Pre-Construction TermiteBarriers North Strathfield
Collars, membrane and perimeter barriers installed to your builder's program across North Strathfield, from apartment slabs on the old Arnott's factory land to rebuilds on the older residential streets.
Yes. A new home or apartment building in North Strathfield needs an NCC termite management system installed to AS 3660.1. Collars and any under-slab work go in after the plumber's rough-in and before the pour. The durable notice for the meter box and an installation certificate for the City of Canada Bay certifier are both required before the Occupation Certificate is issued.

Why North Strathfield builds need the barrier in before the pour
North Strathfield is a City of Canada Bay suburb in postcode 2137, about 11.2 km west of the CBD. For most of the twentieth century it was an industrial area, best known for the Arnott's Biscuits factory that ran from 1908 to 1997. That site is now the Bakehouse Quarter, a precinct of offices, restaurants, cafes and shops, with Arnott's head office still there, and other former factory sites nearby have been redeveloped into higher-density apartments alongside the older residential streets. North Strathfield station, on the Northern Line, was upgraded in 2019, and building activity has followed close behind.
Redeveloping former industrial land is a different starting point for a termite barrier than building on an established garden. Sites that once carried factories or warehouses can have disturbed, filled or built-up ground, and getting a clean, fully sealed under-slab system on that kind of site matters just as much as on any bushland block, because buried debris and uneven fill can still give termites a path if the membrane and collars are not detailed properly. On the older residential streets away from the redevelopment sites, ageing houses bring the more familiar job of a knockdown rebuild on a mature, well-planted block.

Local conditions
What makes North Strathfield blocks a termite risk
Three things shape termite risk in North Strathfield, tied to how the suburb has changed from factories to homes.
Redeveloped former factory land
Apartment sites on former industrial land, including the streets around the old Arnott's factory footprint, can have disturbed or filled ground with buried debris from decades of industrial use. We treat the under-slab membrane and every penetration as the first line of defence on sites like this, since uneven fill can hide a path for termites if it is not detailed properly.
Knockdown rebuilds on older streets
Away from the redeveloped precinct, North Strathfield's older residential streets are mature, well-planted blocks with decades of garden beds and buried timber. That material can feed a colony long before a new slab goes down, so soil treatment and the under-slab system matter as much as the perimeter.
Dense apartment and mixed-use sites
New apartment buildings near the Bakehouse Quarter and North Strathfield station often carry a large number of penetrations on a single slab, shared with commercial space below. Collar counts and scheduling around the builder's program drive both the price and the timing on sites like these.
What we install here
Building in North Strathfield
We work on North Strathfield apartment and mixed-use developments near the Bakehouse Quarter and the station, knockdown rebuilds on the older residential streets, and granny flats behind established homes. Waffle pod and raft slabs are standard on detached rebuilds, while multi-dwelling sites on former industrial land need collar counts planned from the plans well before we arrive. You get one fixed written quote covering every stage, and we attend in stages so a barrier visit never holds up a pour.
Under-slab membraneA termite-resistant sheet laid across the prepared ground before the pour.
Penetration collarsCollars sealed to every pipe and conduit that comes up through the slab.
Perimeter & slab edgeA barrier at the slab edge and into the cavity, so nothing can track up hidden.
Chemical soil barrierAn APVMA-registered treated zone in the soil under and around the building.
ReticulationA pipe network laid before paving so the treated zone can be topped up later.
Piers & suspended floorsProtection for bearers, piers and suspended timber floors on sloping blocks.
Local knowledge
Around North Strathfield
Our North Strathfield work runs from the Bakehouse Quarter and North Strathfield station, where redeveloped factory land carries most of the newer apartment and mixed-use construction, out to the older residential streets near Ismay Reserve. Around Concord Golf Club, irrigated turf and ponds keep some neighbouring blocks damper for longer, which we factor into slab edge checks on properties that back onto the course.
The City of Canada Bay is the certifying council for North Strathfield, and it withholds the Occupation Certificate until it has a meter-box notice recording the termite system, along with a signed certificate from the installer that lists the products, the coverage and their licence details. Both are ready the moment our stage of a North Strathfield job wraps up.

The inspection zone. An exposed strip of slab edge lets anyone spot termite mud tubes before they reach the frame, which is why paving, soil and mulch must stay below it.

Does building on former factory land in North Strathfield change the termite barrier?
It changes how carefully the ground and the under-slab system need to be checked. Land that carried factories or warehouses for decades can have disturbed or filled soil with buried debris, so we make sure the membrane and every collar are fully sealed rather than assuming the fill is clean and uniform.
Do rebuilds on North Strathfield's older streets need special attention?
Yes. Established blocks on the older residential streets often carry decades of garden beds, old stumps and buried timber offcuts that can already be feeding activity nearby. We treat the soil treatment and under-slab system as seriously as the perimeter on a rebuild site like this. That groundwork matters just as much as the barrier around the new slab's edge.
Can you fit a barrier visit around an apartment construction program near the station?
Yes, that is common work for us in North Strathfield. Collars go on after the plumber's rough-in and before the pour, so we plan our visit around the builder's program and attend in stages on a multi-dwelling site without holding up the concreter or the next trade. We confirm the schedule with the site supervisor before our visit.
Does a new home need a termite barrier in NSW?
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.
What does a pre-construction barrier cost?
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.
