Common faults Common Pipe Relining Problems We Fix
Most of our local reline work traces back to a short list of recurring drainage faults across the planned 1985-onwards estate stock in the area, where four decades of established trees, reactive hillside ground movement, and intense Adelaide winter downpours have steadily worked on the underlying PVC drainage. These are the problems trenchless repair handles best on the estate-era north-eastern Adelaide blocks:
01
Tree-root intrusion through offset PVC joints
Forty years of established garden trees along the curved estate streets routinely send fine roots into the original PVC drainage runs, and a trenchless liner seals the joints so the same roots cannot find their way back in.
02
Builder-shortcut fittings failing three decades on
The rapid 1985-onwards project-builder rollout left many homes with shortcut waste and water fittings from the original construction, and a cured-in-place liner rebuilds the worst residential runs into one continuous inner wall.
03
Partially collapsed sections under hillside runs
Decades of reactive ground movement on graded blocks above the Cobbler Creek catchment leave sagging or partly collapsed sections in residential drains, and a properly cured liner handles both fracture and minor inward collapse without digging up sloped yards.
04
Recurring blockages in the same run
A drain that blocks every few months after clearing usually has a structural defect feeding the issue, and relining fixes the underlying cause rather than chasing the symptom callout after callout.
05
Stormwater pits overloading on heavy winter downpours
Original estate-era stormwater pits and downpipes routinely overload during intense Adelaide winter rain, and relining the stormwater run between pit and street main restores full capacity ahead of the next storm.
