Foundation cracks often occur because of soil movement, especially in areas with clay-heavy soil. When it rains, the soil expands, and when it dries out, it shrinks, putting pressure on your foundation. Another common culprit is poor drainage around the house. Too much water pooling near your foundation can weaken it over time. Even changes in temperature can cause materials to expand and contract, leading to cracks. Many homeowners invest in exterior foundation membranes to keep moisture from getting to the foundation.
