Geomembrane Composite Geotextile
Geomembrane Composite Geotextile is a composite material that combines geomembrane and geotextile through thermal compounding or bonding processes, and has the dual functions of anti-seepage and drainage filtration.
Product structure：
Upper layer: needle-punched non-woven geotextile (polyester or polypropylene)
Middle layer: anti-seepage geomembrane (HDPE, LDPE, LLDPE or PVC)
Lower layer: another layer of geotextile or protective layer can be configured according to needs
Geomembrane Composite Geotextile is a multifunctional material composed of anti-seepage geomembrane and drainage geotextile, which has excellent anti-seepage, puncture resistance, corrosion resistance and anti-aging properties. It is widely used in anti-seepage and drainage systems of landfills, reservoirs, roadbeds and other projects. Construction should pay attention to base treatment, seam welding and protective layer covering. It is the core anti-seepage material for environmental protection, water conservancy and transportation projects.
Main features of Geomembrane Composite Geotextile:
1. Impermeability: The geomembrane layer provides excellent anti-seepage effect, with a permeability coefficient of <10-13 cm/s
2. Drainage and filtration: The geotextile layer has good horizontal drainage and anti-filtration functions
3. Tensile strength: The warp/weft tensile strength can reach 20-100kN/m
4. Puncture resistance: Effectively protect the geomembrane layer from being punctured by sharp objects
5. Chemical corrosion resistance: Acid and alkali resistance, anti-microbial erosion
6. UV resistance: Add anti-aging agent, long outdoor service life
Application areas
- Environmental protection engineering: landfill, sewage treatment pool, hazardous waste disposal site
- Water conservancy engineering: reservoir, channel, dam anti-seepage
- Transportation engineering: waterproofing of highway and railway roadbeds
- Mining engineering: anti-seepage of tailings ponds and heap leaching sites
- Construction engineering: waterproofing of basements and roof gardens
Construction points
1. The base should be flat and free of sharp objects
2. The laying should be moderately loose to avoid stress concentration
3. The joints should be treated with hot welding or special adhesives
4. The protective layer should be covered in time after laying
Precautions
- Avoid construction at extreme temperatures
- Avoid direct sunlight during storage
- Construction workers need to wear protective equipment
- Choose products of appropriate specifications for different projects
