PVC Tank Liners: Reliable Protection for Water Storage

What are PVC Tank Liners?
PVC tank liners offer a cost-effective and long-lasting way to protect storage tanks from internal corrosion, leaks, and structural wear. At Raven American Tanks, we supply and install high-quality PVC membranes engineered for durability, flexibility, and consistent performance across a wide range of tank types.
Whether your facility requires PVC membranes for clean water, industrial containment, or specialised storage, you can also review our full range of tank liner services in the main service section for broader context.
Why PVC Tank Liners are an Ideal Choice
Key advantages of PVC tank liners include:
- Excellent resistance to corrosion and moisture
- Strong protection against scratches and abrasion
- Compatibility with steel, concrete, wood, and poly tanks
- Flexibility for complex tank shapes and configurations
- UV-resistant construction for long-term outdoor use
- Lightweight, easy to transport, and quick to install
- Suitable for potable water, wastewater, fertilisers, and chemical solutions
- Long service life with minimal maintenance
PVC membranes deliver dependable protection for both new tanks and older systems in need of internal reinforcement.
Types of PVC Tank Liners We Supply
Our PVC tank liners are available in several specialised grades to suit different storage requirements and operating environments:
Potable-grade PVC liners
Certified for drinking water storage and safe long-term contact with potable water.
Industrial PVC liners
Designed for chemical resistance, wastewater containment, and high-demand industrial conditions.
Reinforced PVC membranes
Engineered with additional strength layers for tanks that experience heavy use or frequent pressure changes.
Flexible drop-in PVC liners
Ideal for fast installation, allowing tanks to return to service with minimal downtime.
Custom-formed PVC liners
Fabricated to match irregular, sloped, or oversized tank designs for a perfect fit.
These PVC liner types ensure reliable waterproofing, extended tank lifespan, and consistent protection across a wide range of water and industrial storage applications.
How PVC Lining Extends Tank Lifespan
Our PVC tank liners are fabricated to the exact dimensions of your tank to ensure a seamless fit. These liners are designed to securely cover floors, walls, joints, and panel seams, reinforcing the entire internal surface.
PVC liners are suitable for:
- commercial water storage systems
- irrigation and agricultural tanks
- industrial and chemical containment
- wastewater and greywater systems
- underground storage vaults
- tanks with irregular or custom shapes
PVC membranes are also commonly used as part of larger containment systems in pits, vaults, or hidden cavity tanks where additional waterproofing is required.

Drop-In PVC Liners for Efficient Installation
Raven American Tanks manufactures drop-in PVC liners for concrete, panel, and poly tanks. Each membrane is seam-welded to ensure strength, flexibility, and long-lasting performance.
Benefits of drop-in installation
- Quick placement with minimal tank downtime
- Immediate conformity to tank contours
- Secure adhesion to internal surfaces
- Reduced installation costs compared to structural upgrades
- Fast return-to-service for operational sites
Most installations are completed within one day, helping facilities resume normal operations without extended interruptions.
Where PVC Tank Liners can be Installed
PVC membranes act as a protective barrier between stored contents and the tank shell. This prevents moisture and chemicals from contacting internal surfaces, reducing rust, erosion, and structural degradation.
Unlined or poorly maintained tanks often develop:
- slow leaks
- internal corrosion
- contamination issues
- structural failures over time
If a PVC liner shows early signs of wear or surface deterioration, additional guidance is available in our tank liner repair and restoration section.
Manufactured for Strength and Precision
Our PVC liners are fabricated using high-quality coated materials and advanced seam welding methods. This ensures:
- optimal fit inside the tank
- consistent thickness and flexibility
- strong seam strength
- reliable performance throughout the liner’s service life
Made from locally sourced PVC compounds, our liners are designed to withstand demanding environments for up to 10 years, with straightforward repair options when needed.
Industries That Use PVC Tank Liners
Our PVC lining systems are used across:
- commercial and industrial facilities
- manufacturing and processing plants
- agricultural operations
- municipal and public infrastructure
- sports and recreation sites
- fire water storage and utility systems
Whether you need a new PVC liner or replacement for an aging membrane, Raven American Tanks provides tailored solutions for safe, long-lasting storage performance.
FAQ
How long does a PVC tank liner last?
A properly installed PVC liner typically lasts 10 years or more, depending on conditions and maintenance. UV-resistant and industrial-grade options can last even longer in demanding environments.
Is a PVC liner safe for storing drinking water?
Yes, PVC liners can be used for potable water when made with NSF-61 certified, phthalate-free materials. They help prevent contamination and maintain water quality across residential, municipal, and agricultural systems.
Can I use a PVC liner in an underground water tank?
Absolutely. PVC liners perform well in underground tanks and pits, protecting against soil moisture, corrosion, and structural movement. Their flexibility ensures a secure fit even on uneven surfaces.
What makes PVC tank liners a cost-effective solution?
PVC liners are affordable to manufacture, easy to install, and offer long service life. They help prevent leaks, reduce maintenance needs, and delay costly tank replacements.
