Interior waterproofing systems help control groundwater after it reaches the foundation. By collecting and redirecting water through specially designed drainage channels, these systems help keep basement spaces dry while reducing the risk of recurring moisture problems. Interior waterproofing is often recommended for homes experiencing seepage along wall-floor joints or areas where groundwater pressure is affecting basement walls.

Typical Cost: $70–$95 per linear ft.

Exterior waterproofing addresses water before it reaches the foundation wall. This process typically involves excavating around the foundation, applying waterproof membranes, and improving drainage conditions around the home. Exterior waterproofing is one of the most effective ways to reduce hydrostatic pressure and protect foundation walls from long-term moisture exposure.

Typical Cost: $95–$245 per linear ft. 

Typical Cost: $1,500–$20,000 per project
