Interior Drain Tile for Delafield homes
In Delafield, a lot of houses are built right into the hillside. The front door is at street level, the back opens onto a walkout, and the rear or side walls of the basement are buried deep in the slope. Every rain and every spring thaw sends runoff down that hill toward the house. It soaks into the glacial clay behind the buried walls and sits there, pressing in. Homes on the rises around Lake Nagawicka see it most after a wet April, when a line of water appears along the uphill wall.
Interior drain tile works well in a walkout because the problem is concentrated. The uphill wall and the side walls that step down the grade carry most of the load, and the open walkout side usually stays dry. We trench along the buried walls, set perforated pipe in washed gravel next to the footing, and run it to a sump crock placed where it can discharge downhill. A pump moves the water out, and a battery backup keeps running when a summer storm cuts power.
Nick or Luis will walk the slope outside with you as well as the basement, because where the ground falls tells us where the water is going to push. Sometimes a partial system along the uphill side covers the whole problem, and we'll say so. The work happens from inside, so your terraced yard and any retaining walls stay put. When the City of Delafield requires a permit, we pull it, and the system comes with a lifetime transferable warranty.
