repairing leak between two concrete surfaces?

I have a small basement that has two levels, one about 3 inches lower than the other. There is a 4 inch concrete berm between the two levels...because the higher level floods a little bit when it rains. The basement floor is old concrete, and the concrete berm was placed on top of the floor more recently, probably just built between two pieces of wood, with little preparation. . Recently, water has been leaking under one side of the concrete berm and I'd like to find a way to stop the leak temporarily but I don't know what kind of concrete, or sealer would work best in this situation.. There is no obvious crack, so I'm thinking I'd just smooth the concrete or sealer along the joining area between the two planes. of concrete .

I have some Quikrete, would it work as a temporary seal if I smoothed it on without grinding out a slot . There is rain coming in a few days so a temporary fix would be fine...or is Quikcrete without grinding a slot a waste of time?

I'd appreciate hearing any suggestions or ideas for a temporary fix for this problem.

I know of no simple paint on, caulk or mortar that works. You need to prevent the water from entering the home. Anything you do on the inside to try and stop the water after it's already inside will fail. Read up on how to make a dry basement. Start by making sure you house has working gutters and downspouts and that they direct the water far away from the house. Make sure all the land surrounding the home slopes away to keep surface water away from the home. If that doesn't work then there will be some digging.

So this is something like a speed bump on the floor?

This might be a good application for Dry Lok paint on waterproof pant!

It's best you take a picture. There's cement and there's concrete. Concrete is with gravel. And there must be a thickness to concrete. atleast 2 or 3 inches.
