Geomembrane Liner Applications We Serve
No two containment projects are exactly alike. The right liner depends on what is being stored, the shape and condition of the site, expected chemical or UV exposure, and the regulatory requirements that apply. Carson Liners fabricates geomembrane liners for a wide range of municipal, agricultural, commercial, and industrial applications across California and the Western United States.
Irrigation Ponds and Water Storage
Reliable water storage is essential for farms, ranches, vineyards, and rural water agencies managing seasonal irrigation demands. A properly designed geomembrane pond liner helps reduce seepage, protect surrounding groundwater, and extend the useful life of an earthen pond or reservoir. We design liners to meet project-specific conditions and can support agricultural projects that must comply with applicable NRCS standards. Learn more about our pond liner solutions.
Wastewater Treatment Systems
Wastewater systems place demanding conditions on containment liners, making material selection especially important.
Carson Liners works with municipal treatment plants, food processing facilities, wineries, and industrial operations to select liners suited to the chemistry, temperature, and operating conditions of each project. Our geomembrane liners help contain process water, protect surrounding soil and groundwater, and support environmental compliance.
Stormwater Management
Stormwater retention and detention basins need reliable containment to limit pollutant migration and protect the surrounding water table. We fabricate geomembrane liners for municipal stormwater systems, commercial development sites, transportation projects, and other infrastructure applications where dependable containment and environmental compliance are required.
Reservoir Liners
Potable water reservoirs, fire suppression reservoirs, and municipal storage facilities require liners that meet strict health, safety, and performance standards. Carson Liners offers NSF/ANSI 61 certified materials and follows applicable ANSI/AWWA guidance for reservoir lining projects. Factory-welded seams and careful quality control help provide reliable, long-term leak protection.
Canal Liners
Unlined canals and water conveyance channels can lose significant amounts of water through seepage. A geomembrane canal liner helps reduce water loss, control erosion, and improve delivery efficiency for irrigation districts, farms, and water agencies.
Geomembrane Materials: Choosing the Right Liner
Choosing the right geomembrane material is one of the most important decisions in a containment project. Carson Liners works with multiple liner materials and recommends the best option based on your application, site conditions, chemical exposure, UV exposure, expected service life, installation needs, and budget. View our complete material specifications or visit our material selection guide for more detail.
HDPE Geomembrane (High-Density Polyethylene)
HDPE remains one of the most widely used geomembrane materials because it offers excellent chemical resistance, low permeability, and cost-effective performance for large-scale containment. HDPE geomembrane liners are a strong choice when chemical exposure and impermeability are primary concerns. Because HDPE is more rigid than reinforced alternatives, installation can be more challenging on sites with complex shapes or irregular slopes.
- Best for: Industrial containment, large ponds, environmental remediation
- Chemical resistance: Excellent
- UV resistance: Good (with carbon black formulation)
- Typical lifespan: 20-30+ years
- Relative cost: Low-moderate
RPE (Reinforced Polyethylene)
When a project requires a lightweight liner without sacrificing strength, reinforced polyethylene (RPE) is often an excellent choice. RPE combines polyethylene with a woven reinforcement layer to create a strong, durable geomembrane. Its high strength-to-weight ratio allows us to fabricate very large panels, which can reduce field seaming and speed installation. In many applications, RPE can also be installed without an underlayment, helping lower total project cost.
- Best for: Large irrigation ponds, reservoirs, exposed containment
- Chemical resistance: Good
- UV resistance: Very good
- Typical lifespan: 25-40+ years (warranty dependent)
- Relative cost: Moderate
RPP (Reinforced Polypropylene)
For potable water applications, Carson Liners frequently recommends reinforced polypropylene (RPP). The material can be box-welded into three-dimensional shapes with clean corners and minimal folds or wrinkles, making it especially well suited for water tank liners and precise containment geometries. NSF/ANSI 61 certified RPP options are available for drinking water contact and can provide an exceptionally long service life.
- Best for: Potable water tanks, reservoirs, box-welded applications
- Chemical resistance: Good to excellent
- UV resistance: Good
- Typical lifespan: 30+ years
- Relative cost: Moderate-high
CSPE / HypaFlex (Chlorosulfonated Polyethylene)
CSPE, now commonly marketed as HypaFlex and formerly known as Hypalon, is a premium geomembrane material valued for outstanding UV and weathering resistance. It is often selected for floating covers and exposed liner applications where long-term sun exposure cannot be avoided. Available products may carry extended weathering warranties, including 30-year options.
- Best for: Floating covers, exposed liners, extreme UV environments
- Chemical resistance: Good
- UV resistance: Outstanding (30-year warranty)
- Typical lifespan: 30+ years
- Relative cost: High
PVC (Polyvinyl Chloride)
PVC is a flexible, economical geomembrane option that is easy to handle and shape during installation. Because it has limited long-term UV stability, PVC should generally be buried or covered when used outdoors. It can be a practical choice for buried containment, plating tank liners, and budget-sensitive applications where direct sunlight is not a factor.
- Best for: Buried containment, plating tanks, budget-sensitive projects
- Chemical resistance: Moderate
- UV resistance: Poor (must be buried)
- Typical lifespan: 10-20 years
- Relative cost: Low
How Carson Fabricates and Installs Geomembrane Liners
Rather than relying entirely on field-seamed panels, Carson Liners fabricates large geomembrane liner sections in our controlled factory environment whenever project conditions allow. Factory fabrication provides more consistent quality control, reduces the number of seams completed at the job site, and can shorten installation time. Every seam is inspected and tested before the liner leaves our facility.
Our Process
- Site Assessment and Measurement. We review your site, drawings, or project specifications to confirm dimensions, substrate conditions, chemical exposure, UV exposure, access limitations, and other factors that may affect liner performance.
- Material Selection. We recommend the geomembrane material best suited to the application. Each recommendation considers chemical compatibility, anticipated service life, installation conditions, regulatory needs, and budget.
- Factory Fabrication. Your liner is fabricated to the required dimensions in our facility using controlled heat-seaming processes. Seams are inspected and tested before shipment.
- Shipping and delivery. The completed liner is carefully folded, rolled, or packaged for transport. Depending on the material and project size, large liners may ship as one or a small number of panels to reduce field seaming.
- Professional Installation. Our installation crews manage the work from site preparation through final inspection. Team members are trained in applicable CAL/OSHA confined-space and fall-protection requirements and maintain seam certifications for HDPE and reinforced materials.
