Home is an older double brick / cavity brick construction in Sydney with bearer and joist foundation for the main house and single brick in the extended / back section (second photo, starting from the point where there is a vertical line running down the side of house)
The issue:
- There's a side garden next to our driveway with soil (images below) - about 7-8m long
- But it looks like the wet soil under the garden line is sitting directly against the foundation bricks (outer wall)
- When it rains, the water will drain down the soil but it looks like some water is getting trapped in the soil below the surface which is sitting next to the exposed bricks
- Climbed into the foundation and most of the inner and outer brick walls of the MAIN HOUSE seems dry - although I can't see the much of the outer wall through the cavity between the inner and outer walls
- BUT the inner walls at the end of this garden (EXTENDED / BACK SECTION) are very wet (last two photos)
The previous owner had this house for 10+ years and it doesn't seem like there are major issues, but is this something I need to fix? I am worried about the foundation sinking and structures of the house being damaged in the long run.
If yes, can I fix this myself or do I need to bring in a professional? Would I dig out all the soil and re-do the external render / cement / waterproofing?
Thank you!
