I'm not a specialist, but from my experience so far, every earth-covered underground structure (underground parking, subway station etc.) will eventually start leaking (exceptions might apply to really dry locations of course). It might last 40 years instead of 30 with better construction quality, but eventually you will have to dig it out (in part or fully) and repair it - which is obviously costly, especially if you have landscaping at ground level.
- ekr 6y agoIsn't that true of any building though? Where I live most houses have ceramic roof tiles, and even though they are supposedly long-lasting, after 60-80 years they do need replacing (most home-owners replace them much more frequently, every 10-20 years). I've replaced tiles on my grandparents' house which was around 60 years old, because they became brittle and started cracking after hundreds of temperature cycles, hailstorms etc.
