Geotextile Installation Instructions
How to Install Geotextile Fabric
Discover the simplicity of geotextile installation with our comprehensive guide and handy tips. In our example,
Step 1 - Prep the road surface
Begin by excavating the roadway to the required elevation. Fully compact the subgrade, ensuring all air pockets are eliminated and the soil is thoroughly tightened.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully roll out the geotextile fabric over the compacted subgrade, ensuring it is smooth and wrinkle-free. Overlap the fabric according to engineering specifications. Cherokee offers pre-sewn options for seamless installations. Contact your Cherokee representative for quotes on factory-seamed rolls in wider widths.
Step 3 - Sewing the geotextile fabric
For projects requiring on-site stitching, use a dual thread lock stitch to secure seams. We offer equipment for purchase or rental for precise stitching. Engineers may choose from prayer seams, j-seams, or butterfly seams - with a j-seam recommended here. Ensure dual stitching on each seam to prevent installation failures.
Step 4 - Apply Aggregate
Lay the aggregate to the specified thickness, avoiding direct equipment contact with the engineered fill. Achieve complete compaction before proceeding to the final phase.
Step 5 - Lay Asphalt
Once your subbase is meticulously placed, you're primed and ready to lay down the pavement layer. Depending on the specific needs of your project, multiple layers may be required for optimal stability and durability.
Case Studies to Inspire Your Next Project:
Diverse Applications:
Our geotextiles are versatile, suitable for municipal environments, landscaping, and anti-seepage tasks in urban areas. They excel in metallurgy, providing anti-corrosion properties, and are essential for transportation infrastructure. Ideal for agricultural reservoir waterproofing, fisheries aquaculture, and other facilities requiring waterproofing, erosion control, and reinforcement. These geotextiles are adept at seepage water collection and the preparation of temporary tanks and special structures, ensuring comprehensive environmental protection.
Considerations for Reinforced Concrete: It is important to note that reinforced concrete may need regular maintenance due to issues such as cracking and corrosion, which are common challenges in concrete structures.
Efficient Landfill Waterproofing Solutions: Our geotextiles ensure watertight integrity in both sanitary and industrial landfills, safeguarding against leakage and environmental hazards.
Applications include agricultural reservoir waterproofing projects and fisheries aquaculture, providing robust protection and efficiency.

Understanding the Multifunctionality of Geotextiles
1. Separation
The separation function of geotextiles is crucial in road construction, effectively preventing the intermixing of adjacent soil layers. By separating fine subgrade soil from the aggregate base, geotextiles maintain the drainage efficacy and strength of the aggregate, ensuring long-lasting performance.
Key Areas of Application Include:
- Placement between subgrade and stone base in both unpaved and paved roads, as well as airfields, to enhance durability and performance.
- Utilization between subgrade layers in railroads, creating a stable and enduring foundation.
- Integration between landfills and stone base courses to secure structural integrity.
- Application between geomembranes and sand drainage layers, promoting efficient water drainage.
2. Filtration
Geotextiles achieve a fine balance in their filtration function, allowing for adequate liquid flow while minimizing soil loss, ensuring the stability of the soil system.
Critical properties like porosity and permeability are integral to the infiltration action of geotextiles, ensuring effective filtration.
A common example of the filtration function is their application in pavement edge drains, where they maintain system efficiency.
3. Reinforcement
Introducing geotextiles into soil significantly enhances its tensile strength, akin to the strengthening effect of steel in concrete. The improvement in soil strength through geotextiles occurs via three mechanisms:
- Lateral restraint is achieved through interfacial friction between the geotextile and soil or aggregate, enhancing stability.
- Geotextiles compel potential bearing surface failure planes to form alternate surfaces with higher shear strength, promoting longevity.
- They provide membrane-like support for wheel loads, distributing pressure effectively.
4. Sealing
A non-woven geotextile layer, when placed between existing and new asphalt layers, absorbs asphalt to form a waterproof membrane, effectively reducing vertical water flow into the pavement and prolonging its lifespan.
Weight and Environmental Impact Considerations:
Geotextile Advantage: Geotextiles are lightweight, significantly reducing the load on existing structures and minimizing environmental impact, offering an eco-friendly solution.
Reinforced Concrete Considerations: Concrete structures, although steadfast and reliable, inherently possess a hefty nature. This necessitates a more substantial base for support, consequently leading to a heightened environmental impact throughout their production process.
Maintenance and Durability:
Geotextile: Geotextiles stand out for their minimal maintenance requirements over time, as they are significantly less susceptible to cracking and deterioration, ensuring continued performance and reduced upkeep.
Reinforced Concrete: Reinforced concrete often demands regular maintenance due to its vulnerability to cracks, corrosion, and other prevalent issues inherent in concrete structures.
Installation time:
Geotextile: The swift installation process of geotextiles is a boon, enabling project completions at a notably accelerated pace.
Reinforced Concrete: The requisite curing period for concrete can extend the overall project timeline, potentially impacting crucial deadlines.
