Summer storms bring relief from the heat, but they also bring the risk of flooding and foundation damage—especially in areas like ours that are prone to heavy rainfall. While flooding is often top of mind, the long-term effects on your home’s foundation are just as important. Knowing how flooding impacts your foundation can help protect your home and its value.
How Flooding Can Damage Your Foundation
Soil Erosion and Shifting
Excess rain saturates the soil around your foundation. In areas with clay or sandy soils—common in our region—this moisture can cause the ground to shift, expand, or erode, leading to an unstable foundation with potential cracks or uneven settling.Hydrostatic Pressure
Floodwaters can create hydrostatic pressure around your foundation, pushing against the walls. This can cause cracks, bowing, or even wall failure, particularly in basements and crawl spaces.Water Seepage
Cracks in your foundation allow water to seep into basements or crawl spaces. Prolonged exposure to moisture can weaken structural materials, promote mold growth, and speed up foundation deterioration.Foundation Settlement
After a flood, the soil beneath your home may settle unevenly. This can result in a shifting foundation, leading to cracked walls, sloping floors, and misaligned doors or windows.
Key Signs of Foundation Damage After a Storm
Watch for these signs after a heavy storm:
Cracks in foundation walls or floors, especially widening or horizontal/diagonal cracks.
Standing water or persistent dampness in basements or crawl spaces, leading to mold and decay.
Sloping floors or uneven surfaces—sticking doors and windows are signs of shifting.
Bowing or cracked walls, both inside and out, from water pressure.
Water pooling around your foundation, signaling drainage issues or poor grading.
How to Protect Your Foundation
While flooding can’t be entirely prevented, these steps help reduce damage:
Improve Drainage
Ensure gutters and downspouts are clear and direct water away from your foundation. Proper yard grading prevents water pooling near your home.Seal Cracks
Inspect your foundation regularly for cracks and seal them quickly to block water from entering your home.Install a Sump Pump
A sump pump can be crucial for removing water from basements or crawl spaces. Make sure it’s maintained and ready for storm season.Waterproof Your Foundation
Apply waterproof coatings to your foundation, particularly if you live in flood-prone areas. This protective layer prevents moisture intrusion and foundation damage.
What to Do if You Suspect Foundation Damage
If you notice any signs of foundation damage, act fast! Ignoring the issue could lead to costly repairs. Call a professional foundation repair company for a thorough inspection and expert advice. Solutions may include sealing, underpinning, or other repairs to stabilize your foundation.
