Mirafi Geotextile Fabric & Geogrid

Geotextile fabric is a continuous sheet — woven or nonwoven — that separates soil layers, filters water, and provides some reinforcement. Geogrid is a rigid, open grid of ribs and apertures that mechanically interlocks with aggregate to reinforce the soil mass itself. In short: fabric separates and filters; geogrid reinforces. Many heavy jobs use both together — a separation fabric over soft subgrade with a geogrid above it for structural support.

Mirafi 140N is a nonwoven needle-punched geotextile used for separation and filtration — most often as a filter fabric in French drains, under riprap and drainage stone, behind retaining walls, and to keep aggregate separated from soft subgrade soils. It lets water pass through while holding back fines, which prevents clogging and rutting. It's one of the most widely specified nonwoven fabrics on the market.

The BXG series (biaxial geogrid), the Miragrid XT series (uniaxial geogrid), and the MiraMesh series (biaxial geosynthetic) are geogrids, used for structural soil reinforcement in retaining walls, reinforced slopes, and roadway base stabilization. The X, HP, RSI, FW, MSCAPE, N, S, and G series are geotextile fabrics, and the MPV, MPG, MPM, MTK, and TM series are paving interlayers.

Mirafi® is a TenCate Geosynthetics brand, now produced by Solmax after its acquisition of TenCate's geosynthetics business. Many Mirafi products are manufactured in the United States, though some grades are produced elsewhere. Paramount Materials is an authorized supplier of the full Mirafi fabric and geogrid line.

Woven Mirafi fabric (X, HP, RSI, FW series) is made from flat polypropylene tapes for high tensile strength with very little stretch — it's built to carry load, so it's used for stabilization, reinforcement, and separation under heavy aggregate. Nonwoven Mirafi fabric (N, S, and G series) is needle-punched for higher water flow and cushioning, which makes it better for filtration, subsurface drainage, and protecting liners and pipe. As a rule of thumb: choose woven to carry load, nonwoven to move water.
