LEADING MANUFACTURER Raven Engineered Films is capable of processing a broad range of materials, however our focus for many decades has centered on polyethylene, flexible polypropylene, EVOH and Nylon based geomembranes. We are the leader in reinforced polyethylene (RPE) and flexible reinforced polypropylene (fPPR) geomembranes with over 60 years of manufacturing expertise. These membranes have become the choice of specifiers due to their exceptional performance including chemical resistance, superior physical characteristics, longevity, high seam strength, and ease of installation along...

Raven specializes in producing reliable custom prefabricated drop-in panels up to 8,000 lbs (up to 4 acres) to optimize site coverage and significantly decrease install time and labor in the field. FABRICATED GEOMEMBRANES Quality built prefabricated panels save considerable time on site by significantly decreasing the number of weather exposed installation days resulting in reduced project costs. With proper planning and custom designed panel layouts, over 80 percent of field seaming can be eliminated and replaced with a higher quality factory certified seam produced in a controlled...

Pond and general containment liner requirements are extremely broad depending upon the liquid contents, longevity expectations, soil conditions, geographical location, and many other factors. A thorough geomembrane selection that matches the containment requirements, in conjunction with proper construction methods and design, will result in a long-term reliable containment system. Raven manufactures a wide-range of geomembrane liners to meet your individual containment requirements. You can choose from durable unsupported HydraFlex™ LLDPE geomembranes ranging from 20 mil to 40 mil in...

Raven's exclusive GeoGrip™ textured surface is also an option, consisting of durable random spikes and bidirectional bars for applications requiring an anti-skid surface. Raven Absolute Barrier® XB-Series 60 mil, is an HDPE geomembrane designed with an inner core of highly effective EVOH or Nylon gas barrier resin to provide a solution for floating covers requiring exceptional chemical resistance to oils, greases, VOCs, and challenging odors. Uses for Absolute Barrier® include waste ponds, sewage ponds, dairy waste and anaerobic applications. Raven floating cover materials are available in...

This is where a true gas barrier to VOC pollutants such as gasoline, diesel, dry cleaning fluids, solvents and other toxic materials is vital when choosing an under concrete slab gas barrier to minimize gas and vapor intrusion into a building or other enclosed structure. Depending upon specific site conditions, gas barriers can also be designed to protect open areas, including redeveloped city parks or golf courses and other recreational areas. Raven manufactures VaporBlock® Plus™ and a full line of Absolute Barrier® products designed to be placed directly below concrete slabs. VaporBlock®...

Raven offers the same odor/gas barrier technology in an interim landfill cover solution with a 20 mil scrim-reinforced material. Dura ♦Skrim® RB-Series incorporates high-strength reinforcement with an advanced gas barrier designed to provide an effective barrier to landfill odors and gases. The RB-Series is manufactured with an outer ply consisting of seven-layers including high performance polymers with an integrated core of chemically resistant EVOH or Nylon barrier resins. This limits migration of volatile organic compounds including methane, halogenated hydrocarbons, aromatic...

On October 19,2015, Disposal of Coal Combustion Residuals from Electric Utilities final ruling became effective. It provides safeguards for the proper handling, storage, and impoundments of coal combustion residuals (CCRs). This regulation is geared to protect drinking water from hazardous contamination, prevent air emissions of coal ash dust into the environment, and foremost, to help protect communities from catastrophic failures of coal ash surface impoundments. The rule was promulgated under subtitle D (non-hazardous solid waste) of the Resource Conservation and Recovery Act. The new...

Raven's unique product line-up includes geomembranes designed to provide effective containment of liquids, solids, odors and hazardous gasses. This is achieved with our multi-layer gas barrier technology, ability to introduce tough reinforcements and precision textures, unlike others in the industry. In the environmental sector, Raven geomembrane liners and covers protect our surroundings through proven containment solutions. Absolute Barrier® Y-Series - LLDPE 7-Layer Barrier Y-Series (30-40 mil)—Seven-layer co-extruded geomembranes consisting of very flexible, linear-low-density...
