1. It features high material strength in tensile, tearing, bursting and puncture tolerance, better than the staple fiber geotextile of the equal gram weight. With the tensile and puncture tolerance strength of more than 2200N, it can efficiently prevent the fabric from the impact of irregular stones in pitched work; 2. Excellent extension property and rapid dispersion and transmission of stress make the load distribute uniformly; 3. Rare slippage in work resulting from the large friction coefficient; 4. Good chemical tolearance; 5. Great corrosion tolerance; 6. Aging tolerance and embedded laying ensure the working life of more than 50 years; 7. Excellent hear&cold tolerance ensures the quality unaffected under the temperature condition from 200°C to -30°C.
