Polished concrete floor as a durable work floor

In the spring of 2025, Kuster Betonpolish and Blinkers Vloeronderhoud worked together to make the workshop floors of approximately 2,200 m² at Goburg Metaalbewerking in Ossendrecht suitable as a workshop. In the new hall, the concrete floor was polished; in the existing hall, the floor was renovated by removing the old coating. The company opted for a polished concrete floor as an alternative to the existing coating floor, which proved unable to withstand the intensive use within the metalworking company. 

Goburg Metalworking is a family business that has been active in turning, milling and industrial maintenance for over thirty years, with a clientele ranging from the automotive to the offshore industry and everything in between. When working, a clean, easy-to-maintain environment is key. "Our existing floor had a coating, but it was regularly coming off due to mechanical stress," says Erik Govaarts, director of Goburg. "We work with liquids such as refrigerants, and when they flow under the cracks, the coating loosens even further. Locally sealing the cast floor coating gave color differences each time and the floor was difficult to keep clean. We wanted a solution that was more technically satisfactory and visually calmer looking."

Reinforcing concrete floors

At a fellow company, Govaarts saw the benefits of polished concrete floors. He ended up with Blinkers Vloeronderhoud and Kuster Betonpolish. Together they drew up a Plan of Action. "We specialize in sustainably reinforcing concrete floors," explains owner Marcel Kuster. "By sanding the concrete, chemically compacting it, then polishing and impregnating it with a silicate-based stain stopper, the surface becomes harder and denser. This prevents dust formation and makes the floor more resistant to liquids."

Sanding, compacting and polishing

In the existing part of the workshop, the old coating was first completely removed. Then the concrete was sanded, compacted and polished in several passes. In the adjacent new construction hall, the floor was already treated according to the same principle during the finishing phase. Govaarts is satisfied with the preparation: "Several test surfaces were applied, each with a different finish and impregnation. This allowed us to assess on site what best suited our use and preferences." According to Kuster, that process is essential in industrial environments. "Every floor is different and the use load varies from company to company. By applying test surfaces, we can show in advance what effect different treatments will have on the appearance, gloss level and dirt resistance." Implementation went according to schedule and in good consultation, Govaarts said. "The communication with Rudolph Streppel of Blinkers Floor Maintenance was clear and agreements were kept. That is not a given in this market, and important to us in a production environment where downtime directly affects the work process."

Renewed floor: hard and dense

The result is a level floor with increased light reflection and improved cleanability. Kuster: "This process makes the floor hard - as much as eight times as hard because of the chemical compaction - and dense. As a result, you have less dust formation and the floor has better water and stain resistance. You can clean the floor properly from now on and keep it beautiful that way." For Goburg, the new floor means an improved basis for the production process. "We were looking for a solution that is technically and aesthetically right and proves itself in practice," says Govaarts. "We are happy with the result."
