Over the past six months, a lateral crack has developed in a concrete block foundation wall below grade. Above grade is a brick veneer, one story rancher built in the 1970s. The wall has moved 20 thousands of an inch as measured by a dial micrometer in the past six months. A few weeks ago it measured 17 thousands.
Is this an area of concern and what can be done? Who should we contact – home inspector, structural engineer, architect, contractor?
Thanks. We look forward to your reply.
