Filtrexx History: living proof of how one clever idea can change entire industries.


Rod Tyler, a graduate of The Ohio State University and a Certified Professional Agronomist, invented what is called the compost filter sock. The process at that time involved using a blower truck or an auger to fill a mesh tube with composted media. The product immediately became a superior alternative to silt fence and continues today to replace silt fence in applications requiring reliable, consistent performance in stormwater management and erosion & sediment control applications. Also commonly known as filter sock, filter tube, mulch log, compost sock or log, the Filtrexx® Soxx™ technology was born.

Filtrexx History


Filtrexx began conducting research to test the performance limits of its products in a number of other stormwater and erosion control applications. Under the brand name SiltSoxx™, Filtrexx started targeting construction runoff and sediment control applications. Other applications quickly emerged to protect inlets, ditches, area drains, stream banks, steep slopes, mechanically stabilized earth (MSE) walls, channels, and even growing applications in agricultural settings. Over the next 10 years, Filtrexx continued to expand its product portfolio and improve manufacturing processes. Filtrexx has pioneered more than 100 applications using mesh, media and technical expertise to achieve desired results. Developing more than 100 types of Filtrexx Mesh and customizing different types of Media, transformed Filtrexx into the leading manufacturer of sustainable technologies for stormwater management, erosion and sediment control applications.


Filtrexx acquired The Living Wall Company™, a successful living wall brand based in St. Louis, Missouri. This new acquisition brought extraordinary synergies and expanded potential applications for existing GroSoxx® and GreenLoxx® product lines, specializing in living walls, retaining living walls, green roofs and bank stabilization systems.

Filtrexx acquired Weaver Express Erosion Control Solutions, a long-standing leader in erosion and sediment control services with presence in Ohio, West Virginia, Pennsylvania and New Jersey. Founded in 2001, Weaver Express became the largest Filtrexx partner in North America and after the acquisition it operated as Filtrexx® Northeast Division and currently operates as Filtrexx® Installation Services.

The impact Filtrexx had on stormwater management, erosion & sediment control, pollutant removal and living walls in a decade, gradually became noticeable across industries. Conwed Plastics, the leading plastic netting manufacturer in the world, and an important player in the erosion control industry, acquired Filtrexx to create synergies in both businesses. Conwed Plastics manufactures netting solutions for Rolled Erosion Control Products (RECPs), including Erosion Control Blankets (ECBs), Turf Reinforcement Mats (TRMs) and Sediment Retention Fiber Rolls (SRFRs). Filtrexx operates as a subsidiary of Conwed Plastics.


Filtrexx celebrates 15 years developing innovative and sustainable technologies for diverse stormwater management, erosion and sediment control, pollutant removal and living walls applications. Our Soxx technology continues to lead the field and we look forward to developing new sustainable solutions for all the industries we serve.


In January 2017, Schweitzer-Mauduit International, Inc. - SWM, acquired Conwed Plastics and its subsidiary Filtrexx International, to join the Advanced Materials and Structures Division (AMS). SWM is a leading global provider of highly engineered solutions and advanced materials for a variety of industries. Historically, SWM primarily served the tobacco industry, which remains a key focus. SWM also manufactures specialty papers for other applications and is executing a strategic transformation to diversify its product portfolio.

SWM's Advanced Materials & Structures segment, which focuses on resin-based rolled goods, includes DelStar Technologies, acquired in 2013, Argotec, acquired in late 2015, and Conwed Plastics acquired in 2017. These acquisitions expanded the Company's product portfolio and end segments served to include filtration, surface protection, medical and diverse industrial segments.

SWM and its subsidiaries conduct business in over 90 countries and employ approximately 3,100 people worldwide, with operations in the United States, United Kingdom, Canada, France, Belgium, Luxembourg, Russia, Brazil, Poland and China, including two joint ventures.
