations enable basements to be added to commercial structures.

    2. Pile Foundation

    In pile foundations, the building load is supported by vertical columns, or piles, that are pushed into the earth. Wood, steel, or concrete are used to create piles.

    This works well in places with high water tables or deep, unstable soil. Through end-bearing piles that offer toe resistance and/or friction piles that transmit weight directly into the earth, these foundations offer structural resistance.

    3. Slab-On-Grade Foundation

    Concrete is typically poured directly into unearthed soil to create a single surface for building in this straightforward and affordable foundation design.

    There may be a floating version applied in areas that become cold enough to freeze and don’t come into touch with the icy ground. Slabs have a stronger defense against underlying flaws like mold, mildew, and vermin since they are made of one piece.

    4. Spot Footing Foundation

    A single point of contact, such as a post, pier, or beam between the foundation and the underlying earth, is supported by this design, which is popular in commercial buildings.

    Spot footings are similar to a set of miniature foundations since they are composed of reinforced concrete and rebar and can be used as often as the structure’s columns require.

    5. T-Shaped Foundation

    These foundations are extremely resistant to freezing because they are made of several concrete footings buried well below the frost zone.

    After that, walls are built on top of them that extend to the surface to provide additional support, and the slab is poured in between them, usually with a layer of wire mesh for reinforcement. T-shaped sites are advantageous for both tall commercial structures and freeze/thaw sites.

    6. Drilled-Shaft Foundation

    This deep cast-in-situ foundation design is commonly known as a Caisson foundation. It is intended to support exceptionally high structural capacities. It is achieved by using accurately computed shaft resistance or precisely calculated toe resistance.

    Drilled shaft foundations are capable of sinking to a depth of 100 meters and can employ both resistance metrics.


    While deciding on the commercial foundation type, it is crucial to remember that, depending on the particular site circumstances and structural requirements of a project, a combination of different foundation types may be used.

    Engineers and concrete specialists must also take local building laws and regulations into account when deciding on the right kind of foundation for a commercial construction project.
