Grinding a concrete floor damaged by rain – renovation of a 12,000 m² area
Sudden rain showers during concrete finishing are a scenario that can ruin the top layer of any industrial floor. For our client in southern Germany, we carried out a rescue project covering a total of nearly 12,000 m² of concrete. Our collaboration began with a key task: restoring the technical and visual properties of a floor that had been eroded by a downpour.
The Challenge: Repair Instead of Expensive Coatings
The general contractor for the project initially considered applying floor coatings to cover up the damage. However, the client was looking for a more durable and natural finish. Grinding the concrete floor damaged by rain was the only method that allowed for:
- Removal of the weakened, porous surface layer (so-called “washed-out” concrete).
- Reaching the healthy, solid substrate.
- Proper surface preparation for the final polished finish.
The success of the test bed and long-term cooperation
Zaufanie inwestora zbudowaliśmy poprzez wykonanie profesjonalnego pola próbnego w systemie NORTEC®We earned the investor’s trust by creating a professional test area using the NORTEC® system. The positive feedback on the results of the concrete polishing led to a series of follow-up orders over the course of several years. In addition to restoring “rain-washed” surfaces, we also renovated old floors in the production facility and eliminated the dusting problem in the new service building.
Result: A durable, high-performance floor
Thanks to mechanical grinding and polishing technology, the customer received a uniform, wear-resistant, and easy-to-maintain floor, while avoiding the risk of paint peeling.
