Hi all,
I'm building a retaining wall (gabion) that, when back filled, will result in a section of my house wall being underground. The external wall is rendered (bit damaged but i'm fixing that). Will render alone suffice if its now underground to prevent damp getting in, or do I need to be doing something else?
Its impossible for me to tell what sort of damp proofing has been undertaken inside the house without ripping out panelling. Any advice is much appreciated.
