Why Are Deep Foundations Important

When contractors want to transfer building loads further down the earth to utilize the more stable soil, then deep foundations are the most effective solutions for this vital process. It is common to conduct a thorough assessment of the site and find that the soil is not stable enough for construction. Using the deep foundation strategy, contractors can utilize the existing soil using this method and guarantee the safety and integrity of the building. Areas located near coastal regions or significant water bodies are likely to experience the impacts of unstable soil during construction. Through deep foundations, they can mitigate the effects that arise from construction on unstable soil.

Why You Should Use Deep Foundation

Apart from maintaining the integrity and stability of the soil, there are many reasons which prompt contractors to use deep foundations in construction. Though one could argue that the presence of weak soil, compromised soil, undocumented fills, and liquefaction are reasons for deep foundations, this is true. All these factors pose a threat to the structural integrity and can risk the lives of workers or the loss of property.

A deep foundation helps deal with weak soils likely to fall if there is a shallow foundation on the construction site. Weak soils cause foundation failures because they result in falling if a small foundation is dug. The soil is generally unstable and could shift quickly during construction, prompting contractors to go deeper into the ground.

Another reason why deep foundations are required is compressible soil, which decreases in volume, also known as soil densification. It is not advisable to construct a building on compressible soil. Even though the effects are not immediately observed, a building on this type of soil is likely to be pulled down over time, hence the need for deeper foundations. An experienced Concrete contractor in Spring Hill, FL (or the ones elsewhere) is often needed to ensure the deep foundations are properly installed and that the soil is adequately prepared before the construction of the building begins.

There are situations where the soil on the construction site has never been documented, and therefore little is known about it. This is dangerous since you are not aware of the soil’s stability, among other determining factors that guide and inform construction. It is imperative to consult a geotechnical engineer to help in determining the soil’s integrity and viability for construction.

Liquefaction is common in areas experiencing soil saturation, and there is a high risk of earthquakes and other hazards. Liquefied soil is known for turning the solid components in soil into liquid. This could pose a major risk to the construction leading to collapse. To avoid this, a deep foundation should be made to enhance the stability of the soil and the building in general.

What Are the Different Types of Deep Foundation?

Two major types of deep foundations are commonly used in construction: Drilled piers and Driven piers. These are the main and most effective deep foundation solutions for areas with weak subsurface soil. Consulting a professional helps you identify the type of soil on your site and the necessary recommendations for a stronger building.
