I've got a problem with the soil outside a stable getting eroded by the

Plastic grid tiles, which you infill with soil, gravel or grow turf
through. They're mostly sold for car hardstanding, to look better than
bare gravel, carry weight better than grass and drain through better
than tarmac. £20 /m^2 or so, Screwfix have them, or you can shop
around at real merchants for tougher ones.
