At first glance, some thought it wasn't actually holding back the soil—but technical analysis revealed the opposite: the pressure from the ground had caused the structure to collapse. 👉 Problems identified: Hollow concrete blocks unsuitable for retaining walls Insufficient reinforcement No structural ties Foundation too weak (25 cm without reinforcement) No rear drainage Water pressure accumulated in the soil Result: Compromised stability and risk of collapse. We have therefore decided to completely demolish the structure and rebuild a proper retaining wall using concrete blocks, reinforced concrete, a reinforced foundation, and rear drainage.
