Foundation & Below-Grade Drainage

• Foundation wall drainage systems
• Basement waterproofing assemblies
• Retaining wall drainage
• Below-grade structure protection
• Designed specifically for vertical applications managing subsurface water around foundations

Hydrostatic Pressure Relief Systems

• Drainage behind foundation walls
• Gravity drain or sump-connected systems
• Water management behind waterproof membranes
• Helps relieve hydrostatic pressure buildup to prevent water intrusion and structural stress

Waterproofing Protection Layer

• Protection board over liquid or sheet waterproofing
• Backfill protection for membranes
• Drainage composite within waterproofing systems
• Acts as a barrier to help prevent membrane damage during backfill

Integrated Drainage Systems

• Used with perforated pipe drainage
• Compatible with collector drain systems
• Channels water efficiently to designated drainage exits

Common Uses

• Foundation waterproofing drainage
• Retaining wall water management
• Basement moisture protection
• Protection board for waterproof membranes
• Below-grade hydrostatic pressure relief

Polyflow® 10 is designed for vertical foundation wall applications where it:

• Relieves hydrostatic pressure by channeling groundwater to a sump or drain tile
• Protects below-grade waterproofing membranes from punctures during backfill
• Provides secondary water management when combined with Polyguard drainage accessories

Common Substrates:

• Concrete foundation walls
• Masonry block walls
• Shotcrete walls
• Insulated concrete form (ICF) systems

Installation Notes:

• Install with fabric side facing the soil to filter particles
• Connect to perforated pipe outlets or sump systems for drainage discharge
• Immediately backfill with soil, sand, or gravel once installed
