How to Decide When to Use RPE vs RPP Liners

At BTL Liners, we proudly fabricate liners, tarps and covers from both reinforced polyethylene (RPE) and reinforced polypropylene materials. We’ve fabricated and installed nearly one billion square feet of RPE liners, making us one of the most trusted and relied upon manufacturers in the industry. We’re often asked what situations call for the use of RPE liners and when to use RPP liners. This week, we discuss the differences between the two liner materials and when you should use each.

The Difference Between RPE and RPP Liners

The main difference between RPE and RPP liners comes in how they are made. RPE liners are coated in liquid plastic, while RPP liners are coated and pressed. Because RPP liners are pressed, it allows the coating to go into and through the scrim, which is better for surface welding and won’t peel off. RPP liners have a thicker coating than RPE liners.

Applications for RPP Liners

RPP liners are great for above ground containment, from drop-in liners to floating covers. RPP liners work well inside tanks. Additionally, RPP liners are recommended for low levels of byproducts and low chemical mixtures. With their high level of chemical, UV and weather resistance, RPP liners work well for secondary containment, at wastewater treatment plants and for floating covers and drop-in tank liners.

Applications for RPE Liners

RPE liners are most commonly used for water containment. Due to its unmatched puncture and tear resistance, RPE shines as one of the best liner materials for water containment. When RPE is manufactured, only virgin resins are used. An LLDPE coating is applied to add UV and abrasion resistance. This also makes it highly impermeable and gives it enhanced welding properties. RPE liners are best for use in ponds, irrigation canals, reservoirs and for short-term soil remediation.

RPP and RPE liners both have many benefits and can be used in a variety of applications. RPE liners tend to be better for water containment, while RPP works well for floating covers and secondary containment.

  1. I would like to get a quote for a 30 mil RPE membrane. The liner size is calculated to be 284’x159’ or 45,156 SF. The liner will be fully buried with +/- 3’ of dirt , except at the waterline which will be +/- 1’. I’m still looking at my timing but looking at doing it before mid December. I will need it delivered to Sullivan Mo 63080.
    Please let me know once the order is placed, your timing on manufacturing and then delivery? Let me know how it will be shipped given that it is one piece?
    Can you forward any technical data on your product AND A SAMPLE?
    Will I need to install a sub-liner, if so what is that cost?
    Can you forward any details on your recommendations on key’ing it into the bank or other means of attachment?
    What is your recommendation of going around posts? I have 4 dock legs that I will need to flash around.
    Given the size, what would you guess on how long to install if the hole is dug and the trench around the perimeter is already dug? How big of crew do you suggest?

    Look forward to your reply.

  2. Greg,
    Thank you for your inquiry! This would ship as one panel. 284’x159′ $22,126.44. We would need to ship on a flat deck as the weight exceeds what regular LTL service provides. You would need to have some sort of equipment to get the liner off the truck. Once the order is placed and paid in full, it would ship within 4 days and shipping time would be another 4 days. We have boot kits for going around the posts of your dock and would be great to call and speak with Travis or Nick, regarding installation of both the liner and the boots.. 541-447-0712/ 800-280-0712

    Thank you!

  3. Hello,
    I am installing a koi pond in my yard that measures 11’L x 6’W x 2.5’D. What mil thickness RPE liner would you recommend and total cost? Can my wife and I handle the installation?

  4. Tony,
    Thank you for the inquiry! The average liner for this application is the BTL-30 which is $0.49 per SF. I believe you and your wife would be fully capable of installing the liner! We would need to know the ship to Zip code to get your shipping cost for this liner. Please feel free to call us 541-447-0712 for more info regarding your project! I will also reach out by email!

    Thank you,
