Exterior Waterproofing for South Milwaukee homes

A lot of the houses in South Milwaukee were built in the early 1900s, and their basements show it. Old block and brick walls, soft mortar, and a history of patch jobs layered one on top of another. We often find hydraulic cement smeared over a crack, a coat of waterproof paint over that, and a fresh damp spot right next to both.

People renovating these older homes usually find out about the basement once they start opening walls. The house is worth the work, and the foundation has held for a century, but it was built with little or no drainage at the footing. The clay near the lake and Grant Park holds water through every snowmelt and storm, and old brick and block soak it up. Inside patches keep failing because the water is still pressing from outside.

Exterior waterproofing gives an old foundation what it never had. We dig to the footing, clear off loose material, repair cracks and failed joints, and seal the wall with a liquid membrane and dimple board. New weeping tile in washed gravel carries water away, and the backfill is graded to slope off. Structural issues get handled first so the seal goes on a stable wall. When the City of South Milwaukee requires a permit, we pull it.

What's Included

What exterior waterproofing in South Milwaukee includes

On an older South Milwaukee foundation, exterior waterproofing includes 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.

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.

Questions, Answered

South Milwaukee exterior waterproofing FAQs

Patches on the inside can't stop water that's pushing from outside. The pressure finds the next weak spot. Sealing the outside and giving the water a drain is what finally stops it.

Yes, do the foundation first. Finishing a basement on a wet wall wastes the money you put into it. Once the walls are dry, you can build out the space with confidence.

Yes. We dig to the footing, clean the brick, repair the mortar joints and apply the membrane. Brick needs extra care, and we'll look at its condition before we start.

It can be both. Water washing through the joints for years softens the mortar. We'll check whether the wall is moving and repair or brace it before sealing.

Some jobs need one. When the City of South Milwaukee requires a permit, we pull it and set up the inspection. You won't have to handle it.

No. We lay new weeping tile at the footing during the dig, bedded in washed gravel. It gives a century-old basement the drainage it never had.

Usually yes. We plan the dig around the space you have and can do some of it by hand where needed. We'll look at access on the first visit.

We dig in sections and look at the wall as it's exposed. Anything weak gets repaired before sealing. If the wall is moving, we brace it first.

Same-week appointments are common. We'll walk the basement, look at the old patches and tell you what's causing the water. You'll get a written quote.

It should. The lifetime warranty transfers to the next owner. A documented repair on an old foundation gives buyers real peace of mind.
