A swimming pool was built on the concrete floor. What if there is a leak under the pool?

I can tell you directly that it can't be repaired, and it will be leaked soon after the temporary solution. It will cost a little money to do it according to my method, but it will solve the problem.

The first step is to remove the original cement layer of the pool.

Be sure to smash them all, leaving nothing behind. If there is a joint between the old and new cement, it will still leak, so don't leave anything after it is completely smashed.

Step 2: Brush a layer of waterproof paint on the cement floor.

Your cement floor is not waterproof, so apply waterproof paint first.

The third step is to repaint the cement mortar.

Mix sand, cement and waterproof powder according to the ratio of 1:2: 1, and use this cement mortar to wipe the pool again. The thickness is not less than 1 cm.

Step four, brush the waterproof coating for the second time.

After the cement mortar is completely solidified and dried, we will brush the second layer of waterproof coating.

Step 5, add a protective layer.

Use cement-based waterproof slurry to add protective layer to waterproof coating.

After these five steps, your cement can be guaranteed to be watertight. You just built a swimming pool without waterproof, which is unacceptable. It is 100% waterproof. The right thing to do is to do as I do. It is king to make several layers of waterproof to ensure no leakage.
