Profile: Basic Concepts introduced a unique way to allow rainwater to drain from the sentry portable secondary containment berms without allowing harmful hydrocarbons from being discharged. Petro-Pipe™ device is offered for portable secondary containment through our company. The new Decon berm features foldable wall partitions that make it excellent for space constraints on emergency response vehicles. The Fail-Safe™ berm utilizes outside supports with a new skid plate and floatation system, which allows the entry and exit, walls to rise with the liquid level.
