How Weather and Soil Conditions Affect the Installation of Metal Buildings

A prefabricated metal building can be a good option if you’re looking to complete your construction project quickly and cost-effectively. The key is to find a reliable and established fabricator — like Armstrong Steel — so you can be confident in your building’s durability, longevity, and structural integrity.

Pre-engineered metal buildings can speed up your project timeline because everything is faster and easier. For example, Armstrong Steel designs and engineers every component of your building in their facility, which means that your steel building kit arrives ready for assembly. This reduces on-site labor while minimizing construction time. Detailed assembly drawings, anchor bolt patterns, and erection guides simplify the construction process, too.

To ensure your metal building is optimized for your specific location, Armstrong Steel considers the local building codes, weather conditions, and load requirements in your area. Their experienced team will design a structure that meets all necessary standards while providing the durability and functionality you need.

Weather and soil conditions matter. 

Both traditional and metal buildings rely on a strong foundation to withstand the local climate and soil conditions. This is why the location of your building site plays a crucial role in the long-term performance of your steel building.

Different soils come with specific challenges. For instance, loose sand may erode easily over time, while dense clay will tend to shift. Additionally, weather can impact metal building designs, influencing choices in roofing material, insulation, and more. Understanding these factors can help you build your project successfully.

This blog shares a more in-depth look at how weather and soil conditions can impact the installation of steel structures. Read on to explore various soil types and discover the most suitable foundation for your metal buildings.

Different soil types and their suitability for steel building foundations

Different soil types have varying characteristics that can either support or hinder the construction of a steel building foundation.

Clay soil

Clay soils are fine-grained and tend to stick together. However, they can expand and contract significantly with changes in moisture levels, which can put stress on foundations. This is why you may need a carefully engineered foundation to manage potential ground movement. These challenges can also impact the cost of your metal building.

Gravel and sand

These soils have less cohesive strength but excellent drainage, affecting the foundational load-bearing capacity. Being permeable, gravel and sand can help with moisture management. Over time, this reduces the costs and simplifies the foundation requirements of metal buildings.

Loam soils

Loam is a mixture of clay, sand, and silt in carefully balanced parts, offering sufficient stability and drainage to support steel buildings. Construction on loam soil is generally cost-effective, as it doesn’t require the extensive measures needed for more challenging soil types.

Rock and bedrock

These soils provide an incredibly stable foundation, making them ideal for a metal building that will bear heavy loads. However, be ready for high excavation costs. Despite the significant upfront digging costs, rock and bedrock soils offer long-lasting stability that makes them a cost-effective investment. Plus, they help reduce long-term maintenance.

Peat soils

Peat soil (which is composed of water-saturated organic matter) is highly unstable and prone to settling. This can create foundation issues for metal buildings. If you have no choice but to build on peat soil, be sure to use advanced foundation solutions such as reinforced concrete piles or raft foundations to prevent subsidence. While these solutions may increase initial costs, they are essential for long-term structural integrity.

Silt

Silt soil, while well-draining, has a similar particle size to clay, so it is prone to compaction and erosion. To build a stable steel building on silt soil, you need to carefully plan and design your foundation. Consider using reinforced concrete footings or a slab foundation to mitigate the risks associated with silt soil. You can also consult with a geotechnical engineer to assess the specific soil conditions and recommend the best foundation solution for your project.

Factors to consider when selecting a suitable foundation for your soil

Choosing the right foundation is important for durable and long-lasting metal buildings. Ultimately, your choice will be largely based on your construction site’s soil characteristics. Here is an overview of different foundation options and how they can work with various soil types.

Asphalt-based options

Asphalt foundations provide a durable and flexible option for stable soil environments. They distribute loads well and withstand temperature fluctuations effectively, making them cost-effective for steel buildings with moderate to heavy expected loads. Just be sure the soil conditions are ideal.

