Root ingress happens when tree or plant roots enter drainage pipework through cracks, joints, displaced sections or damaged pipe materials. Once roots get into a drain, they can catch waste, restrict flow and cause repeated blockages.
Drain Division provides professional root ingress removal for domestic and commercial drainage systems. Our engineers can help clear root-related obstructions, inspect the pipework and advise whether the drain needs further repair to stop the same problem returning.
Root ingress is often discovered after repeated drain blockages, blocked outside drains or emergency drainage problems. A CCTV drain survey can help confirm where roots are entering the pipework.
Common Signs of Root Ingress
You may have roots growing into your drains if you notice:
Root ingress should not be ignored, especially if the blockage keeps returning after clearance.
Roots are naturally drawn to moisture and nutrients around drainage systems. They usually enter through an existing weakness in the pipe rather than pushing through a perfectly sound drain.
Common causes of root ingress include:
Once roots are inside the pipe, they can grow into a dense mass that traps tissue, grease, silt and other waste. This is why root ingress often leads to repeated drain unblocking rather than a one-off problem.
The right root ingress removal method depends on the amount of root growth, the access points available and the condition of the drain. In some cases, the immediate issue can be cleared, but the pipe defect will still need repair to stop roots returning.
Root ingress removal may include:
If roots have entered through cracks, open joints or a displaced pipe, further drain repairs or drain relining may be recommended.
Root ingress is usually connected to other drainage issues, particularly recurring blockages, damaged pipework and drains that need further inspection.

Drain Division provides root ingress removal and drainage services across many areas, including Aldershot, Basingstoke, Guildford, Reading, Southampton and Winchester.
Will roots grow back after they are removed from a drain?
Roots can grow back if the defect that allowed them into the pipe is still present. Cutting or clearing the roots may restore flow, but cracked pipework, open joints or displaced sections may need repair to stop the same issue returning.
Is root removal enough, or does the drain need repairing?
It depends on the condition of the pipe. If roots have entered through a small joint or crack, removal may solve the immediate blockage, but the drain may still need relining or repair. A CCTV drain survey can show whether clearance alone is enough.
Can drain jetting remove tree roots?
Drain jetting can help clear debris and some root-related obstructions, but heavy root growth may need cutting or mechanical clearance first. Jetting does not repair the point where the roots entered the pipe.
Do I need to remove the tree to stop root ingress?
Not always. The main issue is usually the damaged or open section of pipe that allowed roots in. Removing a tree may not solve the drainage problem if roots have already entered through a defect, and repair work may still be needed.
Will root killer fix roots in drains?
Root treatment products may help in some maintenance situations, but they should not be treated as a guaranteed repair. If the pipe is cracked, displaced or collapsing, chemical treatment will not fix the physical defect.
How do I know if roots are causing my blocked drain?
Recurring blockages, slow drainage, outside drains overflowing and problems near trees or hedges can all point to root ingress. The most reliable way to confirm the cause is usually a CCTV drain survey.
Can root ingress cause a collapsed drain?
Root ingress can worsen existing pipe damage and restrict the flow through the drain. If roots are allowed to grow inside weakened pipework, the risk of more serious damage, displacement or collapse can increase over time.
