Should you waterproof your foundation?

When building a house, a waterproof layer is often applied to the base to prevent moisture from entering the ground. This approach does not prevent water from entering the basement through gaps, cracks and holes during construction.

Should you waterproof your foundation?

When building a house, a waterproof layer is often applied to the base to prevent moisture from entering the ground. This approach does not prevent water from entering the basement through gaps, cracks and holes during construction. Effective waterproofing of the basement should avoid moisture and water. A dry basement is a fun basement.

More than that, you'll be happier. Heavy rains can eventually weaken the foundations of your home if they are not protected. This situation will increase the cost of repairs. Dry basements protect against water and moisture damage, and waterproof foundations resist flooding and leaking for added peace of mind as a homeowner.

Use putty to seal doors, windows, and window openings. We recommend an elastic sealant such as Big Stretch Sealant or Lexel Sealant, both waterproof and flexible. If the foil test showed that water soaks into the basement walls and leaves them damp, seal the inside of the walls with a high-quality waterproof paint, such as DRYLOK White Extreme Waterproof (available from Home Depot). Another waterproofer once told me that in one of his jobs the general contractor sent a worker, after applying the waterproofing, to break the form ties inside a base.

If you are using a waterproofing subcontractor, keep in mind that good waterproofers can be in high demand during the peak season.
