Technical Data
Geotextile Installation Instructions
How to install geotextile fabric
Discover how seamless geotextile installation can be with our straightforward guide and handy tips. Follow along in our example,
Step 1 - Prep the road surface
Begin by excavating the roadway to the desired elevation. Ensure complete compaction of your subgrade by eliminating air pockets and thoroughly tightening the soil for optimal results.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully unroll the geotextile fabric onto the compacted subgrade, ensuring it lies flat without wrinkles or folds. Overlap as per engineering directives. Cherokee offers pre-sewn fabric options for stitch seams—contact your Cherokee representative for pricing on wider, factory-seamed rolls.
Step 3 - Sewing the geotextile fabric
On-site fabric stitching is required for this task. Employ a dual-thread lock stitch to secure the seams, preventing unraveling. Equip yourself with our available purchase or rental stitching equipment. Choose among prayer, j-seam, or butterfly seams at the engineer's discretion. Here, we demonstrate a j-seam, recommending dual stitches on each seam to ensure installation integrity.
Step 4 - Apply Aggregate
Spread the aggregate to the prescribed thickness, making sure to avoid direct equipment contact with the engineered fill. Achieve full compaction before proceeding to the final step.
Step 5 - Lay Asphalt
After establishing your subbase, you're all set to proceed with the pavement layer. Depending on the project specifications, this might be a singular or multiple-layer process, tailored to achieve durability and optimal performance.

Exploring the Functions of Geotextile:
1. Separation
Geotextiles play a crucial role in road construction by preventing the mixing of different soil layers. By keeping fine subgrade soil and aggregate materials distinct, they maintain drainage and enhance the strength of the base course. This separation is vital for preserving structural integrity and prolonging the lifespan of the infrastructure.
Ideal application scenarios include:
- Installation between subgrade and stone base in both unpaved and paved roadways, as well as airfields.
- Utilization between subgrade layers in railroads for enhanced stability.
- Placement between landfills and stone base courses for optimal separation.
- Application between geomembranes and sand drainage layers to ensure proper separation.
2. Filtration
Our geotextiles provide a balanced geotextile-to-soil system, promoting efficient liquid flow while minimizing soil loss. This filtration capability supports sustainable designs and enhances durability.
Key properties like porosity and permeability allow geotextiles to facilitate infiltration effectively, offering both strength and adaptability.
A notable example of the filtration function is the implementation of a geotextile in a pavement edge drain, ensuring proper drainage and longevity.
3. Reinforcement
Introducing geotextiles in soil construction projects markedly enhances tensile strength, akin to how steel fortifies concrete. The resulting strength increase stems from three primary mechanisms:
- Lateral restraint through interfacial friction between geotextile and soil/aggregate, providing stability.
- Encouraging the development of an alternate high shear strength surface, enhancing durability.
- Supporting wheel loads via a membrane-like action, distributing and minimizing pressure.
4. Sealing
A non-woven geotextile layer, when impregnated between existing and new asphalt layers, becomes a waterproof barrier. This sealing minimizes water infiltration into the pavement, enhancing its longevity and durability.
Weight and Environmental Impact Assessment:
Geotextile Characteristics: Geotextiles are lightweight, reducing the load on existing structures and offering a lower environmental footprint compared to traditional materials.
Reinforced Concrete Traits: Concrete structures, due to their heavier nature, require a more substantial base and involve greater environmental impact during their production process.
Maintenance and Durability:
Geotextile: Our Geotextile requires minimal maintenance over the years due to its superior resistance to cracking and deterioration, ensuring enduring performance and cost-effectiveness.
Reinforced Concrete: Reinforced concrete may involve frequent upkeep as it is susceptible to cracks, corrosion, and other prevalent structural issues, demanding regular attention.
Installation time:
Geotextile: The swift and straightforward installation of Geotextile accelerates project timelines, allowing for faster completion and greater project efficiency.
Reinforced Concrete: The necessity of concrete curing can significantly delay project completion, posing challenges to your schedule management.
