Solmax® Mirafi® H2Rx is a multifunctional woven geotextile made from high tenacity polypropylene yarns. It offers superior separation, mechanical stabilisation and moisture management for road pavements and railway structures.
Mirafi H2Rx has advanced moisture-wicking capabilities, which moves and dissipate soil moisture horizontally in unsaturated conditions. The added wicking loops help to absorb and remove extra moisture from the pavement.
Its textured surface also helps bond soil and prevent gravel from spreading, contributing to stronger, lasting roadways, by solving common issues with subgrade stabilisation.

WHY CHOOSE SOLMAX MIRAFI H2RX?
- Effectively separates and prevents the intermixing of subgrade soil and structural gravel layers
- Advanced wicking technology quickens moisture removal and drains moisture to prevent cracks, potholes and frost boils
- Equalises moisture content in expansive clay subgrades, preventing differential heaving and shrinkage that cause pavement stress
- High tensile modulus mechanically strengthens road pavement for longer design life
- Engineered for optimal performance under changing climate conditions and traffic stress
- Provides tensile stiffness modulus to mechanically strengthen the basecourse

FUNCTION
Drainage
Geosynthetics can act as a drain to carry fluid through less permeable soils. Ideal for use in subsoil drainage systems, can be used to dissipate pore water pressures at the base of road and railway embankments, sports fields and behind retaining walls. Facilitates surface water runoff.
Filtration
Geosynthetics can act as a filter by allowing water to move freely through while preventing the migration of fine particles. Often used to prevent soils from migrating into drainage aggregate or pipes while maintaining flow. Can also prevent soil erosion in coastal and riverbanks when used below loose stones or rocks and other material.
Reinforcement
Geosynthetics provides additional strength to soils and aggregate. Used to reinforce steep slopes, and to stabilise road or rail construction over weak and variable soils. Enables embankments to be constructed over very soft foundations and to build slopes at steeper angles than would be possible with unreinforced soil. Geosynthetics (or geogrids) are also used to bridge over voids that may develop below load bearing granular layers (roads and railways) or below cover systems in landfill applications.
Separation
Geosynthetics can be used to prevent the intermixing of soil types of different sizes in the construction of roads, railways, and embankments where the ground is soft and unstable to maintain the integrity of each material while allowing free passage of liquids or gases. Using a layer of geotextile to separate the soft ground from the fill material reduces the amount of fill required, increases the lifespan of the road or rail structure and cuts long-term maintenance costs.
Stabilisation
Improvement of the mechanical behaviour of an unbound granular material by including one or more geosynthetic layers such that deformation under applied loads is reduced by minimising movement of the unbound granular material. Stabilisation geosynthetics are predominantly applicable to the improved performance of bases and subbases of trafficked areas such as roadways, railways, airfields, and working platforms.
