you MAY be right but just be advised that water has already created little underground runways leading down to your bsmnt so, if its wtr under the slab/pavers, you're sol,,, that being said, often polymeric sand's used in pavers to hold them in place,,, i've noticed it also seals the pavers & prevents a design'd use ( that of being permeable pavement )
sealing those crack properly would be good advice if you like more free stuff
