Where French drains help
- Groundwater collection A perforated pipe collects water that moves through the surrounding gravel and directs it away.
- Foundation protection French drains can reduce moisture pressure around foundations and basement areas when properly located.
- Landscape drainage They can improve soggy lawn areas and reduce persistent saturation in low or slow-draining soil.
- Retaining wall drainage Subsurface drainage can help relieve water pressure behind retaining structures.
- Residential systems Home projects are typically designed around yards, foundations, patios and localized drainage issues.
- Commercial systems Larger sites may require higher-capacity pipe, deeper excavation and coordination with broader stormwater infrastructure.
