Tank Lining Process
Once cooled, the tank is inspected to determine its condition and whether or not relining is necessary. Sometimes looks may be deceiving as this tank need a lot of the cement lining removed. This is generally due to poor installation, be that too thin or improper surface preparation.
A small blister in the tanks lining may reveal a much bigger problem. A cement lining will blister when water has found its way beneath the lining. If water has gotten behind the lining, you can be certain your tank is corroding in that area.
The dark areas on the head of this tank show where water had spread behind the lining allowing the head to corrode.
The tank is first coated with a fast setting primer. The primer, being very thin is able to seep into any and every pore on the existing lining or corroded metal.
The first of sometimes 3 or 4 coats is then applied. Each of these stages are the same in application but particular attention needs to be taken for precise thickness of the epoxy.
Once applied in full, the entire lining becomes one seamless coating. We pay particular attention to get all inlets which eliminates the needless spending on anodes.
