Used 9 " hollow concrete blocks (Flintshire CH1)

I've got maybe 50 or so used blocks most with bits of mortar or render on them. In the past I've used these half buried in the ground for shed supports and they'll carry quite a weight and anchor things to the ground when buried. Could be used for raised planters, soil retaining wall etc. Collection from Sealand Road but if you want an 8x4 trailer full I might be able to deliver local to me
