Technology improvements on concrete screeds meet tight

Feb 23, 2021 · Other technologies making inroads in concrete screed use include 3D control systems, which allow contractors to input prepared designs into the computer and work with those plans to get the job done. For example, telescopic machines equipped with 3D systems can handle tasks that would have been considered a challenge in years past.
