Non Woven Geotextile Fabric for Pavers
1. Precise filtration, guarding the base layer: The pores are uniform and controllable, effectively filtering sediment, blocking the upwelling of fine soil, preventing blockage of the paving base layer, ensuring smooth drainage, and extending the service life of the paved road surface.
2. Flexible reinforcement and stable structure: Non woven fibers interweave to form flexible supports, dispersing vehicle and pedestrian loads, reducing settlement and cracking of the paving base, and making the brick laying more stable.
3. Convenient construction, cost reduction and efficiency improvement: easy to cut quality, no need for complex tools to lay, suitable for irregular paving areas; Shorten construction time and reduce labor and project costs.
4. Environmentally friendly and durable, eco-friendly: degradable or weather resistant polymer materials are used to prevent long-term corrosion and aging and reduce replacement in the later period; Some products are compatible with vegetation growth, helping to pave the way for ecological development.
Products Introduction：
Non Woven Geotextile Fabric for Pavers is a high-performance non-woven geosynthetic material designed specifically for brick laying projects such as masonry and concrete. It uses short fibers of polypropylene (PP) or polyester (PET) as raw materials, and randomly interweaves and solidifies the fibers through processes such as needle punching and hot melt, forming a flexible sheet material with a uniform pore structure. In the brick laying system, this material is laid between the base soil and the bricks, mainly responsible for filtering, isolation, reinforcement, and protection functions. It can effectively solve the common problems of base settlement, weed growth, and poor drainage in traditional brick laying projects, providing stable and durable foundation guarantees for brick laying areas such as courtyards, sidewalks, and parking lots. It is a key material to improve the quality and service life of brick laying projects.
Product Features：
1. Precise filtration and anti blocking design: The three-dimensional pore structure formed by random interweaving of fibers has uniform and reasonably distributed pore sizes (usually between 0.05-0.5mm), which can allow rainwater and surface water to penetrate smoothly, while efficiently blocking the upwelling of fine particles (such as clay and silt) in the base soil, avoiding blockage of brick joints or sand and gravel cushion layers, maintaining smooth drainage in the brick laying area for a long time, and reducing the problem of base softening caused by accumulated water.
2. Flexible reinforcement and load dispersion: Although the texture is soft, the interwoven fiber network has excellent tensile strength (generally 10-30kN/m) and tear resistance. In the laying of brick base, it can disperse the local loads brought by pedestrians and vehicles like an "invisible skeleton", evenly transmit stress to a larger range of soil, effectively suppress the settlement and deformation of the base, prevent loosening, indentation, fracture and other phenomena of brick laying, and enhance the overall structural stability.
3. Convenient construction and scene adaptation: The texture is light and thin (usually 100-500g/m ² per unit area), with excellent flexibility. It can be cut and spliced freely according to the shape of the brick laying area (such as irregular courtyards, bends, slopes), without the need for professional equipment. When laying, it can closely adhere to the surface of the base layer without wrinkles or hollows, and is suitable for various types of base layers such as sand, gravel, and concrete, greatly shortening the construction period and reducing labor costs.
4. Durable, damage resistant and compatible with the environment: weather resistant raw materials, UV resistant and anti-aging treatment can resist natural erosion such as outdoor direct sunlight, rain soaking, temperature change, and the service life can reach 5-15 years. At the same time, the material has stable chemical properties, acid and alkali resistance, corrosion resistance, and will not cause pollution to the soil or surrounding environment. Some biodegradable models can also naturally decompose after the service life expires, balancing functionality and ecological friendliness.

Product Applications：
1. Paving in courtyards and landscapes: In the stone paving of family courtyards and terraces, it is laid between the sand and stone cushion layer and the brick paving to block the mixing of soil fine particles with the cushion layer, prevent weeds from drilling out from the brick joints, and maintain the cleanliness and beauty of the courtyard; At the same time, accelerate rainwater infiltration to avoid water accumulation after rain affecting the use of the courtyard.
2. Pedestrian walkways and pedestrian streets: In the laying of floor tiles for urban sidewalks and commercial pedestrian streets, they are used as base reinforcement materials to disperse pedestrian foot loads and reduce tile loosening and fragmentation; When used in conjunction with permeable bricks, it can improve overall drainage efficiency, solve road surface water problems during rainy seasons, and ensure pedestrian safety.
3. Parking lots and private lanes: In the brick laying project of parking lots and private lanes that can withstand vehicle crushing, their reinforcement performance is used to enhance the deformation resistance of the base layer, preventing the floor tiles from sinking or breaking due to heavy pressure; The efficient drainage function can quickly drain rainwater, avoiding water accumulation that corrodes vehicles or damages the underlying structure.
4. Swimming Pool and Outdoor Leisure Area: When laying bricks in areas such as the non slip tiles around the swimming pool, outdoor barbecue area, garden trail, etc., laying this geotextile can isolate the soil from the brick layer, prevent soil erosion in humid environments from causing brick collapse, and inhibit the growth of moss and weeds, reducing daily maintenance workload.
Non Woven Geotextile Fabric for Pavers has become an ideal auxiliary material for various brick laying projects due to its core advantages of precise filtering and anti blocking, flexible reinforcement, convenient construction, and durability and environmental protection. It solves the pain points of loose bricks, water accumulation, weeds, etc. from the grassroots source, and significantly improves the structural stability and service life of the brick laying area by optimizing drainage, dispersing loads, and isolating impurities. Whether it is the renovation of small family courtyards or the construction of large municipal sidewalks, their characteristics of "low cost, high efficiency, and long service life" can bring tangible benefits to the project. They are brick laying materials that balance functionality and economy, providing reliable guarantees for creating clean, durable, and low maintenance brick flooring.
