Layfield Environmental Systems: Geomembrane Lining Materials for Aquaculture

We at Layfield Environmental Systems recognize the special needs of the aquaculture industry. Viable lining systems for this application represent a considerable capital investment. You want durable liners that will give a long service life with LOW MAINTENANCE requirements. When repairs are necessary, you want them to be easily achieved. Aquaculture liners are heavy activity centers. They get personnel traffic, filled and emptied, pressure washed and sterilized much like any other industrial food surface.

Our mission is to provide the most effective lining alternatives at the lowest operating cost to you. Our vision is in the long term of your liner. You will save with our systems. Your phone calls will be for more orders, not to address problems.

Typically, we recommend potable grade reinforced polypropylene liners for this application. Our polypropylene liners consist of "clean" polymers that impart nothing into the water. They are engineered to be used in potable applications and endure weather with product warranties up to 20 years. Our potable grade liners are certified to meet National Sanitation Foundation Standard 61 compliance requirements for potable applications.

We can also provide Hypalon^Ž, HDPE, EPDM and PVC liners.

When evaluating liners for this application, it is important to investigate the following aspects:

Is there sufficient puncture and abrasion resistance for a long service life in such an environment?

Reparability. Can effective long-term repairs be made inexpensively and without the need to mobilize personnel with special equipment?

How viable are the field joints? Lining systems almost always require field seaming. If the seaming can only be done using a tape, this will not be a viable bond over time. It is important to choose a material that can be seamed or repaired using heat and/or chemicals giving bonds at least 75% as strong as the liner material itself.

Is the material suitable for food grade applications? Does it have resistance to cleaning agents?

Is the material resistant to microbial attack from both soil and water borne sources?

Is the material suitable for soil burial and/or direct contact with sunlight?

Is the material suitable for foot traffic? Is it slippery before it’s even wet?

Are long term warranties available?

We can assist you in specifying a lining material and answer all of these questions for you.

We would be happy to address any inquiries that you have about lining systems. Layfield Environmental Systems also fabricates and installs storage tanks and elevated wall reservoir systems.
