Exterior waterproofing Wauwatosa homeowners actually trust

When a basement wall keeps leaking, the water is getting in from the outside, so that is where the real fix belongs. Exterior waterproofing seals the wall on its outer face and drains the water away at the footing, which stops it before it ever reaches your Wauwatosa basement. It is the most thorough way to keep a basement dry, and it is a smart call for the older homes that fill this part of Milwaukee County.

Wauwatosa is an established suburb, and a lot of its houses went up between the 1920s and the 1950s on block, brick, and stone foundations. Decades of settling take a toll, and the clay soil here swells every spring as it soaks up snowmelt and rain. That saturated soil leans on aging walls, and mature neighborhoods take on water when a heavy rain rolls through. Homes near the Menomonee River sit lower, where the ground stays wet longer. Interior patches cover the inside, and the old block or stone stays wet while the water finds another way in.

We are based nearby at 2128 Easy St in Waukesha, and Nick, Luis, and our own crew have been sealing walls like these since 1998. During a free inspection we find where the water is really coming in, dig along that wall, seal it, and drain it, then back the work with a lifetime transferable warranty. One homeowner in an older Wauwatosa neighborhood had fought a wet wall for years; we sealed the outside and their basement stayed bone-dry through the next spring thaw.

How We Waterproof It in Wauwatosa

Proven exterior waterproofing built for Wauwatosa

Excavation down to the footing

We dig carefully along the leaking wall to expose it top to bottom, all the way to the footing, so the full face can be sealed. On older Wauwatosa lots this is slow, deliberate work.

Liquid waterproof membrane

After cleaning the wall and patching cracks with hydraulic cement, we coat the whole surface with a thick elastomeric membrane that seals out the water for good.

Dimple board + weeping tile drainage

A dimpled drainage board gives water an air gap to fall down, and perforated weeping tile at the footing collects it and carries it away from your home.

Washed gravel backfill & regrading

Clean washed gravel wraps the weeping tile for fast drainage, then we backfill the soil and re-grade so the surface slopes water away from the foundation.

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.

Wauwatosa exterior waterproofing FAQs

Yes. A lot of Wauwatosa homes from the 1920s through the 1950s sit on block, brick, or stone, and those older walls are exactly what exterior waterproofing was built for. We dig to the footing, seal the wall face, and drain the water away, which is the surest way to keep an aging basement dry.
It should. Old stone and mortar walls leak where water soaks through the joints from outside. When we seal the outer face and add weeping tile at the footing, the water is carried off before it can reach those joints. We check the wall at the free inspection so we treat the real problem.
We only dig along the affected foundation wall and leave the rest of your Wauwatosa yard alone. We protect the surrounding area while we work, then backfill with washed gravel and soil and re-grade so water slopes away. Grass and plantings can be replaced, and our own crew does the digging so the site stays under control.
That is the whole point. Sealing the outside of the wall and adding weeping tile at the footing means the snowmelt that swells Wauwatosa clay every spring drains away before it can push through. One homeowner in an older neighborhood stayed bone-dry the first spring after we did the outside.
Yes. Homes near the Menomonee River sit where the ground stays wet and the water table runs high after heavy rain. Exterior waterproofing seals the wall and the weeping tile carries the water away at the footing, which is how we keep low-lying Wauwatosa basements dry.
Usually yes. Interior sealers and patches cover the inside of the wall, so water can keep soaking an old block or stone wall from outside and find a new way in. Exterior waterproofing seals the wall face and drains the water at the footing, which is why it holds when inside fixes have failed.
It depends on how long the wall is, how deep the footing sits, and how easy it is to get equipment to the dig on an older lot. Because it involves excavation it costs more than an interior system, and you get an honest written quote after a free in-home inspection, with no guessing over the phone.
