Geotextile Installations Instructions
How to install geotextile fabric
Allow us to illustrate just how effortlessly the installation process can be accomplished, while offering some valuable tips to ensure success. In our detailed example,
Step 1 - Prep the road surface
Commence by excavating the roadway to the desired elevation, followed by meticulous compaction of the subgrade. Ensure all air pockets are eliminated and the soil is thoroughly tightened.
Step 2 - Unroll the reinforcement geotextile fabric
Gently roll out the geotextile fabric on the compacted subgrade, ensuring it is smooth and free from wrinkles or folds. Follow the engineer's guidelines for fabric overlap. Cherokee can pre-sew the fabric for you if stitching 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, the fabric requires onsite stitching. Secure the fabric using a dual-thread lock stitch to prevent unraveling. We offer equipment for purchase or rental to facilitate stitching on-site. Depending on the engineer's preference, opt for a prayer seam, j-seam, or butterfly seam. In this instance, we will use a j-seam. We recommend stitching each seam twice to prevent any failure during installation.
Step 4 - Apply Aggregate
Carefully lay your aggregate to the specified thickness, ensuring no equipment traverses the engineered fill. Confirm that the fill achieves full compaction before proceeding to the final step.
Step 5 - Lay Asphalt
With your subbase perfectly in place, you are now poised to advance to the next critical phase: laying down your pavement layer. Whether it involves a single layer or multiple layers, this step is dependent on the specific requirements of your project. Prepare to witness the magic of transformation as your groundwork lays the foundation for a seamless pavement installation.

Geotextile Functionality Unveiled
1.Separation
The geotextile's separation function is paramount in road construction, where it prevents the mixing of two adjacent soil types. By effectively separating fine subgrade soil from the aggregates of the base course, it safeguards the drainage and strength properties of the aggregates, ensuring a durable and stable road structure.
Some of the applicable areas are:
- Applied between subgrade and stone base in both unpaved and paved roads and airfields, ensuring enhanced stability and longevity.
- Strategically placed between subgrade layers in railroads for optimal performance.
- Utilized between landfills and stone base courses to ensure integrity and functionality.
- Integrated between geomembranes and sand drainage layers for superior separation and filtration.
2.Filtration
The geotextile-to-soil system achieves equilibrium, allowing for sufficient liquid flow while minimizing soil loss across the geotextile plane. This essential filtration function is critical to maintaining system efficiency and longevity.
Key properties such as porosity and permeability are central to the geotextile's infiltration action, enhancing its filtration efficiency.
An exemplary application showcasing the filtration function is the deployment of geotextile in pavement edge drains, effectively managing water flow as depicted in the accompanying diagram.
3.Reinforcement
Incorporating geotextile into soil significantly boosts its tensile strength, akin to the way steel fortifies concrete. This remarkable strength enhancement is achieved through three primary mechanisms:
- 1. Lateral restraint is provided via interfacial friction between the geotextile and soil/aggregate, reinforcing the structure.
- 2. It compels the potential bearing surface failure plane to develop an alternate, higher shear strength surface, enhancing stability.
- 3. Geotextile offers membrane-like support to wheel loads, effectively distributing weight and maintaining structural integrity.
4. Sealing
The innovative use of a non-woven geotextile layer, sandwiched between existing and new asphalt layers, transforms it into a waterproofing membrane. This remarkable property minimizes the vertical flow of water into the pavement structure, ensuring long-term durability and protection.
Weight and Environmental Impact:
Geotextile: Engineered for lightweight efficiency, geotextiles minimize the structural load and significantly reduce environmental impact, making them an eco-friendly choice.
Reinforced Concrete: Concrete structures, known for their weight and density, demand a strong foundation, which can lead to an increased environmental footprint during the production phase.
Maintenance and Durability:
Geotextile: Require far less maintenance over the years, as these materials are designed to resist cracking and degradation, ensuring longevity and reliability.
Reinforced Concrete: These structures may necessitate consistent upkeep due to vulnerabilities such as cracks and corrosion, which are prevalent in concrete applications.
Installation time:
Geotextile: The swift and efficient installation process significantly accelerates project timelines, allowing for much quicker completion.
Reinforced Concrete: The time-consuming curing process of concrete can extend project durations, potentially leading to deadline extensions.
