Foundation Waterproofing in Halifax & Nova Scotia

Exterior foundation waterproofing involves exposing the outside of the foundation wall, repairing cracks where needed, applying waterproofing membrane protection, and installing drainage where required to help move water away from the home.

A foundation waterproofing membrane is a protective layer applied to the outside of the foundation wall to help prevent water from entering through concrete, block, cracks, or weak points in the wall. Aquatight commonly uses Blueskin and may use other membrane products depending on the project.

A Delta air-gap membrane is installed over the waterproofing layer to add protection and help manage water along the exterior foundation wall.

No. Aquatight installs exterior weeping tile where required. It is not necessarily needed on every exterior waterproofing job.

Exterior weeping tile, also called exterior drain tile, is a perforated drainage pipe installed near the foundation footing to collect water and direct it away before pressure builds against the foundation wall. Aquatight uses perforated, filtered 4-inch drainage tile covered with clear gravel where required.

Exterior weeping tile is used when water is entering the basement and needs to be managed around the foundation. A French drain is typically used for surface water above grade that is running toward the house and needs to be diverted toward lower ground where possible.

Yes. Aquatight can install French drains as a standalone service if requested.
