Geotextile Bag
1.Efficient Construction & Cost Savings
Direct pumping of mortar/concrete eliminates formwork, improving efficiency by 3-5x.Deployable in challenging terrains (underwater, steep slopes, etc.).
2.High Erosion Resistance
Woven geotextile with tensile strength ≥50 kN/m, withstands water flow ≥3 m/s.
3.Permeability & Soil Retention
Effective drainage (AOS ≤0.1mm) while preventing filler loss.
4.Durability
UV-resistant, chemical-tolerant (pH 2-12), service life >30 years.
Product Introduction:
Geotextile Bag is double-layer continuous bagged materials woven from industrial filaments such as polyester and polypropylene, and sewn and processed. They are filled with concrete or mortar, which solidifies to form plate-shaped protective blocks. The geotextile formwork bag serves as a flexible formwork, and the surface layer of the formwork fabric protects the concrete or mortar blocks.
