Concrete Expansion Joints Under Pool

I am confused about the sand issue. Last year I used the Gorrilla pad and the pool tarp underneath. After a few swims I noticed where my cement underneath had lines, so did my pool.
So how do I place sand in these lines? Do I put the sand in wet or dry? The lines are less than 1/2 inch but the debris goes right in the lines so it is a pain for me with my suctioner. I need help!!!!
I think I would try using something else besides sand. I had a customer one time buy a case of silicone caulking and we filled the cracks in with that. It worked out great.
You could also cut some pieces of something like the Gorilla pad and put in the cracks. You could go over that with a layer of duck tape to hold it in place.
There are many different types of concrete fillers available that might work good also.
