AQUICLUDE WITH GEOSYNTHETIC
CLAY LINER
Q: We are trying to design and construct
an aquiclude with a geosynthetic clay liner
(GCL). Do you have any experience with this
application where a GCL has been used as the
impervious barrier between a flowing stream
and the underlain geologic formation?
A: I have not heard of a GCL being used
alone in this application. I have heard of a
geomembrane-GCL-GM sandwich being used
in such a case. It was over a relatively small
area, about 8 acres (3.2 ha), in Maryland near
the Pennsylvania border just off I-95. Maryland
Department of Transportation used it to assist
with problems from artesian water near an onramp
with shallow foundations with success.
SPECIFICATION FOR EIA
Q: I have an upcoming project that will
use ethylene interpolymer alloy (EIA). Is
the Geosynthetic Research Institute (GRI)
working on a specification for this material?
A: Nice to hear from you and thanks for your
Techline question. We have been working on
this subject for a long time. GRI-draft GM34
standard specification revision 4 is our latest
effort on EIA. Please note it has not passed
review of the Geosynthetic Institute (GSI)
membership yet. If you have comments or
suggestions on the draft specification, we
would appreciate hearing from you. See more
on this specification on p. 40.

CSI CODE FOR GEOSYNTHETICS
Q: What is the CSI code for geosynthetics?
A: Originally founded in 1948, the
Construction Specifications Institute (CSI)
is a United States national association of
more than 8,000 construction industry
professionals who are experts in building
construction and the materials. It is the
founding institution for organizing and
coding specifications related to construction
projects. The CSI is the organization
that publishes the MasterFormat, which
is the guiding numbering system to
create consistency when comparing bids
as well as organizing all construction
documents and contracts. This publication
is the specifications-writing standard
for most of today's construction and
commercial building design projects in
North America. The MasterFormat can
be purchased at www.csiresources.org/
standards/masterformat. CSI codes, lists
Geosynthetics (310519) with subsections
for Geomembranes (310519.16), Geogrids
(310519.19) and Geosynthetic Clay Liners
(GCLs) (310519.23).
