When French Drains are needed
Persistent standing water: If your property frequently experiences standing water, particularly after rain or snowmelt, a French drain might be necessary to efficiently redirect water away from your building.
Water entering the basement or crawlspace: Excess water can find its way into your basement or crawlspace, which may lead to mold, rot, and compromised structural integrity. If you're noticing water infiltration in these areas, it's time to consider installing a French drain.
Sloped property or poor grading: If your property is situated on a slope, or if your building's grading directs water towards the foundation, a French drain can help keep the water at bay by controlling and directing it away from your property.
Hydrostatic pressure: When excess water accumulates in the soil around your foundation, it can exert pressure that moves water through the walls and into your basement. A French drain can relieve this hydrostatic pressure and prevent water infiltration.
