Pros and cons of an Exterior Drain Tile Systems in Idaho and Washington

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:

  • First, the entire perimeter of your home must be cleared. Gardens, steps, porches, etc., must be removed before the work can begin.
  • Next, the contractor will dig out the perimeter of your home. Excavated dirt will be heaped around the house.
  • The drain will be laid in a bed of stone along the bottom. The stone, and possibly a layer of filter fabric, are there to protect the drain from clogging.
  • The excavated soil will be “backfilled” on top of the system. In a year, this soil will settle, and the contractor will need to return to fill in more soil.

At Premier Basement Systems, 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. It is far more reliable and less susceptible to the elements. Anyone who suggests using an exterior drainage system is just uneducated. For a free waterproofing quote in the Idaho and Washington area, call or e-mail us today!

Choosing Wisely:
The Pitfalls of Exterior French Drain Systems for Basement Waterproofing

Exterior French drain systems have been utilized for home installations since the 1920s. However, if they truly stood out as the optimal solution for basement drying, Premier Basement Systems would incorporate them into their offerings.

Opting for an exterior French drain or footing drain along the outside of your home is a strategy destined for failure. Installing a drainage system several feet beneath the ground, even within a gravel bed, is prone to eventual clogging from dirt, roots, and debris.

Occasionally, a contractor may attempt to address this issue by placing a layer of filter fabric around the drain. However, in such instances, rather than preventing the drain from clogging, the filter fabric itself becomes obstructed, preventing water from entering the pipe.

 Moreover, it often proves inadequate in addressing water accumulation beneath your basement floor, necessitating the presence of an interior sump pump.
