Mirafi® RSi | Geofabrics

    Mirafi RSi are the first truly multifunctional woven geotextiles developed to ensure reinforcement, separation, drainage and filtration and superior material interaction between the aggregate layers in an integrated way. The result is an assured significant improvement in road/subgrade performance with the added benefit of reduced sub base material volumes when constructing over soft soils.
