When it comes to protecting your home from water damage, French drains are one of the most effective and time-tested solutions available. But what exactly are they—and how do you know if your property needs one?

What Is a French Drain?

A French drain is a trench filled with gravel or rock that contains a perforated pipe, designed to redirect water away from your home’s foundation. It works by collecting excess groundwater or surface water and channeling it to a safe discharge point, like a storm drain or dry well.

How Does It Work?

Water naturally follows the path of least resistance. A French drain gives water an easy route to flow away from your property—reducing pressure on your foundation, preventing basement flooding, and keeping crawl spaces dry.

Signs You Might Need a French Drain:

  • Water pooling in your yard or near your foundation
  • Wet or soggy spots that don’t dry out
  • Basement water intrusion or damp crawl spaces
  • Cracks forming in your foundation walls
  • Mold or mildew smells from below-grade areas

Benefits of Installing a French Drain:

  • Protects your foundation from water damage
  • Prevents erosion and standing water
  • Improves drainage and yard usability
  • Supports other waterproofing systems like sump pumps
