Mirafi® RSi-Series

Woven Geosynthetics

Mirafi RSi-Series geosynthetics are the premier solution for base course reinforcement and subgrade stabilization of Transportation, Building site development and Energy Infrastructure projects such as roadways, railways, and airports.

Key Features

TenCate develops and produces materials that deliver increased performance, reduce costs and measurable results to provide advanced solutions utilizing patent pending Mirafi ® RSi geosynthetics that make a difference. The Difference Mirafi ® RSi-Series Woven Integrated* Geosynthetics Make: |


Separation. Confinement. Water flow. Orange product identification. Superior integration*.

Reinforcement Strength:

Higher tensile modulus properties than the leading stabilization products.

Separation and Filtration:

Unique double layer construction provides an excellent separation factor with superior filtration and drainage. Uniform openings provide consistent filtration and flow characteristics of a fine to coarse sand layer.

Soil and Base Course Interaction:

Excellent soil and base course confinement resulting in greater load distribution.


Robust damage resistance for moderate to severe stress installations.

Roll Sizes:

Mirafi ® H2Ri -Series geosynthetics come in several roll sizes to fit project requirements.


Panels can be sewn together in the factory or field, providing cross-roll direction strength to facilitate installation.


Mirafi® RS280i

Mirafi® RS280i is the lightest version of the RSi-Series geotextiles. RS280i offers a cost-effective solution for light to moderate roadway conditions, including parking lots, low volume roads and other light duty pavements. RS280i offers material savings and sustainability for soft to firm subgrade conditions.

Mirafi® RS380i

Mirafi® RS380i is the dynamic, intermediate version of the RSi-Series geotextiles. A cost-effective solution for moderate roadway conditions. RS380i offers considerable material savings and improved sustainability for soft subgrades conditions.

Mirafi® RS580i

Mirafi® RS580i is the most robust version of the RSi-Series geotextiles. The RS580i provides significant material savings and increased sustainability to all roadway structures, especially in extremely soft subgrades. Utilized in a FHWA study (FHWA/MT-14-002/7712-251), RS580i outperformed the 12 other geotextile and geogrids used in the study.



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).


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.


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.


The ability of a geosynthetic to restrain lateral movement from a soil or aggregate through friction or mechanical interlock.
