High-stiffness geotextile for reliable subgrade reinforcement

Built for performance under pressure

Infrastructure built over weak subgrades often suffers from rutting, settlement, and long-term degradation. When performance depends on stiffness, strength, and dimensional stability under load, reinforcement must deliver both immediate and enduring resistance to deformation.

MIRAFI^® HMi is specifically engineered for such high-demand environments. With a stiffness modulus of 1100 kN/m and extremely low elongation at high tensile strengths, it reinforces granular layers while reducing rut depths and settlement. This translates into longer design life, reduced maintenance, and increased structural integrity in access roads, paved and unpaved roads, railways, and embankments. 

Multi-functional performance in one product

MIRAFI HMi combines reinforcement, separation, and filtration in a single, recyclable polypropylene geotextile. Its specialized weave and inwoven product name ensure easy on-site identification, while its excellent packing efficiency allows more material to be delivered per truckload, reducing transportation costs and carbon footprint.

Used in standard or challenging site conditions, MIRAFI HMi:

• 

  Enhances load distribution

• 

  Prevents intermixing of soil layers

• 

  Allows free water drainage without loss of fill material

• 

  Maintains mechanical and friction characteristics over time

Independent studies confirm that MIRAFI HMi can significantly reduce the thickness of granular layers required for the same performance, optimizing material use and reducing CO₂ emissions. In tests, it outperforms woven and extruded geogrids in stiffness at low deformation, enabling engineers to maintain bearing capacity with less fill.
