There are many different solutions offered for waterproofing a basement. One such option is an Exterior French Drain.

Shown in this photo are the French drain itself (filled with water), a fill of stone, and the backfilled soil.
One way of basement waterproofing that many contractors will suggest for waterproofing a basement is to install a french drain system along the outside perimeter of your home.
To install an exterior French drain, the contractor will take the following steps:
At Foundation Systems of Michigan, we do not recommend this type of drainage system installed in your home. Instead, we suggest installing an interior basement drain along the inside perimeter of your basement or crawl space. For a free waterproofing quote in the Michigan area, call or e-mail us today!
You can expect the contractors to create huge heaps of excavated soil all around your home, creating a mess.
The installation time is twice as long or more than if you choose to have an interior system put in.
Exterior french drain systems can easily clog with dirt and other debris, as seen above.
French drain systems have been installed on the outside of homes since the 1920s, and if they were the best way to dry a basement, Foundation Systems of Michigan would be installing them, too.
Unfortunately, placing a French drain or exterior footing drain along the outside is a recipe for failure. When you put a drainage system several feet under the earth, even in a bed of gravel, it will eventually clog with dirt, roots, and debris.
Sometimes, a contractor will try to stop this by laying down a layer of filter fabric around the drain. In this case, instead of the drain clogging, the filter fabric does and won't let water into the pipe. Other problems such as freezing pipes and improperly sloped lines are also common. This type of exterior drainage commonly will not handle water that collects under your basement floor, in which case you'll still need a sump pump inside your basement. Some contractors even connect the exterior drains to the sump pump inside. Now that's sure to clog!
What happens when your drainage system clogs? It will need to be excavated and you'll have to start over. Who wants to do that again?
