Tree Roots and Brisbane Swimming Pools: What to Know

Pool damage from tree roots is a common and expensive problem in Brisbane. Prevention is much cheaper than repair.

Which trees cause pool problems

Ficus species (fig trees) are the main offender — their root systems actively seek water and can work their way into pool shell cracks or around plumbing connections. Large eucalypts, camphor laurel, and poincianas with extensive root systems also cause problems near pools.

How pool damage happens

Root intrusion typically exploits existing weaknesses — hairline cracks in concrete shells, rubber seals around fittings, or flexible plumbing joints. Once inside, roots grow toward the water and nutrient source, widening existing cracks or displacing surrounding soil.

Minimum safe distance from a pool

As a general guide: trees up to 5m height should be planted at least 3m from a pool; trees 5–10m at least 5m; larger trees at least 8–10m. These are minimums — species with aggressive root systems should be planted further.

What to do if roots are near the pool

Have an arborist assess the tree and root system before the pool shows damage. Root barriers installed before roots reach the pool shell can redirect growth. If roots have already reached plumbing: remove the tree, treat the stump, and have the pool plumbing inspected.
