The facility is a large 900 m² covered warehouse being converted into a production space. The main challenge was to create a hard-wearing, aesthetically pleasing and durable floor to meet the customer's high performance requirements
The customer asked to restore and reinforce the existing concrete base using the Polished Concrete technology. The main requirements were high durability, resistance to mechanical loads and abrasion, as well as reduction of dust generation in the room. An important criterion was the speed of work execution, as the production start-up was planned within a short timeframe
The project utilized advanced BIM modeling and laser scanning techniques to accurately assess the condition of the subgrade and optimize work planning. The main focus was on the quality of subgrade preparation, selection of materials for future maintenance tasks and adherence to concrete polishing techniques to ensure high performance of the pavement
To achieve the required characteristics of the coating, the "Polished Concrete" technology was used, including mechanical treatment of the concrete base, impregnation with hardening compounds and finishing polishing. The key stages of work were performed using industrial grinding equipment with diamond tools of various grit sizes. The use of specialized hardeners and sealing compounds made it possible to achieve high density and wear resistance of the coating.
Prior to the start of the work, preliminary laser scanning, desktop data processing and BIM model creation were carried out, which allowed for detailed planning of the renovation process and the adoption of several important design improvements individualized to the client's needs
At the beginning of the work, a detailed diagnosis of the condition of the concrete floor was performed using laser scanning. Our team prepared samples of the finish coating, which were agreed with the customer
After diagnostics, desktop processing of scanning data and BIM modeling were carried out, which allowed to plan repair works in detail, determine the optimal technology of applying protective compositions and stages of works
Based on the approved decision, rough mechanical grinding of the surface was carried out to remove the weak top layer and level the substrate
The next stage was the application of a deep impregnation hardening compound to strengthen the concrete structure and prevent further dust formation. Epoxy primer in combination with quartz sand was used to repair cracks, which effectively sealed the defects and prevented further destruction of the coating. The restoration of inter-tile joints was also carried out using a two-component polyurethane sealant
At the final stage, the surface was sanded to a design level of #Grit, including hand finishing of wall and column junctions. To further protect and extend the life of the coating, a chemical polish was applied, giving the floor an aesthetic appearance, smoothness and increased resistance to contamination
