Concrete settling is a common issue that affects home and business owners alike, especially for those who live in areas with constant fluctuating weather and varying soil conditions. It happens when the ground beneath the concrete shifts, which causes the surface to sink or in most cases crack. Although concrete is known for its high tolerance to stress and being very durable, the strength of the soul beneath it is essential to its integrity. Understanding why concrete settling happens and how to prevent it can help protect your property from potential damage and costly repairs.
Why Does Concrete Settle?
One of the most common causes of concrete settling is the erosion or compaction of the soil underneath it. Over long periods of time, the soil underneath the concrete may erode due to water constantly coming into contact with it or natural settling. The loss of soil underneath the concrete in certain spots causes it to collapse under its own weight. Poor soil preparation during the construction of the concrete fixture can contribute to settling, especially if it wasn’t properly compacted beforehand.
Water damage is another significant factor that can lead to concrete settling. Excessive water, whether from heavy rainfall or improper drainage, can wash away soil particles, causing erosion and leaving voids beneath the concrete. When water pools under concrete, it weakens the soil structure and accelerates settling. Additionally, in areas with expansive clay soils, the ground can expand when wet and shrink when dry. This constant shifting can destabilize the foundation beneath concrete slabs, leading to cracking and settling over time.
How to Prevent Concrete Settling
The most effective way to prevent your concrete from settling and cracking is to make sure that there is proper drainage around your property. Water drainage systems like gutters, downspouts, and other drainage systems help direct water away from your concrete surfaces, greatly reducing the risk of water damage to the soil underneath. This will help maintain the stability of the soil beneath your concrete and prevent unnecessary shifting.
Soil stabilization is also essential in preventing settling. Before pouring concrete, it’s important to ensure that the soil is adequately compacted and stable. In some cases, you may need to add a soil stabilizer or even regrade the land to provide additional support. By addressing weak or unstable soil conditions, you can create a more solid foundation for your concrete.
Also, tree roots can especially cause damage to your concrete surface. As a tree grows, its roots can expand and disrupt the ground under the concrete, which causes uneven surfaces and eventual cracks. Make sure you regularly maintain the trees around your concrete surfaces to ensure their roots do not invade.
Conclusion
Concrete settling is a common but serious issue that affects countless home and business owners. However, with proper care, maintenance, and attention, it can be prevented. Installing effective drainage systems around your property to divert water from going under your concrete, stabilizing the soil, and addressing any tree roots that may grow underneath and around the concrete can all greatly improve and help protect your concrete surfaces. Regular inspections are also a great way to catch early signs of settling. If your concrete has already settled, contact us at The Concrete Lifter to save and fix your concrete surface!
