Product Introduction
Basic attributes
Geotextile Fabric 12 is made from high-strength synthetic fibers such as polypropylene and polyester as the core raw materials, processed through professional weaving techniques. Its weight per square yard reaches the standard specification of 12 ounces, which belongs to the category of medium weight geotextiles. It not only ensures structural strength but also avoids construction inconvenience caused by excessive weight. The fabric material is flexible and elastic, presenting a uniformly distributed porous morphology on the microstructure. The porosity is moderate, allowing water infiltration and effectively intercepting soil particles. At the same time, it has excellent physical stability and can maintain stable morphology and performance under different environmental conditions such as high and low temperatures, humidity, etc., meeting the application needs of various engineering projects.
Core functions
Structural support: Relying on the high-strength tensile and tear resistance provided by high-quality fiber materials, a stable mechanical support structure is formed inside the soil. When the soil is subjected to load pressure or external impact, the fabric can evenly distribute stress to a larger range, effectively resist base settlement, deformation, and even collapse, provide continuous and stable support and guarantee for engineering structures such as roads, dams, and building foundations, and reduce the risk of structural instability.
Soil and water regulation: Utilizing its uniform porous structure to achieve synergistic effects of filtration and drainage. During the process of soil infiltration, fabrics can accurately intercept small particles in the soil, preventing them from flowing away with water and causing structural damage to the soil, thus playing a role in soil conservation and stabilization; At the same time, pore channels can quickly guide the discharge of permeable water, avoiding the accumulation of water in the base layer to form accumulated water, reducing the softening, erosion, and frost heave hazards of accumulated water on the soil, and maintaining soil water balance.
Isolation and protection: By utilizing a tight and regular arrangement of fibers, a physical barrier is formed between materials of different properties, effectively blocking the mixed infiltration of materials with different particle sizes such as sand, soil, and concrete, ensuring the purity and functional independence of each structural layer. In addition, the fabric itself has certain anti-seepage properties, which can reduce the infiltration of water into the foundation layer, reduce the erosion and damage of water to the foundation structure, and extend the service life of the engineering foundation.
Main features
Convenient and efficient construction: Due to its flexible texture and moderate weight specifications, it is easy to cut, transport, lay, and splice during the construction process. It can be flexibly adjusted according to the terrain, topography, and size requirements of the project site, and can be laid smoothly on flat, sloping, or complex terrains. When splicing, it can be quickly fixed by overlapping, sewing or hot melting, greatly shortening the construction period and improving the efficiency of the project construction.
Durable and long-lasting: After special processing, the fabric has excellent resistance to UV aging and is not easily brittle or broken even when exposed to sunlight for a long time; At the same time, it has excellent resistance to acid and alkali, as well as chemical corrosion, and can adapt to soil acidic and alkaline environments and industrial wastewater erosion; It can also resist biological erosion such as microorganisms and insect infestations, and maintain stable performance for a long time in various harsh environments such as outdoor, underground, and underwater, effectively extending the service life of the project and reducing maintenance costs in the later stage.

Product Application
Road engineering field
12 ounce geotextile plays a crucial role in the construction of road base and subgrade layers. It can be laid between the roadbed soil and the sand and gravel base, using its isolation function to prevent the mixing of materials of different particle sizes, avoiding the roadbed soil from being squeezed and penetrated by sand and gravel, and preventing sand and gravel particles from entering the roadbed soil and causing a decrease in structural strength. Its high-strength tensile performance can effectively disperse the stress generated by vehicle loads, reduce roadbed settlement and deformation, and delay the occurrence of road cracking, collapse and other diseases. In addition, the drainage function of the fabric can timely drain the accumulated water in the roadbed, reduce the softening erosion of moisture on the roadbed, and extend the service life of the road, especially suitable for scenarios such as soft soil roadbeds and roads in rainy areas.
