Under ground tanks are specially designed to be stored beneath the ground. Their design is similar to above ground tanks, but their placement is different. Under ground tanks require many precautionary and preventative measures to prolong the service life, such as Cathodic Protection, Tank Coating and Backfill, so make sure to ensure general maintenance and protect your tank.

• Cathodic Protection – To protect a tank from electrical currents and deterioration, it is put in an anode bag to absorb the currents and reduce damage to the container. The bag acts as a decoy for harmful electrical currents in an under ground environment.
• Tank Coating – To protect the tank during installation as well as increasing the life of an under ground tank it is coated with a protective material to persist in tough outdoor environmental conditions.
• Backfill – This material is made of sand or firm earth, free of rocks and abrasive materials, so that it does not cause abrasions to the tank wall or cut through the anode bag to cover an under ground tank after installation.
