Basement waterproofing
Exterior foundation waterproofing
Exterior waterproofing excavates soil down to the footing, cleans and repairs the wall, applies a waterproof membrane and drainage board, and installs new footer drains before backfilling. It stops water at the outside of the wall.
- Typical time
- Two to five days per wall or more.
- Repair or replace
- Choose for problem walls or with structural work.
It's most often used on one problem wall, when walls also need structural work, or when a finished basement makes interior drainage impractical.
Access is the limit: driveways, porches, patios and close neighbors can make excavation difficult.
