What is a French drain?

A French drain uses gravity and a sloped trench lined with gravel and perforated plastic or PVC pipe to move water away from problem areas. Water enters the gravel bed, flows into the perforated pipe, and travels downhill to a discharge point such as a storm drain, daylight outlet, or lower yard area.

These systems address several water management issues in Connecticut yards: basement seepage, soggy landscaping around the foundation, standing water in low spots, or saturated lawn areas that won't drain after rain. Rather than blocking water, a French drain redirects it, which protects foundations from hydrostatic pressure and prevents pooling that kills grass and attracts mosquitoes.

Installation depth and pipe diameter depend on the slope of your land and the volume of water moving through it. A properly graded trench (typically 1 percent slope, or 1 foot drop per 100 feet of run) ensures consistent flow. The gravel surrounding the pipe filters soil particles while allowing water to pass through freely.

Connecticut landscapers commonly install French drains along foundation perimeters, in low-lying garden beds, beside patios, and along property lines where water runoff from neighbors' yards causes problems. The system works year-round in most residential settings, though seasonal wet periods reveal whether drainage is needed.

Finding a landscaper experienced in Connecticut soil conditions and local drainage codes ensures your system performs as intended. Look for landscape design and installation providers who have completed similar projects in your region.
