Anyone ever used any of the plastic shed bases that you fill with gravel?
Mine needs a rebuilt as the previous owner seems to have thrown it down onto soil and it is gradually warping, rotting and falling apart. I was thinking about building my own. Concrete base seems the best, but expensive. Other options are flag stones, flag stones with a hard core layer underneath, or a post and pier system (knock posts in, boards between).
Any tips on the best type to go for?
I saw a new product recently which is designed for decking. It’s a concrete block which has a cruciform recess to take either horizontal or vertical posts. You’d lay these onto a bed of suitable mortar then build a sub frame in timber so the shed is elevated slightly.
