Measurement
The most common specification in Europe is the German DIN 15185 or its successor, the VDMA specification (FEM 10.2.14-1 / FEM 4.103-1), which is a sort of improved version of DIN 15185, where the short undulation of the floor over a distance of 10 cm is also measured.
DABROS Industrial Flooring specialises in measuring and correcting industrial floors to almost all specifications worldwide, starting with the aforementioned DIN 15185 and VDMA standards, we are able to measure floors to the British TR34 2013 and TR34 2003 standards, the European EN15620 standard and the American Fmin standard.
In addition, we also measure and correct the floor for Amazon, AutoStore, Exotec, GEEK+ systems. The measurement in this case is made with a super-precise 3D scanner or precision leveller, where the accuracy of the reading is 0.1mm.
Designed, constructed and built by us, the DABROS Digital Floor Profiler is characterised by an incredible measurement precision of up to 0.1mm and, most importantly, measurement repeatability.
The device has the ability to record measurement results every 2mm (required by the VDMA standard), however, the accepted rule is that a measurement every 5cm is sufficient to determine the quality of a completed industrial floor.
Once the sanding work is completed, the floor is re-measured to confirm whether the correction work carried out meets the specification.
Another method of floor correction, but is by far the most expensive solution, is machine grinding, which levels all floor irregularities almost to zero (by grinding).
With our DABROS Ultra Flat Floor Grinder, we can achieve ULTRA FLAT floors, where the difference in height between the wheels of the forklift does not exceed 1.0mm, and the longitudinal undulation of the running track is almost perfectly flat. A flat and even floor is of colossal importance in reducing forklift operating costs, increasing operator comfort and safety and increasing warehouse efficiency. As a result, ground floors meet the most stringent VDMA standards required by VNA system forklift manufacturers.
Grinding to the required specification
DABROS Floor Surveys Ltd is the absolute leader in Poland for the correction of industrial concrete floors, where compliance with the required specification is sought in areas where VNA reach trucks operate.
The most popular and least invasive method of correcting industrial flooring in the narrow aisle areas where VNA trucks operate is the ‘spot grinding’ method. In this method, we aim to achieve the required specification by grinding only those spots that exceed the permissible limit outlined by the required specification.
On the basis of the collected measurement results via the DABROS Digital Floor Profiler (or on the basis of third-party measurement results), the areas to be corrected are marked on the floor. These areas are then mechanically processed using special concrete grinders, which, in combination with high-performance hoovers, make the floor grinding process dust-free.
Thanks to the many years of experience of the staff and the professional operation of the grinders, the area to be grinded is characterised by an even bottom. Each sanded area is flat, with no abrupt bulges or depressions that can cause undesirable vibrations or oscillations to the forklift.
During the local sanding process, height differences between the wheels are continuously checked thanks to the DABROS Digital Checker, so that any errors are corrected in real time.
Once the sanding work is completed, the floor is re-measured to confirm whether the correction work carried out meets the specification.
