There is much more variety in the placement of an exterior French drain system. This variation will depend on the unique characteristics and specific details of your property as well as the ultimate goal of the French drain system. Some common locations where you might consider installing a French drain include:

Along the Exterior Perimeter of the Foundation: This particular configuration helps to effectively redirect water away from the foundation, preventing it from seeping into the basement or crawl space and potentially causing significant water damage.

Dowslope Areas: If a property is situated on a slope or incline, French drains can be strategically installed uphill from the building. This setup intercepts and redirects water that flows downhill, effectively managing runoff and reducing the risk of water-related issues.

Driveways and Patios: In areas that are prone to water pooling on driveways, patios, or walkways, the installation of French drains can significantly mitigate water accumulation and improve overall drainage, enhancing safety and usability of these outdoor spaces.

Around Access Points: Exterior French drains can be strategically placed around basement windows, window wells, or stairwell entrances to prevent water from entering these particularly vulnerable openings, thereby safeguarding your home's interior against moisture intrusion.

Excess water that is pooling near your foundation or under your slab can lead to significant structural issues if not managed properly. The installation of a French drain is an effective solution for this problem. This system begins with the creation of a trench around the affected area, which is lined with filter fabric to prevent soil and sediment from clogging the drainage system.

Once the trench is prepared, it is filled with geo filter material such as crushed stone. This allows water to flow through while filtering out debris. As the water accumulates in the trench, it enters the perforated drainpipe installed within the crushed stone layer. This pipe is pitched at a slight angle, allowing gravity to guide the water toward the designated outlet. In interior systems, this outlet typically leads to a sump pit, while exterior systems should direct water to the best drainage area, away from the foundation.

By installing French drains, homeowners can effectively prevent water accumulation around their properties. This proactive maintenance can significantly improve drainage, safeguarding the structural integrity of the home and maintaining a dry, healthy environment in and around the foundation.
