Inner West · AS 3660.1
Collars and perimeter barriers going in before the pour on Concord rebuilds around Queen Elizabeth Park, Majors Bay Reserve and the garden blocks off Majors Bay Road.
Quick answer
Rebuilding in Concord, yes, the termite management system is not optional, Canada Bay council checks for it before the Occupation Certificate goes out. This is termite-prone ground, so the job is built to AS 3660.1: collars fitted, soil or membrane work done, all wrapped up before the slab is poured. We put together the meter box notice and the installer's paperwork once that stage is finished.
Termite barriers in Concord
Concord is a residential suburb about 9.5 km west of the Sydney CBD, in postcode 2137 and the City of Canada Bay. It is often called the Parkland Suburb, with Queen Elizabeth Park, Majors Bay Reserve, Concord Oval and many smaller reserves scattered through it, and it borders several bays and inlets of the Parramatta River. The Majors Bay Road shopping village has cafes, restaurants and a supermarket, and Parramatta Road runs along the southern edge. Housing is mostly detached family homes on garden blocks, with some units, and new construction is largely knockdown rebuilds and extensions on those established blocks, since Concord is fully built out. Whatever the scale of the project, council checks for a compliant termite system before agreeing to close the file.
In Concord, gardens, trees and parks are the biggest influence on termite risk. Established gardens and large trees support activity close to many blocks, and moist soil near the bays and reserves suits subterranean termites working underground toward a new slab or extension footing. Many homes have been extended over the years, and each addition can create a hidden gap or a damp corner where a barrier was never properly closed off. Because so much of the suburb sits near a reserve or a stretch of the Parramatta River foreshore, we treat the surrounding garden as part of the assessment, not just the building footprint, before recommending a system for a Concord rebuild.

Local conditions
Three things about Concord's parks and waterways shape termite risk on a rebuild here.
Queen Elizabeth Park, Majors Bay Reserve and the many smaller reserves scattered through Concord all add mulch, garden beds and mature trees that can shelter termite activity close to nearby blocks. Properties backing directly onto one of these reserves usually need a fuller perimeter.
Blocks close to the Parramatta River's bays and inlets hold moisture in the ground for longer than blocks further inland, and a colony working through wet soil rarely announces itself before it reaches a slab. We pay particular attention to slab edges on these blocks.
Many Concord houses have been extended more than once over the decades, and each addition creates a join in the structure where a barrier can be interrupted if it was not properly detailed at the time. A rebuild or new extension needs the whole building checked, not just the new section.
What we install here
Almost everything we do in Concord is a knockdown rebuild or an extension on an established garden block near one of the suburb's parks or reserves, since so little vacant land remains. Waffle pod and raft slabs are standard here. Collar timing follows the plumber's rough-in, and on an addition we start by working out how the original house was protected, then tie the new barrier into it wherever the old detailing allows. Every job is costed as one fixed written quote covering the whole scope of work.
Local knowledge
Edwards Park and Massey Park Golf Course sit close to much of our Concord work, where mulch, garden beds and irrigated turf keep the surrounding ground damp for longer after rain. Cabarita Shopping Centre and the wider Majors Bay Road strip add food waste that draws other pests, while Concord Oval and Queen Elizabeth Park, toward the centre of the suburb, are where many of the largest established gardens and mature trees sit close to residential blocks.
Canada Bay is the certifying council for Concord, and the Occupation Certificate does not get released until two things exist: a meter box notice naming the system, and a written record from us covering what products went in and where. For an extension we make a point of describing how the new work connects to whatever protection the original house already had, so a certifier sees one coherent property rather than two separate jobs.

Systems we install
Every photo below is from one of our own Sydney jobs. We look at your slab design, site and budget, then recommend a system or a combination.
01A termite-resistant sheet laid over the whole prepared footprint before concreting, so termites can't come up through the slab anywhere.
02A sealed collar on every pipe, conduit and service that passes through the slab. These gaps are the most common hidden way in.
03Protection at the slab edge and into the wall cavity, which stops termites building hidden tunnels up the outside of the slab.
04An APVMA-registered termiticide zone in the soil, with an optional pipe network under paving so it can be recharged later without digging.
05Barriers for bearers, piers and raised timber floors on sloping or elevated blocks, where there's no slab to protect.
06Detailing for sandstone cuts, block retaining walls, step-downs and cut-and-fill sites, which are common across Sydney.
Why during construction
A retrofit can only treat around a finished house. A pre-construction system protects the parts nobody will ever be able to reach again.
A barrier put in during the build costs a fraction of a post-construction system, and far less than repairing termite damage.
New houses (Class 1) and outbuildings (Class 10) with termite-susceptible framing need a compliant termite management system.
Pipe penetrations and slab joints can only be fully protected while they're still open, before the concrete goes in.
An under-slab system covers ground that no treatment from outside the finished house can ever reach.
Your certifier needs the certificate and durable notice before issuing the Occupation Certificate. We supply both together.
Documented, compliant protection gives buyers, building inspectors and lenders confidence when the home is sold.
Installation stages
A termite barrier isn't a single visit. Each part goes in when the site is ready for it, and we fit around your plumber, concreter and bricklayer.
Send your plans and slab details. We recommend a system and give you one fixed price that covers every stage.
Collars go on every service once the plumber has set out, then the membrane or soil treatment is installed across the prepared site.
Perimeter and cavity protection is fitted as the brickwork or cladding goes up, so there's no unprotected gap at the slab edge.
Where it's specified, the chemical perimeter or reticulation system is completed around the building before paths and gardens go in.
A durable notice goes in the meter box, and the installation certificate goes to your builder and certifier.
The owner gets simple care instructions and an inspection schedule so the system keeps doing its job for years.
Compare systems
Both can meet AS 3660.1. The best choice depends on your slab type, what surrounds the house and how much ongoing upkeep the owner wants.
Physical protection
Entry-point protection
Soil protection
Top-up protection
Most of the Sydney builds we work on use a combination: physical collars on every penetration plus a physical or chemical perimeter.
For builders & developers
Builders, developers and owner-builders get a fixed quote from plans, a technician who turns up when the site is ready, and paperwork that never holds up sign-off.
Consistent pricing across lots, one point of contact and a full document set for every dwelling.

Concord questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Reserves like Queen Elizabeth Park and Majors Bay Reserve, along with the many smaller parks scattered through Concord, hold established garden beds and mature trees that can shelter termite colonies close to nearby blocks. Properties backing directly onto one of these reserves typically get a fuller perimeter than a block set well back from any park, since the pressure is more direct.
It can. Older extensions sometimes have a gap or a poorly detailed join where the original barrier, if there was one, was never properly continued. When we work on a further addition or a rebuild, we check how the existing structure was protected and tie the new system into it, so the whole property ends up covered under one certificate.
Ground close to Concord's bays and inlets tends to stay damp for longer than blocks further from the water, and that moisture is exactly the condition subterranean termites use to move toward a structure without being noticed. We usually pay closer attention to slab-edge detailing on these blocks, since a gap is more likely to be found and used in consistently damp ground.
In most cases, yes. The National Construction Code requires a termite management system for new houses and outbuildings in termite-prone areas where the primary building elements can be damaged by termites. Sydney is termite-prone, so the system is installed to AS 3660.1 and your certifier asks for the installation certificate and durable notice before the Occupation Certificate is issued.
It depends on slab area, perimeter length, the number of pipe penetrations, the system chosen, site complexity and how many visits the build needs. Send us the plans and we return one fixed written quote covering every stage. Quoting is free.
