High-Performance Geomembranes
for Commercial Aquaculture
Engineered for Biosecurity. Manufactured to GRI-GM13 Standards.
Infrastructure Comparison:
Aquaculture Performance
Elevate your farm from traditional risk-heavy methods to a controlled, high-yield biosecure environment. Jinseed HDPE liners redefine the engineering standards of modern aquaculture.
Water Retention
High seepage loss (10%–20% daily). Requires constant groundwater pumping, leading to unstable salinity and high energy costs.
Permeability < 1×10⁻¹³ cm/s. Ensures zero seepage. Maintains precise water levels and chemical balance throughout the cycle.
Pathogen Barrier
Soil acts as a reservoir for viruses and bacteria (e.g., EMS/WSSV). Pathogens survive in mud between harvests.
100% Virgin Resin. Non-porous surface provides a total physical barrier between stock and soil-borne pathogens.
Cycle Turnaround
30–60 Days. Labor-intensive drying, tilling, and chemical soil treatment are mandatory after each harvest.
2–5 Days. Rapid pressure-wash cleaning allows for immediate restocking, effectively adding one extra harvest cycle per year.
Dissolved Oxygen
Mud and organic decay consume high levels of oxygen. Turbid water reduces photosynthetic O2 production.
Optimized Aeration. Clean bottom allows high-efficiency paddlewheels/diffusers to maintain maximum DO levels without stirring up mud.
FCR Performance
Feed is lost in mud pores, leading to waste and toxic ammonia spikes. Higher FCR increases operational costs.
Maximum Feed Accessibility. Pellets remain on the smooth liner surface. Reduces feed waste and significantly lowers the FCR ratio.
Structural Integrity
Wave action and mechanical aerators cause dike erosion, leading to pond shallowing and expensive bank repairs.
UV-Fortified Protection. Carbon black (2.0-3.0%) ensures the liner prevents all dike erosion even under extreme tropical UV exposure.
Sludge Management
Sludge mixes with soil, creating "black mud" that is toxic and difficult to remove mechanically.
Central Drain Ready. Smooth surface allows waste to be flushed to a central point for continuous siphoning during the cycle.
Yield Potential
Limited to semi-intensive densities (e.g., 20-40 shrimp/m²) to avoid total crop failure from water collapse.
Super-Intensive Ready. Supports 150-250+ shrimp/m² through superior water quality control and aeration efficiency.
Groundwater Safety
Saline aquaculture water leaches into freshwater aquifers, damaging local agriculture and ecosystems.
Environmental Seal. Total containment prevents salt-water intrusion and protects the local environment for long-term compliance.
Service Life (ROI)
Requires major reconstruction every 1-3 years. High recurring capital expenditure on earthwork.
10–20 Year Longevity. High-density polymer structure withstands chemical exposure and extreme temperatures. A one-time investment.
Optimized Material Specifications
We offer specialized HDPE and LLDPE geomembranes engineered to meet distinct topographical and operational demands.
HDPE (High Density)
Standard for large-scale industrial shrimp farms. Engineered to provide maximum tensile strength, superior UV resistance, and excellent chemical resistance against aquaculture treatments.
- Common Thickness: 30 mil (0.75mm) / 40 mil (1.0mm)
- Standards: Exceeds GRI-GM13 requirements
- Service Life: 15-20 years (buried) / 10+ years (exposed)
- Application: Ideal for flat terrain and intensive farming ponds
LLDPE (Linear Low Density)
Ideal for irregular pond shapes or areas with high settlement potential due to its superior flexibility. Offers exceptional elongation properties without sacrificing puncture resistance.
- Elongation at Break: > 800% (ASTM D6693)
- ESCR: > 2000 hours (ASTM D5397)
- Multi-axial Performance: Excellent for uneven subgrades
- Application: Ideal for uneven topographies and retrofitting earth ponds

Project FAQ & Technical Support
Expert answers to resolve your aquaculture engineering concerns before ordering.
What thickness is recommended for commercial shrimp ponds?
30 mil (0.75mm) is the global industry standard for intensive shrimp farming. It provides the optimal balance of puncture resistance to withstand aeration equipment and cost-efficiency for large-scale operations.
How do you handle shipping to the United States?
We provide comprehensive ocean freight solutions with optimized loading for 20ft and 40ft HQ containers. All rolls are securely wrapped in protective plastic, strapped on durable cores, and labeled with batch numbers for full traceability directly to your US site.
What is the expected lifespan of Jinseed pond liners?
Engineered with 2.0% - 3.0% premium carbon black and UV stabilizers, our exposed HDPE liners typically offer a service life of 10 to 20+ years depending on local climate conditions and maintenance. Buried liners can exceed 30 years.
Are the liners toxic or harmful to sensitive fish species?
Absolutely not. We exclusively utilize 100% Virgin Resin with zero recycled (PCR) content. Our materials are SGS-certified food-safe and biologically inert, guaranteeing no heavy metals or harmful chemicals leach into your farm water.
Do I need an underlayment (geotextile) beneath the liner?
If your pond subgrade contains sharp rocks, roots, or extreme irregularities, a non-woven geotextile underlayment is highly recommended. It acts as a cushion to prevent punctures and protect the structural integrity of the geomembrane over time.
Can I install the liner myself, or do I need professional welding?
While small hobby ponds can be taped, commercial-scale aquaculture strictly requires professional Dual-track Hot Wedge Welding. This ensures a seam strength of ≥ 85% of the parent sheet and allows for air-channel pressure testing to guarantee zero leaks.
Do you offer custom roll sizes to minimize on-site welding?
Yes, our state-of-the-art production lines manufacture seamless rolls up to 8 meters wide. We can also customize the roll length according to your specific pond engineering layout to significantly reduce seam numbers and lower installation labor costs.
What kind of warranty do you offer on your geomembranes?
We provide a comprehensive quality assurance warranty ranging from 5 to 10 years for aquaculture applications. This covers any manufacturing defects, premature UV degradation, or failure to meet the specified ASTM D-series technical parameters.
GRI-GM13 Standard Compliance & Production Scale
Jinseed operates with 15+ years of specialization in geosynthetic engineering. Our production process is governed by a 24-hour on-site laboratory ensuring every roll meets North American ASTM standards before dispatch.
Material Purity
Zero recycled content. We exclusively use high-molecular-weight resins (Borealis/Dow) for maximum stress crack resistance (ESCR > 500h).
Seamless Width
Wide-roll extrusion reduces on-site welding by up to 30%, minimizing potential leakage points in large-scale aquaculture ponds.
Carbon Black
Standardized dispersion ensures uniform UV protection across the entire surface, extending liner lifespan to 15-20 years in tropical climates.
