Exterior Waterproofing for Oconomowoc homes

Oconomowoc is built around water. Fowler Lake and Lac La Belle sit right against the city, the Oconomowoc River runs between them, and the groundwater under many neighborhoods rises and falls with the lakes. For an older home a short walk from Fowler Lake, that means the soil around the basement can stay saturated for long stretches, especially after the spring thaw. Walls that have held up for decades start to show it with musty corners, damp block, and water creeping in at the floor.

Out on the edges of the city, newer subdivisions face a different mix. The houses are younger and usually have poured concrete, yet they sit in clay that was disturbed during construction and never fully settled back. Clay swells, frost goes deep, and every storm adds more pressure. When water gets through a crack in a newer Oconomowoc basement, the cause is almost always outside the wall. Treating it from inside mostly moves the problem around.

Exterior waterproofing goes straight to the source. Our crew excavates to the footing, repairs the concrete, applies a liquid membrane, and hangs dimple board so water drains down to new weeping tile in a bed of washed gravel. On lots near the lakes, we pay extra attention to where that drainage discharges. The soil goes back in graded away from the house. Nick or Luis will walk you through it at the inspection, and if the City of Oconomowoc requires a permit, we pull it.

What's Included

What exterior waterproofing in Oconomowoc includes

Near the lakes or out in the newer parts of Oconomowoc, every exterior waterproofing job we do comes down to 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 Oconomowoc 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.

Oconomowoc exterior waterproofing FAQs

It's likely part of it. Groundwater near the lakes rises with the season and keeps the soil wet against your walls. Sealing the outside and giving that water new weeping tile to follow is the dependable fix.
Weeping tile needs a discharge point, and on lake lots that's something we plan carefully. Often it runs to a sump crock with a pump that sends it away from the house. We'll show you the route before we start.
Soil near moving water can hold more moisture, especially in spring. That puts steady pressure on your foundation. A sealed wall and fresh drainage at the footing are built for exactly that.
Not necessarily. Poured walls crack under clay pressure even when they're built well. We'll look at the crack and the drainage and give you a written quote to seal it for good.
It depends on the job. When the City of Oconomowoc requires a permit, we pull it and handle the inspection. That's part of our work.
If the smell comes from water soaking through the walls, yes. Musty air usually follows damp concrete. We'll check for moisture and staining and tell you what's causing it.
Ask how old the stains are and whether they're active. Have us look before closing, and you'll get a written quote you can take to the seller. Knowing the scope puts you in a stronger position.
We only dig along the walls that need it. The soil goes back in as graded backfill when we finish. Plants and edging along those walls can be moved ahead of time.
We brace it first. Carbon fiber straps or steel beams stop the movement, and then the waterproofing goes on a stable wall. Sealing a wall that's still moving won't last.
