A French drain is required in order to re-direct water away from your house. French drains usually get used in cases when a connection to a sanitary drain is not available. The French drain redirects water approximately 20 feet away from the house and then filters it into the ground. A very typical use of a French drain is to redirect water from downspouts around the house and eavestroughs. Also it can be used to re-direct water from the trench drain in front of your garage door. The installation of a trench drain may be provided by our company as well.
