The problem: water coming in all the way around
When water shows up along more than one wall, fixing one corner just moves the leak. This basement needed protection around the entire perimeter, so we waterproofed all 250 feet of foundation wall.
How interior waterproofing works
- Break out the concrete floor along the inside of every foundation wall.
- Dig the trench down along the footing, where the water pressure builds up.
- Lay perforated drain tile in clean stone so water can flow freely.
- Run the drain tile to a sump pit, where a sump pump sends the water outside, away from the house.
- Pour new concrete over the trench so the floor is flat and finished.
Water that used to push through the cove joint and the walls now drops into the drain tile and gets pumped out before it can reach the basement floor. More about interior waterproofing.
What it costs
Interior waterproofing is priced by the foot of wall, approximately $60 to $120 per foot, and most jobs fall between approximately $2,000 and $35,000. A full-perimeter system like this one is at the bigger end because it covers every wall. Our waterproofing comes with a 25-year transferable limited warranty.
