TechTex C - Needle Punched Nonwoven Polypropylene Geotextile
TechTex C
TechTex CTechTex C is a black nonwoven geotextile manufactured from 100% virgin high-strength polypropylene fibers through a needle-punching and heat-setting process. Engineered for superior mechanical strength, high water permeability, and long-term durability, it delivers reliable performance in drainage, filtration, separation, and reinforcement applications. Available in a wide range of technical specifications to meet project-specific requirements, TechTex C adapts to challenging ground conditions and harsh climates. It provides effective and long-lasting solutions for road construction, railway infrastructure, civil engineering, environmental protection, and geotechnical engineering projects.
TechTex C Functions
TechTex© C combines four different geotechnical functions in a single product. In landfill sites and mining waste areas it is placed over geomembranes to protect them against puncture and damage. In stream rehabilitation and flood protection structures it provides separation and drainage beneath the armour layer. In highway drainage trenches it wraps the gravel layer to prevent fine soil particles from entering the system and performs the filtration function.
Drainage
TechTex© C supports the controlled discharge of water and contributes to the efficient operation of drainage systems. It helps protect structures against the adverse effects caused by water.
Filtration
With its permeable structure, TechTex© C allows water to pass through while filtering fine soil particles, helping prevent clogging within drainage systems. This ensures long term filtration efficiency and maintains reliable drainage performance throughout the service life of the application.
Reinforcement
By distributing loads over a wider area, TechTex© C contributes to improving the bearing capacity of the soil. It helps reduce soil deformation and enhances the overall structural performance and stability of engineering applications.
Separation
By preventing the intermixing of different soil layers, TechTex© C helps maintain the functional performance of construction materials. It supports the long term durability, stability and reliable operation of foundation and infrastructure systems.
High Tensile and Puncture Strength at Low Weight
Despite its low unit weight, TechTex© C offers high tensile and puncture strength. By separating soil layers it reduces the need for fill material and lowers the amount of excavation required to reach the target profile. This delivers savings both during construction and throughout the service life of the structure on the maintenance side.

Frequently Asked Questions
1. What Is TechTex C?
TechTex© C is a black nonwoven geotextile produced by needle punching 100% pure polypropylene fibres and applying thermal treatment. It delivers four fundamental geotechnical functions in a single product: drainage, filtration, separation and reinforcement.
2. Which Functions Does TechTex C Perform?
It provides drainage by supporting the controlled discharge of water, acts as a filter by retaining fine soil particles thanks to its permeable structure, provides separation by preventing different soil layers from mixing, and contributes to the bearing capacity of the soil by distributing loads over a wider area.
3. Can TechTex C Be Used for Geomembrane Protection?
Yes. In landfill sites and mining waste areas it is placed over the geomembrane to protect it against the risk of puncture and damage from the overlying fill material. The required weight for this application is determined according to the particle size of the material above and the load level.
4. What Is the Difference Between TechTex C and TechTex UV?
Both products are needle punched nonwoven polypropylene geotextiles. TechTex© UV is produced with UV resistance brought to the forefront for applications that will remain exposed for extended periods. TechTex© C is designed for standard buried applications and is preferred in projects where the material is covered shortly after installation.
5. Is TechTex C Resistant to Chemical Effects?
Polypropylene raw material is resistant to acids, alkalis and micro organisms found in soil. This allows TechTex© C to maintain its structural integrity over long periods in the environment where it is buried. For use in aggressive chemical environments we recommend that project conditions be evaluated with our technical team beforehand.
6. In Which Weights Is TechTex C Produced?
TechTex© C can be produced in different weights and technical specifications to suit project requirements. To determine the product type suited to your needs you can review the technical values in the datasheet section or contact us directly.
