One specific problem that occurs in all foundation types is called spalling. Spalling happens as a result of water gathering at the base of the foundation vertical wall. The paint line on a foundation only goes down to the level of the soil, but moisture travels deeper. When atmospheric conditions raise the temperature, evaporative moisture wicks up the exterior side, between the paint and sealant, and into the porous texture of the concrete surface. When this moisture goes upward and escapes, it leaves behind efflorescent salt deposits that deteriorate the concrete and delaminate the paint. The visible damage on the vertical face of footing walls is called spalling, which creates holes and chips. This damage must be patched, waterproofed, and painted all the way down, below the soil saturation of moisture.
Here are some examples of spalling concrete damage. This is what to look for when checking your foundation for damage and other related problems. Call us today if you have any questions.
