Exterior waterproofing Oconomowoc 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 Oconomowoc 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.

Oconomowoc is a Lake Country city ringed by water. Lac La Belle, Fowler Lake, and Okauchee Lake all sit close by, and that keeps the water table high across much of the area. When the table sits near the top of your footing, water leans on the wall all season long. Older lakefront and downtown homes often have block or stone 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, but the wall stays wet and the water finds another path.

We are based at 2128 Easy St in Waukesha, a short drive down the road, 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 Lake Country homeowner 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 Oconomowoc

Proven exterior waterproofing built for Oconomowoc

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 the clay soil around Oconomowoc 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.

Oconomowoc exterior waterproofing FAQs

Usually it is the strongest option. Homes near Lac La Belle and Fowler Lake sit over a high water table, so water leans on the wall all season. Sealing the outer face and draining at the footing keeps that pressure off the block. At the free inspection we confirm where the water is getting in first.
Yes. A lot of older homes near downtown Oconomowoc have stone or block walls, and those are the ones we seal most. We dig to the footing, clean and parge the rough stone, then coat it with membrane and add drainage. The uneven face is normal and we prep it so the seal holds.
We only open the ground along the wall that leaks and leave the rest of your lot alone. We protect the area while we work, then backfill with washed gravel and soil and re-grade so water slopes away. Grass and plantings can go back after, and our own crew runs the dig so the site stays tidy.
That is the point of it. The clay soil around Oconomowoc soaks up snowmelt every spring and swells against the wall. Sealing the outside and running weeping tile at the footing drains that water away before it can push through. One Lake Country homeowner we sealed stayed bone-dry the first spring after.
Most jobs run a few days. It depends on how much wall we open, how deep the footing sits, and how easy the yard is to reach with equipment. The clay soil here digs slower than sand, so we build that into the timeline you get in writing before we start.
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 leak that keeps coming back. Interior drain tile is easier on the yard and the budget. We give you an honest read at the free inspection.
It comes down to 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 runs more than an interior system. You get an honest written quote after a free in-home inspection, with no guessing over the phone.
