To prevent or fix frost heave, you have to either deal with the water in the ground, or the temperature of the ground, and ideally both. You need to make sure water drains away from the problem area, not towards it.
How to Fix Frost Heave?
Frost heave is a common problem in cold climates, where the soil expands and contracts due to the freezing and thawing of the ground.
This can cause damage to the foundation of a building, as well as the surrounding soil. The good news is that it can be prevented, or at least minimized, with some preventive measures.
The first step in fixing frost heave is assessing the current state of the soil. It is important to determine the cause of the frost heave, as this will allow you to determine the best course of action.
If the soil is clay–based, it is more likely to experience frost heave than other types of soil. If this is the case, it is important to add organic matter to the soil to increase its permeability and reduce the chances of frost heave.
The next step is to ensure that the soil drainage is adequate. Poor drainage can cause frost heave, as the water will not be able to escape and will instead cause the soil to expand.
You can improve the drainage of the soil by digging trenches around the building and installing a French drain. This will allow the water to collect in the trench and then be drained away. In cases where frost heave has already occurred,
