Geotextile Installation Instructions
Guidelines for Installing Geotextile Fabric
Discover how straightforward the installation process is with our expert guidance. We offer practical tips to ensure success at every step. Let us illustrate with an example.
Step 1 - Prep the road surface
Begin by excavating the roadway to your desired elevation. Ensure the subgrade is fully compacted by eliminating air pockets and thoroughly tightening the soil to create a firm foundation.
Step 2 - Unroll the reinforcement geotextile fabric
Carefully roll out the geotextile fabric over the compacted subgrade, ensuring it lies flat without wrinkles or folds. Follow the engineer's guidelines for fabric overlap. For added convenience, Cherokee can pre-sew the fabric if a stitched 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 job-specific requirements, the fabric may need stitching on-site. Use a dual-thread lock stitch to secure the seams and prevent unthreading. We offer equipment available for purchase or rental to facilitate on-job stitching. Depending on the engineer's preference, select a prayer seam, j-seam, or butterfly seam. In this instance, we recommend a j-seam, ensuring two stitches per seam to avert installation failure.
Step 4 - Apply Aggregate
Place the aggregate to the required thickness, being cautious to prevent equipment from directly traversing the engineered fill. Confirm that the fill achieves full compaction prior to proceeding to the final step.
Step 5 - Lay Asphalt
Now that your subbase is firmly in place, you're perfectly poised to commence the installation of your pavement layer, or layers, tailored to meet the specific demands of your project. This marks a pivotal step towards achieving a sturdy and reliable foundation.

Dynamic Geotextile Functionality
1. Separation
Geotextile exhibits a remarkable separation function, predominantly utilized in road construction. This feature prevents the unwanted intermixing of adjacent soils, such as keeping fine subgrade soil distinct from the aggregate base course. As a result, it maintains the vital drainage and strength characteristics of the aggregate materials.
Geotextile's Practical Applications:
- Strategically positioned between subgrade and stone base in both unpaved and paved roads and airfields.
- Effectively applied between subgrade layers in railroads.
- Utilized between landfills and stone base courses for enhanced stability.
- Implemented between geomembranes and sand drainage layers to ensure optimal performance.
2. Filtration
Geotextiles maintain a balanced geotextile-to-soil system that enables sufficient liquid flow while minimizing soil loss across the plane of the geotextile.
The porosity and permeability attributes of geotextiles are key in facilitating effective infiltration actions.
A quintessential example of the filtration function is the employment of geotextile in pavement edge drains, as depicted in the accompanying illustration.
3. Reinforcement
The introduction of geotextile to soil remarkably enhances its tensile strength, akin to how steel fortifies concrete. This strength augmentation occurs through three principal mechanisms:
- Lateral restraint via interfacial friction between geotextile and soil/aggregate.
- Encouraging the development of an alternate, higher shear strength surface for potential bearing surface failure planes.
- Providing membrane-like support to accommodate wheel loads efficiently.
4. Sealing
A strategically placed layer of non-woven geotextile is embedded between existing and new asphalt layers. This geotextile layer absorbs asphalt, forming a waterproofing membrane that significantly reduces vertical water penetration into the pavement structure.
Weight and Environmental Impact:
Geotextile Advantages: Geotextiles are lightweight, effectively minimizing the load on existing structures and substantially reducing environmental impact, making them a sustainable choice.
Considerations for Reinforced Concrete: Concrete structures, by nature, are heavier, necessitating a more robust foundation and resulting in a higher environmental footprint during production.
Maintenance and Durability:
Geotextile: Geotextiles offer the advantage of requiring minimal maintenance over their lifespan, owing to their robust design that mitigates common issues like cracking and deterioration, ensuring long-term reliability.
Reinforced Concrete: Reinforced concrete structures often demand regular upkeep due to susceptibility to cracks, corrosion, and a host of typical structural concerns, necessitating ongoing attention for sustained integrity.
Installation time:
Geotextile: The swift and efficient installation of geotextiles accelerates project timelines, helping you meet and potentially exceed your deadlines with ease.
Reinforced Concrete: The inherent requirement for concrete curing extends project completion timelines and may affect scheduling and deadline adherence.
