Paver Geotextile Fabric
1. Stabilize the base layer and prevent settlement: Enhance the overall integrity of the soil below the pavement, suppress particle movement, avoid sinking and loosening due to vehicle compaction, and ensure long-term stability of the pavement structure.
2. Barrier filtration and anti clogging: Accurately isolate sand, gravel, and soil to prevent fine soil particles from seeping into the gaps of the pavement and causing clogging, while allowing moisture to penetrate and maintain the dryness of the base layer.
3. Wear resistance and aging resistance: Resistant to friction and outdoor environmental erosion during pavement installation, not easily damaged or degraded, extending the service life of the pavement system.
4. Strong adaptability and easy construction: It can be cut according to the paving area, fits the curvature of the ground, and is convenient for manual paving, improving construction efficiency.
Products Introduction：
Paver Geotextile Fabric is a specialized geosynthetic material designed specifically for laying masonry, concrete, and other paving materials. It is made from high-strength polyester or polypropylene fibers through needle punching or weaving processes, with a tight fiber structure and stable physical properties. As the core auxiliary material of paving engineering, its core function is to strengthen the stability of the base layer, block the mutual infiltration between soil and paving layer, optimize the drainage system, thereby avoiding problems such as loosening, settlement, and backflow of the paving surface. It provides lasting structural guarantee for paving scenes such as courtyards, sidewalks, and parking lots, and is a key material to improve the quality and service life of paving engineering.
Product Features：
1. Directional reinforcement and deformation resistance: Using a special fiber arrangement process, a structure with directional tensile strength is formed, which can effectively resist the lateral thrust and vertical pressure generated by paving materials and external loads (such as pedestrians and vehicles). Even in the presence of slight settlement at the soil base, it can suppress the displacement of paving units through its own toughness, prevent gaps, protrusions, or collapses, and maintain the smoothness of the paving surface.
2. Precise blocking and filtering performance: The fiber pore size is precisely designed to strictly block the infiltration of fine particles (such as clay and silt) from the base soil into the gaps of the pavement layer, avoiding pavement hardening or drainage blockage caused by soil accumulation. It also allows rainwater and surface water to quickly penetrate below the base layer through the pores, preventing water from accumulating at the bottom of the pavement layer and reducing problems such as frost heave and moisture regain.
3. Wear resistance, abrasion resistance, and environmental tolerance: The surface has been hardened to withstand the friction, rolling, and tool scraping of bricks and stones during paving construction, and is not easily damaged; At the same time, it has excellent resistance to UV aging and acid alkali corrosion. When exposed to sunlight, rain, and humid environments outdoors for a long time, its physical properties decay slowly, and its service life can reach more than 10 years.
4. Suitable matching and easy construction: The texture is flexible and has good extensibility, which can closely fit different base terrains (such as flat, gentle slopes, and curved areas), without obvious wrinkles or hollows; Lightweight and easy to cut, the size can be quickly adjusted according to the shape of the paving area (such as irregular courtyards, irregular sidewalks), and manual paving does not require professional equipment, greatly reducing construction difficulty and time costs.

Product Applications：
1. Courtyard and Landscape Paving: In the courtyard stone pavement and terrace brick and stone paving, it is laid between the sand and gravel cushion layer and the paving material to block the mixing of soil and sand and gravel, prevent unevenness on the paving surface due to loose base layer, and accelerate rainwater drainage to keep the courtyard dry.
2. Construction of sidewalks and pedestrian streets: used for laying the base layer of floor tiles for urban sidewalks and commercial pedestrian streets, enhancing the road's resistance to trampling, reducing the loosening and breakage of floor tiles caused by long-term pedestrian traffic, and extending the maintenance period of sidewalks.
3. Parking lot and driveway paving: In parking lots or private lanes paved with permeable bricks or interlocking bricks, as a base reinforcement material, it disperses the pressure of vehicle loads on the soil, prevents the tiles from cracking due to heavy pressure, and ensures that rainwater can quickly drain through the brick joints to avoid water accumulation.
4. Paving around the swimming pool and water features: In the installation of anti slip bricks on the edges of the swimming pool and water feature trails, they play a role in blocking the soil and paving layer, preventing soil erosion in humid environments that may cause pavement collapse, and reducing the erosion of moisture on the base layer.
5. Municipal and public area paving: Suitable for stone slab paving in parks and squares, permeable brick paving in campus walkways, and other scenarios. By strengthening the stability of the base layer, reducing the frequency of paving maintenance in densely populated areas, and improving the safety and aesthetics of public spaces.
Paver Geotextile Fabric, as a specialized geotechnical material for paving engineering, plays a key role in various paving scenarios such as courtyard landscapes, sidewalks, parking lots, etc. due to its core advantages of directional reinforcement, deformation resistance, precise barrier filtration, wear resistance, weather resistance, and strong adaptability. It fundamentally solves the problem of pavement damage caused by unstable base, soil infiltration, and poor drainage in traditional paving engineering. It can not only extend the service life of the paving structure, but also reduce the labor and economic costs brought by later maintenance. Whether it is the renovation of small family courtyards or the construction of large municipal public areas, this product can provide reliable structural support for paving projects, making it an ideal choice for creating durable, beautiful, and low maintenance paving surfaces.
