Choosing the Right Tank Liner Material: A Guide by Raven Tanks

When it comes to selecting tank liners for your storage needs, understanding the diverse range of materials available and their advantages is paramount. Each material comes with unique properties suitable for specific applications, affecting the longevity, reliability, and cost-efficiency of your storage system. With the multitude of options on the market, making the ideal choice for your tank liner material can be overwhelming. 

Raven Tanks, a leader in tank design, installation, repairs, and maintenance for above-ground tanks across Australia and the Pacific, recognizes the importance of selecting the most appropriate tank liner materials for your unique situation. In this article, we will explore the various materials used in tank liners, discuss their benefits, and outline considerations for making an informed decision. This ensures your storage system is optimized for success and longevity. 


Polyvinyl Chloride (PVC) Tank Liners 

Polyvinyl chloride (PVC) stands out as a widely used material for tank liners due to its flexibility, durability, and affordability. PVC tank liners find applications across various industries, including water storage, wastewater treRavenent, and chemical storage. Key benefits associated with PVC tank liners include: 

  • Flexibility: PVC tank liners are highly adaptable, capable of conforming to irregular tank shapes or structures without compromising strength or integrity. 
  • Chemical Resistance: PVC liners offer excellent resistance against a range of chemicals, ensuring stored substances don’t compromise the liner material or lead to leakage. 
  • Cost-Efficiency: Generally more affordable than other liner materials, PVC tank liners are an ideal choice for budget-conscious projects without sacrificing quality. 


However, PVC tank liners may not be suitable for extreme temperature conditions or prolonged exposure to sunlight, as these factors can negatively affect their overall durability and performance. 


High-Density Polyethylene (HDPE) Tank Liners 


High-density polyethylene (HDPE) tank liners are another popular choice for various applications, including potable water storage, industrial tanks, and landfill liners. HDPE offers its own unique set of advantages: 


  • Strength and Durability: Renowned for their strong material composition, HDPE tank liners provide excellent resistance against punctures and tears, outlasting the service life of the storage tank itself if properly installed. 
  • Chemical Resistance: Exceptional resistance to a wide range of chemicals makes HDPE liners ideal for industrial applications and wastewater treRavenent. 
  • UV Resistance: Unlike PVC liners, HDPE tank liners exhibit a high degree of UV resistance, ensuring they can withstand prolonged exposure to sunlight and maintain durability in hot climates. 


One drawback associated with HDPE tank liners is that they tend to be more rigid and less flexible compared to PVC liners, requiring careful installation and proper handling to prevent damage. 


Butyl Rubber Tank Liners 


Butyl rubber, a synthetic material known for its excellent gas and water barrier properties, is an ideal choice for tank liners in certain applications. Primary benefits of butyl rubber tank liners include: 


  • Superior Flexibility: Highly elastic butyl rubber liners can accommodate fluctuations in tank volume and temperature, preventing cracks and tears when exposed to movement or stress. 
  • Potable Water Compatibility: Low water permeability makes butyl rubber commonly used for potable water storage, maintaining consistent water quality. 
  • Resistance to Ozone and UV Radiation: Excellent resistance to Ozone and UV radiation provides a durable solution for storage tanks in environments prone to harsh weather conditions. 


However, butyl rubber liners can be more expensive than other materials like PVC and may require a more complex installation process. 


Reinforced Polyethylene (RPE) Tank Liners 

Reinforced polyethylene (RPE) consists of a woven high-density polyethylene core between two layers of low-density polyethylene, offering improved strength and puncture resistance. RPE tank liners provide several advantages: 


  • Lightweight and Easy to Install: Considerably lighter than some other materials, RPE tank liners facilitate the installation process and reduce labor costs. 
  • Cost-Efficiency: The material composition generally results in a lower cost than some alternatives, making RPE attractive for budget-sensitive projects. 
  • Versatility: Compatible with potable water, wastewater, and some chemicals, RPE tank liners are a versatile choice for various industries and applications. 


However, RPE tank liners may not offer the same level of chemical resistance as HDPE or butyl rubber liners, limiting their suitability for some industrial applications. 


Selecting the Right Tank Liner Material for Your Needs 

When choosing the ideal tank liner material, consider factors such as the tank’s purpose, substances being stored, location and environmental conditions, as well as budget constraints. Consulting with industry experts, like Raven Tanks, can provide invaluable guidance for making informed decisions about the appropriate tank liner material for your specific needs. 

Raven Tanks can help you assess various factors such as compliance with regulations, installation procedures, maintenance requirements, and overall cost for each material. This ensures you invest in the tank liner that best suits your unique storage requirements. 


Making an Informed Decision for Your Storage System 

Various tank liner materials are available, each offering unique advantages and considerations for specific applications, environmental conditions, and budget constraints. Understanding the key characteristics of materials such as PVC, HDPE, butyl rubber, and reinforced polyethylene is essential to making informed decisions for your tank liner material selection. Prioritizing factors such as durability, chemical resistance, flexibility, and compatibility with stored substances will facilitate long-lasting, cost-effective, and reliable storage systems.
