As the original inventor and with over 60 years of experience, Zimmerman Industries continues to lead the volumetric concrete industry with innovation, quality equipment and superior customer support. The Zim-Mixer brand – is the solution engineered for precision. Zim-Mixers carry all necessary materials – sand, stone, cement, water, and admixtures – in separate compartments. This allows you to dispense the exact quantities required on-site, virtually eliminating waste and providing unparalleled control over your mix designs. What sets the Zim-Mixer apart is its exclusive chain-driven design. This innovative approach ensures that each aggregate is dispensed independently, leading to minimal waste, simplified maintenance, and the highest accuracy available. We’re ready to custom design a Zim-Mixer to perfectly align with your operational requirements and business goals.
