Mirafi® H2Ri 
Mirafi® H2Ri is a revolutionary continuous moisture management system for base course reinforcement and subgrade stabilization of Transportation, Site Development, and Energy Infrastructure projects such as roads, railways, and airports.
Functions
Moisture Management
The ability to move a liquid through soil-geotextile system by capillary action, neither relying on gravity nor a positive hydraulic gradient.
Reinforcement
The synergistic improvement of a total system’s strength created by the introduction of a reinforcing geosynthetic (that is good in tension) into a soil and/or aggregate system (that is good in compression but poor in tension).
Separation
The placement of a flexible, porous geotextile between dissimilar materials so that the integrity and intended functions of both materials remain intact or are improved.
Drainage
The equilibrium soil-to-geotextile system that allows for adequate movement of a liquid in the plane of the geotextile over the service lifetime of the application.
Confinement
The ability of a geosynthetic to restrain lateral movement from a soil or aggregate through friction or mechanical interlock.
Filtration
The equilibrium soil-to-geotextile system that allows for adequate movement of a liquid across the plane of the geotextile with limited soil loss over the service lifetime of the application.

A new bridge was being constructed over the Missouri River where saturated soil conditions required the need to remove water from under the pavement section at the bridge approaches.
