Exterior Waterproofing for Greendale homes

Greendale was laid out as a planned greenbelt village in the late 1930s, and plenty of the original homes are still standing, well kept and loved. Their basements are small and were built long before modern drainage. After more than eighty Wisconsin winters, the old walls have taken a lot of frost, snowmelt and clay pressure, and damp corners or a white chalky line along the block are common.

Owners here tend to care about the look of the house and the lot. That matters for exterior work, because we are digging next to foundations, walks and gardens that have been part of the street for generations. We plan the dig with you, set aside plantings you want saved, and put the yard back graded to shed water. Above ground, the home looks the same once the soil settles and the grass fills in.

Below ground, the change is real. We excavate to the footing, clean and patch the old wall, apply a liquid waterproof membrane and cover it with dimple board. New weeping tile goes in at the footing bedded in washed gravel. That gives water a path away from a basement that never had one. When the Village of Greendale requires a permit, we pull it.

What's Included

What exterior waterproofing in Greendale includes

On an older Greendale home, 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 Greendale 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.

Greendale exterior waterproofing FAQs

Yes, when it's done carefully. We dig in sections, look at the wall as it's exposed, and repair anything weak before sealing it. If the wall shows structural movement, we deal with that first.
We backfill with graded soil that slopes away from the house and clean up the site. Grass or plantings along that strip will need replanting. Tell us which shrubs you want saved and we'll set them aside.
Maybe. A musty smell can come from dampness through the wall, or just from humidity. We'll check the walls for moisture first, and if a lighter fix is enough, we'll tell you.
That's efflorescence, minerals left behind when water moves through the masonry. It means moisture is coming through the wall from outside. Sealing the outside face stops it at the source.
No. The membrane and dimple board sit below grade, out of sight. Once the soil settles and the grass comes back, the house looks the way it always has.
That depends on the job. When the Village of Greendale requires one, we pull it and handle the inspection. You won't have to chase anything.
Many homes from that era were built without it. Without a drain at the footing, water just sits against the wall. New weeping tile in washed gravel gives it a way out.
Usually not. We look at where the roots run and plan the dig around the tree where we can. Sometimes a few roots have to be cut, and we'll talk it through with you first.
Do it before you finish the basement. Once the walls are dry, you can put in drywall and flooring without worrying about them. It also makes sense to do it before new landscaping goes in.
Yes. The warranty is lifetime and transferable. It stays with the house, whether it's sold or handed to family.
