Fixing damp in shed

oghran

I’ve got a 20 year old solid block built shed which has damp seeping under the walls. There is some kind of DPC (or just plastic?) between the concrete ground and the wall but I’m not sure it’s doing anything.

I’ve debated cementing along the join at the bottom of the wall, inside and outside to see if that would stop water moving under the wall.

Is there any other solution that might work to stop water soaking into the blocks and into the shed?

From the pictures it looks like the DPC is at the same level as the ground. Is that correct? Normally it should be above the ground level 10-15cm.
If so then its probably not doing its job because rain water will accumate and splash in the area. It also looks like the outside ground has dirt piling up against the wall which allows moisture to travel from the ground onto the brick.

would take up the concrete outside the shed. plaster the wall down below the yard level. then fit an aqua drain along it and cement up to them.
plaster on a plinth to help stop the water running down behind the aqua drain.
