What is the difference between interior and exterior waterproofing?

Interior waterproofing manages water that has already entered your basement by directing it to a sump pump through perimeter drainage channels installed beneath your floor. Exterior waterproofing prevents water from reaching your foundation walls by applying a waterproof membrane and drainage board to the outside of your foundation. At Scaldino Basement Solutions, our team evaluates your specific moisture problem to recommend the most effective approach. Many homes benefit from a combination of both methods. Interior systems are less disruptive to install and work well for hydrostatic pressure issues, while exterior solutions address the root cause of water infiltration at the foundation wall surface.
