ᐅ How can I waterproof the garage?

Hello forum members,

Our apartment includes a (very small) garage that we want to use as a storage room. The obvious problem is that a real fungus is now growing out of the wall (with a stem and cap, so a proper mushroom). The plaster is also deteriorating. My first thought was to install a horizontal damp-proof course using resin or similar. However, I have read that these barriers only have a very limited lifespan. What are your experiences with this? Alternatively, I could gradually support the roof and replace a row of bricks, adding some kind of intermediate layer. Which material would you recommend in this case and why?

However, this only solves part of the problem. The concrete floor is most likely affected as well. Since the shed stands exactly on the boundary with the neighbor’s property, I would need to dig in their garden to install a drainage system. I would like to avoid that if possible. Are there any alternative solutions?

Best regards

The floor is primed and covered with a waterproof membrane, but this does not replace the missing horizontal damp-proof course in the masonry.
