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.

- 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.
