Can a vinyl pool be placed on brick and or concrete?

You mean a cover like to close the pool over top of the water or a liner to hold the water.

To cover over the water, some companies make vinyl covers, they tend to be more expensive and heavier then woven ones though.

As far as a liner, some manufacturers choose not to make Vinyl Liners for concrete pools for different reasons. You'll have to check with a dealer in your area to find a supplier that does, or pursue other repair options.
