With low cost, simple construction, and convenient usage.

Product funtions

(1) Drainage Function:

PET Needle-punched non woven geotextile fabrics serve as porous permeable media that, when buried in the soil, gather water and facilitate its drainage from the soil. They can drain both vertically along their plane and horizontally, providing effective drainage for applications such as embankments, roadbeds, retaining walls, and consolidation of soft soil foundations.

(2) Filtration Function:

To prevent the infiltration of fine particles into the soil (piping phenomenon), traditionally, graded granular materials are used as a filtration layer. However, both woven and non-woven geotextile fabric can replace conventional granular materials, serving as effective filtration layers. In cases where high filtration requirements are not necessary, non-woven textiles are commonly chosen for use as filtration layers. 

(3) Isolation Function:

In geotechnical engineering, the phenomenon of mutual mixing between layers of different granular materials often occurs, leading to the loss of their intended properties. Placing geosynthetic materials between different granular layers can provide effective isolation. For instance, in the construction of gravel sub-layers on weak foundations, the interlayer placement of geotextiles effectively prevents the interpenetration of soil materials, controlling uneven settlement. The isolation function of geosynthetic materials has proven effective in highway construction and the treatment of soft soil roadbeds.

(4) Reinforcement Function:

PET Needle-punched non woven geotextile fabrics possess high tensile strength and large deformation ratios. When appropriately buried in the soil as reinforcement, they can control soil deformation and enhance soil stability.

(5) Protection Function:

PET Needle-punched non woven geotextile fabrics can diffuse concentrated stress and transfer stress from one object to another, preventing damage to the soil under external forces. They are primarily used in river channel regulation, embankment protection, bottom protection engineering, coastal moisture prevention, and road slope protection projects.

(6) Anti-seepage Function:

Coating the surface of geosynthetic materials with a layer of resin or rubber, or combining geosynthetic materials with plastic films to form impermeable materials known as geomembranes, achieves anti-seepage effects. Geomembranes are often composed of thin non-woven fabrics combined with thin films, and can be tailored to specific engineering needs, such as one fabric to one film, two fabrics to one film, or three fabrics to one film configurations. The chosen thickness of the non-woven fabric and film can be adjusted as needed, providing both waterproofing and anti-seepage effects simultaneously.

Application for roads

The application of PET filament needle-punched geotextile fabric in road construction is extensive:

1, Road Base Reinforcement:

PET filament needle-punched non woven geotextile fabric is utilized as a reinforcement material in road engineering to enhance the stability and deformation resistance of the road base. By embedding this geotextile in the roadbed soil, it effectively disperses and bears traffic loads, reduces road settlement, and prolongs the lifespan of the road.

2, Drainage System:

The geotextile's water permeability makes it an ideal choice in road drainage systems. It can be used as a drainage material beneath the waterproofing layer, facilitating the rapid removal of rainwater and preventing water from infiltrating into the lower layers of the roadbed, thereby preventing softening and damage.

3, Soil Erosion Control:

PET filament needle-punched non woven geotextile fabric can be employed to prevent soil erosion. Along road slopes, retaining walls, and other areas prone to erosion, it serves as an effective protective layer, preventing soil scouring from rainfall and water flow and preserving the integrity of road structures.

4, Filter Layer:

In road structures, PET filament needle-punched non woven geotextile fabric can function as a filter layer, preventing fine particles from entering the soil and avoiding piping phenomena, thereby enhancing the stability and durability of the road structure.

5, Soft Soil Treatment:

In the treatment of weak foundation soils, this geotextile is widely used to reinforce and stabilize soft soil foundations. By burying it in soft soils, it increases soil strength, reduces settlement, and provides a more reliable foundation for the road.

Overall, the multifunctional characteristics of PET filament needle-punched non woven geotextile fabric, including high strength, strong puncture resistance, acid and alkali resistance, make it a crucial geosynthetic material in road construction, contributing significantly to optimizing road structures and enhancing performance.
