The DuctRunner technology is ideally suited to accurately measure the flatness and levelness of free movement or defined traffic floor surfaces such as industrial floors, slabs, runways, roads and sports arena floors.

A customer wished to know whether the floor of a warehouse he intended to purchase met the regulators’ flatness and levelness norms for installing high storage racks. The survey crew ran the DuctRunner probe along a predefined grid pattern in accordance with the customers’ planned layout.

Each path was approximately 56m/ 185ft long. The survey result of one of the paths shows that undulations occur in a band of about 30mm / 1.2”. Within that band, all smaller undulations are identified at sub mm accuracy. Survey results can easily be converted to the UK, US or German standards.
