Broken chalk spoil (East Blatchington BN25)

We have a massive (10 cubic meters +, I'd estimate) pile of chalk spoil from building work in our front garden. There is a little soil, flint and miscellaneous small hardcore mixed in, but I'd say it's at least 80% chalk. We also have around 20 rubble bags filled up with same. You are welcome to help yourself at any time, but please leave the pile tidy and off the surrounding grass. Thank you!
