Large Containment Liners

Liner Types & Information

Engineered for large-scale containment — geomembranes and containment liners offer durable, flexible, and chemical-resistant performance for reservoirs, oil and gas, wastewater, agriculture, and other environmental or industrial applications.

High-Density Polyethylene Liners (HDPE)

Reinforced Linear-Low Density Polyethylene (RLLDPE)

Linear-Low Density Polyethylene (LLDPE)

Why Do I Need a Reservoir Liner?

Without a liner, water can leak, soil erode, and reservoirs get contaminated. Liners protect water quality and the surrounding environment.

What Materials Are Used?

HDPE – Strong, UV-resistant, long-lasting.
Reinforced LLDPE – Flexible, tear-resistant, durable.
LLDPE – Ultra-flexible for shaping around natural landscapes.

Are Custom Sizes Available?

Yes. Liners can be cut and welded to fit any reservoir or pond size for proper coverage and efficient installation.

How Are Liners Used in Projects?

Stormwater retention, agricultural ponds for irrigation & livestock water storage.
Aquaculture & fish farms, industrial & mining ponds to maintain clean water and prevent contamination.
Wetland & habitat projects to manage water levels sustainably.
Oil and gas operations.

Who Installs the Liners?

Certified wedge welders or trained professionals ensure seams are sealed properly. Factory-made panels make installation faster and more reliable.

HIGH-DENSITY POLYETHYLENE LINERS (HDPE)

HDPE is rigid high density polyethylene geomembrane that provides
exceptional longevity and durability with great chemical resistance
and low permeability. A cost-effective choice for large and exposed
lining projects. Excellent protection from UV rays and harsh weather
conditions. Field seaming requires specialized welding equipment
and certified welding technicians. 15-year UV exposed warranty.
Only available in master rolls of 23’ widths increments
(no prefabricated sizes available)

HDPE

HDPE Thickness	Roll Length	Weight (lb per ft²)
40 mil	Up to 800'	0.20
60 mil	Up to 600'	0.30

REINFORCED LINEAR-LOW DENSITY POLYETHYLENE (LLDPE)

Reinforced LLDPE is a flexible geomembrane reinforced with a polyester reinforced scrim encapsulated between two layers of highly UV stabilized linear-low density geomembrane. Exceptional toughness, high tensile and puncture strength, and tear resistance. Excellent protection from UV rays and harsh weather conditions. Preferred for ease-of-field seaming or use factory fabricated custom size panels to save install time. Custom panels are accordion rolled onto 7’ core. 20-year UV exposed warranty.
Rolls available in 10’ Width increments and 5’ length increments.

REINFORCED LLDPE

LLDPE Thickness	Panel Size	Weight (lb per ft²)
30 mil	Up to 50,000 sq ft	0.14
45 mil	Up to 37,500 sq ft	0.21

LINEAR-LOW DENSITY POLYETHYLENE (LLDPE)

LLDPE is a very flexible linear-low density polyethylene geomembrane. Provides exceptional elongation, tensile, and impact strength. Delivers excellent protection from UV rays and harsh weather conditions. Preferred for ease-of-field seaming or factory fabricated custom size panels to save install time. Custom panels are accordion rolled onto 7’ core. 15-year UV exposed warranty.
Rolls available in 10’ Width increments and 5’ Length increments.

LLDPE

LLDPE Thickness	Panel Size	Weight (lb per ft²)
20 mil	Up to 75,000 sq ft	0.10
30 mil	Up to 50,000 sq ft	0.15
40 mil	Up to 37,500 sq ft	0.20
