Permanent Drain Repairs That Last Decades
Persistent blockages, foul odours, wet patches in your yard, and subsidence often indicate damaged drains requiring structural repair rather than simple clearing. Collapsed pipes, tree root damage, corrosion, and ground movement create drainage failures that blockage clearing alone cannot fix. Panther Plumbing Group's licensed drainage specialists diagnose drain damage accurately using CCTV inspection and deliver permanent repairs tailored to your situation—from compact sectional excavations to full pipe replacements and trenchless relining.

Trenchless & Traditional Options

Concrete, pavers, asphalt, turf, and landscaping restored professionally. Comprehensive warranties on workmanship and materials. Compliance certificates provided.
Common Drain Damage Requiring Repair
Understanding drain damage helps determine the right repair method
Collapsed Pipe Sections
StructuralAgeing terracotta, earthenware, and concrete pipes collapse due to ground movement, corrosion, or heavy traffic loads above. Collapsed sections require excavation and replacement—clearing provides only temporary relief.
Tree Root Intrusion
ProgressiveSydney trees send aggressive roots through drain joints seeking moisture. Roots create dense masses that crack pipes, displace sections, and eventually cause collapse. Requires cutting and often relining or replacement.
Offset or Misaligned Joints
LeakingGround settlement shifts drain sections, creating misaligned joints that leak and catch debris. Offset pipes allow soil infiltration, tree root entry, and gradual drainage failure requiring realignment or replacement.
Corroded or Cracked Pipes
DeteriorationCorrosion from soil conditions, age, or chemical exposure creates cracks and holes in metal and concrete pipes. Cracked sections leak wastewater into surrounding soil, contaminating property and requiring replacement.
Incorrect Gradient or Fall
InstallationImproperly installed drains with insufficient gradient allow waste to accumulate rather than flow. Incorrect fall creates recurring blockages that clearing cannot fix—pipes must be reinstalled to correct specifications.
Bellied or Sagging Pipes
SubsidenceGround subsidence creates low spots in drain runs where waste and water collect. Bellied pipes develop persistent blockages and eventually fail completely. Excavation and replacement restore proper drainage.
When You Need Drain Repairs
These signs indicate structural damage requiring professional repair
Recurring Drain Blockages
Drains that block repeatedly despite professional clearing indicate underlying structural damage. Tree roots, collapsed sections, or bellied pipes require repair rather than repeated clearing.
Wet Patches or Subsidence in Yard
Unexplained soggy areas, lush grass patches, or ground sinking indicate leaking underground drains. Wastewater escaping through damaged pipes creates environmental and structural hazards requiring urgent repair.
Persistent Sewage Odours
Foul smells that persist after drain clearing indicate cracked or broken pipes leaking sewer gases. Underground leaks require CCTV inspection to locate and professional repair to seal.
Multiple Drains Affected Simultaneously
When all drains slow or back up together, damage is in your main sewer line. Main line collapse, severe root intrusion, or structural failure requires comprehensive inspection and major repair.
Visible Ground Movement or Cracks
Cracks in paving, driveways, or building foundations near drain runs indicate serious subsidence from leaking underground pipes. Soil erosion threatens property stability and requires immediate investigation.
Unusual Garden Growth Patterns
Extra lush grass, thriving plants, or odd growth patterns above drain lines indicate underground leaks fertilising vegetation. Wastewater leaks contaminate soil and create health hazards requiring urgent repair.
How We Repair Damaged Drains
Professional diagnosis and permanent repair solutions
CCTV Inspection & Precise Location
High-definition drain cameras navigate your entire drainage system documenting all damage. Sonde locating technology pinpoints exact damage depth and position for targeted repairs. You receive detailed video evidence and comprehensive reports.
Damage Assessment & Repair Options
We analyse CCTV footage to determine damage severity and recommend repair methods—trenchless relining for cracks and root damage, patching for localised holes, or excavation for collapsed sections. Multiple options presented with transparent pricing.
Council Approvals & Traffic Management
For excavations affecting roads or footpaths, we arrange council permits and traffic management. Property owners receive detailed work plans including excavation location, depth, duration, and reinstatement specifications.
Excavation or Trenchless Repair
Experienced crews execute repairs using appropriate methods. Excavations are kept minimal and safe with shoring if required. Trenchless relining or patching provides no-dig solutions where suitable. All work meets Australian Standards.
Pipe Replacement & Installation
Damaged sections replaced with modern PVC, HDPE, or vitrified clay pipes to specifications. New pipes installed at correct gradient with proper bedding and backfill. Joints sealed to prevent future root intrusion.
Testing, Reinstatement & Warranty
Post-repair CCTV confirms flowing drains and quality installation. Excavations filled, compacted, and surfaces reinstated—concrete, pavers, asphalt, or turf restored. Comprehensive warranties provided on all workmanship and materials.
Tailored Drain Repair Solutions
Right method for every damage type
Sectional Excavation & Replacement
Targeted excavations replace only damaged pipe sections, minimising disruption and cost. Modern materials like PVC ensure decades of reliable drainage. Surfaces professionally reinstated to match existing finishes.
Trenchless Pipe Relining
No-dig technology creates seamless epoxy liners inside damaged pipes. Suitable for cracks, root damage, and corrosion without excavation. Relined pipes perform like new for 50+ years with minimal property disturbance.
Pipe Patching & Point Repairs
Localised damage like cracks or small holes receive targeted epoxy patches. Installed through existing access points without digging. Cost-effective repairs for minor damage caught early through CCTV inspection.
Complete Drain Replacement
Extensively damaged or undersized drains require full replacement. New systems designed to specifications with proper gradient, materials, and capacity. Ideal for ageing properties or drainage upgrades.
Root Cutting & Prevention
Mechanical root cutting removes intrusions before relining creates root-proof barriers. Chemical treatments prevent regrowth. Combined approach provides long-term protection against Sydney's aggressive tree roots.
Minimal Disruption Guaranteed
