2mm Landfill Liner HDPE Geomembrana Para Estanques

The 2mm HDPE Geomembrana Para Estanques is a landfill liner specifically designed for pond applications. It is a synthetic liner that provides an impermeable barrier to prevent the leakage of liquids and gases, protecting the surrounding environment from potential contaminants.Offers excellent resistance to liquid and gas permeation, effectively preventing seepage and leakage. It acts as a reliable barrier to ensure the integrity of the pond liner system.

This HDPE Geomembrana is engineered to withstand harsh conditions, including temperature variations, chemical exposure, and mechanical stresses. Its durability ensures long-term performance and protection for the pond liner.

1. Introduction to HDPE Geomembranes

A geomembrana HDPE is a synthetic barrier liner made from high-density polyethylene resin. It is used to contain, isolate, or protect water, leachate, gas, or other fluids from migrating into surrounding environments. In Spanish-speaking contexts, these membranes are commonly referred to as geomembranas para estanques o rellenos sanitarios.

Core Properties:

Impermeability: Water permeability rate < 1×10⁻¹³ cm/s
Chemical Resistance: Withstands acids, hydrocarbons, and leachate
UV Stability: Carbon black added for long-term outdoor exposure
Thermal Range: Functional from −40°C to +60°C

2. Why Choose 2mm Thickness?

The 2mm thickness is ideal for heavy-duty containment systems and exposed applications. It offers a high tensile strength and puncture resistance needed in critical engineering structures like:

Class I landfills
Industrial wastewater ponds
Fish and shrimp farming ponds (estanques)
Mining tailing storage

🛡 2mm HDPE is widely recommended where mechanical stress, liner longevity, or fluid aggressiveness are significant design considerations.

3. Engineering Applications

🔹 Landfill Liner Systems

In sanitary landfills, a 2mm HDPE geomembrane acts as the primary barrier layer, placed over compacted clay or a geosynthetic clay liner (GCL) to prevent leachate migration.

🔹 Estanques / Ponds

Used for irrigation reservoirs, fish/shrimp ponds, or rainwater harvesting tanks:

Prevents seepage into subsoil
Maintains water quality
Resists microbial growth and UV exposure

🔹 Mining and Industrial Lagoons

2mm liners are used under heap leach pads, evaporation ponds, and chemical waste storage basins.

5. Installation Procedures

Proper installation is critical to ensure impermeability and system performance. Only certified technicians and approved equipment should be used.

Key Installation Steps:

Site Preparation: Grade and compact the subgrade (≤10% slope)
Panel Deployment: Unroll HDPE geomembrane using mechanical spreaders
Seaming: Use hot wedge or extrusion welding (dual-track weld preferred)
Testing: Conduct air channel pressure test and vacuum box test on seams
Anchoring: Use anchor trenches or concrete ballasts to secure edges
Protection Layer: Add geotextile or soil cover if required

⚠ Avoid stretching or folding the membrane during installation.

6. Compliance with Global Standards

🏗 International Norms & Regulations

Standard	Application
ASTM D5885	Seam strength test
GRI-GM13	Specification for HDPE geomembranes
ISO 10319 / ISO 9863-1	Geosynthetics mechanical properties
CQA/QC (EPA/Europe)	Construction quality assurance/control

Note: Municipal and environmental agencies often mandate certified materials with traceable batch numbers and lab test results.

7. Case Study: Industrial Pond in Chile

Project: 18,000 m² shrimp farming pond
Location: Valparaíso, Chile
Material: 2mm smooth HDPE
Outcome:

No leakage observed in 6+ years
Temperature resistance up to 48°C
Zero UV degradation (based on surface oxidation test)

8. Frequently Asked Questions (FAQ)

Q1: Can 2mm HDPE be used without a protective layer?
Yes, but only in conditions with no sharp rocks or heavy mechanical load. Otherwise, add a geotextile cushion layer (≥200 g/m²).

Q2: How long will the liner last?
If buried, the life expectancy exceeds 50 years; if exposed, UV-protected geomembranes can last up to 20–25 years.

Q3: Is textured HDPE necessary for pond applications?
Not always. Textured liners are mostly used on slopes >1:3 or where interface friction is needed.

Q4: Is it food-safe for aquaculture ponds?
Yes, most HDPE geomembranes used for estanques are non-toxic, BPA-free, and inert under typical farming conditions.

9. Actionable Steps for Procurement
