Yes, absolutely. Before starting any concrete demolition or excavation work, it's crucial to contact your local utility notification center (811 in the United States or the equivalent in other countries). They will notify relevant utility companies, who will then send locators to mark the approximate locations of underground utility lines on your property. This essential step helps prevent accidental damage to buried utilities, such as gas lines, electrical cables, water pipes, and communication lines. Striking a buried utility line can be extremely dangerous, leading to explosions, fires, electrocution, and service disruptions. It can also result in costly repairs and fines. Calling 811 or your local utility notification center is a free service and a crucial safety precaution before any demolition or excavation project.
