Exterior waterproofing Muskego 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, so it stops before it ever reaches your Muskego basement. This is the most thorough way to keep a basement dry, and it fits a high-water-table setting like Muskego well because it seals and drains the wall from outside where the pressure comes from.

Muskego sits around Big Muskego Lake and Little Muskego Lake, wrapped by extensive wetlands, and much of the city carries a notably high water table. Groundwater and hydrostatic pressure press hard on basement walls here, so wet basements are common. The clay-heavy soil swells every spring when the melt and rain soak in. Many older homes have block foundations, and those leak at the cove joint where the wall meets the footing and through cracks in the block. Interior patches cover the inside while the block stays wet, and the water finds another path.

We are based 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 coming in, dig along that wall, seal it, and drain it, then back the work with a lifetime transferable warranty. One homeowner near Little Muskego 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 Muskego

Proven exterior waterproofing built for Muskego

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 Muskego 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.

Muskego exterior waterproofing FAQs

Muskego sits low near Big Muskego and Little Muskego Lake, and the water table runs high through much of the city. When spring melt and rain saturate the clay soil, groundwater rises and pushes hydrostatic pressure against your walls until it works through the block. Sealing the wall from the outside and draining it at the footing is what stops that.
For a home near the Muskego lakes with a high water table, exterior work is the most thorough fix because it seals the wall face and drains the water away before it ever touches the block. Interior drain tile still keeps a basement dry and costs less. We look at your yard and water level at the free inspection and give you an honest call.
We only dig along the wall that is leaking and leave the rest of your Muskego property alone. We protect the surrounding area, 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 and rising groundwater that soak Muskego clay every spring drain away before they can push through. One homeowner near Little Muskego Lake stayed bone-dry the first spring after we sealed the outside.
Usually yes. Interior sealers and patches cover the inside of the block, so groundwater keeps soaking the wall from outside and finds a new way in. Exterior waterproofing seals the wall face and carries the water away at the footing, which is why it holds when inside fixes have failed on older Muskego block foundations.
Most jobs run a few days, depending on how much wall we open up and how easy the yard is to reach with equipment. Muskego clay is slower to dig than sandy soil, and a high water table can mean extra dewatering, so we factor both into the timeline you get in writing before we start.
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.
