Composite Geomembrane is a combined geosynthetic material fused by geotextile and HDPE geomembrane, widely adopted in water conservancy, landfill, aquaculture and infrastructure projects for anti-seepage, isolation, drainage and protection.
Introduction
Composite Geomembrane is a multifunctional integrated liner that perfectly combines the anti-seepage property of HDPE membrane and the protection & drainage function of geotextile. It effectively stops liquid seepage, isolates pollutants and reinforces foundation structure for all kinds of civil and environmental engineering.
What is Composite Geomembrane?
It is an integrated composite material bonded by non-woven geotextile and HDPE impermeable membrane via advanced hot compound process. It integrates anti-leakage, anti-puncture, drainage, isolation and anti-aging functions in one piece, greatly simplifying construction procedures and improving overall engineering stability.
Types of Composite Geomembrane
- One cloth one film: Basic type, common anti-seepage use
- Two cloth one film: Higher strength, better protection and anti-puncture
- One cloth two film: Enhanced double-sided anti-seepage effect
- Custom compound structure: Customized ratio for special projects

Advantages of Composite Geomembrane
Dual functions of seepage prevention and protection in one material
Saves separate laying steps, lower construction cost
Effectively prevent geomembrane from being punctured by gravel
Good drainage performance to reduce water pressure damage
Strong adaptability to complex terrain and soil conditions
Long service life, low later maintenance cost
Construction & Laying Tips
Lay flat and tidy on smooth base surface, avoid sharp objects scratching. Adopt hot welding for membrane jointing and reasonable lap joint treatment. Ensure tight combination between layers, standard construction to guarantee long-term anti-seepage effect.
How to Choose Composite Geomembrane
Confirm project usage scene and anti-seepage grade demand
Select proper geotextile gram weight and membrane thickness
Judge slope gradient to choose matched friction type
Match environment corrosion degree and exposure condition
Follow local engineering standard requirements
FAQ
What is composite geomembrane used for?
Mainly used for anti-seepage, isolation, drainage and foundation protection in water conservancy, environmental protection, aquaculture and traffic engineering.
What is the difference between composite geomembrane and single HDPE geomembrane?
Composite type has extra geotextile protection layer, owns better anti-puncture, drainage and anti-damage ability, more suitable for harsh construction base.
Can it be customized?
Yes, we support customized gram weight, membrane thickness, width and compound structure according to customer project demands.
How long is its service life?
Buried use can reach 40-60 years, exposed use maintains stable performance for more than 25 years.
Conclusion
Composite geomembrane is an ideal high-efficiency geosynthetic anti-seepage material. With integrated multiple functions, stable physical property and cost-saving advantage, it has become the preferred lining material for large-scale anti-seepage engineering all over the world.
