Pigs will get stuck in cement and sand can cause itchyness. Dirt (esp mud) is the best for pigs
ppc cement
you can but it would be best to put a layer of sand under the liner to protect it from the hard cement. Otherwise you may end up with a damaged liner.
Although put together by humans, the parts of cement are natural. Cement is a fine, soft, powdery-type substance. It is made from a mixture of natural rocks: limestone, clay, sand and/or shale. When cement is mixed with water, it can bind sand and gravel into a hard, solid mass called concrete.
Asphalt is the thickest part of crude oil after all the lighter parts have been refined out of it. Mixed with sand and small gravel it is put down, compacted and get hard when it cools. The oil hold the sand and gravel in place, but it is not a cement like glue.
Swimming pools can have many types of bottoms. Most are cement or dirt. So if its cement and bumpy its probably wearing and the same if its dirt. When the pool was put in on top of the dirt is sand usually so the sand has shifted. The water stays in because most pools have liners.
This is how i would do it: 1 get a permit 2 dig a hold 3 cement it 4 wait for the cement to get hard 5 put sand in 6 put plants in 7 put filter and heater 8 add water 9 inspect it and add all decorations 10 add fish

If you have enough sand you should just put sand in the bottom. It is like a bath for them and keeps them clean.

The only bloat I've seen in pigs is actually a twisted gut, and there is no cure. The animal should be put down.
You are going to have to tear some of it up to put the pool in. the rest would depend on the strength of the concrete you have on the ground. If it is reasonably strong you could cover it with something like 20mm ply to protect it from the machinery operating on it during the building and hope for the best.
