High Pesrmeability 300g PP Nonwoven Geotextile Drainage Fabric Road Pavement Separates Subsoil Aggregate Layers
High Pesrmeability 300g PP Nonwoven Geotextile Drainage Fabric Road Pavement Separates subsoil aggregate layers
Drainage PP Nonwoven Geotextile Applications :
-
French Drains / Subsurface Drainage: Prevents soil migration while allowing water to flow into perforated pipes.
-
Landfill Leachate Systems: Filters contaminants while maintaining drainage.
-
Retaining Wall Drainage: Reduces water pressure behind walls.
-
Road & Pavement Drainage: Separates subsoil from aggregate layers.
-
Erosion Control: Used in slopes and ditches to manage water flow.
Advantages Over Other Geotextiles:
-
Better Clog Resistance compared to woven geotextiles.
-
Higher Flow Rates due to random fiber arrangement.
-
Cost-Effective for filtration and separation roles.
