3. Non Woven Polypropylene Fabric Peru Application for Road Construction
The customer from Peru successfully secured a road construction project and needed high tensile geotextile for the job. They shared the index of the required non-woven polypropylene fabric with us, and upon checking, we found it to be consistent with our 500g polyester filament geotextile. We promptly provided the customer with the price and index information. After comparing it with their technical requirements, the customer’s personnel confirmed that our geotextile met their specifications.
To further validate the quality, the customer requested a sample, which we promptly sent on the same day. After a few days, the customer received the sample and conducted thorough testing, confirming that it met the required standards. Following subsequent communication and negotiation, the customer placed an order for three 40HQ geotextiles, indicating their satisfaction with our product.
This successful collaboration demonstrates our ability to meet specific project needs with our high-quality non-woven polypropylene fabric. We are committed to providing reliable solutions for road construction projects and look forward to delivering exceptional products and services to our customers.
3.1 Specification of Non Woven Polypropylene Fabric for Road Construction in Peru
Specification of Non-Woven Polypropylene Fabric for Road Construction in Peru:
- Total Non-woven Polyester Filament Geotextile: 60,000 square meters
- Weight: 500g
- Roll Size: 5.95 meters wide by 50 meters long
These specifications indicate that the non-woven polypropylene fabric for the road construction project in Peru requires a total area coverage of 60,000 square meters. The fabric has a weight of 500g per square meter, providing the desired strength and durability. Each roll of the fabric measures 5.95 meters in width and has a length of 50 meters, making it convenient for transportation and installation at the construction site.
These specifications reflect the necessary quantity, weight, and dimensions of the non-woven polypropylene fabric required for the road construction project, ensuring its suitability for the intended application.
4. Laying Method of Non Woven Geotextile Fabric
The laying method of non-woven geotextile fabric involves several techniques for proper installation. Here are the recommended methods:
4.1 Manual Roll and Pave
The fabric should be rolled out and laid manually. It is crucial to ensure a flat and even surface, allowing for appropriate deformation allowance.
4.2 Overlapping, Sewing, and Welding
For both long wire and short wire geotextiles, various methods can be employed. Overlapping, sewing, and welding are commonly used techniques. The stitching or welding width is typically more than 0.1m, and the lap width should be more than 0.2m. When geotextiles are expected to be exposed for an extended period, welding or stitching is necessary.
4.3 Stitching of Geotextile
All stitching must be continuous, and point stitching is not permitted. Before overlapping, there should be a minimum overlap of 150mm between geotextiles. The sewing needle should be at least 25mm away from the fabric’s edge (the exposed edge).
The most common method for sewn geotextile joints is the thread locking chain joint. The thread used for stitching should be made of resin material with a minimum tension of more than 60N. It should also possess chemical corrosion resistance and ultraviolet resistance equivalent to or exceeding that of the geotextile.
Any “missing stitches” on the sewn geotextile must be re-stitched at the affected area.
Appropriate measures must be taken to prevent soil, particulate matter, or foreign objects from entering the geotextile layer after installation.
The choice of natural lap, seam, or welding for cloth overlap should be based on the terrain and intended use of the geotextile.
By following these laying methods, non-woven geotextile fabric can be installed effectively to provide the desired functionality and performance in various applications.
