Excessive moisture

Hi all, I am new to this forum. Recently I have encountered the following problem.

Problem: excessive moisture in walls, causing damages

Climate: Mediterranean

Situation: the problem concerns walls in a small (8x2x5 feets approx)
unused (and not livable, with the only function to facilitate air flow and block humidity)
room below ground level, under a grassy area.

1. all its walls are wet when raining due to moisture
2. plaster is visibly damaged in several points. Bricks are visible in few spots, where the plaster has been completely destroyed
3. bitumen/pave coating is severely damaged too, and during raining,
water comes out
4. the right side wall (marked with red arrow) seems suffering
from moisture coming up from below, as
it contains spots where crystalized salt can be seen

During raining, water accumulates in the room.

The right side wall (the region marked with the red arrow)
is partially shared with the basement, and its opposite side
(i.e. the side inside the basement) is bent due to moisture,
with some tiles broken.

What are the best solutions to this problem?

Thank you

If all that black crap is mold, get it eliminated asap. Soap and water, followed by bleach or another mold-killing product, and don't be afraid to call in someone who has the equipment to breathe with all that being disturbed; it could kill you. Neither the mold nor the bleach is the best thing to breathe, esp in a small room. Then, always start with the outside, diverting rain away from the building. You may have to dig up and install gravel, "waterproof" the outside, and install drains along the bottom of the building, too. Can that water be run to daylight anywhere? You have a very nasty looking situation there, and it may be a job for the Marines, as it were.
