High tensile strength and elongation! It does not easily break even under heavy loads.
The "Need Keeper" is a high-stretch, high-strength sand control sheet developed for civil engineering works such as ports and land reclamation, aimed at preventing suction and scouring. Made from synthetic fibers, it excels in weather resistance, chemical resistance, and corrosion resistance, making it suitable for long-term use. It has elasticity and excellent impact resistance, so it is not easily torn by protrusions such as riprap and crushed stone. 【Features】 ■ Flexible, making it easy to adhere to the construction ground ■ Significant effectiveness in preventing suction and scouring ■ High-strength synthetic fiber non-woven fabric that withstands wear from soil and sediment over long periods *For more details, please refer to the PDF document or feel free to contact us.
