Premium Grade RPE Pond Liner
High quality RPE liner is extremely strong and lightweight, is fish and plant safe, and is available in very large panels!
This liner is also available in a 30 mil Laminated version. The laminated version has higher hydrostatic resistance, is more resistant to heavy creasing or folding in the case of above ground boxes or tanks, and is much more UV resistant for long term UV protection even if left uncovered.
Available in 3 thicknesses - the 30 mil is most popular and is our 'goto' thickness. The 24 mil is available for situations where budget concerns exist. The 40 mil is our extra-strength option and is much more puncture and tear resistant. The 40 mil liner is also a little stiffer to work with because of the added thickness.
Off the roll discount: there is a slight savings for 12' wide liners of any length.

Our Premium Grade RPE (reinforced polyethylene) pond liner features a high puncture and tear resistance - around 2 to 3 times stronger than EPDM, PVC and HDPE liners. As an added plus, RPE has a high UV resistance and won't degrade when exposed to chemicals such as fertilizer nitrates and hydrocarbons. One of the biggest advantages of our RPE liner is that many different sizes are available, and because of it's lighter weight, single panels up to approx. 60,000 square feet can be produced. With regards to weight,RPE is approximately 1/3 of the weight of Firestone's pond guard EPDM rubber liner. This weight difference makes it substantially easier to handle and install, especially in larger panels.
Why do we call it ‘Premium Grade’? Our RPE liners are 100% made in North America with only the best raw materials. As a result, Everything Ponds Premium Grade RPE liner is one of the first RPE liners in the industry to feature a NSF-61 rating! This is the highest rating a liner can receive, which makes it suitable for holding human drinking water as well as use in organic farming situations. It’s basically guaranteed that no harmful chemicals will leach out of the liner into the water like some other cheaper RPE liners made in either India or China. Looking for only the best for your fish, plants? Then this liner is for you.
RPE is a little less "bendable" than EPDM rubber, but it is still more than flexible enough to bend around corners, bends and shelves in a pond. For a visual comparison between RPE and EPDM rubber, please watch the below video. Even though RPE is a little less flexible than EPDM, it's around 3 x stronger, which really helps create a more reliable liner installation that is less likely to tear or puncture.
Which Thickness is Best?
The 30 mil liner is our most popular liner option for most ponds. It gives a good mix of strength, and ease of installation. For small to medium sized outdoor ponds that are placed in-ground with a large number of shelves, corners and bends, the 24 mil liner will provide some extra ‘bindability’ but you will sacrifice a little bit of strength to get it. As the liner strength increases, the stiffness of the liner also increases a little bit. As we said above, the 30 mil is our most popular liner - it’s a little stiffer than the 24 mil liner, but it’s quite a bit tougher and more difficult to damage or puncture. For applications where no leaks are paramount or for applications above ground, we would recommend at least the 30 mil. The 40 mil is even tougher than the 30 mil, but it also gets a little stiffer again because it goes from one layer of reinforcing in the 30 mil, to two layers of reinforcing in the 40 mil. The only time the stiffness of a liner really matters is if a pond has a number of shelves, corners, bends, and therefore a lot of folding and pleating is required. In these cases, a 24 mil or 30 mil is definitely easiest to work with, but that being said if you’re determined, you could get the 40 mil in there. For larger applications like large ponds, small lakes, golf course water hazards etc, the 30 and 40 mil options are our go-to liners - they’re much easier to install than a PVC or HDPE liner, and also provide much longer life!

