how it helps you

You have probably seen a barrel mixer on the highway. Those trucks always have to keep the drum rolling to keep the concrete mix moving, otherwise it hardens. This takes up a lot of valuable time. 

When we use our volumetric concrete mixers from Cemen Tech, we don’t have to keep a drum moving to get a thorough mix. All we have to do is load all the materials in different compartments, come directly to your site, and mix it right there. In 10 seconds, we have concrete thoroughly mixed to perfection.

You get your concrete delivered quickly and we can keep moving with the day. This ensures that everyone gets their concrete! You don’t have to wait any more for your contractor to squeeze in some time for you. Holzer Sitemix ensures you get your project done on time and to your preference.
