Basement Floor Crack Video

At my lake cabin, I had indoor/outdoor carpet removed from my basement floor. I used a sander and sanded it smooth then applied garage apoxy paint that has specks you throw on top of the wet paint. After a rain I noticed clear water sitting on the freshly painted floor. I cleaned it up and it happened again after another rain. I noticed a hairline crack where the puddle was. What do I do? The apoxy paint is already on the floor!

Hey, So happy to have found your site. I am the building manager and handy man for the building I live in and need to address basement floor leaking. It's an old house and leaks significantly when we have noreasters. I have been looking up products and most address foundation or wall leaks. What is the best product for floor and wall leaks? I have diverted the gutters and spouts away from the foundation and it worked for a while. Not anymore. It is contributing to mold production. Need help.

My cement floor is heaved 1 to 1 1/2 were the crack is.Do I just cut it out and refill it with cement mix?
If I do this will it heave again in the future? If it is going to is there a way to stop it?
