Geomembrane has a broad variety of applications such as liners for potable water, liners for reserve water, liners for waste liquids, liners for waste liquids and so on. This product can be particularly used as an insulator coating for preserving and storing water for agriculture pools (fish breeding).
Waste liquids liner Reserve water liner Portable water liner


It is known as geomembrane containing silver nanoparticles. It also shows remarkable antibacterial activity compatible with ISIRI 10900. In nano-dimension, antibacterial effect of silver increases significantly, so that they are able to destroy over 650 bacterial species. It is reported that these nanoparticles have significant antifungal activities against some ringworms. Ag nanoparticles interact with sulfur and phosphorus compounds of membrane proteins affecting cell morphology and structure, causing its death. With decreasing particle size, the release of silver ions increases, leading to increasing their antibacterial activities.

Anti-bacterial Activity

Manufacturer's Description

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. That has proven to be far more effective than traditional products such as concrete, asphalt and compacted clay. It displays a wide range of physical, mechanical and chemical resistance properties protecting our environment and water resources. It is important to remark that the antibacterial effect of polymer-silver nanocomposite is preserved and good antibacterial efficiency against a wide variety of bacteria is observed. Silver ions and compounds are highly toxic for a wide range of bacteria and they show very low toxicity for human cells, so that the use of silver in different forms has been a common method for antibacterial protection.
