Damp shed wall

Edk008

Hi folks recently got a shed built and the back wall is shared between myself and neighbor but his garden is higher ground level than mine.... This is leading to damp creeping through on my back wall at his ground level.... Any help greatly appreciated as I haven't a clue how to go about sorting this...

How high is his ground level above your floor level?

Around 3 foot above my shed floor level I'd say

I think you're going to need to talk nicely to your neighbour about trenching along that wall on his side and at least putting in some drainage (e.g. pea gravel over French drain) to relieve the hydrostatic pressure which is forcing moisture through the shed wall.

Not entirely clear whether the boundary wall existed before the shed, or whether the shed created the wall.

I agree with Lumen.
Also, if the neighbour allows you to make a drain, why not ask if you could plaster the wall from foundation to ground level on his side at the back of your shed. That, along with the drain, should leave you safe.

Thanks for the advice... The wall was already there and he built his shed off it first now I have...

How is the run off from the shed roofs being dealt with?
