Starting as a plastic manufacturing company in 2002, KEENE has continually innovated new construction tools in an effort to improve product performance for the market. At first, KEENE only manufactured entangled net products in applications that had coatings and concrete all around them. Today, our diverse capabilities include blending powders and creating chemicals. In addition to our expertise in plastics extrusion we’ve expanded our expertise to floor preparation products, below grade systems, roofing, plastic fabricating and 3D filament.


The creative juices flow here and our highly educated, professional team is one of the best and brightest in the construction industry. Our company sits in a hotbed for start-ups and entrepreneurial atmosphere in Cleveland, Ohio. Northeastern Ohio is one of the most thriving plastics regions in the world with some of the best universities on polymer education within minutes of our research facilities. We think we represent this spirit as our business grows and we employ more people in all facets of our business. 


Since we launched in 2002, KEENE has acquired companies that began in the 1910’s, 1950’s, 2000's. That “grey hair” helped us create stability and manufacturing expertise, but we offer more. The platform we built can grow far into the future and sustain more customers and markets. People have thought of KEENE as merely a filament manufacturer, think of us as the innovation company for apartment noise control, building envelope, roofing and floor preparation.
