Geotextile Installations Instructions
How to install geotextile fabric
Join us as we guide you through the seamless installation process, sharing a few invaluable tips along the way. In our informative example,
Step 1 - Prep the road surface
Begin by excavating the roadway to reach the desired elevation. Ensure your subgrade is compacted to perfection, thoroughly removing air to achieve tightly packed soil.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully roll out the geotextile fabric on the compacted subgrade, ensuring it remains wrinkle-free and without folds. Overlap the fabric as per engineer directives. Cherokee offers pre-sewn fabric options if a stitch seam is necessary—reach out to your Cherokee representative for pricing on factory-seamed rolls available in wider widths.
Step 3 - Sewing the geotextile fabric
For this task, on-site stitching of the fabric is required. Employ a dual thread lock stitch to secure the seams and prevent unraveling. We provide equipment for purchase or rental to facilitate on-site stitching. At the engineer's discretion, choose from a prayer seam, j-seam, or butterfly seam. In this instance, a j-seam is utilized. We recommend applying two stitches on each seam to ensure installation integrity.
Step 4 - Apply Aggregate
Distribute aggregate to the specified thickness, ensuring no equipment traverses directly on the engineered fill. Confirm full compaction of the fill before proceeding to the final step.
Step 5 - Lay Asphalt
Once your subbase is in place, you're primed for the pavement layer—whether a singular layer or multiple, as dictated by your project's specifics.
Project Case Studies for Reference:
Applications:
Our geotextiles serve a multitude of applications including municipal environmental projects, landscaping and municipal anti-seepage efforts, and metallurgy area solutions. They are ideal for anti-corrosion, transportation infrastructure, agriculture reservoir waterproofing, and fisheries aquaculture. Additionally, they are utilized in waterproofing various facilities, preventing erosion, enhancing reinforcement, collecting seepage water, and preparing temporary tanks and special structures.
Reinforced Concrete Challenges: Concrete structures often demand consistent upkeep due to common issues such as cracks and corrosion.
Landfill Waterproofing Excellence: Ensuring complete watertight integrity in both sanitary and industrial landfill environments.

The Multi-Faceted Functionality of Geotextiles
1. Separation
Geotextiles are pivotal in road construction, efficiently preventing the intermixing of adjacent soils. For instance, they separate fine subgrade soil from base course aggregates, thereby maintaining drainage and strengthening the aggregate's characteristics.
Applicable Uses Include:
- Installation between subgrade and stone base in both unpaved and paved roads, as well as airfields.
- Application between subgrade layers in railroad construction.
- Utilization between landfill sites and stone base courses.
- Positioning between geomembranes and sand drainage layers.
2. Filtration
Geotextiles create a balanced system that facilitates fluid flow while minimizing soil loss across their plane—a testament to their porosity and permeability.
The key properties of geotextiles—porosity and permeability—are vital for their infiltration capabilities.
A classic application of the filtration function is the use of geotextile in pavement edge drains, as depicted in the accompanying illustration.
3. Reinforcement
Incorporating geotextiles into soil enhances its tensile strength, much like steel embedded in concrete. This strength is achieved through three primary mechanisms:
- Lateral restraint via interfacial friction between geotextile and soil or aggregate.
- Inducing an alternative, higher shear strength surface in potential bearing failure planes.
- Providing membrane support to distribute wheel loads.
4. Sealing
A non-woven geotextile layer is embedded between existing and new asphalt, absorbing asphalt to form a waterproofing membrane that curtails water seepage into the pavement.
Weight and Environmental Considerations:
Geotextile Benefits: Geotextiles are light, which reduces structural load and minimizes environmental impact.
Reinforced Concrete Drawbacks: Concrete structures are inherently heavy, necessitating a more robust foundation and contributing to greater environmental impact during production.
Maintenance and Durability:
Geotextile: Our high-quality geotextiles are engineered for exceptional resilience, requiring minimal maintenance over time thanks to their resistance to cracking and deterioration.
Reinforced Concrete: Reinforced concrete can be susceptible to common issues like cracks and corrosion, necessitating regular and often costly maintenance.
Installation time:
Geotextile: Experience swift project completion with our geotextiles, designed for rapid installation that accelerates timelines.
Reinforced Concrete: The curing time of reinforced concrete can significantly extend project timelines, posing challenges to meeting deadlines.
