Recognizing Innovation in Geomembrane Advancement

Dow’s commitment to advancing geomembrane performance has earned global recognition. Our collaborative research with Layfield was named an R&D 100 finalist, highlighting the breakthrough potential of INTREPID™ Bimodal resins in geomembrane technology. Building on this achievement, Dow also presented a recent technical paper at the GeoAsia conference, reinforcing our leadership in developing materials that meet evolving standards like GM42 and deliver long-term containment reliability.

Enhancing Geonet Drainage Performance

Geonets play a critical role in drainage and filtration systems, often used alongside geomembranes to manage fluid flow and protect containment structures. Dow supports this essential function with unimodal and bimodal polyethylene resins that offer strength, dimensional stability, and chemical resistance. While our geonet solutions are in early-stage development, we’re actively evolving bimodal formulations to enhance stress crack resistance, processing efficiency and long-term performance—helping the industry transition toward more durable, sustainable drainage materials.
