Can you? Sure. It's your basement. But think back. Has it ever had a wet corner after a big storm? A damp smell in the summer? If so, putting up walls now just hides the problem behind new drywall, and you'll pay to tear it out later. Water first. Walls after.
Look at what a finished basement is made of. Drywall. Fiberglass. Carpet. Wood studs. Not one of those likes getting wet. And if you ever need an interior drain, it goes in along the very edge of the floor, where the wall meets the footing. That's exactly where your new wall would be sitting.
Can you finish a basement before waterproofing it? The order to follow: water signs, moisture test, grading, inspection, radon and the right materials.
