What are different ways to waterproof your basement?

I have water pouring into my basement when we have a downpour and I am trying to find the different ways to waterproof a basement so that I can decide which is best for my house. Also, I would like to know what the cheapest way is.

If you have knowledge on the subject and could help me, I would greatly appreciate it.

Thank you!!!
