1. Material Inspection & Storage Quality Check: Verify geotextile specifications (weight, tensile strength, CBR puncture resistance) per project requirements (e.g., ASTM D4632, GB/T 17639-2008). S
Material Selection Choose UV-resistant, high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) geomembranes for long-term durability. Ensure the material is non-toxic and safe for
Introduction Slope instability and erosion are major challenges in civil engineering, landscaping, and environmental restoration. Traditional methods like concrete retaining walls or riprap can be cos
Seepage Prevention: In projects such as earth-rock dams and levees, waterproof geotextiles can effectively prevent water seepage, reduce seepage damage, and improve the stability of dams and levees. F
1. Site Preparation DO: ✔ Laser-level subgrade to 1-2% slope toward drainage ✔ Remove all sharp objects >3mm (roots/stones) ✔ Compact soil to 95% Proctor density DON'T: ✘ Install over frozen or
1. Construction Preparation Material Selection : Geocells with certified tensile/tear strength; well-graded permeable fillers (sandy/gravel soil). Site Layout : Survey wall alignment/elevation; establ
I. Construction Preparation Material Inspection Upon arrival, geotextiles must undergo rigorous quality checks: Verify specifications (e.g., short-fiber needle-punched nonwoven geotextiles: 300–
Landfills are essential for managing waste, but they also pose significant environmental risks, particularly through the leakage of leachate -a toxic liquid formed when water filters through waste. To
1. Project Background The [Project Location] is a region characterized by complex terrain, steep slopes, loose soil, and high precipitation levels. These conditions have led to significant slope stabi
Geotextiles are widely used in civil engineering and environmental projects for their versatility in functions such as filtration, drainage, reinforcement, and separation. However, the effectiveness o
Base Surface Treatment: Ensure that the laying base surface is solid and flat. There should be no sundries such as tree roots, rubble, and stones within a vertical depth of 25 cm that may damage the g
1, Base Preparation Prepare subgrade based on engineer's specification, remove debris and rocks. Geotextile is often recommended to separate fill materials from the subgrade. A woven or nonwoven fabri
