It is easy for moisture to negatively impact your foundation because all the water from heavy rain and melted snow will absorb into the surrounding soil. However, the soil is only capable of holding so much water weight before it either washes away or grows extremely heavy. This creates an immense pressure against your foundation, causing it to shift away from this weight or even crack altogether. When winter comes and that trapped water freezes, the expanding ice then can lead to the foundation cracking apart from within. Water seeping into your foundation also causes mold growth and other unwanted conditions within the home.
