Pouring cement to waterproof

Hi, I got a new home that has had issues with basement leaks (not really sure where its from). There's some cracks in the basement walls which the old owner seems to have patching with what looks like concrete
The basement was completely flooded and gutted a few years ago.

I was looking at either waterproofing the house (exterior), waterproofing (interior), or just pouring concrete. In would the last one be feasible assuming I am able to direct rain water to flow away from the property?

Concrete does not really waterproof anything. That's why your basement leaks in the first place. The proper way to waterproof in this part of the country is to excavate and apply a membrane to the exterior of the foundation. There are other methods that dont involve excavation, but they are simply mitigation... perimeter drains on the interior perimeter that lead to sump pumps to try and keep the water level below the floor at all times.

Step one is proper drainage... including gutters and downspouts that drain water away from the home... not dumping it at the base of your foundation. Then you need an appropriate slope away from the home. 1ft in 10 feet is a good amount.
