Like epoxy resin?

I have done some cattle troughs with stockboard, it expands a lot when the sun gets on it but otherwise it is very hygienic and the 12mm stuff although expensive stays on the bottom on its own.

For pigs I have used quarry tiles but they are very tricky to grout in and the company that made them (apparently the only one in the world) is no longer trading.  Pity as they are saliva proof.

If the concrete is just cracked or chipped at the edges you could try some screed which is made for the job. it would be the cheapest option, the concrete would have to be pressure washed clean first though.

www.hdsharman.co.uk gives you the link to the manufacturer of a product called Plygene. I have not checked out the site, but Plygene was used in the early 1990s for lining feed troughs. It was advertised in at least some of the farming press at that time. I have not used it, and rather surprised myself that I remembered the name of the product.
