Concrete Dobies
Our plain dobies range in size from 2 x 2 x 3/4” up to 5” and 6” in dobies. The term “dobies” has become the trade name for concrete rebar supports over these last fifty years. They come with, or without tie wire inserted in the concrete brick. We manufacture these in regular strength, 4000 psi mix design, or higher strength for specific jobs.

Concrete Construction During Economic Uncertainty
As we deal with tough and unsure times, developments and improvements keep the concrete market moving forward. These have certainly been a few of the strangest and most difficult days modern Americans have ever faced. While some concrete contractors have had the fortune to keep working despite the pandemic quarantine, others have seen tasks halted. Whether you’re working consistently or trying to find out how to jump-start your business upon a return to normalcy, now might be an exceptional time to learn more about the current technologies, innovations, developments, and skilled ideas that are driving the industry forward. New Technologies: Robotics, Big Data, and More From robotic demolition that allows big work in tight spaces to state-of-the-art atomized dust suppression machines, brand-new technological innovations increase
The Do’s and Don’ts of Tying Rebar
At a glance, the process of tying rebar may look easy. However, the reality is that is it quite a lengthy and complicated process. While it isn’t exactly rocket science, there are still a lot of things one needs to take into consideration when tying rebar. Do it improperly, and you risk endangering the entire integrity of a structure. In this short guide, we highlight the dos and don’ts of tying rebar. The Dos Do Your Homework Do your homework on what sizes, configuration, and placement of rebar will be required, as well as what type of chairs would be best for the job. Both concrete and plastic chairs have their pros and cons, and it will depend on your situation and budget in deciding