Natural soil

Does your site have stable and firm soils like compacted earth or rock? Native soil can be an economical and effective foundation that minimizes the need for too many materials. On the other hand, construction sites with shifting or expansive soils may need a more solid solution like pilings or reinforced concrete to provide optimum stability for your metal building.

Gravel Foundation

Known for excellent structural support and drainage capabilities, gravel foundations are perfect for loamy and sandy soils. They are rather easy and cost-effective to install, but remember that the material can shift and settle, which can be managed with regular upkeep.

Concrete foundation

Does your site have challenging soils like peat or clay? Concrete foundations ensure longevity and reliable support for metal buildings. But don’t let the high initial investment deter you. The low maintenance and strength of concrete foundations will offset that down the road, ensuring a long-term and dependable solution for your structure.

Understanding how weather can affect the foundation of steel buildings

Weather can impact the foundation of your metal building in addition to soil. Factors like drastic temperature fluctuations, heavy rainfall, and high winds require careful consideration, as these can degrade the foundation’s integrity with time. If you’re not careful, your foundation can develop weak spots, cracks, and other structural failures.

Temperature changes and how to deal with them

Dramatic temperature changes can be challenging. In warm climates, soil contracts and makes the foundation settle, negatively impacting the stability of metal buildings. On the other hand, frost heave in cold climates can make the soil expand due to freezing water, causing the foundation to shift.

Heavy rainfall

Heavy rains can impact the foundation of your metal building when the soil becomes saturated. This results in instability and erosion, ultimately causing the soil to settle. If you’re in a flood-prone zone, make sure your foundation can manage water effectively to prevent damage.

High winds and structural stability

Soil erosion is common in windy regions, thanks to the constant vibration and pressure of strong winds. The best way to mitigate that is by designing a foundation that can withstand high winds. This will help ensure the long-term structural integrity of metal buildings.

How to choose an appropriate foundation for steel buildings

Various factors can impact your choice of foundation for your metal building. Take the time to review these important considerations to make an informed choice:

Characteristics of the land

It’s crucial to analyze and understand your property’s soil type, drainage, and landscape when choosing an appropriate foundation for steel buildings. A professional soil test can show the soil’s stability and load-bearing capabilities to help you pick the right foundation.

Your structure’s purpose and type

The size and function of metal buildings can significantly impact the type of foundation necessary to support them. A basic soil foundation may be enough for a small steel shed, but a larger prefabricated industrial or commercial building needs stronger concrete foundations to support its heavy loads.

Weather conditions

Expert steel building fabricators like Armstrong Steel consider your local climate when engineering a metal building. Factors like rainfall, temperature changes, and extreme weather events can impact the foundation’s reliability and soil characteristics over time.

Wind speeds

Are high winds common in your building area? You need a foundation that can stand up to powerful lateral forces. This could mean using sophisticated anchoring systems or a deeper foundation to reinforce structural stability for metal buildings.

Load capacity requirements

It’s crucial to understand and assess your building’s expected loads, such as special structural features, stored equipment, and heavy machinery. With this knowledge, you can pick an appropriate foundation that can optimize and support the safety and functionality of your metal building while preventing problems down the road.

Foundation Drawings

Foundation drawings are critical blueprints that detail the precise specifications for a metal building’s base. However, creating these drawings without comprehensive on-site verification can be both costly and detrimental to your project’s success. While a foundation drawing might appear technically sound in a design office, the reality of actual site conditions can render such generic plans ineffective or even dangerous. Soil characteristics, local weather patterns, wind speeds, and specific load requirements demand meticulous, site-specific engineering. A foundation drawing that hasn’t been tailored to the unique geological and environmental conditions of your specific location can lead to significant structural challenges, including foundation settling, erosion, instability, and potential catastrophic failure. Reputable steel building manufacturers understand that foundation drawings are not a one-size-fits-all solution, but rather a carefully crafted document that must reflect the precise characteristics of the construction site. Skipping professional soil testing, wind load assessments, and detailed site evaluations can transform what appears to be a cost-saving measure into a potentially ruinous financial burden.
