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.
Yixing Shenzhou 400g Non-Woven Polypropylene Geotextile Advantage :
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
Trackbed stabilization

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.
