Retaining walls is crucial for keeping the safety and stability of a property. However, it is common for homeowners to miss early signs of impairment, which can lead to more significant issues later on. One stark reminder of the importance of inspection is the collapse of Wall 22 in Bellmawr, New Jersey, in 2021. Although there were reported warning signs before the incident, the condition of the retaining wall was not addressed, resulting in its instability and eventual destruction.
This event serves as a clear example of what can occur when retaining walls are neglected. Inspecting and determining early warning signs of damage can deter such disasters and help preserve the integrity and safety of a structure.
One of the most common signs of a damaged retaining wall is cracking. Cracks and fissures arise due to water penetration behind the wall, as well as failure to withstand the weight of soil. If left unchecked, these cracks can weaken the wall’s structure, letting water infiltrate and further impair the foundation.
Tilting is another sign of distress. When a retaining wall leans, it signals excessive pressure from retained soil or water buildup. If the leaning is not fixed, the wall may eventually collapse, creating a hazardous situation for the surrounding area.
Water accumulation around a retaining wall is also a red flag. Standing water signifies that the drainage system is compromised. Over time, this can deteriorate the structure and increase the likelihood of collapsing.
Bulging is another indicator that a retaining wall is under tension. This happens when the wall is pushed outward due to water or soil pressure. As a result, the retaining wall’s structural integrity is compromised, wherein the surface appears to be uneven, with visible protrusions and dips. If not addressed promptly, bulging can also lead to wall cracks and collapse.
To identify these warning signs, a NJ structural engineer needs to conduct a professional inspection. These professionals can examine and recommend some timely repairs before the damage becomes severe.
Owners can request the assessment of retaining walls in conjunction with commercial building inspections NJ. This is the best way to maintain the safety and value of the landscape while conserving time and money and reducing the risk of costly repairs.
