Staple Fiber 400g PP Polypropylene Nonwoven Geotextile Highway Separation Reinforcement

Staple Fiber 400g Polypropylene Non Woven Geotextile Highway Separation Reinforcement 

400g PP Nonwoven Geotextile is a medium-to-heavyweight geosynthetic fabric made from 100% polypropylene (PP) fibers, with a mass per unit area of 400 grams per square meter (gsm). It is widely used in civil engineering and construction projects for its strength, filtration, and separation capabilities.

 1. Excellent Filtration & Drainage – Allows water flow while
preventing soil erosion.  2.High Tensile Strength – Withstands heavy loads and harsh
conditions.  3. UV & Chemical Resistant – Long-lasting performance in
exposed environments.  4. Puncture & Tear Resistant – Ideal for road bases, landfills,
and erosion control.  5. Lightweight & Easy to Install – Reduces labor and
transportation costs.  
   
  
  

  
400g Polypropylene Non Woven Geotextile Application & Function
:  
   
1. Road & Highway Construction
 Separation – Prevents mixing of subgrade soil and aggregate base
 Filtration – Allows water drainage while blocking fine soil
particles
 Reinforcement – Distributes loads to reduce rutting and cracking  
   
2. Landfill & Waste Containment
  Protection layer for geomembranes
  Leachate collection system component
  Gas venting layer in landfill caps  
   
3. Slope & Erosion Control
 Vegetated slopes (under turf reinforcement mats)
 Channel linings for waterways
 Shoreline protection  
   
4. Railway Construction
 Ballast separation from subgrade
 Pumping prevention in soft soils

Yixing Shenzhou 400g Polypropylene Non Woven Geotextile 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.
