Geosynthetics and
Geomembranes:
11th September 2012, 2nd Hamburg Water Forum for the EMA Region
Use of Modern Building Materials in the Waste Water
Treatment Plant, in Irrigation Systems and in Agriculture
in the EMA Countries.

Geosynthetics and Geomembranes
PRODUCT FAMILY
Geosynthetics products as manufactured by GSE include:
• GEOMEMBRANES (Flexible Membrane Liner, FML)
• GEOTEXTILES (Nonwovens)
• DRAINAGE GEOCOMPOSITES (HDPE core + Nonwoven)
• GCL‘S (Bentonite encapsulated between Woven/Nonwoven).
The raw material we mainly use is HDPE
(High Density Polyethylene), a polymer that is well known since
40 years, thorougly tested, and that is nowadays primary
source for engineered applications in water containment.

Geosynthetics and Geomembranes
Conventional Containment Design vs. Design with Geosynthetics
• Waste Water Ponds:50cm thick compacted clay barrier, or
concrete
• Irrigation Water Reservoirs: 20cm thick concrete or asphalt layers
• Irrigation Canals:clay, asphalt, or concrete
• Evaporation Ponds:clay or concrete

Why HDPE Geomembranes?
Geomembrane …. – Properties
- Cost
Compared with conventional construction materials, but also
when compared w/ alternative containment barriers, such
as PVC or EPDM (Hypalon) the HDPE geomembrane offers
distinct advantages (ref. „Design with Geosynthetics“; RAPRA).
• Durability (UV-resistance, liner can be left exposed!);
• Chemical Resistance;
• Mechanical Properties / Robustness;
• Size (minimizes field seaming works);
• Biological Resistance (to roots, plants, gnawing animals)
• Price /Availability.
