Foundation waterproofing drainage panels
Why are drainage panels necessary?
- Drainage Panels: Relieves hydrostatic pressure to below grade foundations, basements, crawl space foundations.
- Rain Runoff: Roof gutters and down spouts can pour hundreds of gallons of water saturating the soil against your foundation creating hydrostatic pressure.
- Drainage panels installed over foundation waterproofing and footing profile and provide a protection barrier to foundation waterproofing membrane.
- Foundation Drainage: Drainage panel allows below grade ground water to migrate unrestricted to footing location.
- french drains: Allows water to percolate into french drain perforations through wrapped in filter fabric, water flows to perforated drainage pipe “ french drain” sloping to discharge location.

Drainage Panels Protecting Foundation Waterproofing
Waterproofing membrane / drainage panels applied over foundation
- Drainage: french drains positioned and sloped at foundation base
- Protection:Filter fabric installed over french drains prior to covering with gravel

Gravel applied Over French drain
Rigid french drains prevent deflection necessary to provide correct drainage.
- French Drain: Positioned at footing base to prevent water build-up at foundation / footing connection
- French Drain: Installed below top of footing creates a drainage reservoir below the foundation and reduces
hydrostatic pressure to foundation membrane. - Warning: Some waterproofing contractors position french drain on top of the level footing with no sloping at all, the
required 1/8” per foot slope is necessary for gravity flow to discharge location.
Advantages of positioning drain along footing.
- Positioning: French drain along footing allows adjustments of 1/8”per foot sloping for gravity flow of below grade ground water to discharge location.
Architects specify this drainage process for new construction.

Foundation 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 slit from clogging french drains.
- Drainage: Allows below grade ground water in gravel bed to percolate through filter fabric and into french drain
perforations “weep holes”. - Protection: Filter fabric wrapped three layers around “perforated drainage pipe” preventing soil sediment infiltration
into “weep holes”.

Foundation french drain installed at footing profile
Correct sloping required to step foundation french drain installations.
- Warning: Some waterproofing contractors position french drain on top of footings raising the water table elevation
necessary for foundation drainage. - Positioning: french drain on top of footing creates higher reservoir of below grade standing water at base of footing.
- Drainage: The goal of foundation drainage is to REDUCE below grade water levels allowing water to percolate into
weep holes below top of footing. - Sloping: french drain required to conform to foundation change in elevations for effective drainage flow.
- Sheet Membrane: Application over fluid-applied polyurethane waterproofing to below grade foundation and footing.
- Drainage Panels: Installed to below grade foundation and footing for effective water drainage to french drains.
- Schedule 40: Drain pipes are recommended when numerous transitions and change in elevations are required, the
thicker pipe withstands cracking and deflection to below grade drainage.

- Moisture: Controlling slab moisture prevents mold conditions to flooring, baseboards, drywall behind baseboards
- Mold conditions: Call 1-888-650-0111
- Warranty: Manufactures foundation waterproofing warranties available

Drainage panels installed over foundation / footing waterproofing
French drain positioned at base of footing

Surface grinding light well foundation prior to waterproofing
Surface grinding creates a fine course texture to concrete allowing membrane to directly bond
- Surface Preparation: Correct surface prep prevents poor bonding issues which results in future below grade leaks
- Warning: Failing to follow manufactures guidelines for surface prep will void waterproofing membrane warranties
