Testimonials
Akkerman has proven to be the “go-to” manufacturer of American Made TBM’s, GBM’s, and pipejacking systems. This is not just based on the 13+ years I’ve been doing business with them, but the nearly 40-years of successful partnering between Pacific Boring and Akkerman, a relationship I look forward to continuing.
