Additionally, it finds extensive applications across diverse fields such as hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation zones, and environmental protection projects, delivering vital functionalities like isolation, filtration, drainage, reinforcement, and protection. Technical Data
Geotextile Installations Instructions
How to install geotextile fabric
Discover how simple it is to install geotextile fabric with our easy-to-follow guide and useful tips along the way. In our demonstration,
Step 1 - Prep the road surface
Begin by excavating the roadway to your desired elevation. Ensure the subgrade is thoroughly compacted by removing all air pockets and tightening the soil completely for optimal stability.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully unroll the geotextile fabric over the compacted subgrade, ensuring that it lays flat without any wrinkles or folds. Overlap the fabric as specified by the engineer. Cherokee offers pre-sewn fabric options if a stitched seam is required. Reach out to your Cherokee representative for pricing on factory-seamed rolls available in wider widths.
Step 3 - Sewing the geotextile fabric
For this project, the fabric needs to be stitched on-site using a dual-thread lock stitch to prevent unthreading. We provide equipment for purchase or rental to ensure seamless job site stitching. Depending on the engineer's discretion, you may opt for a prayer seam, j-seam, or butterfly seam. In this example, we utilize a j-seam and recommend double stitching each seam to prevent any failures during installation.
Step 4 - Apply Aggregate
Evenly distribute the aggregate to the specified thickness, ensuring no equipment traverses directly on the engineered fill. Verify that the fill has achieved full compaction before proceeding to the final step.
Step 5 - Lay Asphalt
As you lay the foundation of your project with the subbase in place, you are now poised to embark on the next essential phase: the pavement layer. This layer, which can be singular or multiple depending on the specific requirements of your project, sets the stage for durability and longevity.

Unveiling the Functions of Geotextile
1. Separation
The separation capability of geotextile is primarily utilized in road construction, where it is crucial in preventing the mixing of two adjacent soils. For instance, geotextiles efficiently separate fine subgrade soil from the aggregates of the base course, thereby preserving drainage efficacy and maintaining the strength characteristics of the aggregate material.
Explore the Areas of Application:
- Strategically placed between subgrade and stone base in both unpaved and paved roads, as well as in airfields.
- Employed between subgrade layers in railroads for optimal performance.
- Utilized between landfills and stone base courses to enhance structural integrity.
- Placed between geomembranes and sand drainage layers for superior filtration.
2. Filtration
The geotextile-to-soil system achieves equilibrium, allowing for efficient liquid flow while minimizing soil loss across the geotextile plane.
Porosity and permeability are key properties of geotextiles that facilitate effective infiltration.
An exemplary application demonstrating the filtration function is the use of geotextile in a pavement edge drain, ensuring optimal water management.
3. Reinforcement
Introducing geotextile into soil significantly enhances its tensile strength, much like steel does for concrete. This strength gain is achieved through three primary mechanisms:
- Lateral restraint via interfacial friction between geotextile and soil/aggregate.
- Inducing the potential bearing surface failure plane to develop a stronger, alternate surface.
- Providing membrane-type support to handle wheel loads efficiently.
4. Sealing
A layer of non-woven geotextile is sandwiched between existing and new asphalt layers. The geotextile absorbs asphalt to become a waterproofing membrane, minimizing vertical water flow into the pavement structure and enhancing durability.
Weight and Environmental Considerations:
Geotextile Advantages: These materials are lightweight, minimizing the load on the existing structure while reducing the overall environmental footprint, making them a sustainable choice for modern construction.
Reinforced Concrete Considerations: Concrete structures are known for their substantial weight, necessitating a robust foundational base. Moreover, they contribute significantly to environmental impact during the production phase, due to the energy-intensive materials and processes involved.
Maintenance and Durability Insights:
Geotextile Advantages: Geotextiles promise lower maintenance demands over time, as their resilient nature is less susceptible to cracking and deterioration, ensuring longevity and stability.
Reinforced Concrete Concerns: Reinforced concrete structures may frequently require maintenance due to common issues like cracking, corrosion, and other structural vulnerabilities, leading to potential increased costs and resources.
Installation Time Efficiency:
Geotextile Installation: The rapid installation process of geotextiles facilitates quicker project completion, allowing you to adhere to tight deadlines and move forward without delays.
Reinforced Concrete Installation: The requirement for concrete curing prolongs project timelines, potentially affecting overall deadlines and delivery schedules.
Geotextile Packing and Delivery Procedure:
1. Our products are diligently tied with packing tape. The packaging dimensions and container capacity are tailored according to specific product specifications, ensuring safe and efficient transport.
2. We offer flexible container transportation options, tailored to meet the specific needs and requests of your project, ensuring timely and efficient delivery.
