Comprehensive Reinforcement Solutions with Integrated Separation and Filtration for Railway Construction

In railway construction, ensuring the stability and longevity of track infrastructure over soft or variable subgrades is paramount. Naue’s Combigrid® 40/40 Q1 GRK 4 DB geocomposite offers a multifaceted solution by combining soil reinforcement with essential separation and filtration functions.

Key Features:

• Immediate Interlocking: The geogrid component provides immediate interlocking with cover aggregates, enhancing load distribution and reducing deformation.
• Chemical and Microbial Resistance: Manufactured from high-quality materials, Combigrid® exhibits high resistance to chemical and microbial attacks, ensuring durability in diverse environmental conditions.
• Cost Efficiency: The integrated design allows for a reduction in base course thickness, leading to significant material and cost savings during construction.

By integrating reinforcement, separation, and filtration into a single product, Combigrid® simplifies installation processes and enhances the performance of railway track systems, particularly over challenging subgrades.
