Floor Flatness Levelness Testing / 3D Mapping
Metro Testing + Engineering incorporates the F-Number System for Floor Flatness (FF) and Floor Levelness (FL), developed by the American Concrete Institute (ACI), to evaluate horizontal concrete surfaces. This is typically done within 16 to 72 hours after final concrete finishing. A Dipstick Floor Profiler, a “robot-like walking machine,” is used to measure deviations in the elevation and surface of concrete slabs with speed, precision, and accuracy. In combination with enhanced profiler software tools, real-time data is used to calculate F-Numbers. Floor flatness and floor levelness provide useful information to the finishing quality of different crews.
- Real-time testing for flatness and levelness
- Accurate, timely and informative reports
- Assessment of slab deflections
- Assessment of post-tensioned slabs
