To address loose large floor tiles, first assess the stability of the tile and subfloor. Secure the tile with high-quality floor adhesive or mechanical fasteners if the subfloor is intact. If the subfloor is damaged, replace it before reattaching the tile. For persistent issues, consult a professional to avoid safety hazards or structural damage.

Large floor tiles are prone to loosening due to foot traffic, subfloor moisture, or improper installation. According to the National Floor Safety Institute (NFSI), floor-related accidents account for 10% of slip-and-fall incidents in commercial spaces, often linked to unstable tiles. The Tile Council of North America (TCNA) reports that 30% of tile failures stem from inadequate adhesive or subfloor preparation. Addressing loose tiles promptly prevents accidents and extends floor lifespan. For example, using TCNA-approved adhesives reduces failure risks by 40%, as cited in their 2022 technical guidelines. Cost-wise, repairing loose tiles early saves 60% compared to full replacement, per a 2023 study by the National Association of Home Builders (NAHB). Neglecting the issue can lead to tripping hazards, legal liabilities, or costly structural repairs, underscoring the importance of timely intervention.
