Blocked and damaged drainage systems cause havoc for businesses and domestic properties. CCTV drain surveys are a great way to identify the root of issues without causing major disruptions. This type of drain inspection will provide clear footage of what’s happening in the system to see if something can be done to prevent further problems.
Here are some of the most common issues identified during a drainage health check.
Tree roots in drains
One of the strangest but most common blocked drain causes is tree roots! They seek out areas of moisture in the ground, growing through tiny cracks or system joints if they want to get hold of the water available in the drain network. Once inside, they expand more, causing blockages, pipe damage and water flow restrictions. Tree root jetting and relining are good solutions for this issue.
Foul smells from drains
One of the top drainage survey benefits is finding out the causes of unpleasant odours. This usually indicates a blockage, which CCTV can pick up by threading a tiny camera through the pipes. The smell usually comes from trapped debris, stagnant water, grease, food waste or decaying organic matter.
Cracked drain pipes
Drain survey technology can pick up on cracks in the system caused by ground movement, ageing materials or external pressures. Unfortunately, this can lead to water seeping into the surrounding soil, causing further surface water issues, erosion and structural weaknesses. Drainage system repairs can prevent this.
Water pooling problems
Worried about standing or pooling water on your patio, garden or driveway? Excessive water flow from drain covers may be the cause. A CCTV drain survey will find the reason for poor drainage issues, such as misaligned pipes, blockages and collapsed drain sections.
Collapsed drain structures
The drainage inspection process can also identify collapsed pipes within older systems or those exposed to heavy usage. This may be the cause of back-ups in wastewater and flooding. A CCTV drain survey can easily find the collapsed section to be excavated and replaced.
Soil erosion near drains
One of the most common drainage problem symptoms is soil erosion, leading to sinkholes, unstable ground and problems with property foundations. This shows drainage survey importance, allowing for prompt identification of leaks and repairs to prevent building and landscape damage.
Damaged drain covers
A key part of drainage system maintenance is checking drain covers. A broken or missing cover is a major safety hazard, causing debris, animals or people to fall into the system. Exposed drains are also exposed to dirt and blockages.
Drainage pump failures
Some properties depend on the use of drainage pumps to move wastewater away from low-lying spaces. However, if these pumps fail, flooding and water damage can occur. Drainage report findings can assess the performance of drain pumps and identify mechanical faults requiring maintenance.
Drainage pipe corrosion
Pipes made from certain metals may experience corrosion over time, affecting the system structure. This can lead to drain leaks identification and collapses. Drainage system upgrades should be completed, such as relining or pipe replacement work.
