Concrete Fuel Storage Tanks

Concrete Fuel Storage Tanks Envirosafe™ Above Ground Fuel Systems has said many times that double wall steel above ground fuel storage tanks are more convenient, economical, and cost effective than concrete vaulted tanks. Now we would like to put our money where our tank is.

Below is a comparison of our Fireguard above ground double wall steel fuel storage tank to a concrete vaulted tank. Review the information and you be the judge.

Fireguard Steel Tanks Feature:

  • On-site secondary containment testing using standard, economical testing procedure
  • Concrete primary tank is enclosed by an impermeable, crack resistant steel outer tank
  • Secondary steel containment provides added strength, security, and is easily recycled
  • Fireguard uses a lightweight monolithic thermal insulation material – specialized concrete – that is part of a patented process resulting in a lighter material weight than traditional concrete

Concrete Vaulted Fuel Storage Tanks

  • Concrete Fuel TanksSecondary containment on certain tank designs may require elaborate and expensive procedures for on-site testing
  • Exposed outer concrete wall is susceptible to cracking, spalling, and weathering, which are expensive to correct and not typically covered by warranty
  • Polyethylene sheeting depends on concrete for strength and takes years to decompose
  • An average 12,000 gallon concrete vaulted tank weighs approximately 50 tons increasing the costs of tank relocation and transportation

Main Causes of Cracking Spalling, and Weathering of Concrete Vaulted Tanks:

  • Weathering – Due to carbon emissions, rain is usually slightly acidic, and it will etch and pit concrete over time.
  • Cracking – Swings in temperature causes slight expansion and contraction of the concrete used in vaults.  Over time this expansion and contraction can lead to cracks.  Moisture can enter these cracks.  In the winter the moisture freezes and expands, forcing the crack to open further.  When the weather warms, the water melts and relieves pressure within the crack.  As the crack relaxes fine fractures form at the edges of the cracks.  Over time, this expansion and contraction causes the crack to grow more and more.
  • Spalling – Spalling is caused by a combination of weathering and cracking.  Sometimes when pitting and cracking are allowed to go on long enough, they weaken the concrete enough to cause chunks of it to fall off of the tank.

The Envirosafe™ Advantage

Weathering, cracking, and spalling can be costly to repair – especially when the damage is severe.  In some cases, the tanks may even need to be replaced altogether – an extremely expensive procedure.

With double wall steel above ground fuel storage tanks, maintenance is greatly reduced as is the potential for major repairs down the line
