A section of this Castro Valley property retaining wall was leaning.
The three most common signs of imminent retaining wall failure are leaning, cracking and bulging.
The main cause of retaining wall failure is poor drainage at base of the retaining wall and no weep holes
A secondary cause of failure is not having a deep retaining wall footing (the concrete base in the ground that the wall sits on)
Engineering talk – When water accumulates behind a retaining wall, it pushes on the wall with a lot of force hydrostatic (water) pressure – thus the leaning section of retaining wall in the photo.
