Basement Waterproofing questions, answered by experts

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.

Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts
