Geotextile Installation Instructions
How to Install Geotextile Fabric
Discover how effortlessly you can install geotextile fabric with our expert guidance and insightful tips. Join us in this example as we walk you through the process.
Step 1 - Prepare the Road Surface
Begin by excavating the roadway to your desired elevation. Ensure complete compaction of your subgrade, eliminating all air to achieve a tightly packed soil foundation.
Step 2 - Unroll the Reinforcement Geotextile Fabric
Carefully unroll the geotextile fabric over the compacted subgrade, taking care to smooth out any wrinkles or folds. Overlap the fabric as per engineer specifications. For seamless installation, Cherokee can pre-sew the fabric. Contact your Cherokee representative for pricing on factory-seamed rolls available in wider widths.
Step 3 - Sewing the Geotextile Fabric
On-site stitching is required for this project. Utilize a dual thread lock stitch to seam the fabric, preventing unthreading. We provide equipment for purchase or rental for this task. Choose from a prayer seam, j-seam, or butterfly seam under engineer guidance; in this case, a j-seam is recommended. Double stitching each seam ensures durability and installation success.
Step 4 - Apply Aggregate
Deposit your aggregate to the specified thickness, ensuring equipment avoids direct contact with engineered fill. Verify complete compaction of the fill before proceeding to the final step.
Step 5 - Lay Asphalt
With your subbase skillfully laid, you are now prepared to advance to the pavement layer, tailoring it to meet the specific demands of your project.

Functional Capabilities of Geotextile
1. Separation
The separation capability of geotextile plays a critical role in road construction by preventing the mixing of adjacent soils. For instance, it separates fine subgrade soil from base course aggregates, maintaining the drainage and strength of the aggregate material.
Prime Application Areas:
- Between subgrade and stone base in both paved and unpaved roads and airfields.
- Applied between subgrade layers in railroads.
- Positioned between landfills and stone base courses.
- Placed between geomembranes and sand drainage layers.
2. Filtration
The geotextile-to-soil system achieves a balance that supports sufficient liquid flow with minimal soil loss through the geotextile plane.
Key properties like porosity and permeability are central to the infiltration action of geotextiles.
A typical application showcasing filtration is the use of geotextile in pavement edge drains, enhancing functionality as indicated in the accompanying figure.
3. Reinforcement
Integrating geotextile into soil significantly boosts tensile strength, akin to how steel fortifies concrete. This strength augmentation occurs through three pivotal mechanisms:
- Lateral restraint achieved through interfacial friction between geotextile and soil/aggregate.
- Forcing the failure plane to develop an alternative, higher shear strength surface.
- Providing membrane-type support to wheel loads.
4. Sealing
A robust non-woven geotextile layer is embedded between existing and new asphalt layers. It absorbs asphalt, transforming into a waterproofing membrane that minimizes vertical water flow into the pavement structure.
Weight and Environmental Impact Considerations:
Geotextile: Lightweight in nature, geotextile reduces the load on existing structures, thus minimizing environmental impact.
Reinforced Concrete: Concrete structures, renowned for their weight, necessitate a more substantial foundation, resulting in an amplified environmental footprint during their production.
Maintenance and Durability Overview:
Geotextile Advantages: These innovative geotextiles demand minimal upkeep as they resist cracking and degradation, ensuring longevity and reliability over time.
Reinforced Concrete Challenges: Typically requires consistent maintenance to address issues like cracking, corrosion, and the usual wear and tear associated with concrete structures.
Installation Time Considerations:
Advantages of Geotextile: The swift installation process of geotextile materials allows for the rapid advancement of your projects, ensuring deadlines are met with ease.
Reinforced Concrete Limitations: The necessity for concrete to cure properly can extend project timelines, potentially delaying completion and affecting project scheduling.
