When Mosman homeowner Jocelyn Hamilton noticed stormwater flooding at the rear of her property during heavy rainfall, she knew it needed urgent attention. Located at 2 Cyprian St, Mosman NSW, the home sits on a sloping block backing onto the beachfront – a stunning location but one with complex drainage challenges. She contacted Pearla Plumbing for professional help after noticing water pooling dangerously near her pool area.
The Problem: Dangerous Flooding and a Hidden Blockage
Upon arrival, our team inspected the property and located a large stormwater pit at the bottom of a staircase on the left-hand side of the house. The pit lid had shifted due to overflowing stormwater, creating a safety hazard and increasing the risk of property damage.
The pipe ran under sensitive areas close to the pool structure
Excavation was not a safe option due to the location and risk of structural damage. A trenchless pipe repair solution was the best approach.
The Solution: Pipe Relining to Repair Without Digging
To permanently restore stormwater flow, Pearla Plumbing recommended pipe relining — a proven no-dig method that repairs damaged pipes internally.
What is Pipe Relining?
Pipe relining involves inserting a structural liner into the damaged section of pipe. The liner is soaked in epoxy resin and cured in place to create a new pipe within the old pipe. This method:
Prevents future root intrusion
Eliminates the need for excavation
Strengthens old or cracked pipes
Restores full water flow
Is long-lasting and cost-effective
Pipe relining is ideal for properties in coastal suburbs like Mosman and the Northern Beaches, where mature trees and sandy soil often cause repeated drainage failures.
Step-by-Step Work Completed
Our licensed plumbers and relining specialists carried out the following:
Site setup and safety preparation High-pressure cleaning of the stormwater line Cutting and clearing of heavy tree roots CCTV camera inspection to map pipe damage Installation of four structural liner patches Final quality inspection to confirm full restoration of flow
The relining was installed between pit 2 and pit 3, targeting the damaged sections of pipe previously blocked by roots. Because relining is trenchless, there was no need to disturb landscaping, stairs, or the pool foundation—saving the homeowner thousands in property repair costs.
The Result
The job was completed within a day, with minimal disruption to the homeowner. The relined stormwater system now flows correctly, preventing future flooding.
