Exterior Waterproofing for Delafield homes
In Delafield, a lot of houses are built into the hill. The front looks like a ranch, the back opens onto a walkout, and the wall buried deepest faces uphill. That buried wall takes the brunt of it. Every thaw and every hard rain sends water sliding down the slope toward the house, and it collects against the foundation right where the soil is deepest. When we get calls from Delafield about a wet basement, the water is usually coming through that uphill wall or the corners where it meets the side walls.
Homes near Lake Nagawicka add another layer, because the ground closer to the water stays damp longer and the glacial clay underneath does little to drain it. Clay holds water, swells, and presses on block or poured concrete until seams open up. Sealing from inside can't relieve that pressure. Digging along the buried walls to the footing lets us repair the concrete, coat it with liquid membrane, add dimple board as a drainage layer, and lay fresh weeping tile in washed gravel that carries runoff around the house toward the low side of the lot.
Slopes make the backfill matter as much as the membrane. When we close up the trench, we grade the soil so surface water is steered around your foundation and off toward the downhill side. Nick or Luis will walk the lot with you first, look at where the water runs in a storm, and give you a written quote. If the City of Delafield requires a permit for the excavation, we pull it. Our crew comes out from the shop in Waukesha, a short drive away, and same-week visits are common.
