Maybe a long shot but need to partition my shed down the middle but not permanently. Was thinking concrete A section walling lifted in with telehandler, but thought why not buy my MOP up front and store down the middle. Lay a sheet over it. Only as deep as a bag at edges, heaped up in middle to 3 m. Will the bags slide out under pressure if only loaded one side initially? Ton bags better than 600 kg. Quite a polished finish on the store floor.
