PP geotextile is an important high-performance geosynthetic material, which plays an important role in the construction of water conservancy, hazardous waste landfill, tailings reservoir, airport, high-speed rail and other projects.
Case Analysis
- Location – Jordan
- Product – 500g PP Geotextile Mat
- Project – Landfill
Issue
In October 2021, BPM received an email inquiry from a project contracting company in Jordan. According to the content of the email and the attached project information, after analyzing the technical parameters of the product, BPM’s technical department concluded that the project needs to use 500g/m2 polypropylene (PP) non-woven geotextile.
According to the project information, the project is a waste disposal project, which is used to deal with the daily domestic waste generated by nearby cities. The use of polypropylene (PP) non-woven geotextiles in the project is to play an isolation and filtration role in the landfill.
It is mainly used to prevent some solid waste debris from entering the soil, and at the same time, it will also filter and discharge the waste liquid generated in the waste.
Solution
To do a good job in the construction quality control of non-woven PP geotextile mat, it is necessary to grasp the two aspects of raw material quality control and construction process control. The quality control of materials is to ensure that the supplier of the product has the certificate of conformity, the properties of the material and the specification. In the control of the construction process, we must first ensure that the materials used in the construction process are consistent with the design and can play a role. For: elongation at break greater than 30%, tensile strength at break greater than or equal to 7.5k N/m, burst strength CBR greater than 1.5k N, tear strength greater than 250N, permeability coefficient less than 1×10cm/s, and then quality inspection The center inspects each index until it passes the inspection. Secondly, in the construction process, the construction should be carried out according to the laying measures designed by the engineer, and the follow, follow, and pressure should be implemented. And you need to check the joints, check the joints for wrinkles or burns. Once a problem occurs, it should be fixed in time. During the earthwork backfill work, the appearance should be checked at any time, and the flatness, leakage, cracks, etc. of the geotextile should be checked.

The application of geotextile can enhance the stability of the roadbed and the safety and stability of the road. According to BPM’s experience in roadbed reinforcement construction,
In addition to meeting the infiltration requirements, the geotextile should also be covered with a thin layer of sand, generally 8-9cm thick, in order to obtain satisfactory results. If used in road foundation reinforcement projects in cold regions, a new type of permeable layer can be formed, which can cut off the capillary, so that the water in the lower soil cannot be supplied to the unsaturated soil layer above it.
Advantage
1) High tensile strength, under the same gram weight, the longitudinal and transverse tensile forces are higher than other needle punched non-woven fabrics.
2) Good elongation, the geotextile has good elongation under a certain stress, so that the geotextile can adapt to the uneven base.
3) Good drainage performance and vertical permeability. Due to the large thickness of the non-woven geotextile and the needling reinforcement, it has good plane drainage performance and vertical permeability.
4) Good anti-ultraviolet performance, non-woven PET geotextile has good anti-ultraviolet radiation performance, ensuring long service life.
5) Good corrosion resistance: Non-woven geotextiles are resistant to different chemical substances such as acid and alkali, gasoline, diesel in the soil.
6) Good anti-friction performance, the friction coefficient of the geotextile is higher than that of another conventional geotextile, and it is not easy to fluff and damage.
7) Good creep resistance. Nonwoven geotextiles have good creep resistance and long-lasting functionality.
The application of PP geotextile mat in other projects
In addition, geotextiles can also prevent many roadbed hazards such as frost. This is a foundation soil under the repeated action of dynamic loads. The soil pore water pressure increases to the extent that the strength of the soil cannot be suppressed, and the soft soil is squeezed into the lower coarse-grained soil layer. The action of seepage force caused by hydraulic slope is called coarse-grained soil. When the soil is seriously polluted, it can be boiled in a coarse-grained layer.
The role of geotextiles in the ecological environment: how do geotextiles maintain the ecological environment? Geotextiles are suitable for greening on planes, slopes and high slopes, allowing moisture to flow between the bag and the soil in the bag, which is the moisture needed for vegetation loss, and will never cause fruit or soil erosion or watering due to rain. water. In addition, geotextiles are ideal seeding blocks for plants. It is permeable and impermeable to soil. Grass can grow from the outside and grow in the name. , Regarding friendly vegetation, the root system of the vegetation can grow between the bags and the bags, and the root system connects each non-woven geotextile into a whole, building a stable and permanent ecological slope.
The second role of geotextiles in the ecological environment: greening the ecological environment has always been the voice of society. Geotextiles have attracted public attention in this project. At the same time, the ecological slope protection engineering system uses raw materials to construct flexible slopes and retaining walls. , and complete the plane greening of the reservoir and slope bank, expressing the establishment of a conservation, energy saving, lively and breathable ecological project in the southern district. The project does not require hard materials such as steel, lime, and stone with high energy consumption and high pollution.
The third effect of geotextiles on the ecological environment: geotextiles, as a multi-functional product, can reduce or even avoid secondary pollution. Non-woven geotextiles have good water permeability and breathability. It can be buried in fill waste. Improve the acceptance conditions for filling waste, enhance the tensile strength and deformation resistance of the filling, and improve the stability of the project structure. Non-woven geotextiles under the correct conditions of use. The anti-seepage layer adopts needle-punched non-woven geotextile and HDPE geomembrane as engineering materials. The anti-seepage layer is designed to slow the infiltration of polluted wastewater and the migration of pollutants, while guiding the drainage layer to discharge wastewater.
