Geotextile Installation Instructions
How to install geotextile fabric
Dive into our simple and efficient installation process, complete with insightful tips to ensure optimal performance and longevity. In our step-by-step guide, you'll master the installation with ease.
Step 1 - Prep the road surface
Commence by excavating the roadway to the specified elevation. Fully compact the subgrade, ensuring all air pockets are eliminated and the soil is tightly packed, laying the groundwork for a robust foundation.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully roll out the geotextile fabric over the compacted subgrade, ensuring a smooth, wrinkle-free application. Follow the engineer's directives for fabric overlaps. For added convenience, Cherokee offers pre-sewn seams. Contact your Cherokee representative for pricing on factory-seamed rolls, available in wider widths.
Step 3 - Sewing the geotextile fabric
Precision is key in job site seam stitching. Secure the fabric with a dual thread lock stitch to prevent unraveling. We provide equipment for purchase or rental. Depending on engineering specifications, choose from a variety of seams: prayer, j-seam, or butterfly. For this demonstration, we utilize a j-seam, ensuring durability with double stitching along each seam.
Step 4 - Apply Aggregate
Carefully distribute aggregate to the designated thickness, prohibiting equipment from driving directly on the engineered fill. Ensure the fill reaches optimal compaction prior to progressing to the final step.
Step 5 - Lay Asphalt
With your subbase successfully in place, you can now proceed to lay your pavement layer(s), tailored meticulously to the specific requirements of your project.

Functional Excellence: Geotextile
1. Separation
In road construction, geotextile plays a crucial role in separation, preventing the mixing of disparate soil types. By keeping fine subgrade soil apart from aggregate base courses, it maintains the drainage and strength of the aggregate, ensuring superior performance.
Geotextile Applications Include:
- Placed between subgrade and stone base in both unpaved and paved roads, as well as airfields.
- Used between subgrades in railroads.
- Applied between landfills and stone base courses for improved stability.
- Integrated between geomembranes and sand drainage layers.
2. Filtration
Ensures a balanced geotextile-to-soil system, supporting adequate liquid flow while minimizing soil loss across the geotextile's plane.
The porosity and permeability of geotextiles are pivotal in filtration, allowing effective infiltration action.
A practical application of filtration is evident in using geotextiles within pavement edge drains, as depicted above.
3. Reinforcement
Similar to steel in concrete, geotextile significantly boosts soil tensile strength through three key mechanisms:
- Providing lateral restraint via interfacial friction between geotextile and soil/aggregate.
- Redirecting potential bearing surface failure to an alternative high-strength shear surface.
- Offering membrane-based support to distribute wheel loads effectively.
4. Sealing
Non-woven geotextile layers are embedded between existing and new asphalt layers, absorbing asphalt to form a waterproofing membrane that minimizes vertical water penetration into pavement structures.
Weight and Environmental Impact Overview:
Geotextile Benefits: Lightweight geotextiles minimize structural load and lessen environmental impact, making them a sustainable choice.
Concrete Considerations: Heavier concrete structures demand a stronger base and contribute to a larger environmental footprint during production.
Maintenance and Durability:
Geotextile: Designed to stand the test of time, these materials demand minimal maintenance, offering incredible resistance to cracking and deterioration over years of use.
Reinforced Concrete: Frequent maintenance is often necessary due to the susceptibility of concrete structures to cracks, corrosion, and other typical issues.
Installation time:
Geotextile: Experience the advantage of swift project completion with the fast installation process, saving you both time and resources.
Reinforced Concrete: The necessity for concrete to cure can extend project timelines, potentially affecting your deadlines and overall efficiency.