Video: Which Thickness of RPE Should you Buy?
As long as our premium grade RPE liner is covered with water, or some kind of fill or protective layer, we guarantee a life of at least 20 years. If the liner is taken care of, you could easily see 20, 30 or even 40 years life. If the liner is directly exposed to the sun and is not covered with water, soil or another material, the liner should still last around 10 years before it succumbs to UV damage and needs to be replaced. If you need even more life when directly exposed to the sun, please have a look at our Premium Grade RPE liner for large ponds - the 40 mil extra strength liner has an expected life of 15 years when directly exposed to the sun.
Our EP-RPE liner is warranted to be free from defects in material and workmanship for 20 years from the day of purchase. This includes the ability of the liner to withstand normal weathering and environmental degradation when used as a primary containment membrane holding water. There are a few limitations however for the warranty to be valid: The liner must be covered at all times by soil or water, the warranty is not covered against damage resulting from acts of god, or catastrophic events such as earthquakes, tornadoes, or hurricanes. The liner is also not covered against punctures or damage resulting from improper installation, or use. Examples of improper installation or use include damage by machinery or other equipment, people, animals, ice, or sharp/rough objects in the soil or substrate.
Packaging and Installation
All our RPE liners are initially manufactured in long rolls that are 12’ wide (except for the 40 mi liner which is 10’ wide). To make a specific liner size, we then heat-weld 2 or more liner sheets together, creating high quality heat-welded seams in the liner. These heat welded seams are guaranteed not to leak and carry our full warranty like the rest of the liner. All Liners weighing less than 150 lb. are then packaged into a box and shipped via UPS ground, which takes between 3 to 6 business days depending on your location in the USA. Anything larger is shipped via freight truck on a pallet. The liner comes packaged in a roll. The first step to installation is to place the liner in one one corner of the pond so that you'll be unrolling the liner in the long direction of the pond. For example for a 60' x 30' pond, the long direction will be the 60' edge. After unrolling, the liner is now accordion stacked, which means you can grab the top edge of the liner and pull it across the width of the pond. For every 12' of liner, it helps to have one person helping to pull. So for a 48' long liner, you'd want to have at least 4 or 5 people to help pull the liner across the width. If you're dealing with a very large liner that is very heavy, such as a liner that is over 150', you may want to unroll the liner down the middle of the pond instead of the edge. This way, you have less material to pull across the width since you would only have to pull the liner across half the width at a time. We have installed liners up to 250' x 250' using this method.
Once the liner is loosely laid over the pond excavation, you can begin smoothing the liner down to get it lying as flat as possible. This may involve folding and pleating the liner here and there. Try to leave at least 1 to 2 feet around the entire edge so that you can anchor the liner down by either digging an anchor trench, or by covering with fill (see pictures below).
Covering the Liner
After the liner is laid down and conformed to the bottom of the pond, it a good idea to cover the liner to make the pond look more natural, as well as to help protect the liner from long term UV exposure. For a pond with vertical walls, we like to stack rock to make an underwater rock wall around the edge. The top of the wall can then extend slightly above the water level to provide a nice rim around the pond. If building a larger pond or lake where the bottom slowly slopes down towards the deepest area in the middle, then we typically like to lay down a strip of geotextile fabric around the entire perimeter of the pond. The fabric provides some grip and protection when putting down a fill layer next. The fill can be anything really - sand, clean gravel, nice rocks etc. The basic idea is to put down some fill to hide the liner and make the pond look more natural. If the slope of the pond is anything steeper than 6 to 1, then the geotextile is fairly important to keeping the fill material from sliding down the slippery liner.
There are actually a few ways to detail the edges of a large pond. Here are a few ideas we use commonly:

Frequently Asked Questions
What are the ADVANTAGES of a RPE (reinforced polyethylene) liner over EPDM rubber?
The main advantage is the strength and weight of the liner. RPE is considerably lighter than EPDM, and even though it's thinner, it is more puncture resistant. In some cases, if the RPE membrane is being placed on regular soil or sand, then no protective underlayment is needed.
What are the DISADVANTAGES of a RPE (reinforced polyethylene) liner over EPDM rubber?
Despite being lighter and stronger, RPE is a little less pliable than EPDM. This usually isn't that big of a deal though for most ponds since the RPE liner can still easily be folded and pleated.
When is a protective underlayment needed?
Because of it's high puncture resistance, the EP-RPE liner doesn't need a protective underlayment if being placed on clean soil or sand. In the event of laying the membrane against rock, gravel, or soil with rock, then a protective underlayment should be used to prevent a possible puncture. We recommend our high quality Pond Liner Underlayment.
Does the EP-RPE liner need to be covered with anything before the pond can be filled with water?
EP-RPE is a UV stable product. Below water level, it is not necessary to cover or bury the liner for extended performance. However, even though the liner is UV stable, we still recomend covering the liner above water level with something since even the most UV stable products can loose their flexibility over extended periods of times. Covering the liner above water level provides aesthetic benefits as well. By covering the liner with rocks, plants or other coverings, it helps to create a more natural looking landscape If putting soil or sand on top of the liner and the edges of the pond are sloped, it might be a good idea to place a geotextile fabric over top of the EP-RPE liner to prevent the sand/soil from sliding/slipping down the slope.
What maximum slope is allowed when covering the liner with sand/gravel/clay to prevent the material from sliding down the slope?
We recommend a maximum slope of 6 to 1 if there is no geotextile fabric over top of the liner. Anything steeper than that may result in the ballast material (sand, gravel, soil etc) sliding down the liner towards the middle of the pond. By adding a geotextile fabric over the liner, steeper slopes can be achieved.
Is some kind of ballast material necessary to hold the liner down and keep it from floating?
If you don't have any ground water or high water table at your property, then you don't need any ballast on top of the liner. The weight of the water will push down and hold the liner in place. However if you do have a high water table, it's a good idea to use something to anchor the liner to the bottom of the pond and prevent it from moving/floating. This can be achieved with sand, small gravel, or larger heavier objects strategically placed throughout the pond. You don't have to completely cover the liner, but a wheel barrow load of sand here and there would add a bit of weight if ground water came up under the liner.
What is the maximum size of ballast material allowed before a protective layer is required over top of the liner?
For ballast material, we typically say gravel less than 1" in size doesn't require a protective layer over top of the liner. The larger the aggregate size, the more likely it is to damage the liner when spreading out the material , so if using a 1" piece, spread the material out carefully. If using ballast over 1" in size that has sharp corners and edges (like crushed gravel), we recommend a protective geotextile fabric to help prevent damage to the liner.
What is the best way to install the liner?
The liner is generally accordion stacked, and then rolled into a roll for shipping. To install, first start by placing the roll at the corner of the pond, so that it will unroll in the long direction. For example, if your pond is 20' x 40', the long direction is the 40' edge. After rolled out along the long edge, grab the top edge of the liner and pull it straight across the width of the pond. Depending on the size of the liner, you may need a number of people to help pull.
