The manufacturing of geomembranes begins with the production of the raw materials, which include the polymer resin, and various additives such as antioxidants, plasticizers, fillers, carbon black, and lubricants (as a processing aid). These raw materials (i.e., the "formulation") are then processed into sheets of various widths and thickness by extrusion, calendering, and/or spread coating.
The US market is currently divided between HDPE, LLDPE, fPP, PVC, CSPE-R, EPDM-R and others (such as EIA-R), and can be summarized as follows:[citation needed] (Note that M m2 refers to millions of square meters.)
high-density polyethylene (HDPE) ~ 35% or 105 M m2
linear low-density polyethylene (LLDPE) ~ 25% or 75 M m2
polyvinyl chloride (PVC) ~ 25% or 75 M m2
flexible polypropylene (fPP) ~ 10% or 30 M m2
chlorosulfonated polyethylene (CSPE) ~ 2% or 6 M m2
ethylene propylene diene terpolymer (EPDM) ~ 3% or 9 M m2

The majority of generic geomembrane test methods that are referenced worldwide are by the ASTM International|American Society of Testing and Materials (ASTM) due to their long history in this activity. More recent are test method developed by the International Organization for Standardization (ISO). Lastly, the Geosynthetic Research Institute (GRI) has developed test methods that are only for test methods not addressed by ASTM or ISO. Of course, individual countries and manufacturers often have specific (and sometimes) proprietary test methods.

Physical Properties
The main physical properties of geomembranes in the as-manufactured state are:
Thickness (smooth sheet, textured, asperity height)
Density
Melt flow index
Mass per unit area (weight)
Vapor transmission (water and solvent).
Mechanical Properties
There are a number of mechanical tests that have been developed to determine the strength of polymeric sheet materials. Many have been adopted for use in evaluating geomembranes. They represent both quality control and design, i.e., index versus performance tests.
tensile strength and elongation (index, wide width, axisymmetric, and seams)
tear resistance
impact resistance
puncture resistance
interface shear strength
anchorage strength
stress cracking (constant load and single point).

FAQ
What is geosynthetics ?

Geosynthetics form a perfect erosion control fabric used extremely widely in civil engineering to stabilize and reinforce slopes and soil under or next to roads, railways, dams, water reservoirs etc.. They can be easily applied which minimizes the time of construction, as well as they limit the resources and materials necessary.

What kinds of geosynthetics we have ?
