Products Introduction：
Heavy Gauge Woven Geotextile is a type of thick and heavy-duty functional geosynthetic material made from high-strength polyester (PET) or polypropylene (PP) filaments through precision weaving processes. Its core positioning is "structural stability barrier under heavy loads and harsh environments". Its weight is usually between 300-1000g/m ². With high-density woven structure and high modulus fiber characteristics, it focuses on the three core functions of "high-strength reinforcement, precise isolation, and wear resistance". It is mainly used in civil engineering scenarios that can withstand heavy loads and resist complex environmental erosion, such as heavy-duty roads, mining yards, dam reinforcement, etc.
Product Features：
1. Ultra high mechanical strength, suitable for heavy-duty reinforcement
Using high modulus filament raw materials and dense weaving technology, the longitudinal and transverse fracture strength can reach 50-150kN/m, and the tear resistance strength is ≥ 5kN, far exceeding ordinary geotextiles (conventional woven geotextiles have a strength of ≤ 30kN/m); Excellent creep resistance, with a deformation rate of ≤ 2% under long-term constant heavy loads (such as mining trucks and container yards), can effectively disperse local stress, prevent settlement and collapse caused by soil and road gene load concentration, and adapt to high-strength stress scenarios such as heavy-duty roads and port yards.
2. Wear resistant and impact resistant, able to withstand harsh construction and use
The surface of the fabric presents a tight and thick woven texture, with a wear resistance of up to 1000 Martindale abrasion tests without obvious damage. It can resist severe external impacts such as heavy roller compaction, gravel laying friction, and engineering equipment dragging; The edges are treated with special locking to avoid fiber detachment caused by pulling during construction. Even in rough construction environments such as mines and infrastructure, the structural integrity can be maintained, reducing rework caused by material damage.
3. Precise isolation to ensure independent and stable structural layers
By precisely controlling the machine aperture (0.1-0.5mm), the interception rate of soil fine particles, sand and gravel micro materials is ≥ 99%, which can strictly separate soil materials, sand and gravel or subgrade layers of different grades, prevent interlayer particle migration and mixing - for example, in heavy-duty roadbeds, it can isolate the roadbed soil from the graded gravel layer, avoid fine soil blocking the gravel holes and causing drainage failure, and prevent gravel from embedding in soft soil and reducing bearing performance, ensuring the independent and stable function of each structural layer.
4. Weather resistant and corrosion-resistant, suitable for complex and extreme environments
The raw materials have undergone triple stabilization treatment with UV resistance, acid and alkali resistance, and microbial resistance, and can work stably in the extreme temperature range of -40 ℃ to 90 ℃. They are resistant to saline alkali soil, seawater immersion, industrial wastewater erosion, and outdoor strong sunlight aging; In complex environments such as coastal ports, saline alkali mines, and chemical industrial parks, the service life can reach 15-25 years, far exceeding that of ordinary geotextiles (5-10 years), significantly reducing maintenance and replacement costs in the later stage.
5. Stable structure, compatible with multiple construction processes
The fabric has a tight structure and good dimensional stability, with a thermal shrinkage rate of ≤ 1% (2 hours at 100 ℃), and is not easily wrinkled or shrunk due to temperature changes after laying; Compatible with subsequent construction processes such as asphalt paving, concrete pouring, and crushed stone compaction - the high temperature resistance (≤ 180 ℃) ensures that the asphalt does not melt or deform during paving, the high-strength characteristics withstand concrete vibration impact, and are suitable for composite engineering requirements such as "reinforcement+paving" and "reinforcement+protection".

Product Applications：
Heavy-duty highway construction on soft soil terrain faces prominent engineering challenges, including uneven foundation settlement, pavement rutting, and soil layer mixing under long-term heavy vehicle loads. As a high-strength geosynthetic material, Heavy Gauge Woven Geotextile has become a core functional material for soft foundation stabilization of heavy-load highways, relying on its ultra-high tensile strength, excellent load dispersion performance and stable structural durability. Compared with conventional geotextile products, it solves the structural instability problems of soft soil roadbeds under dynamic cyclic loads, ensuring long-term and stable operation of highway infrastructure.
In the overall road foundation design, different geotextile types are selected according to differentiated functional requirements, forming a complementary application system. Woven Type Geotextile represented by heavy gauge woven products focuses on structural reinforcement and isolation, which is irreplaceable for bearing heavy pressure and limiting soil displacement. In contrast, Non Woven Polypropylene Geotextile Fabric is mainly used for auxiliary filtration and drainage of roadbeds. Its random fiber structure realizes rapid water seepage, prevents rainwater accumulation from softening the foundation, and cooperates with woven geotextiles to optimize the internal water balance of the roadbed. For slope auxiliary protection of highway road sections, Non Woven Coir Geotextiles are often matched for ecological protection, which assists in soil fixation and vegetation growth while stabilizing shallow slope soil.
The core application value of Heavy Gauge Woven Geotextile in heavy-duty highway soft foundation lies in three key functions: isolation, reinforcement and settlement control. During construction, the material is laid between the soft soil base and the gravel cushion layer. Its tight woven structure completely isolates the fine-grained soft soil and coarse gravel filler, avoiding the mixing of soil and stone that leads to reduced foundation bearing capacity. Its longitudinal and transverse high tensile strength can effectively disperse concentrated vehicle loads, reduce the vertical pressure on the soft soil layer, and greatly inhibit uneven settlement of the roadbed.
In addition, the material retains reasonable pore uniformity while ensuring high strength. It cooperates with the drainage advantage of Non Woven Polypropylene Geotextile Fabric to discharge interstitial water in the soft soil layer in time, accelerate soil consolidation, and improve the overall compactness and bearing capacity of the foundation. Different from the ecological orientation of Non Woven Coir Geotextiles, heavy gauge woven geotextile focuses on structural engineering performance, adapting to long-term heavy traffic, seasonal temperature changes and complex soil environment erosion.
In practical engineering cases, the combined application of multiple geotextiles effectively extends the service life of heavy-duty highways, reduces later maintenance frequency, and solves common problems such as pavement cracking and subsidence of soft foundation roads. With reliable physical properties and targeted functional design, Heavy Gauge Woven Geotextile has become an essential material for high-standard heavy-load highway foundation reconstruction and new construction.
The Heavy Gauge Woven Geotextile, with its core advantages of "ultra-high strength resistance to heavy loads, wear resistance, wear resistance, precise isolation and stable structure, weather resistance, corrosion resistance, and long service life", accurately solves the core pain points of "insufficient structural bearing capacity, easy material damage, and high maintenance costs" in heavy-duty engineering and complex environments. It is a "rigid protection flexible solution" for modern heavy-duty civil engineering.
Compared to traditional heavy-duty reinforcement materials such as concrete cushion layers and thin steel plates, this product not only reduces material costs by 30% -50%, but also improves construction efficiency by 2-3 times due to its flexible and easy to lay characteristics, avoiding the limitations of rigid materials such as "difficult to fit and easy to crack". Its wide application not only promotes the development of heavy-duty engineering towards "lightweight, green, and low-cost" direction, but also provides solid guarantees for the safety and stability of key infrastructure such as mines, ports, and water conservancy through reliable long-term performance. It is the preferred category of geotechnical materials for heavy-duty and harsh environments.
