Exterior Waterproofing for Waukesha homes

Waukesha is where our trucks park at night. The shop sits at 2128 Easy St, so when a basement in town starts taking water after a storm, we can usually be standing in your yard sooner than anywhere else we work. That matters with exterior waterproofing, because water coming through a wall rarely waits. Homes near downtown and along the Fox River often have older foundations that have been patched from inside for decades, and the patches keep failing because the water is still sitting against the outside of the wall.

The city has a little of everything. Older houses close to downtown often sit on block walls, while the postwar neighborhoods and newer subdivisions farther out mostly have poured concrete. They share the same glacial clay, which holds water against the foundation after snowmelt and heavy summer rain and builds hydrostatic pressure until something gives. Exterior waterproofing takes that pressure away where it starts. We excavate down to the footing, clean and repair the wall, roll on a liquid membrane, hang dimple board, and set new weeping tile in washed gravel so the water has somewhere to go.

Being local means Nick or Luis can look at your walls the same week you call, often sooner. They'll show you where the water is getting in, tell you honestly whether digging is the right fix or whether interior drain tile would do the job, and hand you a written quote. When the City of Waukesha requires a permit for the work, we pull it. The yard gets backfilled and graded to shed water away from the house, and the lifetime warranty transfers if you ever sell.

What's Included

What exterior waterproofing in Waukesha includes

Every exterior waterproofing job we do in Waukesha, from the older blocks downtown to the newest subdivisions, gets these four pieces:

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 Waukesha 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.

Waukesha exterior waterproofing FAQs

For an older block wall that seeps every spring, exterior work is usually the most complete fix. We seal the whole outside face and give the water new weeping tile at the footing. You stop fighting the same leak every year.
Our shop is on Easy St, so Waukesha is the quickest trip we make. Same-week visits are common, and in town it's often sooner. Call and we'll give you a real time slot.
Being near the river often means wetter soil around your foundation. The membrane and dimple board keep that water off the wall, and new weeping tile carries it away at the footing. We look at your lot and its grade before we recommend anything.
Maybe, maybe not. Gutters and grading sometimes play a part, and we'll check them. When the wall itself is letting water through, digging to the footing and sealing it is the lasting fix.
Some exterior jobs need one, depending on the scope. When the City of Waukesha requires a permit, we pull it and handle the inspection. You don't have to call the city yourself.
We dig a trench along the wall being waterproofed, down to the footing. The soil gets piled nearby and goes back in as graded backfill when we're done. Plants and pavers in the way can be moved first, and we'll talk it through with you before we start.
A damp smell can come from humidity or from water getting through the walls. We'll check the walls and the floor joint for moisture and staining. If water is coming through, you'll get a written quote for the fix that fits, and sometimes that's interior drain tile.
Yes. Once the wall is exposed, we clean it and repair cracks before the membrane goes on. If the wall is bowing, we brace it first, because waterproofing belongs on a stable wall.
Most exterior jobs take a few days, depending on how many walls we do and how deep the footing sits. We keep the site tidy and backfill as soon as the drain tile and membrane are in. Weather can shift the schedule a bit.
It does. Our lifetime warranty transfers to the next owner. That's a real selling point when a buyer's inspector looks at the basement.
