Tree Roots: The #1 Cause of Blocked Sewers in Brisbane
Tree roots are the number one cause of blocked sewer drains in Brisbane. Our warm climate and clay soils create perfect conditions for aggressive root growth. Once roots enter a sewer pipe, they can grow rapidly and cause complete blockages.
How Tree Roots Enter Sewer Pipes
Tree roots are attracted to the moisture and nutrients in sewer pipes. They can enter through:
- Cracked or broken pipe sections
- Deteriorated pipe joints
- Small gaps in clay pipe connections
- Broken inspection openings
Signs of Tree Root Blockages
- Recurring blocked drains
- Gurgling sounds from toilets and drains
- Slow draining fixtures
- Bad smells from drains
- Wet patches in the yard
- Sewer overflow during heavy rain
How We Remove Tree Roots
At DrainSpy Brisbane, we use specialised equipment to remove tree roots:
1. CCTV Drain Inspection
First, we use a CCTV drain camera to identify the exact location and extent of the tree root intrusion. This gives us a clear picture of the problem.
2. High-Pressure Water Jetting
We use high-pressure water jetting with specialised root-cutting nozzles to cut through and flush away tree roots.
3. Mechanical Root Cutting
For severe root intrusions, we use mechanical root cutting equipment that physically cuts through the roots.
4. Pipe Relining
After removing the roots, we often recommend pipe relining to seal the pipe and prevent roots from re-entering. This creates a new, seamless pipe inside the old one.
Preventing Tree Root Re-growth
Tree roots will grow back if the entry point isn't sealed. The most effective long-term solution is pipe relining, which creates a completely new pipe surface that roots cannot penetrate.
