In modern dam construction, the demand for advanced waterproofing and soil protection materials is higher than ever. One of the most effective and reliable solutions in this field is the composite geomembrane with filament geotextile for dam infrastructure. This innovative material combines the impermeability of geomembranes with the strength and durability of filament geotextiles, providing a robust barrier against seepage, erosion, and structural failure.
What is a Composite Geomembrane with Filament Geotextile?
A composite geomembrane with filament geotextile for dam use is a multilayered geosynthetic material, typically composed of high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) geomembrane laminated with one or both sides of polyester filament nonwoven geotextile. This design enhances the product's overall performance in terms of:
Seepage control
Mechanical strength
Chemical resistance
UV stability
Puncture protection
This makes it an ideal material for large-scale water retention projects such as dams, reservoirs, and canals.
