Causes of spalling in concrete walls
Spalling in concrete walls, including basement wall spalling and spalling concrete foundation, can occur due to several reasons. One of the primary causes is the freeze-thaw cycle, which happens when moisture seeps into the concrete and then expands upon freezing, causing cracks and disintegration of the spalling foundation.
This occurs because water expands by about 9% when it freezes, exerting pressure on the surrounding concrete. As a result, the concrete weakens and eventually starts to flake off, leading to spalling.
Another common cause is water penetration, especially when the concrete lacks proper waterproofing or has inadequate drainage. When water seeps into the concrete, it can corrode the reinforcing steel, weakening the structure and contributing to spalling in the basement wall or concrete block spalling.
The constant exposure to moisture weakens the concrete and further contributes to spalling. Additionally, poor construction practices, such as using low-quality materials or improper curing techniques, can also contribute to spalling in the foundation over time.
It is crucial to ensure that the concrete is properly mixed, cured, and protected from moisture to prevent spalling and maintain the structural integrity of the walls.
