Options:

ProBase Anchor Blocks help lock your building to the grids. In windy conditions lightweight buildings with few contents inside can slide off plastic bases or can even be completely overturned by the wind.

ProBase French Drains are designed to create a drain along two sides of your building. This stops rain water splash back and prevents soil particles building up on your timbers which can lead to timber rot.

    Bought the two together for a 5×3 m base.
    Digging out for sub base then sand base took a while to get dead level. Then assembling the grid base quite quick. Will be back for another base when I enlarge my workshop. Good product
