700gram Anti Seepage Polypropylene Nonwoven Geotextile Maritime Dam Water Conservancy

   700gram Anti-seepage Polypropylene Nonwoven Geotextile  Maritime Dam Water Conservancy

Description:

PP Nonwoven Geotextile is a versatile and high - performance material that plays a crucial role in various engineering and environmental projects. It can be made from polypropylene (PP) or polyester (PET) fibers. With a wide range of weight options from 100G/M² to 1200G/M² and widths from 1m to 6m (in some cases up to 8m), it can be customized to meet different project requirements 

Production process :

The production process of polypropylene non-woven geotextile mainly includes the following steps:

‌Opening‌:

 loosen the polypropylene short fiber raw material to make it a loose fiber state.

‌Combing‌:

 comb the opened fibers to make the fibers more neat and straight, and remove impurities and short fibers.

‌Web laying‌:

evenly lay the combed fibers into a fiber net of a certain thickness and width.

‌Needling‌:

 repeatedly needle-punch the fiber net with a barb needle to make the fibers entangled and embraced

with each other to form a non-woven geotextile with certain strength and stability.

‌Consolidation and shaping‌:

 hot pressing or chemical treatment of the geotextile after needle punching to further improve the

dimensional stability and mechanical properties of the geotextile‌

Polypropylene non-woven geotextiles are widely application in the following fields:

‌1. Water conservancy projects: used for anti-seepage, anti-filtration and protection of water conservancy facilities such as dams, channels, reservoirs, etc.

‌2. Transportation projects: used for roadbeds, slopes, tunnels, etc. of transportation facilities such as roads, railways, and airports

‌3. Environmental protection projects: used for anti-seepage and isolation of environmental protection facilities such as landfills and sewage treatment

‌4. Civil engineering: used for slope protection, breakwaters and other protective structures of water conservancy projects such as river embankments and lakes

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.
