Fabricated geomembranes can be used for a variety of applications including in alphabetical order: aquaculture, baffle curtains, canals, decorative ponds, deicing fluid ponds, drill pad liners for oil and gas development, exposed or floating covers, fertilizer containment, golf course ponds, hydrocarbon containment, landfill liners and covers, mine tailings ponds and heap leach pads ...
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
Containment involves geomembranes, geosynthetic clay liners, or some geocomposites which function as liquid or gas barriers. Landfill liners and covers make critical use of these geosynthetics. All hydraulic applications (tunnels, dams, canals, surface impoundments, and floating covers) use these geosynthetics as well.
Geosynthetic clay liners (GCLs) are factory manufactured hydraulic barriers consisting of a layer of bentonite or other very low-permeability material supported by geotextiles and/or geomembranes, mechanically held together by needling, stitching, or chemical adhesives. Due to environmental laws, any seepage from landfills must be collected and ...
A composite overwrapped pressure vessel (COPV) is a vessel consisting of a thin, non-structural liner wrapped with a structural fiber composite, designed to hold a fluid under pressure. The liner provides a barrier between the fluid and the composite, preventing leaks (which can occur through matrix microcracks which do not cause structural ...
Tanks listed as suitable for outdoor service are protected from UV attack by: coloring or pigmenting and/or adding internal stabilizers which preferentially absorb or dissipate the UV energy. Shading tanks from the sun will also prevent deterioration. Tanks must be free to expand or contract, avoid excessive tension on the tank.

Formvar resin has a high softening point and strong electric insulation properties. It is also very flexible, water-insoluble, and resistant to abrasion. Formvar is also halogen free. Formvar resins are combustible and can cause dust explosions. For this reason exposure to heat, sparks, and flame should be avoided.
