Achieved a growth rate of over 200%! Significantly improved follow-up performance against ground unevenness.
The "Need Keeper NK-800Z" is a high-stretch and high-strength synthetic fiber non-woven fabric developed for the purpose of preventing suction and washout in civil engineering works such as ports and land reclamation. By using special polyester fibers, it exhibits ultra-high stretch characteristics that can follow significant unevenness. Additionally, it has elasticity and excellent impact resistance, making it difficult to tear even against protrusions such as riprap and crushed stone. 【Features】 ■ Excellent chemical resistance and corrosion resistance, allowing for long-term use ■ Flexible and easily adheres to the construction ground ■ Superior effectiveness in preventing suction and washout ■ Capable of withstanding abrasion from soil and other materials over an extended period *For more details, please refer to the PDF document or feel free to contact us.
