The two sources measure differently, which is why their waterproofing ranges don't match.
What drives the price
- Linear feet of wall or drain tile
- Finished basements, since drywall and flooring must come out and go back in
- Excavation access: decks, driveways, and landscaping
- Whether structural repair is needed before waterproofing
- Permits, engineering reports, and the length of the warranty
