    Abstract: Today's process of screeding, or evening out, wet concrete is an inefficient and arduous system requiring two (or more) men, a 2×4 wooden beam, and wooden forms to level the surface of wet concrete. The Obergfoll Concrete Screed Level, or “OCSL,” allows a single person to screed concrete as accurately, more easily and in less time than it takes the standard two man screeding technique used today. The OCSL is uniquely designed to allow a single person to accurately level and screed wet concrete. The screeding bar also incorporates a leveling bubble allowing for continuous verification of even leveling throughout the screeding process. The ergonomically designed dual handles act as convenient and efficient levers, allowing easy and accurate screeding of heavy wet concrete by one single operator, instead of the customary two or three person job.
