MIRAFI H2Rx
Water destroys roads. MIRAFI H2Rx protects them.
Water is one of the most destructive forces in pavement design. Infiltration into road structures weakens subgrades, creates potholes and ruts, and accelerates cracking, heaving, and long-term structural failure. These issues are especially severe in roads built over expansive clays or in regions with wet climates and freeze–thaw cycles.
MIRAFI® H2Rx is an engineered geotextile that combines separation, mechanical stabilization, and advanced moisture management in one solution. It stops water from compromising subgrade performance while increasing roadway resilience and extending pavement life, even under intense traffic and climate stress.
Stabilization and moisture control in a single layer
MIRAFI H2Rx is a high-performance moisture wicking geotextile designed specifically for road pavements and railway structures. It uses super high-tenacity polypropylene yarns to deliver a high biaxial tensile modulus at 2% strain, providing mechanical restraint in both directions.
At the same time, its proprietary capillary wicking technology draws and redirects moisture across the plane of the geotextile, rapidly draining excess water and equalizing moisture content within the subgrade. This combination reduces deformation, improves stiffness, and limits water-induced pavement distress.
Advanced wicking action
MIRAFI H2Rx’s patented wicking loops enhance in-plane drainage by actively drawing and redistributing excess moisture, even in unsaturated soils. It intercepts water before it can pool in subgrade depressions or form ice lenses during freezing conditions. The result is a dramatic reduction in potholes, frost boils, and pavement cracking.
Superior performance in expansive soils
Expansive clay subgrades swell with moisture and shrink when dry, leading to edge heaving, reflective cracking, and surface undulation. MIRAFI H2Rx addresses this by equalizing subgrade moisture during both wet and dry seasons, reducing differential heave and shrinkage. It also provides lateral tensile restraint, limiting surface cracking and maintaining pavement alignment.
Fast recovery after rainfall
Following rain, MIRAFI H2Rx rapidly removes excess water from the road base, restoring resilient modulus and preventing moisture accumulation that weakens pavements. Its integrated drainage function allows for faster road recovery and reduced post-rain maintenance.
Engineered for climate-responsive infrastructure
Whether addressing water ingress, clay subgrade behavior, or freeze–thaw damage, MIRAFI H2Rx provides a comprehensive geotextile solution for roadway water management. Its all-in-one design simplifies installation, supports long-term durability, and helps build climate-resilient roads in any environment.
Key benefits:
Wicking action for moisture control - draws and drains excess water horizontally to protect subgrades, reduce rutting, and prevent potholes.
High tensile stiffness - provides tensile restraint across both machine and cross-machine directions, minimizing deformation under load.
Subgrade moisture equalization - stabilizes expansive soils, reducing differential swelling, shrinkage, and cracking at pavement edges.
Fast recovery after rainfall - removes moisture efficiently to restore equilibrium moisture content in the basecourse, faster than conventional stabilization geotextiles.
Integrated performance - combines separation, mechanical stabilization, and subsurface water removal in one product to streamline installation and performance.
Climate-resilient design - performs under variable and extreme conditions, offering a long-term solution for wet climate road infrastructure.
