*US Patent #5,788,413 - Geocomposite Membrane
- Geomembrane/clay interface shear strength increased.
- No
internal shear strength concerns.
- Geomembrane/clay always in
intimate contact - even in wrinkles.
- No
transmissivity along geomembrane/bentonite interface.
- High compression strength provides uniform
known thickness.
- Ability to always do electrical
leak surveys.
- Clay protected
by geomembrane during installation.
- Geomembrane automatically
ballasted.
- Geomembrane is
resistant to UV (compared to geotextile on GCLs).
- Geomembrane
less susceptible to installation damage than geotextile of GCL.
- One installation activity rather than two.
- Place on
walls without bentonite migration.
- Subgrade/liner shear strength can be increased with
spiked stubs/ridges.
- Welded or sliding seams.
