My problem is water condenses from the stone slab in front of my house only when it rains how can I overcome this situatiion

This is not condensation, it is a leak. U can try to seal the stone but will make it slippery when wet.

Should have been sealed before stone was installed.

There tons of masonry/brick/Stone sealer that will prevent this and Won't make it slippery.
