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.
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.
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.
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.
