Repairing drains in a city built on sand
Perth’s drainage failures have a pattern. The pre-1980 suburbs run earthenware pipes whose rubber-less joints were always going to leak eventually; the coastal plain’s deep sand lets pipes settle, offset and belly; and wherever a joint weeps, the metro area’s magnificent trees send roots to the water. Clearing restores flow. Only repair removes the fault.
Our repair philosophy is simple and occasionally costs us revenue: the camera decides, and no-dig comes first. Every repair we quote begins with recorded CCTV footage of the actual defect, located to the centimetre. And wherever the pipe can take a liner, we reline instead of digging — because a repair that doesn’t destroy your paving, lawn or limestone driveway is simply a better product at a better price.
No-dig relining: the new pipe inside your old one
Pipe relining saturates a felt or fibreglass liner with structural resin, positions it across the damaged section (or the full line), and cures it hard against the host pipe wall. The result is effectively a new pipe: smooth-bored, continuous, and — critically for Perth — jointless. Roots that spent decades exploiting the old earthenware joints have no way into a cured liner.
Two flavours cover most jobs:
Sectional patches repair a single failed joint or crack — the classic root-entry point that keeps blocking a sewer line in Melville or Duncraig. An hour or two of work, no excavation, and that joint is permanently closed to roots.
Full-length relining rebuilds a line that’s tired end-to-end — the right call when the camera shows damage at joint after joint, and dramatically cheaper than excavating a whole run under an established garden.
Relining especially earns its keep where digging hurts most: the limestone ground of coastal pockets like Watermans Bay, established landscaping, driveways, and hills blocks in Kalamunda where the pipe run disappears under granite country.
When we do dig — and how
Some failures are beyond lining: a pipe crushed flat under a driveway, a fully collapsed section, a junction that has dropped away. Then we excavate — but surgically. The locator has already marked position and depth, so the excavation is one clean hole over one confirmed fault. You approve the scope and the surface reinstatement plan before a shovel moves, and the post-repair camera pass goes in your records with the warranty.
What we won’t do is quote “dig it all up” because it’s easier to price. If you’ve received a quote like that, bring it to us with or without footage — the camera survey that confirms or dismantles it costs a few hundred dollars and takes an hour.
Fix it once, on evidence
If a drain keeps blocking, smells persist, or ground is sinking along a pipe run, the fault is findable and fixable — once, properly, on camera evidence. Get honest repair options anywhere in the Perth metro area.
