This paper addresses the urgent problem of improving the quality and extending the service life of industrial and residential floors. The study identifies common defects such as unacceptable vertical deformations, through and surface cracks, scaling, potholes, unevenness, destruction of shrinkage joints, and warping effects. Seven main causes are analyzed, including the absence of modern design and repair standards for high-strength floors, insufficient assessment of the concrete base, poor material selection, low-quality concrete, and non-compliance with technological requirements. The paper emphasizes the need for proper evaluation of tensile and flexural strength as primary performance indicators, rather than compressive strength alone. Recommendations include adopting standardized abrasion resistance assessment methods, selecting appropriate surface hardening materials based on load conditions, and ensuring compliance with curing procedures. Implementing these measures will enhance structural performance, reduce maintenance costs, and ensure long-term operational reliability in compliance with engineering best practices.
