GCP Hydroduct® 220 Drainage Composite Mat 4' x 50'

Hydroduct® 220 Drainage Composite consists of a thick drainage core and high performance geotextile. Designed to collect and transport water, it is recommended for use on foundation walls, retaining walls, bridge abutments, tunnels, earth-sheltered structures and planters. It serves as a drainage composite and protection course for all Bituthene® waterproofing membranes used in vertical applications.

Advantages:

• Enhances waterproofing—eliminates hydrostatic pressure build-up
• Efficient water collector/deflector—can be used as a sandwich drainage layer between lagging and the reinforced concrete structure
• Smooth polymeric sheet—compatible with Preprufe®, Procor®, or Bituthene® membranes
• Simple convenient drainage and protection layer—serves as robust membrane protection and drainage
• Geotextile fabric filter—allows ground water to pass into the drain core while restricting the movement of soil particles
• High flow capacity—drains 17 gals/min./ft (211 L/min./m) width
• Rot proof—unaffected by permanent immersion in water, bacteria, dilute acids and alkalis
• Economical—eliminates imported aggregate drainage layers
• Studded core—allows water to flow to designated drainage collection points
