Basements in the Des Plaines River corridor
Nearly every Des Plaines house has a basement, and along the Des Plaines River corridor a fair number of them have taken water at some point. That history shapes the install more than the wall type does. Interior basement partitions are ordinary 2x4 framing and behave like any stud wall upstairs. The perimeter is a different animal: drywall on 1x2 furring strips over poured foundation or foundation block, and furring strips hold nothing. Your installer drives straight through them into concrete with 1/4-inch Tapcons set 1-1/4 inches deep, hammer drill running, which puts the job into masonry-surcharge territory. Then we plan around the water. Point out the highest line you have seen and the bracket, the receiver shelf and every plug sit at least 18 inches above it. Anything below grade gets CL2-rated cable. We keep the amplifier off the cold exterior wall, since freeze-thaw pushes moisture through foundation hairlines every March and bare block sweats in July. A dehumidifier near 50% keeps the gear healthy. Basement installs run 60 to 90 minutes.
