Tank Double Bottom / El Segundo Bottom Repair
Many tanks are mandated to add leak detection and secondary containment when tank inspection dates are reached. Double bottom tanks are recognized by API and the U.S. Environmental Protection Agency as an effective release prevention barrier (RPB), a type of secondary containment. A double bottom repair uses a new steel bottom on top of the existing steel bottom, separated by an impermeable liner and concrete. The separating material can also be sand with cathodic protection embedded. Slots or grooves in the concrete allow the tank operator to monitor for leaks. This design is also known also known as an El Segundo tank bottom.
