Geotextile Installations Instructions
How to install geotextile fabric
Let us guide you through the straightforward installation process, providing some valuable 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 fully compacted, with all air expelled and the soil thoroughly compacted to achieve a stable foundation.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully roll out the geotextile fabric on the compacted subgrade, ensuring it remains free of wrinkles and folds. Overlap the fabric as specified by the engineer. Cherokee offers pre-sewn fabric options if a stitched seam is necessary. Contact your Cherokee representative for pricing on factory-seamed rolls available in wider widths.
Step 3 - Sewing the geotextile fabric
The task requires the fabric to be stitched on-site. Ensure the fabric is seamed with a dual-thread lock stitch to prevent unraveling. Equipment for stitching is available for purchase or rental. Based on the engineer's advice, you can opt for a prayer seam, j-seam, or butterfly seam. In our example, a j-seam is employed. We recommend two stitching passes per seam to prevent installation failures.
Step 4 - Apply Aggregate
Distribute the aggregate to the required thickness, ensuring that no vehicles drive directly on the engineered fill. Confirm that the fill achieves full compaction before moving to the final step.
Step 5 - Lay Asphalt
Congratulations on successfully laying your subbase! You're now poised to embark on the next phase of your project: the pavement layer. Depending on your specific project needs, you may opt for one or multiple layers, ensuring a robust and durable surface.

Unveiling Geotextile Functionality
1. Separation
Geotextile's separation function is pivotal in road construction, effectively preventing the intermingling of adjacent soil layers. For instance, it separates fine subgrade soil from base course aggregates, preserving the drainage capabilities and strength of the aggregate material.
Broad Application Areas Include:
- Positioned between subgrade and stone base in both unpaved and paved roads and airfields.
- Situated between subgrade layers in railroads.
- Installed between landfills and stone base courses.
- Placed between geomembranes and sand drainage layers.
2. Filtration
Geotextiles maintain a delicate equilibrium, allowing for optimal liquid flow while minimizing soil loss across their plane, thanks to their porosity and permeability, which are crucial for infiltration.
Porosity and permeability constitute the core properties of geotextiles, enhancing their infiltration capabilities.
A classic example of the filtration function in action is geotextile use in pavement edge drains, ensuring efficient water management.
3. Reinforcement
Geotextiles bolster soil strength akin to steel in concrete, achieved through lateral restraint via interfacial friction, fostering an alternative higher shear strength surface, and membrane support for wheel loads.
- Lateral restraint is achieved through interfacial friction between the geotextile and soil/aggregate.
- Compels the potential failure plane to seek a new, stronger shear strength surface.
- Provides membrane-type support for wheel loads.
4. Sealing
Non-woven geotextiles impregnated between asphalt layers form a waterproofing membrane, curtailing vertical water flow into pavement structures.
Weight and Environmental Impact: A Comparison
Geotextile: Remarkably lightweight, geotextiles minimize structural load and significantly reduce environmental impact.
Reinforced Concrete: Concrete structures, due to their heft, demand robust foundational support and entail greater environmental impact during production.
Maintenance and Durability:
Geotextile: Our Earthwork Geotextiles are engineered to require minimal maintenance over time, significantly reducing the likelihood of cracking and deterioration. This ensures your projects remain robust and functional for longer periods, offering peace of mind and saving costs on upkeep.
Reinforced Concrete: Reinforced concrete structures may necessitate ongoing maintenance due to their susceptibility to issues such as cracking, corrosion, and other common structural challenges. Regular upkeep is often essential to maintain their integrity and prolong their lifecycle.
Installation time:
Geotextile: Experience swift and efficient project completion with our geotextiles. Their quick installation process enables you to meet project timelines with ease, allowing resources to be reallocated to other priorities while minimizing disruption.
Reinforced Concrete: The necessity for concrete curing can significantly delay project timelines, imposing extended completion times which may impact deadlines and project scheduling. Considerations for these delays are crucial in the planning phase.
