Exterior waterproofing Pewaukee homeowners actually trust

When a basement wall keeps letting water in, the water is coming 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, so it stops before it ever reaches your Pewaukee 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.

Pewaukee wraps around Pewaukee Lake and splits into the City and the Village, and homes on both sides feel the water. Near the lake the water table sits high, and that groundwater pushes straight against your basement walls. Many lots run sandy over a clay layer that shifts as the moisture changes through the seasons. Older block foundations soak up the water and let it in at the cracks and the cove joint where the wall meets the footing. Interior patches cover the inside face, and the block stays wet and finds another way through.

We are based nearby at 2128 Easy St in Waukesha, and Nick, Luis, and our own crew have sealed these walls since 1998. During a free inspection we find where the water is really getting in, dig along that wall, seal it, and drain it, then back the work with a lifetime transferable warranty. One homeowner near the lake 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 Pewaukee

Proven exterior waterproofing built for Pewaukee

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. Through the clay layer under many Pewaukee 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.

What your Pewaukee neighbors say

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.

Pewaukee exterior waterproofing FAQs

Yes. Homes near Pewaukee Lake sit on a high water table, so we build the drainage for that. We seal the wall face and set weeping tile at the footing to carry groundwater away before it can push through the block. During the free inspection we check how high the water sits at your lot and size the system to match.
We only dig along the foundation wall that leaks 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 our own crew does the digging 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. Pewaukee lots often run sandy over clay, and the clay layer is slow to dig, so 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 and rising groundwater that saturate Pewaukee soil every spring drain away before they can push through. One homeowner near the lake 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. Older block foundations soak up water through the block and let it in at the cracks and the cove joint. Exterior waterproofing seals the wall face and drains the water away at the footing, so the block stays dry and the leak stops. That is why it holds when inside patches keep failing.
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.
