What Is Non Woven Geotextile?
Non Woven Geotextile is a permeable textile material made from synthetic fibers bonded through mechanical, chemical, or thermal processes.
Manufacturers do not weave this material like woven types. Instead, they bond the fibers using needle-punched methods or heating processes to create a structure similar to strong yet flexible felt fabric.
This textile material is designed to meet various construction needs that require soil stability and water control systems. It also serves several functions, including:
Filtration, helping filter soil particles while maintaining stable water flow.
Drainage, accelerating water flow so that water ponding can be minimized.
Separation, separating soil layers to prevent mixing with construction aggregates.
Erosion protection, protecting soil structures from damage caused by water flow or environmental pressure.
Standard Non Woven Geotextile Sizes on the Market
The roll width of non woven geotextile is available in various options, ranging from several meters to more than 10 meters. However, projects in Indonesia most commonly use a 4-meter width because it is considered ideal for road construction, drainage systems, and soil stabilization.
In general, products on the market are available in widths ranging from 2–6 meters, although some manufacturers provide custom sizes according to project requirements.
In addition to width, roll length also has standard measurements. The most commonly used length is 100 meters per roll. For certain specific needs, roll lengths may range from 50–150 meters, depending on installation methods and project site conditions.
Manufacturers sell non woven geotextile in roll form to make distribution, storage, and installation more practical. This system also simplifies material requirement calculations based directly on the total project area.
Non Woven Geotextile Grammage Sizes
Each grammage level has different characteristics that affect durability, filtration capability, and soil stabilization strength.
Understanding Geotextile Grammage
Grammage is the weight measurement of geotextile per unit area, usually expressed in gsm (grams per square meter). This value indicates how dense and strong the fiber structure of the material is.
The higher the grammage, the greater the geotextile’s ability to withstand pressure, soil shear forces, and construction loads above it.
For this reason, grammage is often used as the main indicator to determine material resistance to soft soil conditions, wet areas, and heavy-load locations.
Common Non Woven Geotextile Grammage Sizes
In the global market, non woven geotextile grammage is generally expressed in gsm or oz (ounces). Below are the most commonly used classifications along with their applications.
150 gsm: This lightweight grammage is equivalent to approximately 4.5 oz. The material is typically used for light filtration and drainage needs.
200 gsm: This size is close to 6 oz and is often applied as a separation layer. The material separates subgrade soil from drainage aggregates so that the two layers do not mix.
250 gsm: This medium grammage, equivalent to about 8 oz, begins to be used for soil stabilization. The material provides additional resistance to shear forces, making it suitable for slopes, riverbanks, and areas with potential soil movement.
300 gsm: This grammage ranges from approximately 8 oz–10 oz. The geotextile functions to protect soil surfaces from heavier erosion.
400 gsm and above: This heavy category ranges from 12 oz to 16 oz and is used in heavy engineering applications.
How to Choose the Right Grammage for a Project
Below is a guide to selecting the appropriate grammage so that material usage becomes more effective.
1. Determine the Main Function in the Project
Use grammage with high porosity so water can flow without carrying soil particles. The material functions to separate two different soil layers so they do not mix. The grammage must be strong enough to maintain long-term soil structure stability.
For projects with heavy loads or unstable soil, choose high grammage with strong tensile strength to withstand pressure and pulling forces from soil layers.
2. Analyze Soil Conditions at the Site
Soil conditions are an important factor in determining material specifications. Use geotextile with high drainage capacity so water flows quickly and does not cause ponding that damages the structure.
This type of soil requires heavy grammage, typically starting from 400 gsm, to increase stability while reducing the risk of soil deformation.

3. Consider Specific Applications
Each type of project has different standard requirements. The material must have high tensile resistance to withstand vehicle loads and prevent cracking in pavement layers.
High grammage and thickness are required to protect geomembrane layers from pressure above and to prevent leakage. Use material capable of resisting soil erosion caused by water flow and wind exposure.
4. Pay Attention to Environmental Factors
The project environment also affects material performance. In areas exposed to direct sunlight, white Non Woven Geotextile is more recommended because it reflects heat and helps maintain soil temperature stability.
5. Consult Experts and Adjust to Budget
Involving geotechnical experts, experienced manufacturers, or civil engineers helps ensure grammage selection matches field technical requirements, minimizing specification errors.
Grammage selection must still align with the project budget without neglecting minimum safety standards. The right decision ensures cost efficiency while maintaining overall construction quality.
Factors Affecting the Selection of Non Woven Geotextile Size
Choosing the correct size helps ensure more efficient area coverage. Therefore, the following key factors must be understood.
1. Type of Construction Project
In highway construction, the material functions as a separation layer beneath asphalt. Geotextile with high tensile strength prevents cracking due to soil movement while improving drainage performance.
For drainage systems, the main focus is filtration capability. The material must separate soil and aggregate so water flows smoothly without clogging.
Meanwhile, slope stabilization and riverbank protection require sizes that reinforce soil structure while controlling erosion.
In landfill projects, size selection becomes critical because the material protects geomembrane layers from potential leakage.
2. Soil Conditions and Load
Moist or wet soil requires material with high drainage capacity and proper porosity so water can flow without causing ponding.
In unstable soil conditions, the material must have high tensile strength to withstand pressure from vehicles and structures above.
3. Installation Method
Using rolls with adequate length can minimize the number of joints. Too many joints may weaken construction layers and increase the risk of structural failure.
Roll width must also match the project area to ensure efficient coverage. Widths ranging from 4 meters to more than 10 meters are often used to speed up installation.
White material improves visibility during installation and reflects sunlight heat to maintain soil temperature stability. In addition, installation must consider sufficient overlap methods to maintain optimal structural integrity.
4. Material Cost Efficiency
Cost considerations are important when determining material size without compromising technical quality. Selecting rolls that match project requirements helps balance performance and budget.
The right size allows optimal material usage, reducing waste caused by excessive cutting in the field.
