Clean fill_sub-soil clay_2+ cubic yards (Barrhaven)

I have 2+ cubic yards of clean clay available for pickup in Barrhaven. Ideal for back-filling behind retaining walls, filling holes, pond building, structural base fill, etc. Not suitable for surface lawn leveling or gardening. I can move it to the base of my driveway for pickup if given some notice. The clay has been covered, so it is dry.
