Retaining Wall Failure Assessment
Engineer assessment of leaning, cracked or bulging retaining walls with cause, risk and repair or replacement design.
What the work involves
A failing retaining wall shows leaning, bulging, cracking, separated blocks or soil washing out. An engineer evaluates drainage, wall type, height, loads and soil to determine cause and urgency, then designs repair or replacement. Reports are also used in neighbor disputes and insurance claims, though many homeowner policies exclude earth movement.
