Needle-punched geotextile for hydraulic engineering
Needle-punchedfor hydraulic engineering is manufactured from polyester (PET) or polypropylene (PP) staple fibers through processes including fiber opening, carding, cross-laid web formation, and high-density needle punching, creating a three-dimensional interconnected structure. With superior permeability and filtration efficiency, it prevents soil erosion by trapping particles while efficiently draining seepage water to mitigate hydrostatic pressure and structural damage. By isolating soil layers and enhancing shear resistance through fiber-soil interaction, it reinforces the stability of canals, dams, reservoirs, and slopes. Resistant to chemical corrosion and microbial degradation, Nonwoven Material Supplierensures long-term durability in harsh hydraulic environments. Applied in riverbank protection, culvert drainage, and anti-seepage liners, it extends infrastructure service life by over 20% with reduced maintenance demands.

Applications
Structural Layer SeparationIsolates material layers in foundations/walls, prevents soil/aggregate mixing, and maintains layer integrity.
Independent DrainageFunctions as structural drainage to expel seepage/pore water, preventing waterlogging-related subsidence.
Slope & Erosion DefenseCombats hydraulic scouring on embankments/retaining walls, ensuring structural durability.
Filtration InterfaceUsed in drainage systems to filter soil particles while allowing water passage, preventing blockages/soil loss.
Ecological Base LayerSupports vegetation growth in wetlands/shorelines through stabilized substrate, promoting ecological stabilization.
