PondEasy vs PondGard: Which Elevate EPDM Pond Liner is Right for Your Build?
Once you've decided on EPDM as the right liner material, the next decision is which Elevate™ grade to buy. The range splits into two clear products, PondEasy™ (0.80mm, 10-year warranty) and PondGard™ (1.14mm, 25-year warranty). Both grades are rated for rockwork, the choice between them comes down to warranty length, thickness, and the heavier-duty applications PondGard covers.
This guide compares them side by side, walks through real-world build scenarios, and tells you exactly which one to choose for your project.
The Short Answer
For small decorative ponds, mini ponds, and patio water features, PondEasy 0.80mm is the cost-effective choice and is rated for use under rockwork on these smaller builds. For ecosystem ponds, pondless waterfalls, koi ponds, recreation ponds, swim ponds, and any commercial water feature, PondGard 1.14mm is the spec with the longer 25-year warranty and the heavier-duty load tolerance.
Side-by-Side Comparison

PondEasy: The Entry-Level EPDM
PondEasy is the lighter, more affordable EPDM grade with a 10-year warranty. It's the same EPDM rubber compound as PondGard, still fish-safe, still UV-resistant, and rated for use under rockwork on smaller residential builds. The difference is in thickness and warranty length, which affect load tolerance for larger or higher-stress applications.
Choose PondEasy when:
- Your pond is under approximately 5,000 L
- You're building a mini pond, patio pond, or container water garden
- It's a bog filter or wetland edge feature
- It's a small DIY backyard build, including with decorative rockwork
- It's a DIY build where weight matters (one-person installs)
- Budget is a constraint and you're comfortable with the 10-year warranty for the scale of build
PondGard: The Professional Standard
PondGard 1.14mm is the heavy-duty spec with a 25-year warranty. It's the direct successor to Firestone PondGard, the membrane pond builders have been specifying for over forty years. It's the choice for any serious build where the longer warranty and higher load tolerance matter.
Choose PondGard when:
- You're building a standard ecosystem pond
- Building a pondless waterfall
- Building a residential or show-grade koi pond
- It's a recreation pond or natural swim pond
- The pond will see foot traffic
- It's a commercial water feature
- It's a dam, lake, or retention pond
- You want the longer 25-year warranty as part of the spec
Real-World Build Scenarios
Scenario 1: Patio Mini Pond
A 1.5 m x 1 m container-style mini pond on a Brisbane apartment patio. 400mm deep at the deepest. A few aquatic plants, decorative pebbles around the edge, lifestyle feature rather than a permanent landscape installation.
Recommendation: PondEasy 0.80mm. Liner size approximately 2.9 m x 2.4 m, fits on the 3 m roll. Easily handled by one person, lower cost, the 10-year warranty matches the kind of build that will likely change with the household over the same period.
Scenario 2: Backyard Ecosystem Pond
A 4 m x 3 m ecosystem pond in a Sunshine Coast backyard. 900mm deep. Substantial perimeter rockwork, planting shelves at three levels, a small waterfall, and goldfish. Owner wants this to be a permanent feature for the property.
Recommendation: PondGard 1.14mm. Liner size approximately 6.4 m x 5.4 m, cut from the 7.62 m roll for clean coverage. The longer 25-year warranty and heavier-duty load tolerance match the permanent-feature build intent.
Scenario 3: Pondless™ Waterfall
A 4 m long stream feature with a 0.6 m drop waterfall in a Perth backyard. No standing pond, water disappears into a hidden AquaBlox™ reservoir. Heavy rockwork along the stream channel.
Recommendation: PondGard 1.14mm. Pondless features see substantial rockwork and continuous water flow. The 1.14mm spec and 25-year warranty are the standard for waterfalls and streams.
Scenario 4: Recreation Pond / Natural Swim Pond
A 12 m x 8 m natural swim pond in a Melbourne property. 1.5 m deep in the swim zone. Stone-set perimeter, gravel beach entry on one side, dense rockwork around a circulation waterfall. People will swim in it. Major landscape investment.
