Mirafi® S Filter Fabric

Mirafi® S filter fabric plays a significant role in the collection of liquids in waste containment systems. This nonwoven geotextile is used in critical subsurface drainage systems, permanent erosion control, soil separation, and other geomembranes in landfill construction. Similar to the Mirafi® N-Series, the S-Series differs in material weight and thickness. The S-Series is available in 6 oz. to 16 oz. weights, and deliver excellent strength and abrasion resistance, as well as withstanding installation and application stresses. Mirafi® filter fabric provides exceptional durability, along with high puncture resistance, permittivity, and transmissivity.

Mirafi® Filter Fabrics


Mirafi® S-Series nonwoven geotextiles are used in a wide variety of ways in the environmental market, including separation, filtration, or protection applications. The polypropylene, nonwoven fabric prevents clogging of collection pipes and drainage collections, making it ideal for Environmental, Natural Resources and Energy Infrastructure projects. These nonwovens are constructed to easily conform to ground or trench surfaces, ensuring problem free installation. The high flow through and soil retention rate makes the S series the perfect choice for civil engineering applications. Mirafi® geotextiles eliminate the difficulty of determining the aggregate gradation required to match soil conditions, assuring your constructed in-place drainage system will provide effective filter performance.

Mirafi® Filter Fabric Applications


Mirafi® filter fabric is primarily used for protection in Environmental, Natural Resources and Energy Infrastructure projects. This includes liner protection in solid waste landfills, fracking ponds, and other water management systems. These heavyweight, nonwoven fabrics are effective in critical subsurface drainage systems, permanent erosion control, soil separation, and geo-membrane liner protection in landfills. Mirafi® filter fabrics also assist in maintaining an opening for gases to escape from below liner systems. Other uses for nonwoven fabrics in landfill applications are:  leachate collection/removal systems and gas collection and venting systems.
