Blacktown & Mount Druitt · AS 3660.1
New estates now ring Schofields station and the old Nirimba Fields land, postcode 2762, and every fresh slab going down on this growth-area ground needs a termite barrier fitted first.
Quick answer
Yes, a new home in Schofields needs a termite management system, because the suburb sits in a termite-prone part of the North West Growth Area and the NCC requires one for every new house. The system is installed to AS 3660.1 before the slab is poured, with collars on every penetration. A durable notice and an installation certificate for the certifier are both required before the Occupation Certificate.
Termite barriers in Schofields
Schofields is part of the North West Growth Area in the City of Blacktown, about 36.6 km north-west of the CBD in postcode 2762. Named after John Schofield, a former convict who bought land here in 1845 and later ran a sawmill beside the railway line that opened in 1864, the suburb once held Schofields Aerodrome and HMAS Nirimba before 2020 boundary changes created Nirimba Fields and Tallawong. New estates now surround the station, with a Woolworths and Schofields Village Shopping Centre opposite. Most of our work here is new house-and-land builds and the occasional duplex, going down as the growth area continues to develop.
The switch from farms and acreage to new housing is the biggest factor in how we detail a Schofields barrier, since earthworks across a growth area like this disturb ground that had settled for decades under paddocks and dams. Older rural properties that remain nearby still have sheds, dams and paddocks that suit termites as much as any bushland does, and that history can sit right next to a brand-new estate boundary. A fresh slab on this kind of ground needs the same careful barrier work as an established suburb, because new construction doesn't remove what termites left behind in the soil.

Local conditions
Three things shape how we detail a barrier on a Schofields block.
Schofields is still converting from farms and acreage to new housing, and that transition disturbs ground that had settled under paddocks for generations. Earthworks across a growth area like this can shift termite activity onto adjoining estate blocks.
Older rural properties still standing near new estates carry sheds, dams and paddocks that suit termites as much as any established bushland. A new slab going in nearby needs the same careful barrier as one backing onto a reserve.
Most Schofields homes are new builds on cleared land, so this is often the first termite management system the ground has ever carried. Getting collars and the perimeter right at construction avoids relying on repairs after the slab is closed.
What we install here
Our Schofields work is almost entirely new house-and-land builds across the growth area, along with duplexes and the occasional secondary dwelling as estates mature. Waffle pod slabs are standard on this flat, open ground. We fit collars to every pipe and conduit penetration and run the perimeter to the true boundary, working closely with the builder's program so our visit lands between the plumbing rough-in and the pour without holding up the schedule, which matters most on a fast-moving growth-area site.
Local knowledge
Schofields station sits at the centre of the new estate development, and the rail corridor running past it is a reminder of how much has changed here since the line first opened in 1864. Altrove Hilltop Park, one of the newer estate parks, shows how quickly fresh plantings and mulch have gone in alongside the housing, ground cover we factor into any nearby barrier plan. With Riverstone, Quakers Hill, The Ponds and Dean Park all close by, Schofields sits in the middle of a stretch of Sydney that is still very much under construction.
Schofields is certified through the City of Blacktown. Two things need to be on record before it will grant an Occupation Certificate: a durable notice fitted in the meter box, and an installation certificate that names the products, the areas covered and the licensed installer. On a fast-moving growth-area build, we get both across to the certifier the moment our stage is done, so paperwork never becomes the delay.

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.

Schofields questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215As soon as you have a rough slab date from your builder. Collars and any under-slab system go in after the plumber's rough-in and before the concrete pour, so we lock our visit around your trades' schedule. On growth-area sites this timing can move quickly, so early contact keeps the barrier from becoming a delay.
Where a new estate sits close to remaining sheds, dams or paddocks, termite pressure can be steadier than on a block well inside the estate, because that older rural land still suits termites the way bushland does elsewhere. We check what's next door before finalising a barrier plan for a new build in that position.
Schofields is certified through the City of Blacktown, which needs a durable notice mounted in the meter box and an installation certificate naming the products, the treated areas and the licensed installer before it grants an Occupation Certificate. On a fast-moving estate build we get both ready as soon as our stage finishes.
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.
