Waterproofing done while the walls are open.
When structural work exposes a foundation, we waterproof it before it's covered again: membrane, drainage board and new weeping tile outside, or interior drainage inside.
When we waterproof as part of the job
- Underpinning or rebuilding a wall that also leaks
- Excavating for a walkout or an addition
- Water coming in where a wall is bowing
- Finishing a lowered basement and want it dry
What actually happens
- 01
Find the way in
We trace where water is actually entering. Sometimes a crack, sometimes grading, sometimes the whole wall.
- 02
Pick the right system
Exterior: excavate, membrane, drainage board, new weeping tile. Interior: drainage channel to a sump. We tell you which and why.
- 03
Install & restore
Clean excavation, proper backfill and compaction, site put back the way we found it.
Priced in writing, after we've seen it.
What moves the price
- Exterior or interior system
- Linear feet of wall and depth
- Access: decks, driveways, AC units, tight lots
How we quote
