In theory, a waterproofing failure would result in significant damage to the foundation structure and require professional plumbing and construction help. It can cause considerable damage to the walls and may require complete reconstruction.
We say “in theory” because it’s an extremely rare outcome that ostly happens when people try to waterproof their basements with DIY kits from the store, with no skills or experience.
