Ultra Low Perm Geomembrane

Guard Your New Construction Against Harmful Vapors And Gases

Layfield’s Ultra Low Perm Geomembrane liners act as a vapor barrier system that can restrict naturally occurring gases and volatile organic compounds (VOCs) from migrating through the ground and concrete slab.

This seven-layer co-extruded barrier is made from state-of-the-art polyethylene and EVOH resins, providing unmatched impact strength and superior gas and moisture transmission resistance. Layfield’s  Ultra Low Perm Geomembrane is up to 100 times less permeable than typical high-performance polyethylene vapor retarders against Methane, Radon, and other harmful VOCs, allowing you to construct healthy and safe buildings.

What’s The Difference Between Layfield’s Ultra Low Perm Geomembrane  And Other Geomembrane Barriers?

Wide Range of Chemical Testing Completed

Tested to a wide range of VOCs, including benzene, toluene, and xylene, Layfield's Ultra Low Perm Geomembrane demonstrates the highest barrier characteristics.

Enhanced Performance Properties

EVOH is a flexible thermoplastic copolymer with excellent flex-crack resistance and very high resistance to hydrocarbons, oils, and organic solvents.

Resistance To Decay And Degradation

The EVOH film is encapsulated between layers of polyolefin film to protect it from the elements.

Additional Features

  • Superior puncture resistance
  • Odor management
  • Can be prefabricated in large panels for easy install
  • Suitable for a broad range of applications

Brownfield Remediation

Vapor Management and Geomembrane systems can help with cleanup activities at brownfield sites, where the presence of hazardous substances, pollutants, or contaminants may limit the redevelopment or reuse.

Underbuilding Liner

Install Layfield’s Ultra Low Perm Geomembrane under and around foundations to help prevent gas and moisture from entering the building, which could cause adverse health effects.

Landfill Liners and Covers

Layfield’s Ultra Low Perm Geomembrane has excellent resistance to landfill leachate and can significantly reduce the volumetric flow of chemicals and solvents into the ground.

Product Details

Layfield’s Ulta Low Perm Geomembrane is a seven-layer co-extruded geomembrane barrier with an ethylene vinyl alcohol (EVOH) core layer, designed as an excellent barrier to methane, radon, and other volatile organic compounds (VOCs).
