Exterior Waterproofing for North Prairie homes

North Prairie is mostly single-family homes, and a lot of them are in newer subdivisions on flat prairie ground near the Kettle Moraine State Forest. Flat land sounds easy on a basement, but it can be the opposite. Water has nowhere obvious to run, so after snowmelt or a heavy storm it sits in the yard and soaks straight down along your foundation. That's why so many sump pumps in North Prairie run long and hard every spring.

Newer houses here mostly have poured concrete walls. As poured concrete cures, it shrinks, and that leaves thin vertical cracks in many basements. Plenty of them stay dry for years. Then the clay around the house gets saturated, hydrostatic pressure builds, and one of those shrinkage cracks starts to weep. Sealing one crack from inside can work. When several are seeping and the pump barely keeps up, the wall is sitting in water, and the fix belongs outside.

Exterior waterproofing opens the ground to the footing so we can clean the wall, repair the cracks and seal the whole face with a liquid waterproof membrane. Dimple board goes over it, new weeping tile is set at the footing in washed gravel, and the backfill is graded to move water off that flat yard and away from the house. When the Village of North Prairie requires a permit, we pull it. Nick or Luis will look at your walls first.

What's Included

What exterior waterproofing in North Prairie includes

On a North Prairie lot where water likes to sit, exterior waterproofing comes down to four pieces:

Excavation to the footing

We dig along the leaking wall down to the footing so the whole face of the foundation can be cleaned, repaired and sealed.

Liquid waterproof membrane

Cracks get hydraulic cement, then the wall gets a thick elastomeric membrane that keeps water off the concrete.

Dimple board and weeping tile

Dimple board gives water a gap to drain down, and new perforated weeping tile at the footing carries it away.

Washed gravel and regrading

Washed gravel around the tile keeps it draining, then we backfill and grade the soil to slope away from the house.

What homeowners say about our crew

★★★★★

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.

Questions, Answered

North Prairie exterior waterproofing FAQs

Poured concrete shrinks as it cures, and thin vertical cracks are common in newer basements. Most are harmless until the soil outside stays wet. Then they become the path water uses.

A pump that runs that often means a lot of water is reaching your footing. It's doing its job, but it's working hard. Sealing the walls from outside and adding new weeping tile can take load off the basement side.

Yes, flat ground lets water sit and soak down along the foundation. We regrade the backfill so it slopes away from the house. Combined with a sealed wall and footing drain, that cuts off the water's easiest route in.

Maybe not. A single leaking crack can often be sealed from inside, and we'll tell you if that's enough. If several cracks are wet or the wall shows moisture across its face, exterior waterproofing is the lasting fix.

We do. When the Village of North Prairie requires a permit for the work, we pull it and schedule the inspection. You won't need to chase the paperwork.

Often, yes, depending on how the deck is built and where its footings sit. We look at it during the inspection and plan around it. If part of the deck has to come off, we'll tell you before quoting.

You can seal individual cracks, add interior drain tile, or waterproof from outside. The right one depends on how many walls are wet and where the water comes from. We'll look and give you a written quote.

Yes, it's much easier before drywall goes up. Fixing water after the basement is finished means tearing things out. Sealing it now protects the space you're about to build.

Some of it along the wall has to come up to dig. We lift what we can save and set it aside, then grade the backfill so you can replant. The rest of the yard stays as it is.

Yes. The lifetime warranty transfers to the next owner. In a newer neighborhood where buyers compare houses, that helps.
