NEED KEEPER is a high-strength, high-strength synthetic fiber nonwoven fabric developed for the purpose of prevention of soil draw-out and scouring prevention in civil engineering construction work such as ports and land reclamation.
Features
- Due to its high tensile strength and elongation rate, it will not break easily even under high loads caused by heavy objects.
- It is elastic and has excellent impact resistance, so it will not break easily even when exposed to protrusions such as rubble and crushed stones.
- Because it is flexible, it easily adheres to the construction ground, and has great effects on prevention of soil draw-out and scoring prevention.
- Made of synthetic fiber, it has excellent weather resistance, chemical resistance, and corrosion resistance, and can be used for long periods of time.
- High-strength synthetic fiber non-woven fabric that can withstand wear and tear from dirt and sand for a long time.
Uses
- Prevention of soil draw-out for seawalls, fishing ports, etc.
- Prevention of soil draw-out on reclaimed seawall
- Uneven settlement of breakwaters and offshore breakwaters, scoring prevention
- Wave dissipation, uneven settlement of foot protection blocks, scoring prevention
