1. Materials.
Advantages: light weight, good overall continuity, high tensile strength, corrosion resistance, good resistance to microbial erosion, and convenient construction. Non-woven geofiber properties: small pore diameter, good permeability, soft texture, and good combination with soil.
2. Construction.
1) According to the full section of the embankment bottom width.
2) Leave enough anchorage length on each side of the embankment.
3) In order to ensure the integrity, when the lap joint method is used continuously, the lap joint length should be 0.3-0.5m. When the seam joint method is used, the bonding width should not be less than 50mm.
4) During on-site construction, the damaged material should be repaired immediately. The upper and lower joints should be alternately staggered, and the staggered length should not be less than 0.5m.
5) Try to avoid prolonged exposure and sun exposure.
