Explore our industrial-grade geotextiles, geomembranes, and geocells engineered for extreme durability and environmental compliance.
The global construction and environmental engineering sectors are undergoing a massive transition towards sustainable, highly resilient infrastructure. Within this macro-environmental trend, the demand for 140g m² non-woven geotextiles has experienced exponential growth. As a highly versatile material grade (equivalent to roughly 4.1 ounces per square yard), the 140g/m² specification offers the optimal balance between mechanical tensile strength, hydraulic conductivity, and cost-efficiency.
Historically, heavy civil infrastructure projects relied on thick gravel layers for soil filtration and separation. However, modern geotechnical analysis proves that incorporating a needle-punched non-woven geotextile drastically improves project longevity while reducing carbon footprint and aggregate consumption. Globally, industrial projects—ranging from high-speed railway networks in Europe and the Belt and Road initiative transit routes in Central Asia, to massive waste management containment yards in North America—mandate the inclusion of certified geosynthetic separators to prevent subgrade contamination and ensure sustainable drainage pathways.
Leveraging 140g m² non-woven fabrics to address environmental containment, hydraulic control, and structural load distribution challenges.
Placed along river banks, canals, and agricultural drainage canals, the 140g/m² geotextile filters out fine particles while permitting high-rate water passage. This prevents internal soil erosion (piping) and maintains structural stability under high hydraulic pressure.
Acts as an indispensable protective layer. Positioned between sharp aggregate bases and HDPE geomembrane liners, it absorbs localized stresses and prevents geomembrane puncture from sharp gravel, extending containment cell lifetimes.
By preventing the migration of fine subgrade silt into the coarse aggregate base layer, the geotextile preserves the structural integrity and load-bearing capacity of highways, runways, and access pathways, preventing rutting and cracking.

A look into our manufacturing pipeline ensuring strict mechanical and hydraulic performance standards.
The main raw materials of geotextile are polyester chips (PET), polypropylene filament (PP), and viscose fiber. These raw materials undergo rigorous quality control inspections, chemical characterization, and systematic storage to ensure their purity, stability, and UV resilience from the outset.
After the raw polyester chips are melted at high temperatures, they are extruded into a molten state by a screw extruder. Polypropylene filament and viscose fibers are mixed in precise ratios. Temperature, hydraulic pressure, and throughput speed are monitored digitally to maintain homogeneous polymer distribution.
The molten mixture is extruded through ultra-fine spinnerets to form individual continuous micro-fibers, which are immediately deposited onto a continuous moving conveyor belt to form a uniform, multi-layered web structure. Orientation, depth, and density are controlled via localized air currents.
The loose fiber web is routed through heavy-duty industrial needle punching looms. Thousands of barbed needles strike the web, interlocking the fibers mechanically to provide high structural stability. The web is draft-cured under precise thermal conditions to stabilize physical characteristics.
The finished non-woven geotextile is trimmed to standard or custom widths (ranging from 1m to 6m) and wound onto heavy-duty cardboard cores. Every roll is measured for length, thickness, and total weight, ensuring exact alignment with customer purchase specifications.
Samples from every production batch undergo comprehensive laboratory testing. Properties analyzed include mass per unit area (140g/m² +/- 5%), tensile strength (MD and CMD), hydraulic permeability, and CBR static puncture resistance before final warehouse staging.

While 140g m² non-woven geotextiles represent a core product line, their application is frequently coupled with geomembranes to form composite anti-seepage structures. The geomembrane acts as an absolute hydraulic barrier, while the non-woven geotextile serves as a mechanical cushion, shielding the membrane from mechanical damage and relieving local pore water pressures.
Proper field execution is vital to achieving the intended service life of these systems:
Understanding chemical properties, mechanical strengths, and environmental longevity to select the correct geotextile formulation.
| Technical Characteristic | PET (Polyester) 140g M² | PP (Polypropylene) 140g M² | Application Selection Rule |
|---|---|---|---|
| Tensile Strength (MD) | ≥ 9.5 kN/m | ≥ 11.5 kN/m | PP is preferred for high-stress road subgrades. |
| Elongation at Break | 50% - 80% | 45% - 70% | PET exhibits higher flexibility in uneven foundations. |
| CBR Puncture Resistance | ≥ 1.5 kN | ≥ 1.8 kN | PP offers superior resistance to sharp aggregate drop damage. |
| Acid & Alkali Resistance | Good (Weak to strong acids) | Excellent (Highly resilient to all pH ranges) | PP is recommended for high pH chemical waste landfills. |
| UV Resistance (500 Hrs) | ≥ 70% strength retention | ≥ 70% (Must contain carbon black stabilizers) | PET is naturally more UV-stable than unstabilized PP. |

Adapting our manufacturing lines to process bio-derived and chemically recycled polyester resins. This reduces our dependence on fossil-fuel polymers while keeping the tensile strength and filtration performance of our geotextiles intact.
Developing new additive packages to improve resistance to UV degradation. This extends the permissible outdoor exposure window for our geotextiles during construction delays without risking structural breakdown.
Get answers to common engineering, costing, and installation questions about 140g m² non-woven geotextiles.
PET (Polyester) geotextiles offer a higher melting point, greater long-term creep resistance, and better natural UV stability. PP (Polypropylene) geotextiles are lighter, have superior chemical resistance in highly alkaline or acidic environments, and provide slightly higher tensile strength per unit weight. Choose PET for general municipal work and PP for chemical containment, landfills, or highly alkaline soils.
Pricing is based on the current cost of raw polymer chips (PET/PP), the choice of virgin or recycled raw materials, total order volume, and any special additives (like UV inhibitors). Buying directly from a manufacturer like Shandong Hongyue ensures competitive pricing by eliminating third-party distribution markups.
Our standard roll width is 2 to 6 meters, and roll lengths range from 50 to 100 meters. We can also customize roll dimensions to match your site specifications, helping to reduce on-site cutting waste and installation time.
