Materials

Liner Material Expertise

HDPE (High-Density Polyethylene)

30-100 mil

The gold standard for chemical resistance and long-term containment. Ideal for landfills, mining operations, and industrial applications where chemical exposure demands maximum impermeability.

Superior chemical resistance
UV stabilized formulations
Highest tensile strength
30-100 mil thickness range

LLDPE (Linear Low-Density Polyethylene)

20-80 mil

Superior flexibility and elongation make LLDPE the preferred choice for uneven subgrades and applications requiring conformability without sacrificing containment performance.

Excellent flexibility and elongation
Conforms to uneven subgrades
Superior stress crack resistance
Ideal for settling environments

PVC (Polyvinyl Chloride)

20-60 mil

Highly conformable liner material that excels in complex geometry applications. PVC liners are factory-fabricated to large panel sizes, reducing field seaming and installation time.

Excellent conformability
Large factory-fabricated panels
Reduced field seaming
Complex geometry applications

RPP (Reinforced Polypropylene)

30-60 mil

Reinforced scrim construction provides exceptional puncture and tear resistance. The material of choice for biogas covers and applications requiring high dimensional stability.

Reinforced scrim construction
High puncture resistance
Excellent dimensional stability
Preferred for biogas covers

FAQ

Frequently Asked Questions

A geosynthetic liner is a synthetic membrane — typically made from HDPE (high-density polyethylene) or LLDPE (linear low-density polyethylene) — used as an impermeable barrier for containment applications. These engineered membranes prevent liquids, gases, and contaminants from migrating into soil and groundwater. EFI installs geosynthetic liners for agricultural lagoons, landfills, mining operations, industrial ponds, and municipal wastewater systems across 25+ states.

HDPE liners can last 50+ years with proper installation and favorable conditions. Buried liners protected from UV exposure routinely exceed 50 years of service life. Exposed liners with UV stabilizers typically provide 20-30+ years depending on climate and chemical exposure. EFI's IAGI-certified installation practices and rigorous quality assurance program ensure maximum service life from every liner system.

Liner thickness ranges from 30 mil to 100 mil depending on the application, regulatory requirements, and site conditions. Agricultural containment typically requires 30-60 mil. Landfill and municipal applications often require 60-80 mil. Mining and hazardous waste containment may require 80-100 mil. EFI's engineering team evaluates your specific regulatory framework, chemical exposure, and loading conditions to specify the optimal thickness.

Geosynthetic liner installation typically costs $0.50 to $3.00 per square foot depending on liner thickness, material type, site terrain, and project complexity. Thinner agricultural liners on prepared subgrades fall at the lower end, while thick HDPE installations on difficult terrain with extensive QA requirements are at the higher end. EFI provides detailed proposals after a free site assessment that accounts for your specific conditions.

Yes, geosynthetic liners can be repaired in the field using extrusion welding techniques. EFI's repair services address punctures, tears, and seam defects using material-compatible patching and welding methods. For localized damage, field repairs restore full containment integrity. For extensively damaged liners, EFI can install a complete relining system over the existing liner, often without removing the original material.

HDPE (high-density polyethylene) is rigid with superior chemical resistance, making it ideal for landfills, mining, and industrial applications where chemical exposure is a primary concern. LLDPE (linear low-density polyethylene) is more flexible with better puncture resistance and elongation, making it preferred for uneven subgrades, settling environments, and applications requiring conformability. EFI's engineering team recommends the optimal material based on your specific site conditions and containment requirements.
