Getting Ready To Install an Exterior French Drain
You'll Need to Remove:
Many times you can expect contractors to create huge heaps of excavated soil all around your home, creating a mess.
Plus, the process can be very expensive, costing $15,000 to $20,000 per installation with other companies.
Installation time is usually twice as long or more, than if you have an interior system installed.
French drain systems have been installed outside of homes since the 1920s, and if they were the best solution, Leader Basement Systems would be install them too.
But, placing a French drain or exterior footing drain outside a home can be a failure. When you have a drainage system a few feet under the earth, even with a gravel bed, it will clog with dirt, roots, and debris - it's just a matter of time.
Other contractors may try to stop this by laying down a filter fabric around the drain. Then, instead of the drain clogging, the filter fabric does and won't let water into the pipe.
Other problems, like freezing pipes and improperly slanted lines are common. This kind of exterior drainage will usually not handle water that collects under the basement floor. And then you'll still need a sump pump in your basement.
Some contractors even connect exterior drains to a sump pump inside the home - now that's sure to clog at some point!
What happens when your drainage system clogs? It needs to be taken out and you'll have to start over. Why would you want to do and pay for that?
