        "text": "Subfloor prep starts with testing the concrete slab for moisture and assessing how level it is. Any previous flooring adhesives, dirt, or loose debris must be scraped away. Low spots need patching compound or self-leveling underlayment, while high ridges require mechanical grinding to achieve a flat surface within manufacturer tolerances. Cracks in the foundation slab should be filled to prevent movement. Depending on the final floor covering chosen, installing an approved vapor barrier or dimpled subfloor membrane helps protect against rising ground dampness.",
