- The polypropylene needle-punched non-woven geotextile is a cornerstone in the sliding layer between CRTS slab ballastless track and beam surfaces of passenger-dedicated railways, and as an isolation layer in friction contexts. Its versatility extends to hydropower, highways, railways, ports, airports, sports venues, tunnels, beaches, reclamation projects, environmental protection efforts, and more, where it serves functions such as isolation, filtration, drainage, reinforcement, and protection. Technical Data
Geotextile Installation Instructions
How to install geotextile fabric
Discover the straightforward process of installing geotextile fabric, complete with valuable tips for seamless application. In our demonstration,
Step 1 - Prep the road surface
Begin by excavating the roadway to your desired elevation. Ensure the subgrade is fully compacted, meticulously removing air and achieving a tightly consolidated soil foundation.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully unroll the geotextile fabric over the compacted subgrade, ensuring it lies smooth without wrinkles or folds. Follow your engineer's guidance on fabric overlap. For precision seam requirements, Cherokee can pre-sew the fabric; consult your Cherokee representative for pricing on factory-seamed rolls available in wider widths.
Step 3 - Sewing the geotextile fabric
This project necessitated on-site fabric stitching. Utilize a dual-thread lock stitch to secure seams against unthreading. We offer equipment for purchase or rental for on-site stitching. Based on engineer preference, choose from a prayer seam, j-seam, or butterfly seam; in this case, a j-seam is employed. Double stitching each seam is recommended to ensure durability throughout the installation.
Step 4 - Apply Aggregate
Distribute your aggregate to the predetermined thickness, ensuring no equipment traverses the engineered fill. Confirm full compaction of the fill before proceeding to the final step.
Step 5 - Lay Asphalt
With the subbase now perfectly positioned, you are poised to advance to the pavement layer. Depending on the unique specifications of your project, multiple layers may be required to achieve the desired finish and durability.

Discover the Multifunctional Abilities of Geotextile
1. Separation
Geotextile's separation functionality is pivotal in road construction, preventing the undesirable intermixing of adjacent soils. By maintaining a distinct barrier between fine subgrade soil and aggregate materials in the base course, geotextile enhances both drainage and structural integrity, ensuring longevity and resilience for roadways.
Some of the applicable areas are:
- Embedded between the subgrade and stone base in both unpaved and paved roads as well as airfields.
- Implemented between the subgrade and ballast layers in railroads.
- Strategically placed between landfills and stone base courses to ensure stability.
- Inserted between geomembranes and sand drainage layers to facilitate optimal performance.
2. Filtration
Our geotextile expertly manages the equilibrium of the geotextile-to-soil system, enabling sufficient liquid flow while minimizing soil loss across the geotextile plane.
Porosity and permeability are the cornerstone properties that empower geotextiles to execute flawless infiltration actions.
A prime example of geotextile's filtration prowess is its use in pavement edge drains, maintaining the structural integrity as depicted above.
3. Reinforcement
Integrating geotextile into the soil significantly boosts its tensile strength, akin to the reinforcement steel provides to concrete. This remarkable strength enhancement is achieved through three primary mechanisms:
- Lateral restraint by creating interfacial friction between geotextile and soil/aggregate.
- Inducing the development of an alternative, higher shear strength surface along potential failure planes.
- Providing membrane-type support to effectively distribute wheel loads.
4. Sealing
A non-woven geotextile layer is skillfully embedded between existing and new asphalt layers. This geotextile absorbs asphalt, transforming into a waterproofing membrane that significantly curtails vertical water flow into the pavement structure.
Evaluating Weight and Environmental Impact:
Geotextile: The inherent lightness of geotextiles reduces the load on existing structures, thereby diminishing environmental impact.
Reinforced Concrete: Concrete constructions are inherently heavier, necessitating a sturdier base and escalating environmental impact during their production.
Maintenance and Durability:
Geotextile: Geotextiles are ingeniously designed to significantly reduce the need for maintenance over time. Their unique composition makes them less susceptible to common issues such as cracking and deterioration, ensuring long-lasting durability and reliability.
Reinforced Concrete: Reinforced concrete, though robust, often necessitates regular maintenance to address common issues like cracks and corrosion, which can arise in concrete structures. This can involve time-consuming and costly repairs over the lifespan of the material.
Installation time:
Geotextile: Thanks to its innovative design, geotextile installation is remarkably swift, allowing projects to be completed in record time, meeting tight deadlines and accelerating overall progress.
Reinforced Concrete: The curing process of concrete can introduce significant delays in project completion, posing challenges to meeting project timelines and potentially impacting overall deadlines.
