How Intanka® works:
Renewing Fuel Storage from the Inside Out

Diagram showing how Intanka tank lining works

Intanka® creates a completely new, structurally independent double-wall tank within the existing tank.

The new tank is constructed using reinforced fibreglass laminates, with a three-dimensional interstitial layer positioned between the primary and secondary containment walls. This monitored space provides early detection of any loss of containment.

The Intanka® process:

  1. Prepare the existing tank
    The tank is cleaned, inspected and prepared for installation.
  2. Construct the new tank system
    Reinforced fibreglass laminates are installed to form the new primary and secondary containment walls, separated by the interstitial layer.
  3. Test and monitor
    The completed system is tested and fitted with dedicated monitoring points for continuous interstitial monitoring.

Key benefits:

  • No tank removal
  • No removal of surrounding or contaminated fill
  • Structurally independent double-wall construction
  • Continuous interstitial monitoring

Future-proof your assets

Intanka®’s durable eight-layer fibreglass system is engineered for long-term performance and functional flexibility.

Intanka® can convert an existing tank into a multi-product storage system by installing a fully engineered structural steel bulkhead at the required location within the tank.

The dual structural skins provide robust, independent containment, while the monitored interstitial layer enables continuous leak detection and early warning of any loss of containment.
