Under the same gram weight specifications, the tensile strength of long silk spunbonded needled nonwoven geotextiles in all directions is higher than that of other needled nonwovens, and has higher tensile strength.
This geotextile has good creep performance, can maintain stable performance in long-term use, and is not easy to deformation.
Long silk spunbonded needled nonwoven geotextile has excellent corrosion resistance, aging resistance and heat resistance, and can be used for a long time in harsh environment without damage.
Its structural pores can be effectively controlled to achieve a certain permeability, which is suitable for projects that need to control water flow.
Long silk spunbonded bonded geotextile is more environmentally friendly, can be recycled and reused, and high durability greatly reduces maintenance costs.
Convenient construction, do not need complex technology and equipment, save manpower and material resources, suitable for projects in a hurry.

Non-woven geotextiles provide excellent filtration, isolation, reinforcement, and protection. They are designed to allow water to permeate through while preventing soil particles from passing, helping to stabilize weak foundations.
They are widely used in roads, railways, embankments, earth-rock dams, airports, sports fields, salt marshes, waste burying fields, and for reinforcement in retaining walls backfill.
The standard defines core mechanical and physical parameters including unit weight variation, thickness, breaking strength, breaking elongation, CBR mullen burst strength, sieve size, vertical permeability, and tear strength for grades from 100 to 800.
Yes, long silk spunbonded needled nonwoven geotextiles feature excellent corrosion resistance, aging resistance, and high-temperature resistance, allowing them to remain stable in harsh or long-exposure environments.
Under the same gram weight specifications, it has higher tensile strength in all directions, better creep performance to resist deformation, and offers a more economical, highly durable solution.
No, the construction process is convenient and straightforward. It does not require complex technology or specialized heavy machinery, which helps save manpower and material costs and speeds up project timelines.
