Four common causes of a collapsed drain
In the UK, collapsed drains can lead to sewage problems, property damage, and environmental contamination. Several factors can contribute to drain collapse, so it is important to identify these and have them fixed as soon as possible.
1. Age and deterioration can be a factor
Many drainage systems in the UK are old and made of materials such as clay, concrete, or cast iron, which can deteriorate over time. This is due to exposure to moisture, soil movement, and chemical reactions.
2. Tree roots intruding into the pipes can cause problems
Tree roots are naturally drawn to sources of water and can infiltrate drains through small cracks or joints in the pipes. As roots grow and expand, they can put pressure on the pipe walls, causing them to crack or even collapse. According to the BBC, a collapsed sewer in Reading last year caused disruption for residents and businesses.
3. Ground movement such as subsidence can put pressure on pipes
Subsidence, soil erosion, and ground shifting due to geological factors or construction in the area can put pressure on underground drainage pipes, leading to collapse. A CCTV drain survey is a method used to assess the condition of underground drainage systems using closed-circuit television (CCTV) technology. A CCTV drain survey Loughborough can identify any defects or abnormalities in the drainage system.

4. Heavy traffic or large loads can cause collapse
Drains located beneath roads, driveways, or other areas used by heavy traffic or loads are susceptible to damage from the weight and pressure of vehicles passing over them. Over time, this can cause the pipes to crack, break, or even collapse. Collapsed drains pose serious risks to property, as they can result in sewage leaks, flooding, foul odours, and structural damage.
If you suspect a collapsed drain on your business grounds or at your home, or if you see signs such as slow drainage, bad smells, or sinkholes, it is essential to seek professional assistance from a drainage contractor.
