Application Solutions

🗑️ Landfill Liner Protection
Challenge: Sharp rocks and debris in the subgrade can puncture the critical HDPE geomembrane liner during installation or under waste load, leading to catastrophic groundwater contamination.
Solution: Used as a protective cushion layer above and below the geomembrane, its high puncture and CBR strength absorbs localized stresses, safeguarding the liner's integrity throughout the landfill's lifecycle.
⛰️ Tailings Dam Filtration
Challenge: Fine tailings particles can migrate through drainage layers, causing internal erosion, clogging of drainage systems, and potential dam failure.
Solution: Placed at the interface of the tailings and drainage zone, the geotextile acts as a highly efficient filter. It retains fine particles while allowing pore water to drain freely, preventing internal erosion and ensuring long-term dam stability.
💧 Reservoir Seepage Control
Challenge: Water seepage through reservoir embankments can cause soil piping, internal erosion, and slope instability, compromising the reservoir's structural integrity.
Solution: Installed as a filter layer beneath the riprap or concrete armor, the geotextile prevents fine soil particles from being washed away while allowing seepage water to pass, maintaining embankment stability.
🧱 Retaining Wall Backfill Drainage
Challenge: Water accumulation behind retaining walls increases lateral earth pressure, leading to wall bulging, cracking, or even catastrophic failure.
Solution: Positioned against the back of the wall facing, the geotextile acts as a drainage medium and protective filter. It channels seepage water to weep holes or drainage pipes while preventing fine backfill particles from clogging the system.
🌊 Coastal Erosion Prevention
Challenge: Wave action and tidal forces can erode the subgrade beneath coastal armor (riprap, revetments), causing the armor to sink and fail.
Solution: Placed beneath the armor layer, the heavy-duty geotextile acts as a stable filter. It retains the underlying soil while allowing wave-induced water flow to pass, preventing subgrade erosion and ensuring long-term coastal protection.
