Raven CLI will be exhibiting at the Swanapalooza Show


Raven CLI will be exhibiting at booth #615, at the Swanapalooza Show — March 5-7, 2018.

If you are attending the show, be sure to stop by the Raven CLI booth (#615) and check out the latest innovations in geosynthetics for effective landfill and solid waste containment.  We will be featuring several targeted geomembranes including rugged Dura♦Skrim® N-Series reinforced geomembranes for temporary and long-term landfill covers, and advanced EVOH Absolute Barrier® for hazardous containment, along with popular HydraFlex™ flexible covers solutions.  Raven geomembranes are engineered to meet GRI Standard Specifications and NSF-61 certifications and are designed to reduce and eliminate odors, maximize capacity, and maintain groundwater, as well as to help landfills comply with government, state and local regulations.  For secure solid waste containment and landfill liner solutions, Raven CLI is a vertically integrated full-service solutions provider of products, fabrication and install techniques that facilitate high performance installations.

Raven is an experienced manufacturer of advanced multi-layer geomembranes for effective containment of liquids, solids, odors and hazardous gasses. We produce large prefabricated one-piece panels up to 8,000 lbs (4 acres in size depending on mil thickness) along with wide 24’ master rolls to be further fabricated onsite.  Prefabricated factory quality panels save substantial time and money, by reducing the number of seams and install days on site.  Savings up to 80% can be realized by utilizing large prefabricated factory panels and eliminating the time and testing required to install individual geomembrane sheet. 

A secure landfill is carefully engineered to avoid any hydraulic connection between the wastes and the surrounding environment. Geosynthetic components (cell liner, leachate collection ponds and landfill caps) represent a small fraction of the overall project cost, but virtually 100% of the protection.

We are looking forward to the show, and hope you will take the time to stop by and visit with our knowledgeable geo staff to see what we can do to maximize the value for your next project.  Also, be sure to sign up for our DeWalt® Jobsite Radio give-away at the booth, the winner will be drawn the last day of the show!

DURA♦SKRIM® N-Series are flexible reinforced polyethylene and polypropylene geomembranes uniquely designed to provide unmatched performance and durability for your most challenging projects.  Rugged N-Series products are reinforced with a closely knit 9x9 polyester 1000 denier scrim for exceptional toughness, and high tensile and puncture strengths.  A highly stabilized formulation consisting of antioxidants, UV stabilizers and carbon black provide excellent protection for long-term exposed applications.  

                • Heavy-duty scrim reinforcement grid

                • Exceptional dimensional stability

                • Large one-piece custom liners up to 8,000 lbs

                • Outstanding tear resistance and seam strength

                • Easily outperforms thicker non-reinforced membranes

DURA♦SKRIM® N-Series (30-45 mil) meets the GRI-GM standard specifications as outlined by the Geo Institute and are certified under the NSP/ANSI Standard 61, Drinking Water System Components – Health Effects.  Specific to coal ash containment—Raven manufactures stabilized DURA♦SKRIM® R-Series 8 mil reinforced temporary covers to 20 mil longer-term covers. 

ABSOLUTE BARRIER® geomembrane liners and covers provide superior containment performance to sustain and protect natural resources.  Absolute Barrier® is designed with an EVOH or nylon barrier layer to permanently block odor emissions, and hazardous contaminants in solid, liquid, and gas form including methane, gasoline, benzene, and a wide multitude of other harmful VOCs.  Available in 30 to 60 mil thickness with a smooth or textured surface.  

                • Advanced Odor Control - Up to 300x Less Permeable to VOCs

                • Effective Hazardous VOCs Containment

                • Large One-Piece Panels Reduce Install Time and Labor 

                • Proven EPS Geofoam Protection Results


HYDRAFLEX™ is a highly flexible geomembrane product line, designed to provide effective containment solutions for the environmental sector. HydraFlex™ Containment Solutions includes several targeted geomembranes designed for specific project attributes. All HydraFlex™ products are available in master rolls or large prefabricated panels, manufactured in a factory-controlled environment up to 8,000 lbs. per roll depending on mil thickness. The HydraFlex™ Series has a wide sealing-window for ease of field installation.  Highly-flexible HydraFlex™ Ultra LLDPE liners are recommended for use with coal ash as primary containment over compacted clay liners.
