Water Tank Lining - Choosing The Right Material For Longevity

Water tanks are essential for various purposes, from storing drinking water to industrial applications. However, to ensure the longevity of these tanks and the quality of the stored water, it's crucial to choose the right water tank lining material. In this blog post, we'll explore the key considerations and options for water tank lining, with a focus on selecting the right material for your tanks long-term performance. But first, we'll dive into the basics on why water tank lining matters.

Why Water Tank Lining Matters


Water tank lining serves several critical purposes:

  1. Corrosion Protection: Lining materials act as a barrier between the tank's inner surface and the water it contains, preventing corrosion and rust. This is especially important for steel and concrete tanks.

  2. Preserving Water Quality: The lining material must be safe for the type of water stored. For potable water tanks, the lining should be food-grade and non-toxic, ensuring the water remains clean and safe to drink.

  3. Chemical Resistance: In industrial settings, where tanks may store chemicals, the lining material should be resistant to corrosion from these substances.

  4. Durability: The selected lining material should have the ability to withstand wear and tear over time, reducing maintenance and replacement costs.

Common Water Tank Lining Materials


Several materials are commonly used for water tank lining. Let's take a closer look at some of them:

  1. Epoxy Coatings: Epoxy lining is used due to its corrosion resistance. It forms a smooth, impermeable barrier and is used in the likes potable water tanks. Epoxy coatings are durable and provide long-term protection.

  2. Polyurethane Coatings: These coatings offer exceptional chemical resistance and durability. They are suitable for various applications, from industrial tanks to potable water storage. At Tank Reline, we've been using polyurethane coatings since 2011 and offer a 10 year guarantee following the provision of this coating.

  3. Cementitious Coatings: Ideal for concrete tanks, cementitious coatings bond well with the tank's surface and provide protection against water penetration and corrosion. They are also used for potable water storage.

  4. Fiberglass Reinforced Plastic (FRP) Lining: FRP combines fiberglass and resin to create a corrosion-resistant lining. It's versatile and can be used in tanks of various materials. FRP linings are durable and often used in the chemical industry.

  5. Rubber Linings: For tanks storing corrosive or abrasive substances, rubber linings provide adequate chemical resistance and physical protection.

  6. Glass-Fused-to-Steel (GFS) Lining: GFS tanks are made by fusing a glass layer to the steel tank structure. This creates a durable, corrosion-resistant and easy-to-clean lining. GFS tanks are ideal for various water storage applications.
