What is Geomembrana 2mm
Geomembrana 2mm, commonly referred to as 2mm geomembrane, is a synthetic membrane liner primarily composed of high-density polyethylene (HDPE) or other polymeric materials. With a standardized thickness of 2 millimeters, this engineering material is specifically designed to function as an impermeable barrier, preventing the migration of liquids, gases, and contaminants in various environmental and construction applications. The material’s consistent thickness offers an optimal balance between durability and flexibility, making it suitable for large-scale containment projects. BPM Geosynthetics Geomembranea 2mm have become essential components in modern engineering, providing reliable solutions for containment, isolation, and protection of environmental resources. The 2mm variant represents a robust specification within this product category, designed to withstand challenging environmental conditions and mechanical stresses while maintaining its impermeable characteristics over extended service periods, often exceeding 50 years in many applications
1.Geomembrana 2mm Specifications and Characteristics
The 2mm geomembrane possesses distinct technical specifications and physical characteristics that make it particularly effective for demanding containment applications. Manufactured from virgin HDPE resin through processes of heating, extrusion, and calendering, the material achieves consistent density and structural integrity throughout its matrix. Typically available in black, though other colors like white, blue, and green are also produced, the 2mm geomembrane comes in rolls with widths ranging from 1-8 meters (with some suppliers offering up to 12 meters) and lengths varying from 50-200 meters, allowing for efficient installation with fewer seams.
1.1Key technical characteristics include:
Exceptional impermeability with a hydraulic conductivity of approximately 1×10⁻¹⁷ cm/s, creating an essentially impervious barrier to liquids
Outstanding chemical resistance to strong acids, alkalis, oils, and various corrosive substances, making it suitable for containing hazardous materials
Remarkable temperature tolerance, maintaining functionality in extreme temperatures ranging from -70°C to 110°C
High tensile strength and resistance to environmental stress cracking, enabling it to withstand substantial mechanical stresses and ground movements
UV radiation resistance and anti-aging properties due to the addition of carbon black and specialized additives (approximately 2.5% of composition), ensuring long-term performance when exposed to sunlight
These properties collectively make the 2mm geomembrane a durable, reliable containment solution capable of performing in diverse and challenging environmental conditions over extended periods.
2.Geomembrana 2mm Application Scope
The 2mm geomembrana demonstrates remarkable versatility across multiple sectors, serving as a critical component in various engineering and environmental protection applications. Its balanced thickness provides optimal performance across these diverse applications:
2.1Environmental Protection: In landfill liners and covers, the 2mm geomembrana prevents leachate migration into groundwater systems. It also serves in wastewater treatment facilities, containment ponds for industrial byproducts, and remediation projects for contaminated sites .
2.2Water Resource Management: The material is extensively used in reservoirs, dams, and canals to prevent water seepage and conserve water resources. It also finds application in decorative water features like artificial lakes, ponds, and landscape water elements in residential and commercial developments
2.3Mining and Industrial Applications: In the mining sector, the 2mm geomembrane lines leach pads, tailings ponds, and evaporation ponds, containing potentially hazardous mining byproducts. Industrial applications include secondary containment for chemical processing areas, fuel storage facilities, and industrial wastewater treatment .
2.4Agricultural and Aquacultural Uses: The geomembrane serves as a lining material for irrigation channels and water storage ponds in agricultural settings. In aquaculture, it creates hygienic pond liners that prevent water loss and maintain controlled farming environments .
2.5Additional applications include transportation infrastructure (tunnel waterproofing, road base protection), energy production facilities (cooling ponds, spill containment), and recreational water features (golf course water hazards, swimming pools)
3.Geomembrana 2mm Role in Landfill Applications
In landfill applications, the 2mm geomembrane plays a fundamental role in modern waste containment systems, functioning as a primary barrier against environmental contamination. Engineered landfill facilities typically incorporate the geomembrane as a key component in multi-layer liner systems, where it works in conjunction with geosynthetic clay liners, drainage composites, and protective geotextiles to create comprehensive containment infrastructure .
3.1.The primary functions of 2mm geomembrane in landfill applications include
3.1.1.Leachate Containment: It creates an impermeable barrier that prevents leachate—a potentially toxic liquid formed when water percolates through waste—from infiltrating subsurface soils and groundwater resources. This protection is crucial for maintaining drinking water quality and ecosystem health in surrounding areas .
3.1.2.Gas Migration Control: While primarily designed as a liquid barrier, the geomembrane also restricts the uncontrolled migration of landfill gases (methane and carbon dioxide), which can be captured through dedicated systems for flaring or energy recovery, thereby reducing greenhouse gas emissions .
3.1.3.Long-term Environmental Protection: The material’s chemical resistance ensures it remains effective when exposed to the complex chemical composition of leachate over decades. Its robust physical properties enable it to withstand the mechanical stresses associated with waste settlement, equipment operation, and overburden pressure .
3.1.4.Regulatory Compliance: The use of 2mm geomembrane helps landfill operators meet stringent environmental regulations governing waste containment. Many jurisdictions specifically mandate the use of geomembranes of this thickness or greater in primary liner systems for hazardous waste landfills.
The installation of geomembranes in landfills follows meticulous quality assurance protocols, including seam testing using non-destructive and destructive methods to verify continuous barrier integrity. The 2mm thickness represents an optimal balance between durability requirements and practical installation considerations for these critical applications
