MIRAFI H2Ri
MIRAFI® H2Ri Engineered moisture management for subgrade stabilization and road durability
Water undermines road performance
Water is the biggest threat to the performance and durability of roadway infrastructure. Whether it’s perched water from high water tables, capillary rise, or surface infiltration, excess moisture compromises structural integrity. It reduces the resilient modulus of the subgrade, accelerates deformation, causes rutting and potholes, and contributes to frost heave and edge cracking in expansive clays.
Conventional geosynthetics and geogrids are effective at reinforcement, but they do little to manage water movement in unsaturated conditions. Engineers are often forced to incorporate multiple drainage layers or rely on chemical stabilization methods, which add complexity, risk, and expense to roadway construction.
MIRAFI H2Ri moisture-wicking geosynthetic
MIRAFI® H2Ri actively removes water from the subgrade, even in unsaturated soils, through innovative hygroscopic wicking yarns. This high-performance geotextile is made from woven, high-tenacity polypropylene filaments integrated with patented wicking filaments. Unlike traditional drainage systems that rely solely on gravity, MIRAFI H2Ri draws water laterally via capillary action, protecting the integrity of the subgrade and extending pavement life.
MIRAFI H2Ri is ideal for subgrade stabilization in paved and unpaved roads, railway construction and ballast stabilization, airport pavements and working platforms. It also delivers outstanding performance in areas with expansive clays, frost heave challenges, and high water tables.. Whether used in road construction, highway drainage systems, or parking lots MIRAFI H2Ri delivers proven reliability and simplified installation.
In addition to moisture management, MIRAFI H2Ri provides a single solution for stabilization, soil confinement, separation, and filtration in a single layer. Its performance has been validated through full-scale testing and third-party evaluation, offering engineers a technically sound, cost-effective solution to long-term pavement durability.
Key benefits:
Subgrade stabilization: Reinforces weak subgrade soils, improves load distribution, and reduces deformation over time.
Moisture management: Manages water in both saturated and unsaturated conditions through capillary wicking, reducing the risk of subgrade failure.
Improved drainage under roads: Replaces the need for traditional drainage fill in areas with high water tables.
Frost heave mitigation: Reduces moisture migration in freeze/thaw cycles to minimize cracking and surface distress.
Integrated performance: Provides separation, filtration, and reinforcement in a single solution, thus reducing laydown area, installation time and installation cost by half.
Durability and ease of installation: Withstands installation stresses and performs across extreme environmental conditions.
Separation & filtration: Double layer construction provides varied pore sizes for excellent separation and superior filtration, interaction, and flow characteristics.
Long-term performance: Increases the performance life of the roadway in flexible pavements with mechanical and hydraulic stabilization and reduces future maintenance.
