Use
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

Safety, Storage and Handling Information
All construction products must be handled properly. Material Safety Data Sheets (MSDS) are available at graceconstruction.com and users should acquaint themselves with this information. Carefully read detailed precaution statements on product labels and the MSDS before use.
Installation
Hydroduct 660 can be placed over waterproofing
membranes, concrete or wood providing job site
conditions allow the composite to remain as
placed. Additional ballast consideration should be
given in high wind exposures. Abut all edges
tightly with the excess geotextile placed over the
adjacent roll in shingle fashion.
To secure Hydroduct 660 around protrusions,
apply Preprufe® Detail Tape around the protrusion
in a picture frame configuration. Cut Hydroduct
660 to fit snugly around the protrusion. Press
Hydroduct 660 core firmly into the Preprufe
Detail Tape.
Hydroduct 660 should be covered promptly. Do
not leave Hydroduct 660 exposed to sunlight for
more than two weeks. Motor vehicles, construction
equipment or other trades should not be
allowed directly on the Hydroduct 660.
