Clearing Tree Root Blockages and Replacing Damaged Drainage Pipework
Our team attended a property in Cheltenham to investigate a blocked drain after signs of surcharge and poor drainage began appearing along the side of the property. In many cases, recurring drainage problems are caused by underlying pipe damage rather than a simple blockage alone.
For this project, Pure Plumbing Professionals carried out a full Blocked Drains investigation using CCTV Drain Inspection, followed by excavation and pipe replacement works to restore proper drainage flow.
The project involved locating tree root intrusion within the drainage system and replacing damaged sections of underground pipework to prevent future issues.
Why Tree Roots Cause Drainage Problems
Tree roots naturally seek out moisture, making underground drainage pipes a common target.
Roots often enter pipes through:
- Small gaps in joints
- Cracked pipe sections
- Weak points in ageing drainage systems
Once inside the pipe, roots continue to expand and trap debris, eventually restricting water flow and causing surcharge conditions.
Over time, this can lead to structural pipe damage and recurring blockages.
This type of issue is common in established areas like Cheltenham where mature trees and older drainage infrastructure are present.
Using CCTV Drain Inspection to Locate the Blockage
To determine the cause of the drainage issue, our team carried out a CCTV Drain Inspection.
This process involves feeding a specialised drain camera through the pipework to inspect the internal condition of the system in real time.
The inspection allowed our team to:
- Locate the exact position of the blockage
- Assess the condition of the pipework
- Identify areas affected by tree root intrusion
At Pure Plumbing Professionals, CCTV inspections are a key part of diagnosing Drainage Repairs, as they allow accurate planning before excavation begins.
Clearing the Drain with High-Pressure Water Jetting
After locating the blockage, high-pressure Drain Cleaning was carried out to restore flow through the system.
Water jetting is highly effective for removing:
- Tree roots
- Sludge and debris
- Organic build-up within the pipe
This process temporarily restored drainage performance and allowed further inspection of the damaged areas.
The affected sections were then marked for excavation and replacement.
Excavating the Damaged Drainage Sections
Once the damaged pipe sections were identified, excavation works were carried out in the affected areas.
The site conditions included soft clay and soil, requiring careful excavation to expose the drainage line safely.
Our team:
- Excavated the affected sections of drainage
- Exposed damaged PVC pipework
- Prepared the area for replacement works
Excavation is necessary when pipes are too damaged for internal repair methods.
Replacing the Damaged Pipework
After exposing the line, the damaged sections of PVC pipe were disconnected and removed.
Approximately 13 metres of new PVC drainage pipework was then installed to restore the system.
The new installation included:
- Correct alignment and fall for efficient drainage
- Secure connections into the existing system
- Durable modern pipework resistant to root intrusion
This type of Pipe Replacement improves long-term drainage reliability and reduces the likelihood of recurring blockages.
Installing Inspection Openings for Future Access
New upstream and downstream inspection openings were installed as part of the repair works.
Inspection openings allow:
- Easier future maintenance access
- Efficient clearing of potential blockages
- Future CCTV Drain Inspection without excavation
Including maintenance access points is an important part of professional Drainage Solutions.
Repairing the Downstream Drainage Connection
Additional repair works were completed near the property boundary and creek connection.
This section of the drainage system was reconnected to ensure:
- Correct downstream flow
- Reliable discharge into the existing stormwater system
- Proper integration with the surrounding drainage infrastructure
Concrete support was also provided to stabilise the pipework and protect the new connections.
Backfilling and Reinstatement
Once all pipework was installed and tested, the trenches were backfilled and ground levels reinstated.
Proper reinstatement helps:
- Protect the pipework below
- Restore ground stability
- Prevent future movement around the drainage system
All waste materials were removed and the site was left clean upon completion.
Testing and Commissioning the Drainage System
After repairs were completed, the drainage system was fully tested to confirm proper operation.
This included:
- Verifying correct drainage flow
- Checking all connections for performance
- Ensuring the repaired sections were operating effectively
Testing is a critical step in all professional Drainage Repairs to ensure the system is functioning correctly before completion.
What Most Homeowners Don’t Realise About Root Intrusion
Many homeowners assume clearing a blockage solves the issue permanently.
However, when roots have already damaged the pipe structure, the blockage is likely to return unless the damaged sections are repaired or replaced.
Tree roots can:
- Re-enter through damaged joints
- Continue expanding inside pipes
- Cause recurring surcharge problems over time
This is why both clearing and structural repair are often required together.
When Drain Excavation and Pipe Replacement Are Needed
Excavation and replacement are typically required when:
- Tree roots have damaged the pipe structure
- Drainage issues continue after clearing
- Pipes have cracked or shifted
- CCTV inspections reveal structural defects
Replacing damaged sections restores proper flow and improves long-term reliability.
