GRACE HYDRODUCT 660
Hydroduct 660 Drainage Composite consists of a nominal 10 mm (0.375 in.) thick drainage core and high performance geotextile. The high strength, non woven geotextile is designed to maintain permittivity while protecting the drainage composite from jobsite damage prior to, and during, the installation of the overburden. Hydroduct 660 is designed to collect and transport water. It can be used on all horizontal applications up to a static load of 2440 kg/m2 (500 lbs/ft2) or approximately 1.2 m (4 ft) of soil. It serves as a combination drainage and protection course for all Bituthene® waterproofing membranes.
