Reflectivity is engineering

Mirage is a high-albedo geomembrane engineered to bounce solar heat back into the sky, where Hypalon and other legacy black CSPE membranes absorb it. Less heat. Less evaporation. A longer service life for your containment or floating cover.

Same containment job, different physics

Hypalon absorbs heat. Mirage reflects it.

A dark, Hypalon-type surface heats up in direct sun — driving evaporation and long-term UV stress. Mirage’s engineered high-albedo surface reflects solar radiation the way a glacier does.

Why reflectivity matters

Hypalon and other CSPE membranes were engineered decades ago, when a dark, heat-absorbing surface was simply what a containment liner looked like. That choice has a cost: dark surfaces run hotter in direct sun, and heat drives evaporation, accelerates surface oxidation, and adds stress to seams over the life of a cover.

Mirage starts from a different premise. Available in Cool Tan and White, its titanium-dioxide-pigmented surface reflects solar radiation the way a glacier does — keeping the water, and the membrane itself, running cooler for the life of the installation.

The result shows up everywhere it matters on a spec sheet: reflectivity, weathering resistance, chlorine resistance, and flexibility — not just color.

Four reasons engineers are switching from Hypalon

Mirage: The Better Alternative to Hypalon. Here's What Actually Changes.

Full ASTM test data — every method, every result, by 45-mil and 60-mil thickness — is in the Technical Reference Guide. But here are the most major benefits of using Mirage as a better alternative to Hypalon.

01 — Reflectivity

Glacier-grade albedo

>80% TSR

Infrared-reflective titanium dioxide pigments bounce solar radiation back into the atmosphere instead of absorbing it — reducing evaporation and heat buildup under floating covers.

02 — wEATHERING

Built for accelerated aging

10,000+ hrs

A proprietary UV stabilizer and antioxidant package holds up through 10,000+ hours of Xenon-arc exposure — resisting the chalking and embrittlement that shortens the life of Hypalon surfaces.

03 — Flexibility

Handles the real install

20,000 cycles

Independently flex-tested to ASTM D6182 with zero damage through thousands of repeated fold cycles — so field seams and panel work hold up long after installation.

04 — Chlorine resistance

Built for treated water

>80% retained

Tested for extended exposure to 10–200 ppm chlorinated water (GRI-GM34), with no cracking observed and strong tensile strength retention — critical for potable reservoirs and treatment basins.

Independently verified

Not just a claim on a data sheet.

Mirage’s performance is tested against the same GRI GM34 benchmark used across the geosynthetics industry, and it carries NSF/ANSI/CAN 61 certification for potable water contact.

Where it goes to work

Built for containment that has to perform in the sun.

Hypalon’s dark surface was never built for constant sun exposure — it’s exactly where reservoir covers, potable basins, and open-air lagoons put the most stress on a membrane. Mirage is engineered for those conditions specifically.

Floating Covers

Reservoir and lagoon covers where reflectivity directly cuts evaporation.

vs. Hypalon: lower surface temps, less evaporative loss

Potable water

NSF/ANSI/CAN 61 certified for direct contact with drinking-water systems.

vs. Hypalon: certified chlorine resistance at 10–200 ppm

Secondary containment

Chemical and process-water containment with long-term seam integrity.

Wastewater

Lagoon and basin lining built to hold up under chlorinated and treated flows.

Fish hatcheries

Cooler water temperatures and a smooth, cleanable liner surface.
