Sealing Floating Slab gap

Is there a recommended method for sealing the gap between the floating slab and the wall.

I have a basement with floating slab that has a three quarter inch gap between the floor and the wall. This gap is between 3 and 6 inches deep and due to the high water table the mud on the bottom is constantly damp. I want to prevent objects from falling in the crack as well as prevent the moisture from coming out.

I have just waterproofed the wall with drylok as they had minimal seepage in extrem weather.

I would use an epoxy based joint sealer. Doubt if they will sell anything like this at Lowes or Home Depo. You will probably need to go to a Contractor supplier. I deon't know about your area, but here in NC we have places like General Materials, Guaranteed Supply, Specialty tools. These places all cater to the contractor rather than homeowners, but this doesn't mean you can't buy from them, you just won't find them around the corner from the hardware store. Call a local "Commercial" contractor, and ask them where they are buying their concrete and masonry accesories. They will help you out.
