Which method is commonly used for inspecting existing drainage systems?

Camera inspections are widely recognized as a standard and effective method for inspecting existing drainage systems. This technique involves the use of specially designed cameras that can be inserted into pipes to capture visual images of the interior surfaces. These cameras provide real-time footage, allowing drainlayers to assess the condition of the pipes, identify blockages, cracks, or other issues, and evaluate overall system functionality without requiring extensive excavation or disruption.

The ability to visually inspect the drainage system in this way significantly improves diagnostic accuracy and efficiency. It allows for targeted repairs based on direct observation, which can save time and resources during maintenance and restoration work. This method's non-invasive nature also preserves the integrity of the surrounding area, making it a preferred choice for many drainlayer professionals.
