Custom Water Tank Liners

Reef Industries is your trusted U.S. manufacturer of high-performance water tank liners manufactured to meet demanding storage and containment needs.

When water storage systems demand long-term durability and minimal risk of leaks, Reef Industries is here. For over 65 years, we’ve specialized in reinforced thermoplastic films that outperform standard liners in strength, customization, and reliability. Our Permalon® water tank liners are precision-engineered to provide lasting containment in agricultural, industrial, and municipal applications, where failure is not an option. Get in touch today!

Our Permalon® plastic water tank liners are constructed from a unique cross-laminated polyethylene that resists punctures, UV exposure, and chemical degradation. The result is a durable water tank liner that performs in some of the most challenging containment environments—indoors or out, hot or cold.

Each Permalon® liner is:

• Lightweight and easy to install
• Cold-crack tested for performance in freezing temps
• Factory-fabricated to reduce costly on-site seaming
• Available in FDA-compliant grades for potable water storage
• Custom-built for round, rectangular, or irregular tank geometries

From flexible water tank liners for livestock tanks to large water tank liners used in stormwater management, Reef Industries offers tailored protection backed by material science and manufacturing expertise.

Off-the-shelf liners often leave room for compromise. At Reef Industries, we engineer a true fit from the beginning. Every custom water tank liner is fabricated in-house at our Houston-based facility using CAD patterns, heat welding, and multi-point quality checks. This means fewer seams, faster installation, and a better-performing product for the long haul.

Add-on options include:

• Grommets, rope-in-hems, or reinforced edges for secure fastening
• Pipe boots, flange seals, and bulkhead fittings
• Velcro closures, zipper access points, or D-rings for service access
• Repair kits and liner tape for long-term maintenance

No matter your application, we work with your drawings, measurements, or even just an idea to fabricate a solution that fits your tank and your timeline.

Reef Industries’ industrial water tank liners are trusted across sectors where liner failure isn’t just a mess—it’s a major liability. Our products are routinely used in:

• Agricultural operations: For irrigation tanks, nutrient reservoirs, and livestock watering systems
• Industrial containment: Including process water, chemical-neutralization tanks, and rinse systems
• Municipal infrastructure: From emergency storage to potable water tanks and rainwater harvesting
• Aquaculture and aquaponics: Where water purity and liner flexibility are key

With customizable performance properties—including UV resistance, chemical tolerance, and food-safe formulations—Permalon® liners are engineered to do more, last longer, and reduce maintenance over time.

Reef Industries isn’t a reseller. We’re a U.S. manufacturer with full control over our materials, processes, and quality. That means you get:

• Direct access to experts who understand water containment
• In-house fabrication with short lead times
• Consistent material supply, even for large-scale projects
• A responsive partner that builds relationships, not just liners

When professionals across agriculture, industry, and municipal operations need water tank liners that stand up to pressure—literally and figuratively—they choose Reef Industries.
