The Benefits of PVC Tank Liners in Water Storage Tanks

Containment methods are critical in light of current government environmental regulations. Internal flexible PVC tank liners provide your large storage tank with cost-effective primary containment and corrosion protection.

A PVC tank liner is a strong lining material that is also flexible and resistant to chemicals. The liner is suspended inside the tank and acts as the primary containment for the stored material. Once in the tank, the material only comes into contact with the liner.

When secondary spill containment is required, PVC tank liners are an excellent choice. Secondary containment is a secondary barrier or outer wall that acts as a double enclosure to prevent hazardous substance leakage and contamination of water and soil. Furthermore, it strengthens storage systems by containing materials that are corrosive, combustible, reactive, flammable, or toxic.

When it comes to flexible pond liners, polyvinyl chloride (PVC) liners are the least expensive option.

They are not as heavy as EPDM liners and provide slightly more puncture resistance. Furthermore, PVC liners are relatively flexible, and you can use liner tape to seal together multiple sheets to fit the shape of your pond.

However, PVC pond liners have some significant drawbacks that make them uncommon in ponds. First, as a result of the manufacturing process, PVC pond liners frequently contain trace amounts of arsenic and other chemicals that are toxic to fish.

Resistant to Corrosive Chemicals

Corrosion is the loss or deterioration of a material’s (usually metal’s) properties as a result of electrochemical, chemical, and other reactions between the exposed material and its surroundings. If corrosion-control measures are not implemented, the condition of a storage tank may deteriorate.

PVC is an excellent material for installing a tank containment liner. Tank liners made of PVC are resistant to corrosive chemicals. They will not corrode or rust over time because they do not react with water and air in the same way that metal does.

Benefits of PVC Tank Liners

Choose PVC when looking for industrial tank liners for your storage tank. When you choose this type of tank liner, you will receive the following benefits:

  • PVC tank liners are extremely flexible. They have high interface friction without becoming textured and can easily conform to subgrade contours.
  • PVC is extremely abrasion resistant and has a high puncture strength. It is also resistant to a variety of industrial chemicals.
  • Installing a PVC tank liner allows your facility to save time that would otherwise be spent on-site fabricating and applying coatings.
  • Simple Installation – Many PVC liners can be installed in a single day. They’re also less difficult to build than a double-walled tank.


Corrosion occurs when a substance is acidic, basic, or oxidizing enough to dissolve the structure of an object. This can happen quickly or gradually over time. If the wrong material is used, the condition of a storage tank can quickly deteriorate. As a result, our custom fabrication process incorporates plasticized PVC, which is flexible, extremely durable, and simple to install when used as one of our flexible tank liners. Tank lining systems must be adaptable enough to conform to the internal contours of a tank and take on the shape of any environment, such as trenches and secondary containment areas. Durability is essential, especially when hazardous chemicals are present in the tank. PVC is extremely resistant to abrasion, punctures, and a wide range of industrial-grade chemicals.

PVC liner is a highly impermeable and malleable liner. It is one of the most trusted materials in the industry for water, chemical, and waste containment. Landfills, coal ash ponds, and stormwater management systems are examples of popular applications.

PVC, or polyvinyl chloride, is a white or light-colored solid synthetic rubber with a smooth finish. This type of liner, also known as vinyl, is resistant to abrasion, tears, gouges, and cuts. It doesn’t rot or become brittle with age, making it a good long-term investment. PVC is also chemically resistant, including acids, oils, and solvents. However, it’s not resistant to bases or strong acids.
