Project Overview
SEQ Blocked Drains was engaged to resolve a complex underground stormwater issue at a residential property in Scarborough, Queensland. A key section of the stormwater line—located directly beneath a concrete swimming pool—had been compromised by a concrete rebar intrusion, most likely from past construction. The pipe was also charged (partially full and under pressure), presenting serious access and repair challenges.
Site Conditions
- Restricted access: With the damaged pipe situated under a pool, traditional excavation methods were not feasible without major disruption or structural risk.
- Solid obstruction: A piece of rebar embedded in concrete had penetrated the stormwater pipe, creating a significant blockage.
- Active line: The pipe remained charged, adding complexity to the repair and requiring non-invasive, specialist equipment.
Our Solution
Our team used advanced robotic cutting technology to internally access the pipe and precisely remove the concrete and rebar obstruction without digging. This high-precision, trenchless method allowed for:
- Safe and targeted rebar removal from inside the pipe.
- Preservation of the surrounding infrastructure, including the pool.
After successfully clearing the blockage, we installed a 2-metre trenchless reline patch to seal and reinforce the damaged section. This involved lining the interior of the pipe with a high-strength, cured-in-place resin—effectively creating a brand-new pipe within the old one.
Project Outcome
- The job was completed with zero excavation, minimising impact on the property and avoiding costly restoration.
- The stormwater pipe was fully restored, and flow was returned to optimal performance.
- The result showcased SEQ Blocked Drains’ capability in tackling high-risk, no-dig repairs using robotic cutting and trenchless relining techniques.
