The Problem

Backfill settlement in new construction can cause the electrical service box to rip from the wall, resulting in potential exposure of service wires. It is common knowledge in our field that problems can develop with the connection of underground electric service to building structures. Specifically, problems have developed from the settling of backfill over the electrical conduit. It is not unusual for the backfill to settle from several inches up to a foot or more, along with the conduit surrounding the service. This shifting can expose service wires and cause the building service box to pull away from its anchoring. Even if the service wires are not broken or disconnected by the resulting tension, sections of the protective conduit around the service wires are frequently pulled apart or away from each other. In some cases there can be a breaking away of portions of the building structure to which the service extends. Problems such as these must be remedied.
