French Drain Vs. Surface Drain

A strong functioning drain is essential for all residential and commercial properties that have problems with rainwater. This prevents water from collecting around the base that can lead to gradual foundation damage. Not all drains, though, are created the same; various forms exist. Two of the common styles are French and surface drains. One may be more suitable than the other depending on the location and type of building. Here is a quick rundown:

  • Use a Surface Drain when you can focus all water to one location. A Surface Drain (area drain) only collects surface water.
  • Use a French Drain when unable to focus water (broad collection). A French Drain collects subterranean as well as surface water.

French Drain

French drains are located underground and designed to remove water that seeps below ground surface. There is an open pipe that is out of sight where water can drain before reaching deeper into the soil or collecting around the foundation.

A French drain usually consists of a perforated pipe installed inside a hollow trench that’s covered with gravel and other porous material.

Surface Drains

Surface drains, by contrast, are installed with the drain opening flush or below with the ground level. These drains rely on surface slope to encourage water into the basins.

Which Is Better?

The more suitable option for your home depends on several factors. Most properties in the Garland, TX, area can actually benefit from a French drain since soil conditions in the region are highly porous.

Surface drains are effective for quickly draining surface water in a short amount of time. They are best for homes located on a flat surface where insufficient sloping exists to draw the water away.

Often, we recommend a combo drainage system consisting of both drain styles. This removes the majority of surface water while also addressing any runoff that manages to seep into the soil.

In any case, both require careful installation to ensure the drains perform to standards. With French drains, for example, installers must take the slope of the soil into consideration as well as be mindful of possible root intrusions. Both French and surface drains must be made from high-quality materials. Ultimately, the French drain vs surface drain debate is a non-issue because both types of drains are effective for different home foundations.
