Technical Data
Geotextile Installation Instructions
How to install geotextile fabric
Allow us to demonstrate the simplicity of geotextile installation, complete with insightful tips along the way. In our example,
Step 1 - Prep the road surface
Begin by excavating the roadway to the desired elevation. Ensure the subgrade is fully compacted by removing all air pockets and tightening the soil thoroughly, setting a robust foundation for the geotextile.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully roll out the geotextile fabric over the compacted subgrade, ensuring it's smooth and wrinkle-free. Overlap the fabric as per engineering guidelines. Cherokee offers pre-sewn fabric options for projects requiring seam stitching. Contact your Cherokee representative for pricing on factory-seamed, wider-width rolls.
Step 3 - Sewing the geotextile fabric
When field stitching is necessary, employ a dual-thread lock stitch to secure seams and prevent unthreading. Choose from prayer, j-seam, or butterfly stitch options at the engineer's discretion. For this project, a j-seam is recommended with dual stitching to ensure robust installation integrity.
Step 4 - Apply Aggregate
Distribute aggregate to the specified thickness, avoiding direct equipment contact with the engineered fill. Ensure full compaction of the fill before proceeding to the final step.
Step 5 - Lay Asphalt
Having successfully laid your subbase, you're now primed for the pivotal next step: installing your pavement layer (or layers, contingent upon the project's unique requirements and specifications).
Illustrative Project Case Studies for Your Reference:

Comprehensive Geotextile Functions and Benefits
1. Separation
Geotextile excels in separation tasks, especially in road construction, by preventing the mixing of adjacent soils. For instance, it effectively isolates fine subgrade soil from base course aggregates, maintaining the drainage and structural integrity of the aggregates.
Applicable Areas Include:
- Separation between subgrade and stone base in both unpaved and paved roads, as well as airfields.
- Between subgrade layers in railroad construction.
- Situated between landfills and stone base courses.
- Placed between geomembranes and sand drainage layers for optimal performance.
2. Filtration
Maintains equilibrium within the geotextile-to-soil system, allowing sufficient liquid flow while curtailing soil loss across the geotextile plane.
Porosity and permeability are crucial geotextile properties that facilitate its filtration role.
A typical filtration application is using geotextile in pavement edge drains, as visually depicted above.
3. Reinforcement
Incorporating geotextile in soil significantly enhances tensile strength, paralleling the reinforcing effect of steel in concrete. This strength increment in soil occurs through three mechanisms:
- Lateral restraint achieved through interfacial friction between geotextile and soil or aggregate.
- Promotes the development of a higher shear strength surface by altering the potential bearing surface failure plane.
- Provides membrane-like support for wheel loads, enhancing overall structural resilience.
4. Sealing
A non-woven geotextile layer is infused between existing and new asphalt layers. It absorbs asphalt to form a waterproof membrane, minimizing water penetration into the pavement structure.
Weight and Environmental Impact Considerations:
Geotextile Advantages: Geotextiles are lightweight, effectively reducing the load on existing structures and minimizing environmental impact.
Reinforced Concrete Challenges: Heavier in nature, concrete structures require robust foundations and contribute more significantly to environmental impact during production.
Maintenance and Durability:
Geotextile: Our 100g geotextiles boast exceptional durability, requiring minimal maintenance. These innovative materials resist cracking and deterioration, ensuring long-lasting reliability and performance.
Reinforced Concrete: Traditional reinforced concrete may demand frequent maintenance due to its susceptibility to cracking, corrosion, and other structural issues, which can compromise integrity over time.
Installation time:
Geotextile: The swift installation of our geotextiles accelerates project timelines, enabling faster completion and efficient workflow without compromising quality.
Reinforced Concrete: The extended curing time required for concrete can significantly delay project completion, potentially affecting critical deadlines and operational schedules.
