A borescope survey is a non-destructive inspection method that uses a small, high-resolution camera (a borescope or endoscope) on a flexible or rigid tube to visually examine concealed and otherwise inaccessible areas within a structure or machine. The process is minimally invasive and involves:
Creating Access: A small hole, typically around 10mm in diameter, is drilled into the area of interest (e.g., an external wall’s mortar joint, a pipe, or an engine access port). Borescope surveys facilitate this.
Insertion: A specialist camera probe with an integrated light source is inserted into the void.
Inspection and Recording: The camera transmits live video and images to an external display, allowing a professional to assess the internal condition. High-quality photos and videos are often recorded for later analysis and reporting. Borescope surveys facilitate this
Making Good: After the inspection is complete, the small access holes are sealed with appropriate sealant or mortar.
Common Applications
Borescope surveys are used across many industries where internal inspection without major disassembly is necessary:
-
Building & Construction: This is a primary use, often referred to as a cavity wall inspection. It helps determine wall construction, check for insulation presence and condition (e.g., damp or slumped insulation), identify the cause of persistent damp and mould, assess wall ties for corrosion, and locate hidden pipes or pest infestations.
-
Automotive/Aerospace: Mechanics use borescopes to inspect the internal components of engines, turbines, and machinery for wear, cracks, or damage without tearing down the entire system, saving significant time and cost.
-
Plumbing & Drainage: Flexible cameras can navigate pipework to locate leaks, blockages, or structural damage in drainage systems or internal plumbing.
-
Manufacturing: They are used for quality control to inspect the interior surfaces of cast or machined parts for defects.
Benefits
-
Non-Destructive: It avoids the need for extensive, costly, and time-consuming dismantling or demolition of structures or machinery.
-
Accurate Diagnosis: Provides clear visual evidence of hidden issues, allowing for targeted and effective repairs.
-
Cost-Effective: Early detection of potential problems can prevent minor issues from escalating into major, expensive failures.
-
Detailed Documentation: The captured images and videos can be included in detailed reports for insurance claims, maintenance planning, or regulatory compliance.
