Sand and hardcore (Turves Green B31)

A bit random, but I've just renovated my garden and have quite a lot of Sand lifted from below the laid slabs and hard-core dug up from the garden, before skipping I was wondering if anyone could make use?

The sand is bagged up into compost bags half full. Around 30 bags available. Happy to take part requests if you only need a bag or two (or just sand or rubble!)
