A french drain is a type of basement waterproofing system that keeps water from penetrating a basement. These drains utilize plastic pipes with holes drilled in the bottom to collect rain and redirect it away from a home’s foundation, preventing damage to the home. French drains are susceptible to clogging, and to keep a french drain system functioning properly, it must be maintained. Soil and debris have a tendency to build up inside the pipes, eventually stopping water from flowing. To keep this water remediation system functioning as intended, follow these maintenance tips.
