CCTV Drainage Surveys
Detailed Inspection of Drainage Systems Using Advanced Camera Technology
CCTV drainage surveys are a key method of assessing the condition and performance of underground drainage systems. Chelmer provide a comprehensive CCTV survey service using modern inspection equipment, allowing detailed visual assessment of pipework without the need for extensive excavation.
These surveys are widely used as part of site investigations and subsidence assessments, where understanding the condition of drainage infrastructure is essential. By capturing high-quality footage from within the system, Chelmer are able to identify defects accurately and provide clear evidence to support further investigation or remedial works.
Purpose of CCTV Drainage Surveys
The primary purpose of a CCTV drainage survey is to inspect the internal condition of drainage systems and identify any defects that may be present. These can include cracks, fractures, displaced joints, blockages and root ingress, all of which can affect the performance of the system.
In subsidence investigations, CCTV surveys play a particularly important role in determining whether drainage defects may be contributing to ground movement. Leaking or damaged pipes can lead to localised changes in ground conditions, making accurate inspection essential.
By identifying issues early, CCTV surveys help prevent further deterioration and support effective planning of repairs or maintenance.
Survey Methodology and Equipment
Chelmer utilise industry-recognised CCTV systems to carry out drainage inspections, ensuring that surveys are completed to a high standard. Cameras are introduced into the drainage system and guided through the pipework, capturing continuous footage of the internal condition.
The equipment used allows for clear and detailed imaging, even within complex or difficult to access systems. This ensures that defects can be identified accurately and that the condition of the drainage network is fully understood.
Surveys are carried out by experienced operatives who are able to interpret the footage and identify issues that may not be immediately obvious, providing valuable insight into the condition of the system.
Applications in Site Investigation and Subsidence
CCTV drainage surveys are commonly used alongside other site investigation methods, such as trial pits and boreholes, to provide a complete understanding of ground conditions. By assessing both the ground and the drainage infrastructure, Chelmer are able to identify potential interactions between the two.
In subsidence cases, CCTV surveys help determine whether defective drainage is a contributing factor or whether damage has occurred as a result of ground movement. This distinction is important when assessing the cause of the issue and planning appropriate remedial measures.
The information obtained from CCTV surveys is often critical in supporting the overall investigation and ensuring that all relevant factors are considered.
Integration with Drainage Investigation Services
CCTV surveys form part of Chelmer’s wider drainage investigation offering, which may also include hydraulic testing, leak detection and repair works. By combining these services, Chelmer are able to provide a complete assessment of drainage systems and their impact on the site.
Where defects are identified, further investigation or repair works can be carried out as required, ensuring that issues are addressed efficiently. This integrated approach reduces the need for multiple contractors and helps streamline the overall process.
Reporting and Supporting Decision-Making
All findings from CCTV drainage surveys are recorded and incorporated into Chelmer’s reporting process. This includes detailed observations of the drainage system, along with any identified defects and their location.
The information provided allows engineers, developers and other stakeholders to make informed decisions regarding maintenance, repair or further investigation. By delivering clear and accurate reporting, Chelmer ensure that drainage conditions are fully understood and appropriately managed.
Through the use of advanced technology and experienced personnel, Chelmer’s CCTV drainage surveys provide a reliable and efficient method of assessing underground drainage systems across a wide range of projects.
