Underground Surveying & Manhole Benching – The Key To Drain Blocking

Did you know that drainage inspections are an essential part of maintaining sewer systems? Well, the ideal way to maintain a healthy drainage system is through prevention. And, undertaking a professional drain survey can help prevent sewer problems from worsening. Using specialist underground surveying is, therefore, important to examine and inspect your drains.

Manholes are an indispensable part of drains, giving clear access points to the underground pipes and allowing surveys to be carried out above the ground to inspect the condition of pipes. Sewer surveys are used for assessing the situation of a drainage system through the utilisation of a closed-circuit television camera. Once they gain access to your drains, the engineer will insert a CCTV camera inside to capture real-time drain inspection footage. After assessing the footage, they can produce a drain camera survey report with recommendations.

Here’s an insight into all you need to know about manhole bench and drain surveys.

Manhole Benching: What Is It?

Benching in manholes refers to the pathway made out of cement mortar for directing the waste in a certain course and preventing the splash of waste, which sequentially damages the manhole. Its main purpose is to direct flow back into the channel if a backup occurs in the manhole owing to blockage.
