Exterior Waterproofing for Milwaukee homes

A lot of Milwaukee houses were standing long before anyone thought about waterproofing a basement. Bungalows, Milwaukee duplexes and old brick homes sit on block, brick and fieldstone walls that have taken a century of freeze and thaw. Mortar gets soft, the original clay tile at the footing silts up, and a heavy summer storm finds every weak joint at once. When the sewers back up and the ground is saturated, that water has nowhere to go but into the wall.

Exterior waterproofing goes after that water where it starts. We dig along the wall down to the footing, scrape and clean the face, and repair loose mortar, cracks and missing pieces before anything gets coated. Then a liquid membrane goes on, dimple board covers it, and new weeping tile is laid at the footing in washed gravel. The backfill is graded so surface water runs away from the house. On an old stone or brick wall, that prep work is most of the job, and we take our time on it.

Milwaukee lots are often narrow, with a walk on one side and a neighbor's driveway on the other, so we plan the dig carefully and protect what we can. Nick or Luis will look at the wall from inside and out and tell you which sides actually need the work. You get a written quote with the scope spelled out. When City of Milwaukee permitting requires a permit for the job, we pull it.

What's Included

What exterior waterproofing in Milwaukee includes

On an older Milwaukee foundation, exterior waterproofing comes down to four pieces of work along each wall we open up:

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 Milwaukee 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.

Milwaukee exterior waterproofing FAQs

Yes, stone walls can be done from outside. We clean the face, repoint the worst joints and fill the voids before the membrane goes on. Stone takes more prep than block, and that prep is what makes the membrane stick.
Water coming up through the floor drain usually points to the sewer side. Water running down the wall or along the cove where wall meets floor points to the foundation. We look at where the water shows up and where it stains before recommending any digging.
In most old homes that tile is cracked, shifted or packed with silt, so it stopped working a long time ago. New perforated weeping tile in washed gravel gives the water a clear path again. It gets laid during the same dig as the membrane.
Often we can, with hand digging and careful shoring in the tight spots. Sometimes that side is better handled from inside with drain tile, and we'll tell you that plainly. You'll see the plan for each wall before we start.
Only after the loose material comes off. We scrape and clean the wall down to solid masonry, patch it, and then apply the membrane. Skipping that step is why cheap coatings peel.
It depends on the scope of the work. When City of Milwaukee permitting requires one, we pull it and handle the inspection. You don't have to deal with the paperwork.
Some of it has to move to reach the footing. We'll walk the line with you, set aside pavers and plants where we can, and regrade the soil when we backfill. Anything that has to come out is spelled out in the quote.
The wall comes first. A moving wall will crack any membrane put on it. With the wall already dug out, it's a good time to straighten and brace it, then seal it.
A single wall is often a few days from digging to backfill. A full perimeter takes longer, depending on access and weather. We cover open trenches and keep the site safe until it's closed up.
Yes. The lifetime warranty transfers to the next owner. Buyers like seeing documented exterior work on an older home.
