160kN/M Flexible Geotextile Bag Concrete Formwork Geotextile Sandbags Slope Protection
Flexible geotextile bags serve as an innovative formwork system for concrete placement in complex environments. The fabric acts as a mold, shaping the concrete while providing reinforcement through its high tensile strength.
This system is particularly suitable for underwater construction where traditional formwork is difficult to implement. The bag adapts to irregular surfaces, ensuring close contact and improved structural integrity.
Compared with rigid concrete panels, geotextile bags offer better resistance to cracking and displacement due to their flexible nature.
