- What are the typical roll dimensions of Poly-Flex geomembranes?
All Poly-Flex rolls are 23 feet wide. The roll lengths range from 300 feet up to 1,550 feet depending on the material type and thickness. The gross weights are approximately 3,500 lbs. Please refer to the Material Specification Section.
- Can I purchase the liner and install it myself or do I have to go through a dealer?
Installation of Poly-Flex liners requires trained technicians and special equipment. Therefore, we highly recommend that Poly-Flex liners be installed by an experienced Dealer.
- How are Poly-Flex geomembranes shipped?
Poly-Flex rolls are shipped by flat-bed trailer trucks. Open- or closed-top containers are used for overseas shipping. Up to 12 full rolls can be shipped per truckload or container.
- Are Poly-Flex liners available in any other colors than black?
Yes. Poly-Flex liners are available in white/black. For other colors contact Poly Flex, Inc.
- Are there any limits on the project size?
No. The project size could vary from a few hundred square feet to millions of square feet of geomembrane.
- What are the advantages of Poly-Flex textured liners?
The Poly-Flex textured geomembranes are specifically manufactured with rough surfaces to produce a high interface friction angle when in contact with soils or other geosynthetic materials. This provides a high factor of safety against sliding failure on side slopes.
- What are the advantages of LLDPE over PVC geomembrane?
The advantages are as follows:
- LLDPE has resistance to a wider range of chemicals as compared to PVC.
- LLDPE is immune from biological attack by microorganisms. Microorganisms could attack PVC and use the plasticizer as a source of food.
- LLDPE is resistant to burrowing animals, PVC is not.
- LLDPE has a lower permeability to methane than PVC.
- LLDPE has a lower moisture vapor transmission rate than PVC.
- LLDPE retains its physical properties due to long-term soil burial. PVC's physical properties diminish in time due to loss of plasticizer.
- LLDPE is resistant to ultra-violet light, PVC is not.
- LLDPE remains flexible at temperatures well below freezing at -25°C. PVC loses its flexibility and becomes brittle at -25°C.
