I would rent a good “industrial dehumidifier” they all take electricity and it can take well over 7 days to dry out a room with a professional unit. They are big and noisy. But they do the job quick and could save lifting the floor all together. You may be shocked at the amount of water a good unit can lift in a hour, never mind a day. if you stop the flow of water, it’s time critical to save/avoid further warping/damage etc.
Rented dehumidifiers aren’t really that expensive to hire. Sometimes you can strike a deal too.
