The 0.5mm HDPE Geomembrane, a flexible material crafted from high-density polyethylene (HDPE), is a remarkable innovation in the field of waterproofing and containment solutions. This ultra-durable membrane boasts exceptional anti-UV and anti-crack properties, ensuring long-term reliability and durability in various environmental conditions.
The anti-UV coating on the Geomembrane effectively resists the harmful effects of ultraviolet radiation, protecting the material from degradation and discoloration. This ensures that the Geomembrane maintains its original properties and appearance for a longer period, even in outdoor applications.
Moreover, the anti-crack formulation of the 0.5mm HDPE Geomembrane significantly enhances its durability and resistance to cracking. This allows it to withstand various stresses and strains, such as temperature fluctuations, ground movement, and chemical exposure, without sustaining damage.
The flexibility of the Geomembrane allows it to adapt to various ground contours and irregularities, ensuring a perfect fit and secure installation. This flexibility also makes it easier to handle and install, reducing labor costs and installation time.
Overall, the 0.5mm flexible material HDPE Geomembrane with anti-UV and anti-crack properties is an excellent choice for waterproofing and containment applications. Its durability, reliability, and ease of installation make it a cost-effective and efficient solution for various projects, including fish ponds, landfills, canals, and reservoirs.
1. Definition and Materials of Geomembranes：
A geomembrane is a flexible impermeable barrier made of polymer materials (e.g., HDPE, LDPE, PVC, LLDPE) with an extremely low permeability coefficient (typically ≤1×10⁻¹² cm/s). It effectively blocks the migration of liquids or gases. Its thickness ranges from 0.2–3.0 mm and is installed via thermal welding or chemical bonding to form a continuous barrier.
2. Core Applications：
1.Hydraulic Engineering
Reservoirs/Canals: Replaces traditional clay liners, reducing leakage by >90% and improving water efficiency.
Dam Reinforcement: Used with geotextiles to prevent seepage-induced failures.
2.Environmental Engineering
Landfills: Acts as a base liner to isolate leachate (per U.S. EPA standards: permeability ≤1×10⁻⁷ cm/s).
Wastewater Ponds: Prevents contamination of groundwater.
3.Transportation Infrastructure
Subgrade Protection: Mitigates moisture-induced deformation in saline or permafrost regions.
Tunnel Waterproofing: Serves as a primary barrier in composite waterproofing systems.
4.Agriculture & Aquaculture
Ponds/Irrigation Channels: Reduces water loss by 30%–50%.
Biogas Digesters: Enhances gas collection efficiency.
3. Key Advantages
1.Superior Impermeability
HDPE geomembranes achieve permeability as low as 1×10⁻¹³ cm/s, far exceeding traditional materials (e.g., clay: ~1×10⁻⁶ cm/s).
2.Durability & Chemical Resistance
UV-stabilized lifespan exceeds 50 years; resistant to pH 1–14.
3.Cost & Construction Efficiency
Rolls up to 8m wide enable rapid installation (200-500 m²/day), cutting time by 30%-60%, costs 40%–70% lower than concrete alternatives.
4.Sustainability
Reduces clay excavation damage and supports recycling (HDPE recycling rate >95%).

Why Are Geomembranes Used in Civil Engineering? (English Version)
1.Addressing Limitations of Traditional Materials
Insufficient Impermeability
Traditional materials (e.g., clay: ~1×10⁻⁶ cm/s; concrete: prone to cracking) fail to meet high impermeability standards (e.g., landfills require ≤1×10⁻⁷ cm/s).
Poor Durability
Clay layers crack under drying/freezing; concrete degrades due to chemical corrosion or frost heave, requiring costly maintenance.
2.Key Functional Advantages of Geomembranes
Unmatched Impermeability
HDPE geomembranes achieve permeability as low as 1×10⁻¹³ cm/s, blocking liquids, gases, and pollutants (critical for nuclear waste containment or chemical storage).
Environmental Adaptability
Tensile strength ≥20 MPa, elongation ≥700% to withstand ground settlement; operational range: -70°C to +80°C, suitable for extreme climates.
Lightweight & Rapid Installation
Weight is 1/100 of concrete, reducing logistics costs; mature welding techniques (dual-track fusion, extrusion) enable daily installation of 500 m² and cut the construction period by >50%.
3. Economic and Environmental Benefits
Lifecycle Cost Reduction
Initial costs are 40%–70% lower than concrete, with minimal maintenance (no leak repairs).
Landfill leachate treatment costs drop by 60% with geomembranes.
Resource Efficiency & Sustainability
Avoids clay excavation (saves 100,000 m³ clay per 1 km² project);
HDPE is recyclable (>95% recovery rate), aligning with carbon neutrality goals.
