Geotextile Installation Instructions
How to install geotextile fabric
Discover the simplicity of installation with our step-by-step guide, complete with invaluable tips. In our demonstration,
Step 1 - Prep the road surface
Begin by excavating the roadway to the desired elevation. Thoroughly compact the subgrade, ensuring all air pockets are eliminated and the soil is tightly compressed for optimal results.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully roll out the geotextile fabric over the compacted subgrade, ensuring it lies smoothly without wrinkles or folds. Overlap the fabric as per engineering guidelines. Cherokee offers pre-sewn options if seam stitching is necessary. Contact your Cherokee representative for pricing on factory-seamed rolls in wider widths.
Step 3 - Sewing the geotextile fabric
On-site stitching is required for this task. Use a dual-thread lock stitch to ensure the fabric remains intact. We provide equipment for purchase or rental to facilitate stitching. Depending on engineering preferences, opt for a prayer seam, j-seam, or butterfly seam. Here, a j-seam is recommended, with dual stitches on each seam to ensure installation durability.
Step 4 - Apply Aggregate
Spread the aggregate to the designated thickness, taking care to prevent equipment from driving directly on the engineered fill. Confirm full compaction of the fill before proceeding to the final stage.
Step 5 - Lay Asphalt
With your subbase expertly laid, it's time to skillfully implement your pavement layer(s), tailored to the unique specifications of your project.

Geotextile Functions
1. Separationeparation
The geotextile's separation function is integral to road construction, preventing the mixing of different soil layers. By isolating fine subgrade soil from base course aggregates, it maintains both drainage and strength of the aggregates.
Key Areas of Application Include:
- Placement between subgrade and stone base in both unpaved and paved roads and airfields.
- Separation of subgrade in railroads.
- Intervening between landfills and stone base courses.
- Situated between geomembranes and sand drainage layers.
2. Filtration
This function ensures a balanced geotextile-to-soil system, enabling optimal liquid flow with minimal soil loss across the geotextile plane.
Geotextile porosity and permeability are crucial properties facilitating efficient infiltration.
A typical filtration application is demonstrated by the use of geotextile in pavement edge drains.
3. Reinforcement
Geotextiles, when integrated into soil, significantly enhance tensile strength akin to steel reinforcement in concrete. The soil's strength increase is achieved through these mechanisms:
- Lateral restraint via interfacial friction between geotextile and soil/aggregate.
- Enforcing an alternative higher shear strength surface for potential bearing surface failure planes.
- Providing membrane support for wheel loads.
4. Sealing
A non-woven geotextile layer, placed between existing and new asphalt layers, absorbs asphalt, transforming into a waterproofing membrane that limits vertical water flow into the pavement.
Environmental and Load Considerations:
Geotextile Innovations: Lightweight geotextiles reduce structural load and minimize environmental impact.
Reinforced Concrete Limitations: Concrete structures inherently possess a significant weight, necessitating a more substantial foundation. This increased mass not only complicates the structural base but also amplifies the environmental impact during their production process.
Maintenance and Durability Overview:
Geotextile Advantages: Geotextiles stand out with their minimal maintenance requirements over the long term, thanks to their exceptional resistance to cracking and degradation.
Challenges with Reinforced Concrete: Concrete structures often demand regular upkeep due to their susceptibility to common issues like cracking, corrosion, and other wear and tear problems.
Installation Time Efficiency:
Geotextile Benefits: The rapid installation of geotextiles significantly accelerates project timelines, enabling swift completion without compromising quality.
Reinforced Concrete Constraints: The necessity for concrete curing extends the project's timeframe, posing challenges to meeting deadlines and potentially delaying completion.
Geotextile Packing and Delivery Process:
1. Products are typically secured with packing tape. The packaging dimensions and container capacity vary according to the specific product specifications.
2. Shipment via container is tailored to meet your precise project requirements, ensuring timely and efficient delivery.
