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 downspouts 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.

10 Year Warranty For French Drain Installations
Foundation Leaks Create Mold Growth

  • Foundation, basement, and crawl space leaks elevate interior moisture, humidity levels creating indoor mold growth.

Foundation French Drain Installation

Foundation French Drain Installation

WARNING!

  • French Drain Must Be Positioned Below The Top of Footing To Prevent Hydrostatic Pressure.
  • Architectural Specifications Require Positioning French Drain Below The Top of Footing.

Image Below Shows French Drain In Correct Position

  • Most of the competitors DO NOT position french drain below the top of footing due to the additional excavating and preparation work involved.
  • Before Selecting CONTRACTOR, CAREFULLY INSPECT Images, And Work of Competitors French Drain Installations.

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.

Rigid French Drains Prevents Deflection Necessary To Provide Correct Sloping.

WARNING!

  • Deflections In French Drains Will Create Pooling of Water In French Drain And Affect Drainage Flow.

  • Excavating 8” below top of foundation footing allows clearance for applying a 4” gravel bed layer and positioning the 4” diameter french drain level with top of footing.
  • Additional gravel is applied 6” above top of french drain filtering the below grade ground water prior to percolating into french drains perforations.
  • French drain perforations “weep holes” are positioned downward in gravel bed allowing water percolation into perforations.
  • Reducing the volume of standing water at base of footing prevents hydrostatic pressure and water migration under footing and slab locations.

Correct French Drain Positioning At Footing Base

Correct French Drain Positioning At Footing Base

Prevents Water Build-Up At Foundation Elevation.

  • The purpose of foundation drainage is to reduce below grade water levels to a minimum, foundation water intrusion, indoor moisture, and humidity.

WARNING!

  • Some waterproofing contractors position french drain on top of footing raising the water table elevation necessary for for foundation drainage.
  • Positioning french drain on top of footing creates higher reservoir of below grade standing water at base of footing.
  • The goal of foundation drainage is to REDUCE below grade water levels preventing hydrostatic pressure to foundations, basements, and crawl spaces.

French Drain Wrapped With Filter Fabric

French Drain Wrapped With Filter Fabric

Filter Fabric Edges Are Sealed to French Drain With Waterproofing Tape

  • Filter fabric edges are sealed to prevent sediment, soil, and silt from clogging french drains.
  • Allows below grade ground water in gravel bed to percolate through filter fabric and into french drain perforations "weep holes".
  • Geo textile filter fabric wrapped three layers around "perforated drainage pipe" french drain preventing soil sediment infiltration.
  • Soil silt and sediment contaminated ground water is filtered through the gravel bed where soil and sediment settles at base of gravel bed 4" below french drain allowing filter water to percolate through the french drain perforations wrapped with filter fabric.
  • Foundation waterproofing protected with drainage panels and the correct french drainage system reduces hydrostatic pressure created by below grade saturated soils conditions.

Drainage Panels Outline The Future Concrete Step Profile

  • Drainage panels allows below grade ground water to flow freely through the geo textile filter fabric.
  • Drainage panels applied over foundation waterproofing and footing detail allows for water to flow to reservoir below the top of footing elevation.
  • Allows water to percolate into french drain weep holes discharging at curb or sump pump location.
  • Schedule 40 perforated drain pipes resists deflection, cracking due to the increased stress of french drain joint connections.
  • The increased stress to french drain joint connections in step footing installations require commercial grade schedule 40 perforated french drains to prevent cracking due to increased stress.

Warning!

  • Flexible perforated drain pipe set on gravel bed will not maintain a level position flush with top of footing.
  • Flexible drain will settling in gravel bed creating low dips allowing standing water and soil sediment to accumulate affecting gravity water flow and drainage.

Clay Soils Require Extending Gravel Bed To Finish Grade

  • Clay soils are expansive when saturated after rain resulting in elevated hydrostatic pressure on foundation
  • Hydrostatic pressure on foundation can cause small hairline foundation cracks to expand further damaging foundations.
  • Gravel base extending from french drain to finish grade elevation creates a buffer between the expansive clay soils and the foundation
  • Drainage panels over foundation waterproofing will protect membrane from gravel base extending to finished grade
