Are there any preventative measures I can take to avoid future foundation problems?

Yes. Ensure good drainage around your property to keep water from pooling near the foundation. Install and maintain gutters and downspouts to channel water away from your house. Regularly check and fix any cracks or leaks in your foundation. Keep the soil around your foundation consistently moist, avoiding both dryness and oversaturation. Also, plant trees and large shrubs far enough away to prevent roots from disturbing the soil or the foundation itself.
