Boundary Trap Replacement & Inspection

What Is a Boundary Trap?

A boundary trap is the final connection point between your property's private drain and the water authority's sewer network. It marks the last point of the property owner's responsibility — everything beyond it belongs to your water authority.

The boundary trap, shaft, and lead off junction are the most common areas to fail in older properties; and due to the depth, repairs of this nature can often become very costly to repair.

Signs your boundary trap may need attention

• Slow or blocked drains throughout the property
• Sewage smell near the boundary of your property
• Gurgling noises from drains or toilets
• Drain overflowing at the inspection shaft
• Multiple blocked drains at the same time

Boundary Trap Relining — The No-Dig Solution

Where possible, Draintech will reline your boundary trap and lead-off junction without excavation. This trenchless method can save you thousands of dollars compared to a full dig and replace. It also means minimal disruption to your property.

Our relining solutions are suitable for cracked, root-damaged, or deteriorating pipes that still retain their basic structure.

When is a full boundary trap replacement needed?

When the pipes have collapsed, are severely misaligned, or relining is no longer a viable option, a full replacement is required. Draintech has replaced boundary traps at all depths and locations across Melbourne, always working toward the most cost-effective solution for our clients.

We use a range of excavation methods depending on the site conditions:

• Manual excavation: for tight or sensitive areas
• Hydro excavation: precise, non-destructive digging using pressurised water
• Mechanical excavator: for deeper or larger jobs
• Combination of methods: when the situation requires it

Our team members are all trained in trench shoring and excavation, and work to the highest level of safety to ensure your job is finished to meet our strict standards and specifications.
