Exterior Waterproofing for New Berlin homes

New Berlin covers a lot of ground, and its houses cover a lot of decades. Ranches from the 1950s sit a few miles from split-levels built in the 70s and 80s and newer homes from the 90s. The split-levels are the ones that surprise people. That lower family room sits only partly below grade, so the soil outside is right at window height, and when the clay gets saturated in spring, water seeps through the wall under the carpet or finds the joint where wall meets slab.

That half-buried wall can be handled directly from the yard. We excavate along the foundation down to the footing, which on a split-level is often a shallower dig, clean and repair the wall, and apply a liquid waterproof membrane. Dimple board covers it, new weeping tile goes in at the footing bedded in washed gravel, and the soil comes back graded away from the house. On a full ranch basement it's the same system, only deeper.

Our shop in Waukesha is close by, and we cover the whole city, north end to south. We come to you. Nick or Luis looks at the whole foundation, the grade on each side, and where the downspouts drop water, then gives you a written quote for the walls that actually need work. Same-week appointments are common, and financing is available. When the City of New Berlin requires a permit, we pull it.

What's Included

What exterior waterproofing in New Berlin includes

On a New Berlin ranch or split-level, exterior waterproofing includes these four steps:

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 New Berlin 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.

New Berlin exterior waterproofing FAQs

Often, yes. In a split-level that room sits partly below grade, and wet soil against the wall pushes water through. Sealing the outside of that wall and adding footing tile usually solves it.
Yes, and the dig is usually shallower. We go down to the footing, seal the wall and add new weeping tile. It's the same system on a smaller scale.
Yes, all of New Berlin is in our regular area. Our shop is in Waukesha, so it's a short drive. Same-week appointments are common.
Usually only the wall that leaks. We check the grade and downspouts on that side, then dig, seal and drain that stretch. If other walls show signs, we'll point them out.
It depends on the work. When the City of New Berlin requires a permit, we pull it and handle the inspection. You don't need to do anything.
Wall-floor joint seepage is often better handled with interior drain tile under the slab. If the wall itself is also wet, exterior work may still make sense. We'll tell you which one your house needs.
Room to work helps. A clear side yard lets equipment reach the wall and gives us space to set the soil aside. We'll still mark anything you care about before we start.
Poured walls from that era can still crack, and the original footing drainage can clog. Clay soil and deep frost work on every house, new or old. The fix is the same: seal the wall and give the water a clear path.
Yes, financing is available. Ask about it when Nick or Luis goes over your quote. It's common on the bigger exterior jobs.
Keep gutters clean and downspouts extended so they drop water away from the house. The grading we leave slopes away, so avoid piling mulch or soil back against the wall. The membrane and new footing tile do the rest.
