How can I fix cracks in the basement caused by flooding?

My house flooded three times after storms and power outages for the pump wasn't working. Our pump has a back up now but the cracks are there and some are growing in length. I called a professional(more than one) 3 years ago. Quite expensive, and delays and more delays until I had to take care of another emergency and used the money I had for the repairs. Reading different solutions for the basement cracks, read about kits to fill the cracks(epoxy I believe) another solution, some kind of membrane. Anyway I decided to take care of it myself, one way or another. Can anyone tell me what works (I cleaned the floor well, even removed the side boards for it was a finished basement, I can see the outside wall covered with black substance, tar?Will appreciate any positive input.

    Hello there, Get your property checked out, if you say these cracks are getting bigger. It may need underpinning! Do you have Insurance, if so get them involved!

      Thanks but we tried with cement patch in one place as a test. Didn't solve the problem.

    We have used a product called drylock. Rolled it on walls and floors when our sump pump stopped working very effective inside and also outside

      Thanks I have one bucket left, at first seemed would solve the problem but the house is old has one sump pump and side drainage. Apparently the previous owner had the problem and attempted to hide it, In fact cover the baseboards with a vinyl so I think, when we removed it, we found the wall wood was rotten at the base. It hasn't flooded again since we saved and bought a generator to keep the sump pump working. I wanted to do it myself but as I listen to you all, I'd better call the Professional and see if anything else is going on since now the sum pump works constantly.

      Thanks so much for the advice.
