Manufacturers' product data
specification charts

Geosynthetics magazine asked manufacturers and exclusive marketers of geosynthetic products to supply data about
the physical and mechanical properties
of products for the charts. We classified
product data according to groupings of
geotextiles, geomembranes, geosynthetic
clay liners, drainage materials, geocells,
geogrids and erosion control materials.
The magazine asked companies that
submitted product listings to provide
data according to industry-accepted test
methods. Except in the case of geomembrane and erosion control product manufacturers, we requested that all companies
provide minimum average roll values
(MARV). We required all companies to
submit a signed certificate of compliance
verifying the accuracy of their numbers.
The definition of MARV, as used in
the Geosynthetics 2021 Specifier's Guide,
is the value calculated as typical minus
two standard deviations from documented manufacturing quality-control
test results obtained from a single test
method associated with one specific
property. A MARV statistically indicates
a 95% degree of confidence (Robert M.
Koerner, Designing with Geosynthetics,
Vol. 1, 6th ed., Xlibris, 2012) that any
samples taken during quality-assurance
testing will exceed the reported value.
Geosynthetics magazine gave geomembrane manufacturers the choice
to submit geomembrane product data
as minimum values or MARV. In this
case, we define minimum as the value
calculated as the typical minus three
standard deviations from documented
manufacturing quality-control test results
obtained from one test method associated with one specific property. A minimum value statistically indicates a 99.7%
degree of confidence that any sample
taken during quality-control testing will
exceed the value reported.

We asked all companies to supply data
in System International (metric units)
and English units. We show English units
in parentheses.

Fees paid and free listings
Some companies paid fees to be listed in
the Geosynthetics 2021 Specifier's Guide.
The magazine's staff can provide information about these fees and eligibility for
next year's edition. See contact information on page 6.
Some companies received free directories listings and product data chart
lines based on advertising contracts
and/or membership in the Geosynthetic
Materials Association (GMA).
