Drain Damage? Repair It Properly.
From damaged underground drainage to recurring problems that need more than another unblock, AJS investigates the cause and helps determine the appropriate drain repair solution.
Fix the cause.
Not just the symptom.
A drainage problem that repeatedly returns can sometimes indicate damage or another defect within the underground pipework.
Before deciding how a drain should be repaired, it is important to understand what has gone wrong, where the problem is located and the condition of the surrounding drainage system.
AJS combines drainage investigation with repair capability, allowing the problem to be assessed before an appropriate repair method is considered.

When is a blockage
more than a blockage?
Not every blocked drain is damaged. But when drainage problems keep returning or there are signs of an underlying defect, further investigation may be needed.
Recurring Blockages
A drain that repeatedly blocks after clearing may need investigation to establish why the problem keeps returning.
Visible Damage
CCTV inspection may reveal cracks, displaced sections or other visible defects within accessible drainage.
Poor Drainage
Persistent drainage problems can indicate that the pipework needs more than routine cleaning or clearing.
Suspected Defect
Where damage is suspected, investigation can help establish the location and nature of the problem.

Diagnose first.
Repair second.
Underground drainage is largely hidden from view. Excavating simply to discover what might be wrong is not always the first step.
Where appropriate, CCTV drain inspection can help examine the internal condition of the pipework and identify visible defects before repair work is planned.
This provides better information about the problem and helps determine which repair approach may be suitable.
It depends on the drainage problem. When the location, cause or extent of a suspected defect is unclear, CCTV inspection can provide useful information before the appropriate repair method is selected.
Can a damaged drain
be repaired without digging?
In suitable circumstances, yes. Some damaged drainage pipework may be suitable for specialist no-dig repair or lining techniques.
Rather than exposing a long section of underground pipe, a suitable repair system can sometimes be installed internally. Whether this approach is appropriate depends on the defect, pipe condition, access and other site factors.
Find it.
Fix it properly.
Understand The Problem
We start with the drainage symptoms, history and what has already been done.
Investigate
Where necessary, the drainage system can be inspected to help identify the location and nature of the defect.
Choose The Repair
The findings help determine whether conventional repair, lining or another suitable approach should be considered.
Repair & Restore
The objective is to address the identified drainage defect and restore the system appropriately.
One drainage problem.
A logical next step.
A drainage problem can begin with a simple blockage. If clearing does not solve the underlying issue, investigation can help identify what is happening before repair work is considered.
Restore the flow and clear the immediate drainage obstruction.

Quick answers.
How do I know if my drain needs repairing?
Repeated drainage problems do not automatically mean that a drain is damaged. If an underlying defect is suspected, inspection can help establish the condition of the pipework before repair is recommended.
Can a damaged drain be repaired without digging it up?
Some damaged drains may be suitable for specialist no-dig repair or lining. Suitability depends on the defect, pipe condition, access and other site factors.
What is drain lining?
Drain lining is a specialist repair approach in which a suitable lining system is installed within existing pipework. It may provide a repair option for certain defects without exposing the entire pipe.
Do I need a CCTV survey before drain repair?
Not in every situation. Where the cause, location or extent of a drainage defect is unclear, CCTV inspection can provide useful information before deciding on the appropriate repair.
Why does my drain keep blocking after it has been cleared?
A recurring blockage may have an underlying cause. Further investigation can help establish whether there is a visible defect or another condition contributing to the problem.
Do all damaged drains need excavation?
No. The repair method depends on the individual drainage defect and pipe condition. Some problems may be suitable for no-dig techniques, while others may require conventional excavation and repair.
