Comprehensive Drain Investigation Services
Our drain investigation service is designed to effectively identify and locate issues within drainage systems. We utilise various methods, including dye tests, smoke tests, pressure tests, and CCTV camera surveys, to pinpoint problems accurately. These techniques allow us to assess the condition of your drains and determine the most optimal course of action for repairs. Additionally, we offer S.O.N.D. tracing to map out drainage paths and provide detailed manhole condition reports and invert levels. By employing these advanced investigation methods, we ensure that your drainage systems are functioning optimally and free from hidden issues.

Effective Dye Testing For Drainage Systems
Dye testing is a straightforward yet effective method for tracing the flow of drains and identifying potential leaks. This visual technique involves injecting a harmless dye into the drainage system, allowing us to confirm whether a drain run terminates where suspected or to identify its outfall among several possibilities. By observing the movement of the dye, we can accurately pinpoint any issues within the system. This method is particularly useful in assessing pipe integrity and ensuring that your drainage operates as intended. Our expertise in dye testing ensures we can provide reliable insights into your drainage system's condition.


Advanced S.O.N.D. Tracing Techniques
S.O.N.D. tracing is an innovative method to accurately locate and map drainage systems. This technique operates similarly to an echo sounder or metal detector, where a probe (transducer) is inserted into the drain. At the same time, a surface unit (receiver) follows the signal emitted by the probe. This allows us to precisely trace the drain path, making it easier to identify defects or blockages within the system. By utilising S.O.N.D. equipment, we enhance our ability to thoroughly assess your drainage infrastructure, ensuring necessary repairs can be carried out efficiently and effectively.
Smoke Testing And Water Pressure Testing
Smoke testing and water pressure testing are essential for identifying structural faults in drainage systems. Smoke testing involves inserting drain bungs into the system and applying non-toxic smoke; if there are any cracks or breaks in the pipes, the smoke will escape, revealing the location of the fault. For below-ground drainage systems, water pressure testing is conducted by filling sections of the drain with water and measuring any loss over time. This method can also incorporate dye to help locate leaks more effectively. Both techniques are crucial for maintaining the integrity of your drainage system and facilitating timely repairs when necessary.
