The raw material of geosynthetics is polymer. They are made from chemicals extracted from coal, oil, natural gas, or limestone, further processed into fibers or synthetic material sheets, and finally made into various products. The polymers used to manufacture geosynthetics mainly include polyethylene (PE), polyester (PET), polyamide (PER), polypropylene (PP), polyvinyl chloride (PVC), chlorinated polyethylene (CPE), polystyrene (EPS), etc. The effective pore size is defined as the approximate maximum particle diameter that can effectively pass through the geotextile. The effective pore size is a characteristic indicator of the pore size of geotextiles, and the larger the effective pore size, the smaller the total weight of soil particles passing through it. The effective pore size d90 or O90 of geosynthetic materials represents 10% of the total weight of soil particles passing through this particle size
