Signs of foundation problems include:
cracked walls, ceilings, and floors, bowing walls, and sloping floors. Don’t forget to check the doors and windows for sticking or being a little lopsided or out of place. If your basement is leaking, be sure to check the waterproofing system on it.
Also, you might want to consider installing a drainage system to complement the
waterproofing. Drainage systems divert water away from the foundation to prevent flooding and leaking.
