How to Install a French Drain

How to Install a French Drain: Protecting Your Concrete

Water is concrete's enemy. Proper drainage prevents water damage, settling, and foundation problems. A French drain diverts water away from your concrete and foundation. This guide covers how to install one correctly.

Why French Drains Matter

French drains prevent:

• Water pooling around foundations
• Concrete settling from saturated soil
• Freeze-thaw damage
• Foundation problems

Installation Steps

1. Plan the route: Determine where water needs to go (away from structures)
2. Dig the trench: 6-12 inches wide, 18-24 inches deep, with slope (1 inch per 8 feet minimum)
3. Line with landscape fabric: Prevents soil from clogging drain
4. Add gravel base: 2-3 inches of gravel
5. Install perforated pipe: Place pipe with holes facing down
6. Cover with gravel: Fill trench with gravel, leaving 2-3 inches from top
7. Fold fabric over: Wrap fabric over gravel
8. Backfill: Cover with soil or sod

The Bottom Line

French drains protect your concrete and foundation by diverting water away. Proper installation requires correct slope, gravel, and perforated pipe. This investment prevents costly water damage.
