Tree Roots Invading Your Pipes? What Brisbane Homeowners Should Know

Root intrusion is one of the most common tree-related problems in Brisbane. Here's what's happening, which species are the worst offenders, and your options.

Which trees cause the most pipe damage in Brisbane

Ficus (fig) species are the worst offenders — their root systems are aggressive and actively seek water sources. Camphor laurel, brush box, and some eucalypt species also cause problems. Native fig species planted in suburban gardens before their growth habit was well understood cause significant infrastructure damage in Brisbane.

How roots find pipes

Tree roots don't break into pipes that are perfectly sealed. They enter through existing cracks, joins, or degraded joints. Once inside, they grow rapidly toward the water and nutrient source. An old clay pipe with aging joins is much more vulnerable than a modern PVC run.

Signs you have root intrusion

• Slow-draining sinks or toilets in multiple locations simultaneously
• Gurgling sounds from drain fixtures
• Sewage odours near garden areas
• Wet patches in the lawn above the sewer line
• A CCTV drain inspection showing root intrusion

Your options

The plumber handles the pipe repair. We handle the tree. Removing the tree doesn't automatically fix a root-invaded pipe — the roots already inside continue to cause problems until the pipe is repaired or replaced. Tree removal prevents future growth. For trees you want to keep, regular hydro-jetting and liner repairs can manage the situation without removal.
