The problem

This Birmingham home needed water stopped at the foundation, from the outside.

Why we went outside the wall

Exterior waterproofing stops water on the outside of the foundation before it reaches the basement wall. It’s the right call when you want the water kept off the wall itself, or when the inside of the basement is finished.

How we fixed it

Excavated along the foundation
Installed a new drainage membrane on the wall and a French drain at the footing
Backfilled the trench
Restored the yard

The result

The homeowner has a dry basement, and the work was done in July, well before winter. Our workmanship on the membrane is backed by our 25-year transferable limited warranty. The French drain at the footing is drainage and isn’t covered.
