Testimonials
Super Excavators, Inc. has enjoyed a long partnership with Akkerman over the years. We originally bought a competitor’s microtunnel system and had nothing but problems with quality and service. Finally we called Akkerman and bought their SL36 microtunnel system. Since then we have never looked back. We have bought several other pieces of equipment from Akkerman. From GBM equipment to ABIS to several microtunnel cutting heads. They have been great working with our staff to customize the equipment for our specific needs. We have put their equipment to the test on several projects by pushing the envelope in long drive distances and very difficult ground conditions. The equipment has responded well and together we have made modifications to continue to improve on efficiency. In our business it is necessary to have people their when you need them. Akkerman has done a great job at supplying quality equipment and servicing our needs in a timely matter, helping keep our work on schedule.
