FAQ:

Q: What is the best way to waterproof a basement?

A: Concrete sealers are simple ways to waterproof your basement walls and flooring. Sealers, while effective, are only appropriate for small amounts of moisture. Sizeable cracks and large leaks will require the help of a professional. You can apply your sealer using paint brushes and rollers.

Q: How do you seal a basement?

A: Using a roller which is free from lint, put down the sealer on to the basement floor. You should work in continuous motions in order to ensure that the floor becomes wet and shiny. These sealers are intended to penetrate the floor of the basement. A few coats will have to be put down, one following another.

Q: What is the best vapor barrier for basement walls?

A: Polyurethane sheeting is a typical vapor barrier that contractors use to prevent moisture from penetrating the walls of a basement. The material is stapled to the frame of a basement wall before it is finished with plaster or drywall. A vapor barrier is also helpful to keeping a basement insulated and warm.

Q: How much does it cost to waterproof a basement?

A: The cost for waterproofing a basement can range from $500 to $3,500 depending on the extent of the waterproofing and amount of work involved.
