The "Anti-Suction Sheet FP" has a complex three-dimensional structure and inter-fiber gaps, providing a drainage effect that guides water within the layers of the sheet. 【NETIS】 Since it is primarily made of polyester cotton, it experiences almost no thermal degradation, moisture degradation, or chemical degradation in the soil, allowing for safe use. Furthermore, it possesses two composite strengths: primary strength that is very close to the soil's strength curve, and secondary strength with high elongation due to the cotton's tensile strength, which allows it to work together with the soil for separation, reinforcement, and filtration, characteristic of geotextiles. 【Construction Examples (Partial Introduction)】 ■ Stairs-type revetment work ■ Connected block revetment work ■ Cage mat revetment work ■ Multi-natural type revetment, etc. *For other functions and details, please download the PDF materials or contact us directly.

The surface protection material "Palm Eco Frame" is a slope protection frame made from natural fibers (coconut fiber + hemp) that have been processed into a honeycomb structure. The natural fiber mat excels in breathability and drainage, also functioning as a means for excess water drainage and as an air and water passage. Additionally, compared to other products, it has larger voids and openings, making it easier for root and rhizome penetration and growth. Therefore, it is ideal for greening existing concrete revetments, creating vegetation bases in waterways and ponds, and protecting the back slope during embankment reinforcement. 【Features】 ○ Registered with the Ministry of Land, Infrastructure, Transport and Tourism NETIS No. CB-040065 ○ The coconut sheets are sewn into strips and form a honeycomb shape when expanded. ○ It protects the surface layer of the embankment and returns to the soil after vegetation establishment, leaving no artificial materials behind. ○ Cell height: 10 cm; standard dimensions after expansion: 6 × 12.5 m ● For other functions and details, please contact us.
