Custom Geomembrane Liners and Custom Pond liners

Geomembrane Liners and pond linersETP’s geomembrane liners are suitable for a pond, lagoon, reservoir, canal, pit, landfill or tank. ETP can fabricate a primary geomembrane to contain the fluid or dry waste you want to control. We also make Secondary containment liners, which are your second line of defense and are made to control almost any contained substance. Our geomembrane liners and pond liners are fabricated to your specification and used for several environmental applications.  

Geomembrane Liners

geomembrane line installGeomembranes are industrial fabrics engineered and manufactured to protect our environment by preventing whatever material that covers them to penetrate to the ground. ETP fabricates geomembrane liners which can cover, enclose, separate, or protect the environment from toxins and environmental hazards. Our linings applications include primary or secondary containment for environmental applications.




30, 36 and 45 mil Pond Liners

The liners are most often used in the water storage market as well as in chemical containment. 

Fish Hatchery Pond Liners

Fish Hatchery Pond Liners eliminate seepage, reduce costs on construction and make it possible to have ponds anywhere.

Industrial Grade Pond Liners

(See GE Nuclear Case Study) Industrial Grade Pond Liners – The are suitable for recreational lakes, decorative ponds, water conveyance, reservoirs, oil reserve pits. Also for  caps (covers) and geomembrane liner for solid waste landfills and sanitary landfills. 

XR-3 Pond Liners – used for moderate chemical resistance requirement applications such as storm water and domestic wastewater. 

XR-5 Pond Liners – XR5 is an extremely tough woven composite fabric of polyester fibers that has been molecularly coated with sophisticated compounds that are minimally degradable in adverse environments.

GE Nuclear Case Study

***ETP installed a 45 mil PPE liner at the G E Nuclear facility in San Jose, CA for the purpose of the facility to capture and reuse their test liquids. The facility uses the water storage tank with a synthetic liner to speed up the plants turn around time for their procedures and to dramatically reduce the cost of the specialized water needed for their operations. The facility needs ionized water in their process and before the tank and PPE liner were installed the ionized water was treated and sent down the storm drain, along with a huge amount of money and time. No longer will GE Nuclear need to process ionized water, they will be able to capture and reuse their existing supply over and over again. The sixty foot diameter tank that stands twenty four feet tall with the ETP liner inside will be in service for years to come, saving time and MONEY for GE Nuclear.***


Here are some key applications and uses of geomembranes:

Landfills: Geomembranes are widely used as liners in landfills

Pond Liners: Geomembranes are used in the construction of ponds, reservoirs, and lagoons for water storage, wastewater treatment, and aquaculture.

Secondary Containment: Geomembranes are employed in secondary containment systems around storage tanks, pipelines, and industrial.

Wastewater Treatment: Geomembranes are used in the construction water treatment plants.

Our geomembranes are also used for floating covers and bio-gas containment.
