Exterior waterproofing Waukesha 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 Waukesha basement. It is the most thorough way to keep a basement dry, and it is the right call for a chronic leak or a finished space you want to protect.

Waukesha sits on heavy clay in the Fox River valley, and that clay holds water. Every spring the snowmelt and rain soak it, and the saturated soil pushes hydrostatic pressure straight against your foundation. Older homes near downtown and along the river often have block or stone walls, and those leak at the cove joint where the wall meets the footing and through cracks in the block. Interior patches cover the inside, but the block stays wet and the water finds another path.

We are based right here at 2128 Easy St in Waukesha, and Nick, Luis, and our own crew have been sealing these walls 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 near the Fox River 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 Waukesha

Proven exterior waterproofing built for Waukesha

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. In Waukesha clay 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.

Waukesha exterior waterproofing FAQs

Often yes. If the leak keeps coming back through one Waukesha wall, we only excavate along that wall and seal it from the outside, which keeps the cost down and the rest of your yard untouched. During the free inspection we confirm the water really is coming through that wall so we seal the right spot.
We only dig along the affected foundation wall and leave the rest of the property 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 the digging is done by our own crew so the site stays under control.
Most jobs run a few days, depending on how much wall we open up and how easy the yard is to reach with equipment. Waukesha clay is slower to dig than sandy soil, and we factor that into the timeline you get in writing before we start.
That is the whole point. Sealing the outside of the wall and adding weeping tile at the footing means the snowmelt that saturates Waukesha clay every spring drains away before it can push through. One homeowner near the Fox River stayed bone-dry the first spring after we did the outside.
Both keep a basement dry, and the right one depends on your home. Exterior waterproofing stops water at the wall and is the most thorough fix, which is worth it for a finished basement or a chronic leak. Interior drain tile is less invasive and easier on the budget. We give you an honest recommendation at the free inspection.
Usually yes. Interior sealers and patches cover the inside of the wall, so water can keep soaking the block from the outside and find a new way in. Exterior waterproofing seals the wall face and drains the water away 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. 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.
