Why should I engage an engineer?
A structural engineer can identify the loads subjected to retaining walls and determine their adequacy.
Should you be constructing a new, or repairing an existing retaining wall, a structural engineer should be engaged to check its structural adequacy.
Many existing retaining walls do not comply with current regulations and do not meet long term serviceability requirements. A noncompliant retaining wall may collapse, particularly after heavy rain, or after undermining the base of the wall, or by increased loads behind the wall.
