Interior floor at same level as outdoor yard, best options for damp prevention?

    On one side of our house, we have both concrete and suspended wooden floors the same height as the concrete yard outside.
    It's an old solid brick house with no cavity so damp is always an issue but the floor level means it's much worse in those rooms.
    Previous owners had some DPC done but it's above floor level and not much use... The bottom of the wall still gets damp and then it just climbs the plaster.

    What could be a good way to try and manage this better?
    I'd considered a French drain or even just a channel to effectively lower the ground a few courses outside, maybe then use DryRod or DPC as low down as I can get. But don't want to do all that only to find it doesn't help
