Views Read Edit View history. Geomembranes are made from relatively thin continuous polymeric sheets, but they can also be made from jdpe impregnation of geotextiles with asphaltelastomer or polymer spraysor as multilayered bitumen geocomposites. 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.

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.

Geomembrane – Wikipedia

The characteristics of the seamed area are a function of the type of geomembrane and the seaming technique used. These raw materials i. Continuous polymer sheet geomembranes are, by far, the most common.

There are several mechanical properties to track in monitoring such long term degradation: This reorganization results from an input of energy that originates from either thermal or chemical processes. There are a number of mechanical tests that have been developed to determine the strength of polymeric sheet materials.

Obviously, many of the physical and mechanical properties could be used to monitor the polymeric degradation process. There are a number of potential concerns in this regard.

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

Geomembranes have been used in the following environmental, geotechnical, geotechnica, transportation, and private development applications:.

These processes may involve the addition of additional polymer in the area to be bonded. 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.

Geomembrane

Projections for future geomembrane usage are strongly dependent on the application and geographical location. Geomembranes dominate the sales of geosynthetic products, at 1. Geomembranes degrade slowly enough that their lifetime behavior is as yet uncharted.

Many have been adopted for use in iin geomembranes. 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.
