Product Introduction
1、 Basic attributes
Material structure：8 oz Non Woven Geotextile is made of synthetic fibers (mainly polypropylene, etc.) through non-woven technology, without obvious weaving texture. The 8-ounce specification corresponds to a moderate weight per unit area, with a soft texture and a certain thickness.
Physical characteristics: uniform pore distribution, good breathability and permeability; Good flexibility, bendable and foldable, can adapt to different terrain contours, and is not easily damaged due to bending.
Chemical characteristics: It has tolerance to common acidic and alkaline substances, is not easily decomposed by microorganisms, and has a certain degree of UV resistance. It can maintain stable performance in outdoor environments.
2、 Core functions
Filtering function: By uniformly intercepting soil particles through pores, soil loss is prevented, while allowing water and gas to penetrate smoothly, avoiding pore blockage and maintaining normal exchange between soil and the outside world.
Reinforcement function: With moderate tensile and tear strength, embedded in structural layers such as roadbeds and slopes, it disperses the stress borne by the soil, enhances the overall stability of the structure, and reduces the risk of settlement and collapse.
Isolation function: It can separate materials such as sand, gravel, and soil with different particle sizes, avoiding material mixing and performance degradation, and ensuring the integrity and stability of the engineering structural layer.
3、 Main features
Strong adaptability: The 8-ounce specification balances lightness and strength, making it easy to cut and lay, as well as meeting the basic needs of filtration and reinforcement in conventional engineering. It is widely applicable in various scenarios.
Convenient construction: lightweight and flexible, easy to fit the terrain during laying, not prone to wrinkling or hollowing, can greatly reduce construction difficulty, improve construction efficiency, and reduce labor costs.
High cost-effectiveness: moderate specifications, mature production technology, and relatively controllable costs; At the same time, it has certain durability, can match the service life of conventional engineering, and has outstanding long-term economic efficiency.

Product Application
1、 Road and Municipal Engineering
Roadbed filtration isolation: It is laid between the roadbed soil and the sand and gravel cushion layer, intercepting soil particles to prevent mixing, while diverting moisture to avoid water accumulation and softening of the roadbed. It is suitable for the construction of conventional roads such as rural roads and municipal branches, and meets the basic bearing requirements.
Road maintenance assistance: When renovating old road surfaces, it is laid between the new and old surface layers to isolate impurities and reduce disease transmission, protect the structure of the new surface layer, and extend the service life of small and medium-sized roads.
Pedestrian walkway and square foundation: used for the foundation treatment of pedestrian walkways and community squares, separating soil from paving base materials, enhancing foundation stability, and preventing pavement settlement and cracking.
2、 Water Conservancy and Agricultural Engineering
Small irrigation canal protection: Installed on the slopes and bottoms of farmland irrigation canals and drainage ditches, it isolates soil and water bodies, reduces channel erosion and sediment deposition, improves irrigation efficiency, and is suitable for small-scale rural water conservancy facilities.
Greenhouse foundation treatment: It is laid between the soil layer and gravel layer of the greenhouse foundation to prevent seepage and drainage, regulate the soil moisture inside the greenhouse, and avoid the influence of foundation moisture on the structure of the greenhouse.
Artificial water features and small ponds: used for the bottom or slope of artificial water features in courtyards and small ponds in rural areas, to isolate soil and impermeable membranes, prevent soil particles from blocking the impermeable layer, and ensure clear water bodies.
3、 Architecture and Ecological Restoration
Low rise building foundation: In the foundation of low rise residential buildings and factories, different soil layers are separated, impurities are filtered, uneven settlement of the foundation is reduced, and it is suitable for small building projects in soft soil areas.
Slope ecological protection: used for small-scale restoration of park slopes and rural mountains, fixing soil to prevent loss, and providing a foundation for vegetation growth, helping with "engineering protection+simple greening".
Small parking lots and storage yards: Lay the ground base layer of small parking lots and temporary cargo storage yards to enhance the ground bearing capacity, prevent ground collapse, and reduce infrastructure construction costs.
8-ounce non-woven geotextile, with moderate strength, good filtration and isolation performance, and high adaptability, focuses on small and medium-sized engineering scenarios, covering multiple fields such as road and municipal engineering, water conservancy and agriculture, and building ecological restoration. Whether it is to ensure the stability of the foundation of conventional roads and low rise buildings, to assist in the realization of small-scale water conservancy and courtyard water features in rural areas, or to support small-scale slope protection and temporary site construction, it can solve basic problems such as soil mixing, water accumulation, and structural settlement in engineering with the advantages of "practicality and economy", without having to bear the additional cost of high-grade geotextiles, becoming an ideal material for balancing performance and cost-effectiveness in small and medium-sized engineering construction.
