Ponding curing works by keeping a layer of water on the concrete surface to maintain a saturated, high-humidity environment that promotes proper cement hydration and minimizes surface cracking. For this method to be practical, the slab needs to be essentially continuous and without joints that can act as leakage paths, and you must be able to build dams around the edges to hold the water in place and protect the base course from flooding. If there are joints, water can escape through them and the base could be flooded or washed, making ponding ineffective or damaging. The requirement isn’t that the base be dry; in fact, you want the surface to stay moist. So the statement is true because ponding cure is only practical when the slab is uninterrupted by joints and you can contain the water with dams to keep moisture on the surface without flooding the base.
