Foundation Waterproofing

​What are the advantages of an interior drain compared to an exterior drain?

  • Less invasive installation: Less disruption to costly outdoor landscaping.

  • Non-limiting installation period: Can be installed year-round, unlike an exterior drain.

  • Ease of maintenance: Accessible from inside the building, easy to inspect, and never needs to be cleaned.

  • Reduced risk of exterior damage: Sheltered from the elements and potential damage caused by tree roots or debris.
