FAQ:
Q: How to choose the right geomembrane liner?
A: Consider impermeability: HDPE has the strongest impermeability and is suitable for highly polluted environments.
Consider flexibility: LLDPE and PVC are more suitable for complex terrains.
Chemical resistance: HDPE is acid and alkali resistant and suitable for the chemical industry.
UV resistance: Black HDPE has the best UV resistance.
Q: What is the construction process of geomembrane liner?
A: Foundation treatment: Clean the site to ensure that it is flat and free of sharp objects.
Laying the liner: Unfold according to design requirements to avoid wrinkles.
Welding/bonding: Use hot melt welding (HDPE/LLDPE) or adhesive bonding (PVC/EPDM).
Quality inspection: Conduct spark detection or air pressure testing to ensure no leakage.
Protective layer coverage: Lay geotextile or sand and gravel protective layer to prevent mechanical damage.
Q: How to detect the anti-seepage effect of geomembrane liner?
A: Visual inspection: Observe whether there are damage, holes or welding defects.
Spark detection (applicable to conductive geomembranes): detect tiny leaks.
Vacuum box detection: negative pressure test on welds.
Hydraulic pressure test (applicable to pools): inject water to observe leakage.
Q: How long is the service life of geomembrane liner?
A: HDPE liner: more than 50 years (under buried conditions).
Q: How to repair damaged geomembrane liner?
A: Small holes: use special patches + hot air welding or adhesives.
Large-scale damage: re-weld new membrane after cutting.
Weld crack: clean and re-weld.
