Is efflorescence common

I'm investigating concrete block options for a retaining wall project. I spoke with a local Versa-Lok dealer and when I brought up the problem of efflorescence, he said all manufacturers have this problem?

Is this true? I guess I believed this problem was specific to Versa-Lok.

I don't know about Versa-Lok but efflorescence is always an issue if moisture can migrate thru masonry.

Efflorescence is not a possibility just with Versalok since it's possibility depends on the conditions and backfill behind the wall. All of the 4 different major SWR units/systems are made in similar manufacturing systems in the plants they are produced in, but the major licensors do a good job of assisting the manufacturers in production of quality units, while the "knock-off" copy units can be questionable.

Just use a well drain material as a backfill behind the wall and provide drainage.
