Sewage Treatment 0.5mm Thick HDPE Smooth Geomembrane Waterproof Corrosion Resistance
Yixing Shenzhou Sewage Treatment HDPE Geomembrane
HDPE geomembrane is a reliable, durable, and cost-effective lining solution for anti-seepage and waterproofing. Its combination of impermeability, strength, and chemical resistance makes it an essential material for environmental protection, water conservation, mining, petrochemical, and agricultural projects worldwide.
Advantages of HDPE Geomembrane
1.Excellent Impermeability – Very low permeability, making it one of the best materials for anti-seepage and waterproofing.
2.High Chemical Resistance – Withstands acids, alkalis, salts, oils, and many organic solvents, suitable for harsh environments.
3.Strong Mechanical Properties – High tensile strength, tear resistance, and puncture resistance ensure durability.
4.UV & Weather Resistance – With carbon black and UV stabilizers, it resists sunlight, oxidation, and aging for long service life.
5.Durability – Service life of 20–50 years depending on thickness and exposure conditions.
6.Environmental Safety – Non-toxic and safe for drinking water and aquaculture applications.
7.Cost-Effective – Provides long-term protection, reduces maintenance costs, and prevents environmental damage.
8.Flexible Application – Can be used in landfills, reservoirs, canals, ponds, mining, tunnels, and more.
How to Use HDPE Geomembrane?
Prepare → Deploy → Weld → Test → Anchor
Prepare – Clean and level the ground, remove sharp objects, add geotextile if needed.
Deploy – Unroll and position the geomembrane on the surface.
Weld – Overlap sheets and join with hot wedge or extrusion welding.
Test – Check seams with air, vacuum, or spark testing to ensure no leaks.
Anchor – Fix edges in trenches or cover with soil/sand for protection.
Practical Tips
Install during calm weather (avoid strong winds).
Keep the geomembrane clean and dry before welding.
Only trained technicians should operate welding equipment.
Store rolls in a shaded area to prevent UV damage before use.
