The old saying: “You can’t build a great building on a weak foundation,” is usually a philosophical consideration relating to personal character, but the same applies to commercial steel buildings. Solid building foundations pave the way for a successful, reliable and durable steel installation that can withstand the test of time.
A robust foundation protects your steel build for the long haul, ensuring less vulnerability from harsh weather conditions, dampness and subsidence. It’s one of the most integral components of any commercial steel project.
When it comes to building foundations, there are many options to choose from. Because of this, the prospect of selecting a building foundation might feel a little overwhelming, but our expert team are always on hand to offer their expertise.
In this guide, we’ll explore the versatile world of steel building foundations and unpack why they’re so important for achieving a successful build.
Types of Foundation for Commercial Steel Builds
Since no two steel projects are the same, the building foundation type will depend on the specific site and project scope. Once our engineers and architects have conducted a detailed site survey, they’ll advise on the best foundation for the project requirements.
When it comes to steel projects, there are three primary foundation options: pad foundations, strip foundations and piled foundations.
Let’s delve into each in greater detail below.
Pad Foundations
This solution is often favoured for spaces that require porous floors rather than concrete ones. They are an ideal option for equestrian centres, agricultural buildings, barns and partially open-air structures like pavilions.
For pad foundations, square holes are dug in the existing ground and filled with mass concrete, creating a cube of concrete. The column leg is then bolted down to the cube, which forms the foundation. Cube sizes will depend on ground type and steel frame size.
Strip Foundations
Strip foundations are sometimes required to run between pad foundations, connecting them around the perimeter of the building. These foundation strips will be engineered depending on soil type and load requirements. They are often in place for perimeter walls to be built up from below ground level.
Piled Foundations
Piling is used when ground conditions are poor or when building loadings are great. A pile foundation extends deep into the ground; they are often drilled holes, back filled with mass concrete and reinforcing steel. The tops of the piles are often connected to pile caps and strip foundations, again using reinforced steel and concrete.
Factors to Consider When Choosing Your Building Foundation
When civil engineers decide on the type of building foundation needed for the project, they need to consider many factors, including:
- Soil type and quality
- Loading capabilities of the structure and the weight of all vehicles and machines
- Natural elements (including wind levels, earthquake potential, rain and snow)
- Local frost lines
- Building dimensions.
The Importance of Solid Buildings Foundations
Solid foundations are critical for any commercial or industrial steel build for the following reasons.
- Allows for even weight distribution and prevents the risk of overloading
- Keeps the building protected against moisture and pests
- Provides great stability and prevents any sinking.
Our expert team will analyse your site and decide what foundation type will best suit the soil and environment. They will also determine the best reinforcing options and the necessary curing time for the foundation to set.
