Geomembranes are impermeable membranes used in conjunction with rocks or earth to block fluid migration in man-made structures. These membranes are usually made of synthetic polymers in sheets ranging from 0.25 to 3.5 mm thick. Geomembranes are made of various materials such as EPDM (Ethylene Propylene Diene Monomer), Linear Low-Density Polyethylene (LLDPE), High-Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), and Polypropylene (PP). Due to their ability to block fluids, they can help to prevent the dispersal of contaminants, and may be used with soil liners or permeable geotextiles to create a composite lining system that provides added security. Titan uses geomembranes in an effort to minimize the effect of human development activities on the environment. They are especially important for waste containment. Our products are manufactured from highly durable materials, often with an expected lifetime of hundreds of years. They are resistant to chemicals and to wear, so that the passage of time and corrosion do not affect the integrity of the lining. Each type of geomembrane material has specific characteristics which affect installation procedures, lifespan and performance. Titan offers a variety of materials based on the specific needs of your project.
Geomembrane installation as part of the construction of a base liner system of a landfill.
Geomembranes have been used in the following environmental, geotechnical, hydraulic, transportation, and private development applications:
As liners for potable water
As liners for reserve water (e.g., safe shutdown of nuclear facilities)
As liners for waste liquids (e.g., sewage sludge)
Liners for radioactive or hazardous waste liquid
As liners for secondary containment of underground storage tanks
As liners for solar ponds
As liners for brine solutions
As liners for the agriculture industry
As liners for the aquiculture industry, such as fish/shrimp pond
As liners for golf course water holes and sand bunkers
As liners for all types of decorative and architectural ponds
As liners for water conveyance canals
As liners for various waste conveyance canals
As liners for primary, secondary, and/or tertiary solid-waste landfills and waste piles
As liners for heap leach pads

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. This reorganization results from an input of energy that originates from either thermal or chemical processes. These processes may involve the addition of additional polymer in the area to be bonded.
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. However, due to stress concentrations resulting from the seam geometry, current seaming techniques may result in minor tensile strength and/or elongation loss relative to the parent sheet. 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 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.
For the convenience of loading, the geomembrane adopts different standards according to different film thickness.Packaging standard as follow:
