Why Is Your Concrete Foundation Crumbling?
Freezing and Thawing
One of the primary causes of concrete foundation issues is freezing and thawing temperatures. When water enters porous or damaged surfaces, it can freeze during colder months, causing the surface to expand and crack. This repeated cycle of freezing and thawing leads to more damage over time.
Soil Movement
Changes in soil movement caused by improper drainage and soil compaction can also be to blame for concrete foundation issues. If there is too much moisture in the soil, it can cause it to expand and put pressure on your foundation walls. This pressure will eventually lead to the cracking or crumbling of your foundation.
Substandard Work
In some cases, substandard workmanship or materials may be the cause of your foundation’s crumbling. Poorly mixed concrete and incorrect installation can lead to unstable foundations that crack over time. It’s important to hire a reputable contractor who has experience installing concrete foundations correctly, to avoid these issues.
Minerals in the Soil
The minerals in the soil can also cause your concrete foundation to crumble. Certain minerals, such as calcium and magnesium, are naturally found in the soil. When these minerals come into contact with water or moisture, they dissolve and form an alkaline solution that reacts with the concrete, causing it to weaken and eventually crack.
De-icing Salt
One of the biggest culprits of concrete foundation problems is de-icing salt. When spread on driveways, sidewalks, and patios, these salts can make their way into cracks in the concrete, weakening it over time. The reaction between the salt and water can also cause corrosion to occur, leading to further damage to your foundation.
Too Much Water
If there is too much water in the soil around your foundation, it can cause the concrete to become unstable, leading to cracks and eventual crumbling. Proper drainage systems and grading should be installed to ensure that excess water is directed away from your home’s foundation.
Tree Roots
The root systems of trees surrounding your house may also be damaging your foundation. As the roots grow, they can push against your foundation walls, causing cracks or other damage over time. If you notice any trees close to your home’s foundation, it’s important to have them removed as soon as possible to avoid further damage.
Improper Maintenance
Finally, improper maintenance or neglect can be a major factor in crumbling concrete foundations. It’s important to inspect your foundation regularly and address any issues as soon as they arise. This will help keep your foundation in good condition and reduce the risk of major damage over time [2].
