How a CCTV Drain Survey helped uncover the cause of subsidence

At Drain 2 Drain, we specialise in CCTV drain surveys in Derby, helping property developers and homeowners diagnose hidden drainage issues before they escalate. Recently, a property developer approached us with concerns about subsidence affecting one of their new builds. Using our advanced CCTV technology, we conducted a thorough drain inspection—and what we uncovered was the key to resolving the problem before it caused further structural damage.

The Problem: Unexplained Subsidence on a Development Site

The developer noticed early signs of subsidence, including:

• Small cracks appearing in walls
• Uneven flooring
• Doors and windows not closing properly

While there were no obvious drainage issues, we suspected that an underground drainage fault could be contributing to soil movement beneath the foundations. A CCTV drain survey was the best way to confirm this without unnecessary excavation.

How Our CCTV Drain Survey in Derby Identified the Issue

We deployed our state-of-the-art CCTV drain cameras to inspect the entire underground drainage system. The results revealed a significant problem:

• A cracked and displaced drain pipe was leaking water beneath the foundation.
• This ongoing leakage had gradually softened the soil, causing ground instability.
• As a result, the foundation of the property had started to shift, leading to the visible signs of subsidence.

Without this advanced inspection, the issue could have gone undetected for much longer, potentially leading to expensive foundation repairs down the line.

Our Solution: Repairing the Drainage System to Stabilise the Foundation

Once we identified the cause, our team quickly formulated a plan to fix the problem:

1. Drain Repairs: We excavated the affected area and replaced the damaged drain pipes with durable, high-quality replacements.
2. Drain Relining: To prevent future leaks, we applied a trenchless drain relining technique to reinforce the surrounding pipes.
3. Soil Stabilisation: With the leaks sealed, the foundation could gradually settle back into place without further disturbance.
4. Final CCTV Survey: After the repairs, we conducted a second CCTV drain survey to confirm that the drainage system was fully functional and no further leaks were present.

The Results: A Secure, Stable Foundation for the Property

Thanks to our CCTV drain survey expertise, the property developer was able to resolve the subsidence issue before it worsened. By fixing the underlying drainage problem, we helped protect the structural integrity of the building and saved the developer from costly remedial work in the future.
