Just about to take delivery of an Intex 15' diameter above ground pool -
one of the metal frame and liner type. As the garden slopes, I need to
create a level decking to sit the pool on.

No you don't. For this sort of weight you need to dig and then pour proper
concrete foundations. Re-inforcing them with steel might also be needed
depending on the slope and soil composition. Get a structural engineer
round ASAP.
