Details

GCP Applied Technologies (Formerly Grace) Hydroduct 660 is a high impact, creep-resistant geocomposite and protection layer for use with Grace waterproofing membranes on all horizontal applications. 

 

Product Data Sheet

 

Hydroduct 660 is a highly robust, preformed, 0.44 in. (11 mm) thick geocomposite drainage sheet system, comprising a high impact, studded polystyrene core. This is covered on one side with a nonwoven, needle punched polypropylene filter fabric and on the other side with a smooth polymeric film. This film allows the Hydroduct 660 to be placed against waterproofing membrane and should not be removed.

  • Universal horizontal application - suitable for all overburdens including concrete
  • Damage and creep-resistant—high compressive strength core resists traffic loads and site damage to maintain drainage flow
  • High flow capacity—drains 17 gal/min./ft (211 L/min./m) width
  • Enhances waterproofing—eliminates hydrostatic head build up
  • Securely bonded fabric—restricts intrusion into core
  • Polymeric backing film—compatible with both sheet and liquid waterproofing membranes
  • Lightweight—easy to install without special equipment
  •  Simple, convenient, drainage and protection layer—robust membrane protection

Hydroduct 660 Drainage Composite is designed to collect and transport water to drainage outlets. It can be used on all horizontal applications regardless of the type of overburden and serves as a combination drainage and protection course for all Grace waterproofing membranes.

The high strength, nonwoven geotextile is designed to maintain pemittivity while protecting the drainage composite from job site damage prior to, and during, the installation of the overburden. The high permittivity of the nonwoven geotextile facilitates the removal of water from a concrete.
