Geomembrane Systems

For more than 35 years, BTL™ Liners has focused on providing best-in-class geomembrane systems and specialty geosynthetics for our customers. Geomembrane systems serve a variety of industries with the same end goal in mind – containment. We’ve been purveying geomembrane systems since the development of heavyweight reinforced polyethylene (RPE) liner products hit the scene in the 1980s.

BTL has sales volumes approaching 75,000,000 square feet annually. Our state-of-the-art facility in Prineville, Oregon, allows us to create the largest panels in the industry, in excess of 150,000 square feet. What we discovered long ago is that high-strength RPE and reinforced polypropylene (RPP) liners, tarps and covers could be prefabricated at our facility and installed quickly and cost efficiently. Imagine being able to complete your containment project with half the manpower, in less time with few liabilities. It’s possible with BTL Liners’ geomembrane systems.

Not only did BTLliners have the most competitive price for our liners, but also all your employees we had contact with made our experience enjoyable. I had 13 people to help unravel the liner. Men from all different trades including business owners and contractors. Every one of them were very impressed with Nick’s Jacobsen knowledge and demeanor. He took command but yet showed respect for the whole crew.

I want you to know how impressed I am with you and your product, from our very first conversation to the installation of the lining on our #12 hole. I was amazed at how quickly you were able to ship the product once you receive our lake dimensions, and how quickly the liner was seamed together. I highly recommend BTL to anyone who is considering installing a lake liner.

Ross J O’Fee, CGCS Golf Course Superintendent THE COUNTRY CLUB | SALT LAKE CITY, UTAH


We would like to thank you for all your effort and cooperation in arranging for the installation of the lake liners that your company has supplied for our golf course project here in Kuwait. I shall be more than pleased to recommend at any time your company here in Kuwait for any future projects that may arise either on the government level or in private sector.



Our pond leaked and was empty, creating an eyesore. So, the solution was to find a liner that could withstand the trauma of limestone rock substrate, but still be able to be installed by homeowners. I appreciated your putting up with several phone calls, and unparalleled packaging. We feel very fortunate to have done business with such a fine company, and fine regional office.



We found Jim Nicholson to be exceedingly knowledgeable about the liner products and everything associated with the construction of our pond. He was kind enough to visit us in Ohio and discuss the matter with our excavator before the project ever began. He truly went beyond the call to save us transportation costs just prior to the Labor Day weekend so we could stick to our plan.

Mark & Annette Saylor   MARK SAYLOR | OSTRANDER, OHIO


I just wanted to thank you for your wonderful service, excellent product, quick delivery and great price on the liner. After ordering online (and getting a little help from your sales staff) the liner was delivered in a few days. It hasn’t leaked a drop, looks great and blends in well with the surroundings. You have a great company with an outstanding product. Keep up the good work!

Jared, I wanted to send a “Thank You” for the liner installation that Travis Wilcox directed for us at Ft. Buchanan in Puerto Rico. Travis was very professional in both his knowledge and conduct and the liner was on the ground without any difficulty. In fact, it went much faster and with less pain than I had anticipated. I look forward to working with yourself, Travis, & BTL in the future.

John Baute Golf Project Superintendent.  CGCS Frontier


After our experience with both you and your professional staff, I find myself struggling to find the appropriate words to describe our wonderful relationship with your company. This was our third attempt at a pond installation at our home, and after spending a large sum of money with so called “pond experts,” BTL Liners was very highly recommended by our new pond engineer.



After speaking with you and your staff, I came away with a very good feeling. I suddenly felt enough bravado to run your ideas and methodology by my wife, who agreed, and together we turned the project over to your highly qualified staff. Following the pond addition, our property has been showcased by real estate agents who believe our land value has nearly doubled. We are beyond pleased with BTL Liners.



We were extremely impressed with the ability and professionalism of your team, where they not only successfully completed the job, but did so thoroughly and did not leave until the project was finished. We appreciate you working us into your schedule on such short notice and for sending top notch professionals. BTL will have all our liner business in the Inland Northwest moving forward.
