A CCTV drain survey involves inserting a small, high-resolution camera into your drainage system to inspect the interior of the pipes in real time. This visual assessment helps identify blockages, cracks, leaks, and other structural issues that might not be apparent from the surface. By pinpointing the exact location and nature of any problem, engineers can recommend targeted solutions, potentially saving you from unnecessary excavation or costly guesswork. CCTV surveys are especially useful when purchasing a new property, as they reveal the condition of the existing drainage network. They can also be employed after repeated blockages to determine underlying causes, such as collapsed sections or root intrusions. The footage is typically recorded, providing a valuable reference for any required repairs. Overall, CCTV drain surveys offer a clear, efficient, and minimally invasive way to diagnose drainage problems, ensuring issues are addressed quickly and accurately.
