Staple Fiber 400g PP Polypropylene Nonwoven Geotextile Railway
Separation Reinforcement
Polypropylene geotextile is a geotechnical material made of
polypropylene fiber as the main raw material.
Classification: There are mainly woven geotextiles, non-woven
geotextiles, geomembranes, and composite geotextiles. woven
geotextiles are further divided into woven geotextiles and knitted
geotextiles.
Yixing Shenzhou 400g Non-Woven Polypropylene Geotextile Advantage Production Methods
Spunbond: Polypropylene particles or powder are melted and fed into
an extruder. They are then spun through a spinneret into continuous
filament bundles. These bundles are then processed to create an
irregularly arranged fiber web. This web is then mechanically
reinforced by heat pressing, adhesive bonding, or needle punching
to form a continuous, uniform geotextile.
Staple Fiber Needlepunch: Short fibers are carded or opened to form
a web. The fibers are then randomly arranged by cross-laying or
air-laying, and then needle punched to entangle them, forming a
nonwoven fabric. This fabric is suitable for producing thick
geotextiles.
Features: It has excellent air and water permeability, effectively
intercepting sand and soil loss, and has excellent water
conductivity, forming drainage channels within the soil. It
enhances the soil's tensile strength and deformation resistance,
dissipates concentrated stress, and prevents mixing of upper and
lower layers of sand, gravel, soil, and concrete. The mesh is
non-clogging, highly permeable, corrosion-resistant, lightweight,
and easy to install.
Specifications of PP Polypropylene Nonwoven Geotextile:
- Weight per unit area typically varies between 6% and 8%.
- Thickness typically ranges from 0.9mm to 5.0mm and above.
- Breaking strength ranges from 2.5kN/m to 25.0kN/m and above.
- CBR bursting strength ranges from 0.3kN to 4.0kN and above.
- Equivalent pore size ranges from 0.07mm to 0.2mm.
- Vertical permeability coefficient ranges from K×(10⁻⁹-10⁻¹¹) cm/s
(K=1.0-9.9).
400g Polypropylene Non Woven Geotextile Application & Function :
Hydraulic Engineering: Geotextiles can be used for dam slope
protection and filtration, as well as reservoir seepage control.
For example, coastal defense projects in the Netherlands and
upstream slope protection of earth-rock dams in the United States
have extensively utilized geotextiles, effectively preventing soil
erosion and protecting dam safety.
Highway and Railway Engineering: Geotextiles can enhance roadbed
stability, reduce rutting deformation, prevent and suppress
reflective cracking, and delay fatigue damage. They can also
steepen highway slopes and reduce construction earthwork. my
country's railway department began using geotextiles to treat
roadbed slurry damage in 1981.
Environmental Engineering: Geotextiles are commonly used in
landfills to prevent leakage and protect groundwater resources.
They can also be used in sewage treatment and waste gas treatment
to filter, isolate, and absorb.

INSTALLATION :
1. Pre-Installation Preparation
A. Site Inspection
Clear debris, sharp stones, and vegetation.
Grade the surface to remove unevenness (max. 5cm protrusions).
B. Material Handling
Store rolls on flat, dry ground (avoid UV exposure).
Use fabric slings or forklifts to prevent edge damage.
2. Installation Steps
A. Unrolling & Positioning
Method:
Roll out parallel to the direction of expected stress (e.g., road
traffic).
Overlap edges by 30–50cm (seams subject to movement).
Avoid:
Dragging geotextile over rough surfaces.
Wrinkles or folds (compromises soil-fabric interaction).
B. Anchoring (Temporary Fixing)
C. Seaming
D. Covering
Place fill material within 48 hours of installation.
3. Post-Installation Checks
4. Common Mistakes & Solutions
5. Special Cases
A. Slope Installation
Always install top to bottom (prevents soil slippage).
Use composite geotextile-geogrid systems for steep slopes.
B. Underwater Placement
Use sinker rolls or weighted edges.
Divers may be needed to verify alignment.
