Option 7: Seal cracks in foundation walls and basement floor

Sealing cracks is a simple way to help reduce basement flooding in your home and neighbourhood. Sealing cracks will help you reduce the chances that you’ll have infiltration flooding, and can reduce the amount of flood water that enters the municipal sanitary sewer system through your basement floor drain. In many cases, cracks can be effectively sealed from inside the basement, and you will not have to dig anywhere beside the foundation to repair them.

Talk to a plumber, contractor or check your local hardware or home improvement store for the best types of products for this job. If cracks appear to be severe, you may require the assistance of a qualified contractor or structural engineer, as severe cracks may represent a structural issue with the home and may require more substantial repairs.
