The most common way builders waterproof a basement is with a spray-on sealant. This can be damaged when the contactor backfills soils and the house moves or shifts. Any exterior drain tile that may have been installed can become silted, closed, or even damage by this as well. If you are seeing any amount of water in the home, whether it is a couple drops to a pool of water, call Midwest to get an inspection set up. We will send out a expert to find where the source of water is coming from and provide you a permanent solution to keep your basement dry.
