High-Performance Sub-Grade Felts for Sustainable Civil Engineering
Ironteks Geotech product line comprises highly resilient non-woven needle-punched geotextile felts developed for civil infrastructure, highway networks, rail base protections, tunnel linings, slope erosion control, and municipal waste containment. Fabricated from premium polymer fibers (Polypropylene PP & Polyester PES), our felts separate soil horizons, securing drainage filtration and subgrade stabilization.
Highways, railway buffers, agricultural drainage channels, chemical waste landfills, and heavy landscaping projects represent principal fields that capitalize on Geotech's physical and hydraulic resistance.
Key Characteristics & Classifications
- Drainage & Filtration: High-porosity fiber arrangement prevents migration of soil particulates while allowing water to pass through freely.
- Mechanical Reinforcement: Distributes static and dynamic mechanical loads over larger surface areas on weak subgrades, avoiding localized sinking.
- Acid and Alkaline Resistance: High resistance to underground bacteria and chemical acids with a lifespan of more than 50 years, and strong UV protection.
