Polypropylene

Content

Polypropylene geomembranes excel under the most demanding conditions. They are lightweight, allowing flexibility to fabricate large panels, while minimizing field seaming. This leads to significant quality and cost benefits. Polypropylene geomembranes are available reinforced and nonreinforced in thicknesses ranging from 20 mils to 100 mils. Manufactured in black, tan and white with custom colors available.

Advantages:

  • Flexibility
  • Puncture Resistance
  • Chemical Resistance
  • Dimensional Stability
  • Seaming Characteristics
  • Plasticizer & Chlorine Free
  • Heat Weldability
  • High Tear & Tensile Strength
  • UV & Ozone Resistance
  • Does Not Crack Under Environmental Stress
  • Resistant to Aggressive Liquids, Wastes, & Chemicals
  • Potable & Industrial Grades Available

Reinforced Polyproylene:
Reinforced Polpropylene is a light-weight material reinforced with a polyester scrim and can be used to build large panels up to 25,000 square feet in a factory setting to install in the field. Reinforced Polypropylene is designed for UV stability in exposed liner and floating cover applications, and it is flexible to form fit reservoirs, tanks, and lagoons. It even retains its flexibility in cold weather.

PVDF

Content

PVDF membranes are formulated with polyvinylidene fluoride, a highly non-reactive and pure thermoplastic fluoropolymer, generally used in applications requiring the highest purity, strength and resistance to solvents, acids and high temperatures. PVDF was designed for the chemical, safety, medical and food industries, for use in applications such as tubing, venting, ducting and containment of acids, solvents and fuels. PVDF is available in a variety of sizes and colors, with or without an encapsulated edge. PVDF can also be extruded onto various fabric and yarn types, in order to customize a unique membrane to meet the requirements of specific applications.

Advantages:

  • UV resistance
  • Flame resistance
  • High abrasion resistance
  • Excellent outdoor service life
  • High chemical resistance
  • High operating temperatures: (250°F continuous / 275°F intermittent)

EPDM

Content

EPDM is a rubber geomembrane designed to handle exposure to UV, ozone, extreme temperatures and other harmful environmental conditions. EPDM is highly resistant to cracking which leads to outstanding age stability with little or no maintenance.

Advantages:

  • Extreme Flexibility
  • Excellent Weathering Resistance
  • Fish & Plant Friendly
  • Wide Range of Applications

PVC

Content

PVC geomembranes are highly flexible, non-reinforced, cost effective liners with high puncture strength, excellent abrasion resistance and tolerant to many industrial chemicals.
PVC geomembranes are available in 20, 30, 40 and 60 mil thicknesses.

Advantages:

  • Industrial or Fish Grade
  • Custom Size Panels
  • Quick Installation
  • Numerous Applications

Geosynthetic Clay Liners

Image

Content

Geosynthetic clay liners (GCLs) combine geosynthetics with sodium bentonite clay to form a highly impermeable barrier that often replaces thick layers of expensive compacted clay. US FUSION offers two different products: a geomembrane supported GCL and a fabric encased GCL, both of which deliver reduced cost and increased performance even in the most demanding environments. GCLs are typically used in one of two fundamental capacities. First, in a bottom liner system to contain fluid (landfills, surface impoundments, and secondary containment areas). Or, in a cover system to keep fluid out (landfill caps and remediation closure applications).

Geomembrane supported GCL Advantages:

When utilitzed as a one product composite liner, the hydraulic performancel is superior to conventional goemembrane/compacted clay lining systems, given its excellent intimate contact, minimal wrinkles, and self sealing overlapped seams. When utilized in an encapsulated liner, the geomembrane supported GCL hydraulic performance results in 17,000 times less leakage when compared to conventional geomembrane/compacted clay composite liner systems. Examples of hydraulic and leakage comparisons between geomembrane supported GCLs and conventional composite liner systems for different composite liner applications can be found in the GundSeal Design Manual.

Fabric Encased GCL Advantages:

The sodium bentonite clay utilized in fabric encased GCLs is a naturally occurring clay mineral that swells as liquid enters between its clay platelets. When hydrated under confinement, the bentonite swells to form a low permeability clay liner with a hydraulic conductivity value of 5 X 10 cm/sec which is an equivalent hydraulic protection of several feet of compacted clay.
