Geomembrane – Wikipedia

Geotechnocs and Technology of Advanced Materials. They represent both quality control and design, i. This page was last edited on 29 Decemberat Geomembranes degrade slowly enough that their lifetime behavior is as yet uncharted. There are a number of mechanical tests that have been developed to determine the strength of polymeric sheet materials.

There are a number of potential concerns in this regard. Geomembranes dominate the sales of geosynthetic products, at 1.

Obviously, many of the physical and mechanical properties could be used to monitor the polymeric degradation process. There are several mechanical properties to track in monitoring such long term degradation: Any phenomenon that causes polymeric chain scissionbond breaking, additive depletion, or extraction within the geomembrane must be considered as compromising to its long-term performance.

Geomembrane

A geomembrane is very low permeability synthetic membrane liner or barrier used with any geotechnical engineering related material so as to control fluid or gas migration in a human-made project, structure, or system.

Of course, individual countries and manufacturers often have specific and sometimes proprietary test methods.

Retrieved from ” https: Geomembranes are made from relatively thin continuous polymeric sheets, but they can also be made from the impregnation of geotextiles with asphaltelastomer or polymer spraysor as multilayered bitumen geocomposites. Projections for future geomembrane usage are strongly dependent on the application and geographical location.

The fundamental mechanism of seaming polymeric geomembrane sheets together is to temporarily reorganize the polymer structure by melting or softening of the two opposing surfaces to be joined in a controlled manner that, after the application of pressure, results in the two sheets being bonded together.

Many have been adopted for use in evaluating geomembranes. The characteristics of the seamed area are a function of the type of geomembrane and the seaming technique used.

The manufacturing of geomembranes begins with the production of the raw geohechnics, which include the polymer resin, and various additives such as antioxidants, plasticizers, fillers, carbon black, and lubricants as a processing aid.

This reorganization results from an input of energy that originates from either thermal or chemical processes. These processes may involve the geotrchnics of additional polymer in the area to be bonded.

These raw materials i. Continuous polymer sheet geomembranes are, by far, the most common.

While each is material-specific, the general behavior trend is to cause the geomembrane to become brittle in its stress-strain behavior over time. Ideally, seaming two geomembrane sheets should result in no net loss of tensile strength across the two sheets, and the joined sheets should perform as one single geomembrane sheet.

Lifetime prediction methods use the following means of interpreting the data:.
