What is Geotextile Fabric?
Geotextile fabric is a permeable textile material made from synthetic fibers such as polypropylene or polyester. It is designed to enhance the performance of soil by providing separation, filtration, drainage, and reinforcement. There are two primary types of geotextile fabrics:
Woven Geotextile Fabric: Made by weaving polypropylene or polyester fibers together, this type of geotextile fabric is strong and ideal for applications requiring high tensile strength, such as road construction and soil reinforcement.
Non-Woven Geotextile Fabric: Produced through needle-punching or heat-bonding processes, non-woven geotextile fabric is used for filtration, drainage, and separation applications.

Main Applications of Geotextile Fabric
Geotextile fabric is used in a wide range of applications in construction and civil engineering:
Soil Stabilization:
Geotextile fabric provides stability to weak soils by distributing loads and preventing the mixing of different soil layers. It is commonly used in the construction of roads, railways, and embankments.
Erosion Control:
It prevents soil erosion by protecting slopes and embankments from wind and water erosion. It is often used in coastal protection and riverbank stabilization projects.
Drainage Systems:
Geotextile fabric facilitates the flow of water while preventing soil particles from clogging drainage systems. It is widely used in subsurface drainage systems and retaining wall backfill.
Filtration:
It acts as a filter by allowing water to pass through while retaining soil particles. This application is critical in preventing soil loss in various hydraulic engineering projects.
Separation:
Geotextile fabric separates different layers of soil, preventing contamination and ensuring the integrity of the construction structure. It is used in the construction of roads and pavements.
How to Calculate Geotextile Fabric Usage and Cost for Construction Sites
Calculating the required amount of geotextile fabric and its cost for a construction project involves several steps:
Calculate the Area to be Covered:
Measure the length and width of the area where the geotextile fabric will be installed.
Formula: Area = Length × Width
Example: For a road project with a length of 200 meters and a width of 5 meters, the area would be 200 × 5 = 1000 m².
Factor in Overlap and Wastage:
Geotextile fabric should be installed with a minimum overlap of 0.3 to 0.5 meters. Add 5-10% to the total area to account for overlaps and potential wastage.
Formula: Total Area = Area + (Area × Overlap Factor)
Example: For a 1000 m² area, with a 10% overlap factor, the total area would be 1000 + (1000 × 0.1) = 1100 m².
Determine the Quantity of Rolls Required:
Based on the roll width and length, calculate the number of rolls required.
Formula: Number of Rolls = Total Area / (Roll Width × Roll Length)
Example: If using rolls that are 2 meters wide and 50 meters long, each roll covers 100 m². Therefore, the number of rolls required is 1100 / 100 = 11 rolls.
Calculate the Cost of Geotextile Fabric:
Multiply the total area by the unit price of the chosen geotextile fabric specification.
Formula: Total Cost = Total Area × Unit Price
Example: If the chosen fabric costs $1.50/m², then the total cost would be 1100 × 1.50 = $1650.
Cost of Procuring Geotextile Fabric from the Factory
Purchasing geotextile fabric directly from the factory can result in significant cost savings, especially for large projects. Factors influencing the cost from the factory include:
Quantity Ordered:
Bulk orders typically receive discounts, reducing the overall cost per square meter.
Customization:
Factories can produce geotextile fabric in specific sizes, thicknesses, and strengths based on project requirements. Custom orders may have a different cost structure compared to standard products.
Shipping and Logistics:
The cost of transporting the fabric from the factory to the construction site can vary based on the location and the volume of the order. Factoring in shipping costs is crucial for accurate budgeting.
Payment Terms:
Factories may offer better pricing for upfront payments or long-term contracts. Negotiating payment terms can help in managing project cash flow effectively.
Conclusion
Understanding the cost of geotextile fabric is essential for efficient project planning and budgeting. By considering the specifications, main applications, and accurate usage calculation, project managers can estimate the total cost and select the right type of geotextile fabric for their needs. Procuring geotextile fabric directly from the factory can offer cost advantages, but it's important to consider factors such as quantity, customization, and logistics. For detailed pricing and further assistance, it is recommended to consult with reputable suppliers or manufacturers.
