Geotextile Installation Instructions
Guidelines for Installing Geotextile Fabric
Discover the simplicity of installation with our expert guidance and invaluable tips. In this example,
Step 1 - Prepare the Road Surface
Start by excavating the roadway to your desired elevation, ensuring the subgrade is thoroughly compacted. Remove any air pockets and tightly compact the soil for a solid foundation.
Step 2 - Unroll the Reinforcement Geotextile Fabric
Carefully roll the geotextile fabric over the compacted subgrade, ensuring it is free of wrinkles and folds. Follow the engineer's directions for fabric overlap. Cherokee can expertly pre-sew the fabric if a stitched seam is necessary. Contact your Cherokee representative for pricing on factory pre-sewn rolls in wider widths.
Step 3 - Sewing the Geotextile Fabric
For on-site stitching, ensure the fabric is seamed with a dual-thread lock stitch to prevent unraveling. Our equipment is available for purchase or rental to facilitate this process. Depending on the engineer's discretion, choose between a prayer seam, j-seam, or butterfly seam. In this scenario, we employ a j-seam, recommending two stitches per seam to prevent failure during installation.
Step 4 - Apply Aggregate
Carefully layer your aggregate to the specified thickness, ensuring no equipment drives directly on the engineered fill. Confirm full compaction of the fill before proceeding to the final step.
Step 5 - Lay Asphalt
With your subbase securely in place, you are now primed to lay your pavement layer, or layers, tailored to the specific requirements of your project. This marks a pivotal step towards the completion of a robust and durable pavement structure.

Geotextile Functionalities
1. SeparationFunctionality
The separation function of geotextile is integral in road construction, preventing the intermixing of different soil types. For instance, it separates fine subgrade soil from aggregate base courses, preserving the aggregate's drainage capability and structural integrity.
Applicable Areas Include:
- Between subgrade and stone base in both unpaved and paved roads, as well as airfields, offering critical separation and support.
- Between the subgrade layers in railroad construction, ensuring structural stability and longevity.
- In landfill setups, between geomembranes and stone base courses, facilitating effective waste containment.
- Between geomembranes and sand drainage layers, optimizing drainage and soil preservation.
2. Filtration
Geotextile filtration maintains the equilibrium of the soil-geotextile system, enabling fluid passage while minimizing soil loss, crucial in diverse construction applications.
The inherent porosity and permeability of geotextiles are key in facilitating the filtration function, ensuring efficient liquid flow and soil retention.
A practical application of geotextile filtration is its implementation in pavement edge drains, enhancing water management and infrastructure durability.
3. Reinforcement
Integrating geotextile into soil significantly enhances tensile strength, akin to steel reinforcement in concrete, through three principal mechanisms:
- Lateral restraint is achieved via interfacial friction between the geotextile and soil or aggregate, providing substantial support.
- Redirecting potential bearing surface failures to develop alternate, stronger shear surfaces, thereby reinforcing the soil structure.
- Acting as a membrane, geotextile supports wheel loads, distributing weight and enhancing load-bearing capacity.
4. Sealing
Non-woven geotextile layers absorb asphalt, forming a waterproof membrane between existing and new asphalt layers, effectively minimizing vertical water infiltration.
Weight and Environmental Considerations:
Geotextile Advantages: Lightweight properties minimize load on structures and reduce environmental impact, making geotextile a sustainable choice for modern construction.
Reinforced Concrete Challenges: Concrete structures, by their very nature, are typically heavier. This necessitates a more robust foundational base, further exacerbating the environmental impact during their production process.
Maintenance and Durability Considerations:
Geotextile Advantages: Geotextiles require significantly less maintenance over their lifespan as they inherently resist cracking and deterioration, ensuring prolonged durability.
Characteristics of Reinforced Concrete: Reinforced concrete structures often face the inevitability of regular maintenance due to issues such as cracks, corrosion, and other prevalent problems, thus demanding ongoing attention.
Installation Timeframe:
Geotextile Installation: The swift and efficient installation of geotextiles facilitates accelerated project completion, ensuring timely deliverables.
Reinforced Concrete Installation: The curing time associated with concrete can extend project timelines, potentially affecting set deadlines and completion schedules.
