The one-call service that notifies utility owners so buried lines can be marked before digging begins.
Tennessee 811 describes itself as the state's one-call center, which notifies member utility owners when someone plans to dig so underground lines can be marked. Retaining wall projects involve excavation for footings, base material, drains and sometimes anchors, so calling before digging is an essential first step. Homeowners and contractors in Nashville use the service to reduce the risk of hitting gas, electric, water, sewer and communication lines.
We are an independent company and are not part of Tennessee 811. We request locates for our projects as part of our process and plan walls around the marks. Private lines such as irrigation, lighting and septic are often not marked by the service, so we ask you about them. The official site explains how to submit a request and how long to wait, and we are happy to walk you through the steps.

No. We are an independent retaining wall company and are not part of Tennessee 811. We explain what it publishes in plain language and help you apply it to your own project.
