DPC old Conservatory base

[davey7897]

Basicly I've removed my old conservatory in spring I was going to remove the concrete base as well but damaged my back when doing this. So over the summer I just laid square decking tiles over the old base to tidy it up in the knowledge I'd have to remove them and the base soon as its a brick above the damp proof course.
My question is could I use dry rods to heighten the damp proof course of the wall ? I quite like where the decking is and it would be easier to do this rather than removing the whole lot.
Any advice would be a great help.

Thanks
