What to Know About Tank Lining

Tank lining plays a critical role in maintaining the performance, safety, and longevity of water storage systems. Whether you manage tanks for fire protection, potable water, or industrial processes, understanding how tank lining works can help you make informed decisions. 

What Is Tank Lining? 

Tank lining refers to the installation of a flexible membrane or coating inside an existing tank. Its purpose is to create a watertight barrier that prevents corrosion, protects the tank structure, and keeps the contents uncontaminated. 

At Franklin Hodge, we install tailor-made linings that are fitted within your current tank to restore its integrity and performance. These linings are commonly used when a tank’s original coating has deteriorated due to age, chemical exposure, or environmental factors. 

Lining Materials, We Use 

Franklin Hodge offers linings made from high-quality synthetic materials, including: 

• Butyl Rubber – WRAS-approved and ideal for potable water storage 
• EPDM – Highly elastic and resistant to wear and UV exposure 
• PVC – A versatile option for various non-potable water applications 

Each liner is custom fabricated to match your tank’s size and layout, ensuring a snug fit and long-lasting performance. 

Benefits of Tank Lining

• Corrosion Protection – Prevents rust and metal degradation 
• Leak Prevention – Creates an impermeable seal that holds up over time 
• Extended Tank Life – Revitalises older tanks without the need for full replacement 
• Regulatory Compliance – Materials meet UK and international safety standards 
• Minimal Disruption – Installation can often be completed without major system downtime
