I'm moving my stuff into a storage space that is along a retaining wall that has leaked before. (They've filled the cracks with sealant.)

Knowing this I plan to put Rubbermaid bins along the back wall, but I have some cardboard boxes I need to store in that space.

Will a drainage mat be enough (most seem to be 1.5-2.2cm,.6"-.9" high)? Or do I need to get actual metal or plastic pallets that are taller (3-10cm, 1"-4")?

It's a storage space in the underground parking deck, so I doubt it will flood (and there are lower places for water to pool if it does). But if that back wall leaks there maybe be some water on the floor.

Suggestions?

Will a drainage mat that's 15mm/.6" be enough? Or do I need to get actual metal or plastic pallets that are taller (3-10cm/1"-4")?

It's a storage space in an apartment building, so I doubt it will flood - but if that back wall leaks there maybe be some water on the floor.
