The types of thermal field seaming techniques used to construct geomembrane seams include the following: Hot Air—This technique introduces high-temperature air or gas between two geomembrane surfaces to facilitate melting. Pressure is applied to the top or bottom geomembrane, forcing together the two surfaces to form a continuous bond. Geomembrane liners are a common component in waste containment systems. Their performance is directly related to the quality of seams in the liner. The objective of this paper is to develop a probabilistic model of geomembrane seams to design and analyze destructive testing programs for quality assurance and quality control (QA/QC).

At present, the methods described in this paper are commonly used. Future technology will need to be devised to permit simpler, more effective seaming, with less opportunity for weaknesses to be induced in the liner membrane.

Koerner, Arthur E. Lord. Geomembrane inspection in installation projects are not only required by the authorities, but is a vital part of maintaining a successful cell in both the short and long run.

The proper monitoring and recording of every deployed panel, each welded seam, all necessary repairs and the adequate inspection of air, vacuum and spark test, are the. Custom Factory Fabrication of Geomembranes Taking certain steps in the fabrication process can help your project progress more smoothly on the job site.

Fabrication of flexible geomembrane liner eliminates up to 80% of field seaming, resulting in less construction time. Automated Inspection System Splice rolls together and inspect material simultaneously. This automated inspection system will remove bad material, splice back together and then c-folds for easy material handling.

The product is then folded in half and rewinded making a compact size product for reduced in-field installation labor. welds is 5% of the sheet thickness, per the EPA’s technical guidance document, Inspection Techniques for Fabrication of Geomembrane Field Seams.

The Geomembrane Guide is a comprehensive guide to products, services and applications for all members of the Fabricated Geomembrane Institute (FGI). The products are organized into the five categories below. Each product has a link to the manufacturer's website and specification sheets.

Geomembranes are relatively impermeable planar materials sheets that are shipped either as rolls or folded panels. The panels may be seamed in a factory or in the field. This guide provides geomembrane users with the most appropriate seam evaluation techniques for the most common geomembrane materials available on the market.

It was shown that the real-time inspection for detecting faulty area was possible by taking thermal images of the seams while the sheets were welded by a self-propelled heat-welding machine.

This method is more efficient compared to the conventional inspection method as that the seam can be examined with the welding : Hirofumi Nakayama, Takayuki Shimaoka, S. Ueda.
