When building any structure, commercial or residential, you will need a strong foundation to keep it stable and to help it last for years to come. The type of foundation you may need, however, is likely to depend on the type of soil found on your chosen building site, as each type will have different qualities. Discover just how soil types can affect a project’s foundations and why the experts should be consulted in this guide.
Load-Bearing
One of the most important parts of the soil you choose to build upon is its ability to support weight. Structures are not typically lightweight, which means your soil may need a bit more support from foundations to hold the building. Typically, rocky soils will have a high load-bearing capacity, great for foundations. On the other hand, sandy soils are often moderately supportive, however they can shift under heavy loads.
Moisture and Drainage
Poor drainage can cause water to pool, which can weaken the foundation and cause instability. To prevent this, it’s important to consider how soil type manages moisture. Clay soils, for example, often expand when wet and shrink when dry, causing movement in the foundation. Loamy soils, on the other hand, are a great option, as they provide both good drainage and stability.
Erosion and Stability
Another key consideration to make when it comes to the soil you choose to build upon is how external factors might impact it. Erosion-prone soils, for example, can easily shift and fall over time, compromising how stable the structure above is. To prevent the soil from eroding easily, it may be beneficial to add retaining walls or gravel layers.
Expansive and Reactive Soils
Specific soils can react significantly to the local conditions, especially moisture changes. Clay soils, for example, are highly expansive and can cause foundations to rise or settle unevenly. This movement can have a noticeable impact on the property, causing cracks in the walls or sloped floors. Clay soils often require adjustments and special considerations, so it’s best to inform your foundation and piling services provider of the type of soil beforehand.
