Exterior waterproofing Delafield 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. It stops the water before it ever reaches your Delafield basement. It is the most thorough way to keep a basement dry, and it earns its keep on a chronic leak or a finished space you want to protect.

Delafield sits in Lake Country on the Bark River, close to Nagawicka and Nemahbin lakes. The ground here is rolling glacial moraine, and near the lakes the water table runs high, so groundwater presses straight against basement walls. Older homes downtown and along the lakefront often have block or stone foundations, and those take on water at the cove joint where the wall meets the footing and through gaps in the masonry. Patch the inside and the block still stays wet, so the water finds another path.

We are based at 2128 Easy St in Waukesha, a short drive from Delafield, and Nick, Luis, and our own crew have sealed these walls since 1998. During a free inspection we find where the water is truly getting in, dig along that wall, seal it, and drain it, then back the work with a lifetime transferable warranty. One homeowner had fought a wet wall for years; we sealed the outside, and their basement stayed bone-dry straight through the next spring thaw.

How We Waterproof It in Delafield

Proven exterior waterproofing built for Delafield

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. Near the Delafield lakes we work with the high water table the whole way down.

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 Delafield 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.

Delafield exterior waterproofing FAQs

Yes. Near Nagawicka and the Bark River the water table sits high, so groundwater presses on the wall from outside. Sealing the wall face and draining the water at the footing takes that pressure off before it reaches your Delafield basement.
We only dig along the wall that leaks and leave the rest of the 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 go back, and our own crew runs the dig.
Often it is the right call. Older downtown and lakefront homes in Delafield have block or stone foundations that soak up water at the cove joint. Sealing the outer face and draining at the footing keeps those walls dry in a way interior patches cannot.
That is the point of it. Sealing the outside and adding weeping tile at the footing carries the snowmelt away before it can push through. With Delafield sitting on glacial moraine near the lakes, that spring surge is exactly what we build the system to handle.
Both keep a Delafield basement dry, and the right one depends on your home. Exterior waterproofing stops water at the wall and is the most thorough fix, good for a finished basement or a chronic leak. Interior drain tile is less invasive and easier on the budget. We give an honest recommendation at the free inspection.
Usually yes. Interior patches cover the inside of the wall, so with a high water table the block stays wet and water finds a new way in. Exterior waterproofing seals the wall face and drains it 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 the yard is to reach with equipment. 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.
