Basement walls are a crucial component of any home’s foundation. However, they are susceptible to various factors that can cause them to weaken and fail. In this section, we will explore the numerous reasons that lead to basement wall deterioration.
One leading cause is the use of “portland cement,” which is actually not a type of cement but is instead a term used to describe a particular blend of cement and other materials. This blend can be less durable than other types of cement, and over time, it can lead to the degradation of the walls.
In addition, exposure to turbulent weather such as heavy rain or flooding can also weaken basement walls. This can occur due to water penetration, which can lead to cracking and deterioration.
Overall, it is crucial to take preventative measures to protect your basement walls, such as using high-quality cement blends, installing proper drainage systems, and regularly inspecting the walls for any signs of damage or wear.
Factors such as portland cement use, exposure to turbulent weather, inadequate curing, weak concrete mixture, old age, and overload can cause basement walls to crumble
Crumbling basement walls may be caused by various things. These can be turbulent weather, insufficient curing, weak concrete blend, age and overload. Quick drying from insufficient curing can make walls brittle and vulnerable to exterior pressure. Low mineral content or other weak concrete can lead to wall degradation over time. Aging materials, combined with unstable foundations, can also cause the walls’ structural integrity to be compromised. Heavy machinery or too much weight on top of the walls can also be a cause.
To fix crumbling basement walls one must start by preparing the surface. This is done by removing any loose or powdery concrete. This is done with a wire brush or power washer before cleaning it with a vacuum. Then epoxy must be added to make the basement waterproof. A coating should also be put on to stop moisture leaving from inside out as trapped water can hasten wall destruction. After this, the wall should then be resurfaced with mortar. Thin layers should be skimmed on. If there are any thicker cracks, these should be filled with a mix of sand on both the inside and outside, if possible. Professional help should be sought for more extensive cases.
In order to avoid crumbling basement walls a good drainage design needs to be used to move water away from the walls to sump pumps. Waterproofing should be done regularly and maintenance routines should be kept up to date, like sealing hoses. Filling voids with stones and mortar can help stabilise the walls’ structures. Adding wire mesh with a parging layer can also offer extra strength. In more severe cases, professional aid is recommended.
Finally, data  shows that a concrete mixture with low Portland cement can result in crack structures in walls.
