Foundation waterproofing drainage panels

Why are drainage panels necessary?

• Drainage Panels: Relieves hydrostatic pressure to below grade foundations, basements, crawl space
• Rain Runoff: Roof gutters and down spouts can pour hundreds of gallons of water saturating the soil against your foundation creating hydrostatic
• 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
• 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

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
• 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

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.

• 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”.
