Foundation heave is a condition that can damage your home’s foundation and cause serious problems. If you suspect that your home has foundation heave, it’s important to have a professional assess the damage and determine the best course of action for repair. In some cases, foundation heave can be repaired by excavating around the foundation and installing drainage systems to improve drainage. In other cases, foundation replacement may be necessary.
If your home has foundation heave, you may notice cracks in your walls or floors, doors that stick or won’t close properly, and windows that are difficult to open. Foundation heave can also damage your home’s foundation and cause it to settle unevenly.
What is foundation heave?
Foundation heave is when the soil underneath your foundation starts to push up on the foundation itself. This can happen for a number of reasons, but it usually has to do with changes in the moisture content of the soil. If the soil around your foundation becomes too wet, it can start to expand and push up on your foundation. This can lead to cracks in your foundation, and eventually, your foundation could start to collapse.
There are a few ways to repair foundation heave, but it can be a difficult and expensive process. If you think you might have a problem with foundation heave, it’s important to get it checked out by a professional as soon as possible.
Causes of foundation heave
There are many potential causes of foundation heave, but some of the most common include:
- Soil expansion: There are several reasons why foundation heave may occur. One common cause is when the soil around the foundation expands and contracts due to changes in moisture content. This can happen when there is a prolonged drought followed by heavy rains. The expansion and contraction of the soil can put pressure on the foundation, causing it to crack or move.This is typically caused by an increase in moisture content in the soil, which can lead to the soil expanding and putting pressure on the foundation.
- Tree roots: Another common cause of foundation heave is when tree roots grow underneath the foundation and push up on it. This can happen with both mature trees and young trees that are growing rapidly. If you have trees near your foundation, it is important to have them inspected regularly to ensure that they are not causing damage. If there are trees nearby, their roots can grow under the foundation and lift it up.
- Poor drainage: One of the main causes of foundation heave is poor drainage. When water collects around the foundation, it can cause the soil to expand and push against the foundation. This can lead to cracks in the foundation and eventually cause the whole structure to collapse. To avoid this, it’s important to make sure that your home has proper drainage. You can do this by making sure that gutters are clear and directing water away from the foundation. You should also check for leaks regularly and fix them as soon as possible. If water isn’t draining away from the foundation properly, it can seep into the ground and cause the soil to expand.
- Frost: Frost is a common cause of foundation heave. When water in the soil freezes, it expands and puts pressure on the foundation. This can cause the foundation to lift up or crack. Heave can also occur when the ground around the foundation settles or shifts. This can happen if there is an earthquake or if heavy equipment is used nearby. In cold climates, frost can penetrate the ground and cause the soil to heave.
- Soil type: The type of soil on your property plays a big role in whether or not you’ll experience foundation heave. Heave is more likely to occur in areas with expansive clay soils. These soils absorb water and swell when they get wet. This can cause the foundation to rise up and crack. If you live in an area with this type of soil, it’s important to take measures to prevent heave from happening. Heaving is more likely to occur in clay soils, which expand when they absorb water and contract when they dry out.
- Plumbing leaks: One common cause of foundation heave is plumbing leaks. If a pipe bursts or leaks, the water can saturate the soil around the foundation. This can cause the soil to expand and push against the foundation, causing it to heave. Foundation heave can also be caused by changes in the moisture content of the soil. If the soil dries out, it can shrink and pull away from the foundation, causing it to settle. Leaks in your home’s plumbing can also lead to heaving by saturating the soil around your foundation.
If you suspect that your foundation is being lifted by one of these causes, it’s important to have it inspected by a professional as soon as possible. Heave can lead to serious damage to your home, so it’s best to catch it early and take care of it before it gets worse.
Problems caused by foundation heave
Foundation heave can cause all sorts of problems for your home. It can crack walls and damage the foundation itself. It can also cause doors and windows to become misaligned, making it difficult to open and close them. In extreme cases, foundation heave can even cause the house to become structurally unsound. If you suspect that your house is suffering from foundation heave, it’s important to have it inspected by a professional as soon as possible. Foundation repair is a complex and delicate process, so it’s best to leave it to the experts.
Prevention of foundation heave
The best way to prevent foundation heave is to make sure that your home’s foundation is properly constructed and maintained. If you’re having a new home built, be sure to ask your builder about the best foundation for your area. If you live in an area with a high water table, you may want to consider having a French drain installed around the perimeter of your foundation. This will help keep water away from the foundation and help prevent heave.
Foundation heave is caused by the expansion of clay soils when they become wet. The expansion puts pressure on the foundation and can cause it to crack or even collapse. There are several ways to prevent foundation heave:
- Avoid building on clay soils. If you must build on clay, make sure the soil is well-drained.
- If you live in an area with a high water table, make sure your foundation is designed to withstand hydrostatic pressure.
- Use a waterproofing barrier around the perimeter of the foundation to prevent moisture from seeping in and causing the soil to expand.
- Make sure gutters and downspouts are installed and functioning properly so that water does not pool around the foundation.
- Have your foundation inspected regularly by a qualified professional to look for signs of cracking or movement.
Foundation heave can be a serious problem, but it is usually preventable. If you take the proper precautions, you can avoid foundation damage and keep your home safe.
