to level the floor,Mix a pva solution 50/50 and pour it on and brush it in,when the pva is tacky mix a self level compound and spread it on the floor.
The pva is a waterproof bonding sealant so it should do the job.

seeing as its nearly 2"out of level you can lay a polythene membrane down and then lay a 50-75mm screed on top
