Interplex Etch Logic – Aboveground Storage Tank Restoration

CommTank proposed to clean, sand, prime and coat the interior of the aboveground processed wastewater tank. Before starting the work we prepared a confined space entry permit and a site-specific health and safety plan. We then entered the tank and installed a temporary floor and set up scaffolding. The crew power washed the inner walls to remove residual fluids and sandblasted the entire interior to the SSPC-SP5 profile (white metal finish). Crews cut out damaged sections of the tank and welded in new steel plates. After sanding and inspecting the repair welds we applied a scratch coat to the inner surfaces. When the primer dried we applied two coats of the expoxy. To confirm the tank coating consistency CommTank scanned the interior of the tank with a holiday meter. Any spots that failed the test were recoated to meet the manufacturers specification. The tank restoration was complete and the tank was placed back in operation.