Recommendation: PondGard 1.14mm. Foot traffic, scale, and build value all justify the spec. Liner size approximately 15 m x 11 m, likely joined on-site from two sheets from the 9 m or 12 m roll widths. The 25-year warranty backs a major landscape investment.
Scenario 5: Farm Dam Restoration
A 25 m x 15 m existing earth-walled dam in rural NSW that has lost its water-holding capacity. Owner wants to line it for stock water reliability. No rockwork, but the dam floor has irregular contours and tree-root remnants.
Recommendation: PondGard 1.14mm. Large scale, irregular substrate, and long-term commercial-style application. Full underlay is critical. Likely joined from multiple 15 m wide rolls. The 25-year warranty matters on a stock-water reliability build.
Cost Difference: What You Actually Pay
PondEasy starts at $77.55 per lineal metre cut to size. PondGard starts at $99.65 per lineal metre. The per-metre difference of around $22 stacks up on a large project but is a small fraction of total build cost for most residential ponds.
On a typical 4 m x 3 m ecosystem pond requiring approximately 6 m x 5 m of liner, the difference between PondEasy and PondGard is in the order of $130 to $200. Against a total pond build cost that often runs to several thousand dollars, and combined with the 25-year warranty versus 10-year warranty difference, PondGard is rarely the wrong choice on any serious build.
Joining and Accessories: The Same Across the Range
Both PondEasy and PondGard use the same joining system, QuickPrime Plus and QuickSeam Splice Tape. The same underlay options apply. The same installation method applies. So if you've worked with one grade before, the other is familiar.
The only thing we'd note is that joining different thicknesses to each other isn't recommended. Stick to one grade per pond, even when joining sheets.
Which Should You Order?
If you're building a small decorative pond or patio feature and the 10-year warranty fits the project, PondEasy is the right choice. It's lighter, easier to handle, and well-priced.
For anything else, default to PondGard 1.14mm. The 25-year warranty, heavier-duty spec, and broader roll-width range make it the safe choice for any project where you want the build to last and the warranty to back it.
Either way, order our free Pond Liner & Underlay Sample Pack first. It includes both grades so you can feel the weight and flexibility difference before committing to a roll.
Frequently Asked Questions
Is PondEasy the same material as PondGard?
Yes. Same EPDM rubber compound, same fish-safe rating. The differences are thickness (0.80mm versus 1.14mm), warranty length (10 years versus 25 years), and the heavier-duty applications PondGard is rated for.
Can I use PondEasy under rocks?
Yes. PondEasy is rated for use under rockwork on smaller residential builds. For larger builds, recreation ponds, swim ponds, or commercial water features, step up to PondGard 1.14mm.
What's the difference between PondEasy and PondGard?
PondEasy is the 0.80mm entry-level grade with a 10-year warranty, suited to smaller decorative ponds, mini ponds, and bog filters. PondGard is the 1.14mm professional grade with a 25-year warranty, suited to ecosystem ponds, koi ponds, recreation ponds, swim ponds, and commercial water features.
Is PondGard worth the extra cost over PondEasy?
For any build where you want the longer 25-year warranty and the heavier-duty spec, yes. The marginal cost is small relative to total build cost and the warranty difference is significant.
Can I join PondEasy to PondGard?
Not recommended. Different thicknesses have different expansion characteristics and the seam becomes a weak point. Stick to one grade per pond.
Which grade do Certified Aquascape Contractors use?
Almost all CAC builds specify PondGard for the 25-year warranty and heavier-duty spec. PondEasy is used on smaller decorative builds where the 10-year warranty matches the project scope.
What roll widths is PondGard available in?
PondGard 1.14mm is available in 3 m, 4.5 m, 6 m, 7.62 m, 9 m, 12 m, and 15 m roll widths, cut to size or as full rolls.
