Blacktown & Mount Druitt · AS 3660.1
Barriers installed before the pour on Blackett rebuild and granny flat sites, in the streets named after Australian writers that back onto Popondetta Park and the leisure centre.
Quick answer
Yes, a new home, secondary dwelling or rebuild in Blackett needs a termite management system under the NCC, because the City of Blacktown sits in a termite-prone part of Sydney. Working to AS 3660.1, we finish the collars and any under-slab system before the pour, then hand your certifier the durable notice plus installation certificate before occupation is sought.
Termite barriers in Blackett
Blackett grew from the 1970s as part of the Mount Druitt public housing development, with many of its streets named after Australian writers and commercial activity limited to a small shopping strip. With little vacant land left, the building work we see is knockdown rebuilds and granny flats on existing house blocks rather than new estates. The City of Blacktown handles certification here, and any new slab still calls for a compliant system, collars and all, before the concrete goes down, regardless of how established the surrounding street already is.
Homes from that era have now been lived in for decades, and the large open space of Popondetta Park runs along one side of the suburb. Between the age of the surrounding housing stock and the parkland edge, a rebuild site here typically sits close to established termite activity in older sub-floors and fence lines, as well as garden beds that have never been treated. Detailing the collars, membrane and perimeter properly before the pour is what keeps that pressure away from the new build rather than letting it find a way in later.

Local conditions
Three local conditions shape how we detail a Blackett barrier.
The park's sporting fields, trees and edges give rodents, ants and other pests shelter close to nearby homes, and blocks along that boundary need the perimeter barrier extended fully to the fence line rather than stopped short.
Blackett's 1970s public housing has carried fifty years of wear, and termite activity built up in older sub-floors and fences over that time puts pressure on any new slab built close by, so we treat the soil as carefully as the edge.
Most Blackett rebuild sites have never had a termite barrier installed on the block before, so old fence posts, sheds and garden timber in the soil can already be feeding a colony ahead of the new slab going down.
What we install here
Most Blackett work is knockdown rebuilds and granny flats on established house blocks. Waffle pod and raft slabs are standard, collars are set on every plumbing and conduit penetration before the pour, and the perimeter and soil treatment follow once the build is underway. One written quote from the plans covers every stage, and we fit the visit around your builder so the barrier stays in step with the pour date.
Local knowledge
Blocks along Popondetta Park sit closest to open grass and tree cover, so we extend the perimeter fully to that boundary rather than leaving a gap at the fence line. Closer to the small shopping strip and Emerton Village, sites are more built up but carry the same decades-old housing pattern, so the soil treatment gets the same attention across most of the suburb regardless of exact position.
The City of Blacktown certifies Blackett builds. Two things are needed before the Occupation Certificate can be issued: a notice housed in the meter box describing the termite management system installed, plus an installation certificate that names the products, areas protected and licensed installer. We supply both documents with product data sheets and maintenance advice, so your sign-off is not delayed.

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.
Missing durable notices and unclear install records are a common reason Occupation Certificates get held up. We hand everything over together so your certifier has it all in one go.
Paperwork
A complete document set for the builder, the certifier and every future owner of the property.
A permanent notice in the meter box showing the system, install date, installer, any chemical's life expectancy and inspection advice.
For: certifier, owner, future owners
Written confirmation of the system and products used, the areas protected and our licence details.
For: builder, certifier, owner
Details of the physical system or termiticide installed, including safety data sheets for any chemicals.
For: builder, owner

Blackett questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes, blocks along that boundary sit closest to grass, trees and shelter that pests including termites use, so we extend the perimeter fully to the fence line rather than a shorter strip. The rest of the barrier is installed to the same standard as any other Blackett rebuild, and priced the same way from your plans.
We check the soil for old fence posts, stumps and garden timber before quoting, since fifty-year-old blocks often carry material that can already be feeding a colony. That does not change the standard system required, but it does affect how thoroughly the soil treatment needs to be carried out before the slab goes down.
Yes, we treat a secondary dwelling as its own project: collars at every penetration, a compliant system scaled to the smaller footprint, and its own durable notice and installation certificate. If the main house already carries protection, the new work is connected into it wherever the block's layout allows for that.
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.
