FRENCH DRAINS

West Hollywood

Why Are French Drains Necessary?

Foundation leaks, Basements leaks, Crawl space leaks

Licensed Certified Drainage Technicians

• French drains are designed to channel below grade water against foundation away from your residence.
• Rain runoff from roof, roof gutters, and down spouts can pour hundreds of gallons of water saturating the below grade soil against your foundation creating hydrostatic pressure. 

Foundation Drainage Prevents Leaks

• Below grade hydrostatic pressure against the foundation forces water by capillary action into exterior concrete cracks, and voids causing foundation leaks and elevated interior moisture.

Foundation leaks, Basement Leaks, Crawl Space Leaks

French Drain Installations Questions? Call Today 1-888-650-0111

• French drains “perforated drain pipes” are designed to collect and discharge below grade ground water at footing location.
• Positioning french drain level below top of foundation footings, lowers the water reservoir elevation.
• Minimizing the water reservoir also reduces hydrostatic pressure to footing and foundation.

Elevated hydrostatic Pressure Increases Potential For Foundation Leaks

• Pea gravel applied 4” under french drain perforations “weep holes” to allow water to percolate into french drain weep holes sloping to discharge location.
• Pea gravel filters the ground water of silt and sediment prior to percolating into the french drain weep holes to prevent clogging of drainage system.

• Positioning french drain along footing allows adjustments of 1/4” sloping for gravity flow of below grade ground water to discharge location.

Warning!

• Some contractors install french drain on top of footing with no sloping at all.
• Sloping a 10 foot section of french drain would require raising drain 2.5” per 10 foot section of drainage.
• A 40 foot section of drain would require raising drain 10” above footing elevation creating hydrostatic pressure to foundation waterproofing.
• Maintaining a low water reservoir for water percolation into drain prevents hydrostatic pressure.

Curb Core For French Drain

• Providing 1/4” slope per foot of Drain Pipe Allows For Gravity Flow of Water To Discharge Curb Core Location.
• French drains are only used along the foundation perimeter and transitioned to solid drain pipes to street curb.

WARNING!

• Some contractors drill core flush with bottom of curb restricting drainage flow during rain storms due to street curb water runoff.
• The curb core must be positioned 3/4” above the base to allow water to flow out and prevent back flow into drain pipe.
