maintain contact with the soil without
wrinkles, which helps with slope stability
(Stark 2018). This characteristic depends
on the manufacturing quality control
(MQC) process and the geomembrane's
composition-primarily the density. It
is optimal for the geomembrane to act
like elastic rubber: When sunlight heats
up the film, it elongates, but at night as
the temperature drops, the tension disappears.
If the geomembrane adapts, its
service life will lengthen. Density, elongation,
tensile strength, tear strength,
impact resistance at low temperature and
volatile loss are relevant properties to
analyze at this second stage (Fabricated
Geomembrane Institute 2019; ASTM
D7176-06 2018).
Some wrinkles come not from folding
but from deviations in the profile during
the calendaring process. Wrinkles from
strong camber do not readily disappear
when the geomembrane's temperature
increases (e2 Technical Textiles 2020).
This is one of the reasons FGI included
camber as a control property in the
most recent specification (Fabricated
Geomembrane Institute 2019).
Degradation of the PVC geomembrane
can be controlled by the geomembrane's
composition and through
the manufacturing process, but these
things affect the product's cost. If the
composition and the production process
are not optimal, failures can occur
in the PVC cover: The geomembrane
