Exterior French Drain Basement Waterproofing – Is It the Right Method for You?
Having an exterior French drain system installed is one method of basement waterproofing. In general, there are two main methods of home waterproofing – interior and exterior waterproofing (also known as positive- and negative-side waterproofing, in that order).
Because of the extensive installation method, an exterior French drain is best installed while the home is still under construction. To install this drainage system, a contractor will dig about six to eight feet down around the perimeter of the home install a waterproof membrane around the exterior foundation walls, and then put in the drainage system to channel water away from the home. However, some homeowners still opt to have this system installed while they are living in the home. In this case, before excavation begins, the homeowner will need to call a special service number in order to have the location of all underground utilities (such as plumbing and electrical) marked. This way, contractors can be sure to avoid these lines when they are digging. After this is complete, the homeowner will need to further prep their home for excavation. This will include preparing any landscaping for excavation.
Because exterior waterproofing and installing a French drain can be such a hassle, many homeowners opt for an interior basement waterproofing system, and at BDry, we install the BDry Basement Waterproofing System, which is an interior waterproofing solution that was first patented in 1966. If you would like more information on this system and to schedule an in-home consultation where one of our representatives will be able to complete a thorough investigation of your home and basement, contact BDry today.
