Polypropylene geotextile fabric, also known as polypropylene geotextile, is often made from polypropylene or fibers processed by woven, needle-punched or heat-bonded methods. Polypropylene geotextile fabric is the kind of non woven geotextile fabric which is robust, durable, permeable and resist to deformation. BPM short fiber nonwoven polypropylene geotextile fabric is widely used to increase ground support and soil stabilization in a given location, it has the characteristics of high tensile strength, high elongation rate, excellent UV stabilization, excellent filtration and good abrasion resistance, etc. It is widely used for filtration, separation, protection, drainage applications in civil environmental engineering and construction projects. Polypropylene geotextile has the following adavantages.
- Polypropylene geotextile has good air permeability and water permeability, allowing water to pass through, thereby effectively intercepting sand and soil loss.
- The polypropylene geotextile fabric can effectively diffuse, transfer or decompose concentrated stress to prevent soil from being damaged by external forces.
- The polypropylene geotextile fabric can be used to prevent mixing between the upper and lower layers of sand, gravel, soil and concrete.
- The mesh is not easy to be blocked, and the mesh structure formed by the unshaped fibrous tissue has strain and mobility.
- High water permeability, it can still maintain good water permeability under the pressure of soil and water.
- Corrosion resistance, using polypropylene or polyester and other chemical fibers as raw materials, acid and alkali resistance, no corrosion, no insects, and anti-oxidation.
- Simple construction, light weight and easy to use.
Under normal circumstances, polypropylene is only more resistant to sunlight than polypropylene. Polypropylene has to be treated with ultraviolet rays to meet the requirements of long-term exposure. However, geotextiles are generally not exposed to the sun or air, and the material is not required to have too high resistance. More importantly, polypropylene fiber has strong acid and alkali resistance, and can guarantee 100% stable performance in various geological conditions and use environments. The acid resistance of polyester is fair, but the alkali resistance is very poor, and weak alkali can decompose it, so it is not suitable for use in any alkaline environment. The leachate in the landfill contains complex heavy metal decomposition products, including strong acids and alkalis. Nowadays, Polypropylene geotextile fabric is generally used in foreign landfill projects. Polypropylene geotextile construction method for waste landfill project.
- Storage, transportation and treatment of geotextile.Polypropylene geotextile rolls should be protected from damage before installation and laying. Polypropylene geotextile fabric rolls should be stacked in a place where no water will accumulate after treatment, and the stack height should not exceed the height of four rolls. During transportation on site, the geotextile rolls must be protected to avoid any damage (including transporting the rolls from the storage place on the site to the working surface).
- The connection and stitching of geotextile. Hot melt welding is the common method used on almost horizontal surfaces (10% slope or less than 10%). On slopes greater than 10%, continuous stitching or hot melt welding of geotextiles. The bonding wire must use a polymer material with a tensile strength exceeding 60N. The chemical resistance and UV resistance of the bonding wire must be equal to or better than the polypropylene geotextile. The number of people in urban areas in Lao PDR is beginning to grow more rapidly and the amount of waste is increasing.
With the increasing number of domestic wastes, the Lao government vigorously develops landfill projects, and the government allocates funds to support these landfill projects to ensure the country’s environmental sanitation and people’s water safety issues.
In 2020, Lao customers got a bidding landfill project form their government. He needed three kinds of geosynthetic products including geomembrane, geotextile and composite drainage net, etc. We sent geotextile, geomembrane, composite drainage net samples to customers for testing. Each sample was 2 square meters in size. Our products have been tested by professional IGS in Thailand. A customer from Laos placed an order for us.
