Professional Open-Trench Drainage Solutions

When drains collapse, crack, or become overrun with tree roots, sometimes the only effective fix is to expose the line and replace it. Open-trench excavation remains the most reliable way to repair severely damaged stormwater and sewer pipes, restoring full flow and long-term stability to your property.

At CS Plumbing & Drainage Services, we provide licensed excavation and repair services for homes, businesses, and strata-managed properties across Wollongong and the Illawarra.
With over 35 years of drainage expertise, we combine proven methods with modern equipment to repair pipework safely and with minimal disruption.

Our Drain Excavation and Repair Services Include

  • Full Open-Trench Excavation
    We carefully expose damaged pipes using precision excavation methods, protecting surrounding structures and landscaping wherever possible.
  • Pipe Replacement
    If pipes are collapsed, undersized, or root-invaded beyond repair, we install heavy-duty replacement pipework that meets today’s flow standards.
  • Pipe Relining and Partial Repairs
    Not all jobs require full excavation. We offer hybrid solutions, combining trenching with trenchless relining for the most cost-effective outcome.
  • Root Removal and Prevention
    Tree root intrusion is a leading cause of drain collapse. We remove roots, repair damage, and install preventative measures to reduce repeat invasions.
  • Sewer and Stormwater Excavation
    From residential sewer mains to commercial stormwater infrastructure, we manage excavation projects of all sizes with the correct approvals and compliance.

When Do You Need Drain Excavation?

  • Repeated blockages despite jetting and relining
  • Cracked or collapsed pipes on CCTV inspection
  • Ground movement or subsidence affecting drains
  • Ongoing tree root invasion in older clay pipes
  • Poorly laid or undersized original pipework

If you’ve been dealing with recurring blockages or unexplained drainage issues, excavation may be the permanent solution.
