An interior basement waterproofing system uses a series of drainage channels that are installed along the inside of your foundation walls. These drains then run to a sump pump which will remove the moisture from your basement. The drainage system can be a French drain ($50-$1,000), baseboard channels ($30 per linear foot) or subfloor drain tiles ($25-$55 per square foot). A dehumidifier is also often recommended to keep humidity levels low, preventing condensation from building up.
This type of interior waterproofing system is effective for preventing moisture from seeping through fine cracks in the basement walls. However, it isn’t a good solution for areas where the water problem is a result of hydrostatic pressure against the concrete foundation. Waterproof sealants block evaporation, but they don’t address the source of the moisture which is more likely to be caused by a failing drainage system or ground saturation.
Exterior basement waterproofing is a more involved process that requires excavation to reach your foundation walls. This can be costly and may require extensive landscaping, driveways or porches to be removed. This solution can be more expensive than the interior system, but it’s a much stronger and longer-lasting option. It’s important to choose a waterproofing contractor who will use an approved and durable membrane such as a synthetic, rubber or polyurethane membrane. These are typically applied in thick rolls that are bonded to the surface of your basement walls and then covered with a layer of gravel.
When comparing quotes, be sure to get an estimate that includes all the work necessary to complete the project. For example, the contractor should dig down to and repair any clogged or broken footer tile. They should then install an interior or exterior drainage system to prevent future problems.
One of the most common reasons for a damp basement is an overloaded drainage system. This can happen if the soil next to your house is too loose and floods or if gutters are blocked and cause rainwater to cascade down alongside the foundation instead of away from it. This can also be caused by missing or poorly designed window wells, which allow water to pool in the earth underneath the windows. If this is a problem, the drainage system can be improved by installing new gutters and downspouts or by digging a French drain in the yard.
