Exterior Waterproofing for Pewaukee homes

Around Pewaukee Lake, groundwater sits close to the surface, and lakeside basements feel it first. After snowmelt or a week of storms, the soil around a foundation near the shore fills up and stays full. Water presses on the walls from every side, finds the cracks and the joint at the bottom of the wall, and shows up as damp stains, puddles, or a steady trickle. Many of these homes have been living with it for years, a dehumidifier humming and boxes kept up on shelves.

Away from the shore, many Pewaukee subdivisions were built on former farm fields. That ground is heavy glacial clay, and once it was dug up and pushed back around new foundations, it swells with every wet season and holds water against the concrete. Different setting, same result: pressure on the wall and water looking for a way in. Exterior waterproofing handles both situations by stopping the water outside the wall, where the trouble begins, so the basement stays dry through spring and summer alike.

The work follows the same sequence at every house. We excavate down to the footing, clean the wall and fix any cracks, apply a liquid waterproof membrane, and cover it with dimple board so water drops straight to new weeping tile set in washed gravel. Graded backfill finishes it. Pewaukee has both a City and a Village, so the permit comes from whichever one your address falls under, and when it's required, we pull it. Nick or Luis will come out, usually the same week you call.

What's Included

What exterior waterproofing in Pewaukee includes

For Pewaukee homes near the lake or out in the newer subdivisions, every exterior waterproofing job includes these four parts:

Excavation to the footing

We dig along the leaking wall down to the footing so the whole face of the foundation can be cleaned, repaired and sealed.

Liquid waterproof membrane

Cracks get hydraulic cement, then the wall gets a thick elastomeric membrane that keeps water off the concrete.

Dimple board and weeping tile

Dimple board gives water a gap to drain down, and new perforated weeping tile at the footing carries it away.

Washed gravel and regrading

Washed gravel around the tile keeps it draining, then we backfill and grade the soil to slope away from the house.

Warning Signs

Signs your Pewaukee home needs exterior waterproofing

  • Water seeping through the wall after heavy rain or the spring thaw
  • White chalky efflorescence on the block
  • A musty smell that never leaves the basement
  • Paint peeling or bubbling off a foundation wall
  • Water pooling against the foundation outside after a storm
  • An old leak that interior patches never stopped

What homeowners say about our crew

★★★★★

They replaced our drain tile, put in a sump pump, set steel beams, and sealed the basement walls - then redid the window wells and buried a downspout outside. The price was competitive and Nick, Luis and the crew explained everything as they went.

Pewaukee exterior waterproofing FAQs

We can't lower the lake, but we can keep water off your walls and give it a route away. The membrane and dimple board seal the outside face, and new weeping tile at the footing collects the groundwater. We make sure it discharges somewhere useful.
Often, yes. Weeping tile has to empty somewhere, and on low lakeside lots that's usually a sump crock with a pump. We'll look at your lot and tell you what the drainage needs.
Former farm fields around Pewaukee are heavy clay, and clay backfill holds water against the foundation. Newer poured walls still crack and leak under that pressure. Sealing the outside and adding fresh weeping tile takes the pressure off.
It only changes who issues the permit. When your address needs one from the City or the Village, we pull it. You don't have to figure out which office to call.
It can be. Near the lake, groundwater can keep walls wet long after the rain stops. We'll check for staining and moisture at the walls and floor joint to tell you where it's coming from.
Usually. We plan around the slope and how the lot drains toward the lake. If digging on one side is impractical, we'll show you other options like interior drain tile.
That's efflorescence, minerals left behind as water moves through the concrete and dries. It's a sign the wall is soaking from outside. Exterior waterproofing stops the water that causes it.
Pewaukee is close to our shop in Waukesha. Same-week appointments are common. Call and we'll set a time.
It does. The lifetime warranty transfers to the new owner. Buyers and inspectors like seeing documented waterproofing with a warranty behind it.
We trench along the walls we're waterproofing, so plants right against the house do get disturbed. You can move anything you want to keep before we start, or we'll set it aside carefully. We finish with graded backfill ready for new planting.
