Storage tanks repairs: What is at stake?

LNG tanks, water tanks, digesters, silos -all such industrial structures are likely to need repairs and strengthening operations in order to:

  • Maintain the structure in operation;
  • Add capacity to account for loss of post-tensioning forces over time, and bring it back to the required level;
  • Add capacity due to higher loading levels;
  • Meet new standards;
  • Adapt the structure itself for a change of use.

How VSL can help you

In addition to monitoring, inspection and detection of slow and fast leaks, VSL can repair and strengthen all types of circular tanks:

  • Strengthening: integration of additional post-tensioning strands after measurement of the existing forces;
  • Concrete repairs, in particular cracks that causes leaks;
  • Repairs to the lining and coating on the inside;
  • Replacement of post-tensioning on the outside to strengthen or to replace tendons that have corroded.

Our expertise in repairs and strengthening of post-tensioned structures allows us to be flexible and to adapt to our client’s schedule on order to minimise disruption of service for any storage structure.
