Even though they are still nursing along the antique trailers, some have upgraded their concrete mixing and batching equipment over the years. But most are still relying on ready-mix technology that was developed during the 1980's! These old auger mixers replaced the original paddle-style mixer of the 60's, but were still extremely slow and very messy during clean-up. NOTE: These images were taken at a location that was shut down by the local government due to the environmental impacts from cleaning-out the auger over many years of operation. It cost the owner a huge fine, site remediation work and the loss of hundreds of thousands of dollars in sales.
Coming from the West, I was shocked to see so many of these old systems still working. It was like going back in time as I witnessed fleets of old tub trailers and rusting auger batch plants. By comparison, I could count on one hand the number of locations in California that would still have a single axle tub trailer rusting away in their bone yard. Today the portable ready-mix suppliers of the West use dry-batch loading systems and portable concrete mixing trailersthat are considerably more environmentally friendly and very efficient. What is also eye opening is that the sales volumes per location has grown faster in the West than in many of these other locations that still rely on the old technology.
To be fair to the Eastern ready-mix operators, there are some who have upgraded and use the modern technology, but they are still in the minority. What many of these operators do not realize is what great competitive risk that they face from others who would enter their markets with more efficient and desirable portable mixer systems. We have seen this happen many times in western communities.
