Repairing a gravel board?

Hi all,

i hired a mini digger last week, i managed to steer clear of the walls etc around the perimeter while i dug the whole garden up. However as i was reversing the digger out I clipped and damaged a concrete gravel board which sits underneath the panel fence between my house and my neighbours.

I need to either replace or repair the board. the board has a single fracture running vertically down the centre from top to bottom and is slightly bent in the centre.

is this repairable or do I need a replacement panel?

Probably better off replacing it as it would be more hassle to repair.
