Blacktown & Mount Druitt · AS 3660.1
Collars and perimeter barriers fitted before the pour on Acacia Gardens 2763 blocks, from the flower-named streets near Waite Reserve through to the Stanhope Gardens boundary.
Quick answer
New homes in Acacia Gardens are not exempt: the suburb falls inside a termite-prone part of the City of Blacktown, so the NCC requires a compliant system installed to AS 3660.1 before the slab is closed. Collars go on every penetration first. Once that is done, a durable notice is fitted in the meter box and an installation certificate is prepared for your certifier's records.
Termite barriers in Acacia Gardens
Acacia Gardens is a small residential suburb in postcode 2763, about 31 km north-west of the CBD, separated from Quakers Hill and formally recognised in 1996 within the City of Blacktown. Streets here largely carry flower names, and the housing is mostly detached family homes on suburban blocks close to Parklea, Stanhope Gardens, Kings Park and Glenwood. Because the suburb is relatively young, most new work is renovation, granny flat additions and the occasional knockdown rebuild rather than large-scale redevelopment, but each of those triggers the same termite management obligation as a first build.
Even on a younger block, established gardens, timber retaining walls and mulched beds built up against the slab edge give termites a quiet way in over time. The flat, open ground typical of this part of Blacktown means waffle pod and raft slabs are the norm, and a garden bed sitting hard against a slab edge or a pipe penetration left uncollared is exactly the kind of gap a barrier installed before the pour is designed to close. We look at how a block is landscaped as well as how it is built before pricing the system.

Local conditions
Three local factors shape how we plan a termite barrier for an Acacia Gardens build.
Even where the housing stock itself is only a few decades old, garden beds, retaining timber and mulch built up against the slab edge give termites cover close to the frame. Soil treatment around the footprint has to account for that landscaping, not just the bare slab.
Much of the current work here is extensions and secondary dwellings rather than whole new estates, and each addition or granny flat is its own structure under the NCC. We plan the new barrier to tie into or sit alongside the existing system where the layout allows.
The suburb's flat terrain suits waffle pod and raft slab construction, which keeps the barrier detail fairly consistent from block to block. The main variable is how close established plantings from neighbouring streets sit to the new footprint.
What we install here
In Acacia Gardens we install collars, membrane and perimeter systems for new homes, renovations that open up part of a slab, granny flats and the occasional knockdown rebuild among the suburb's family homes. Waffle pod and raft slabs are standard on the flat blocks here, and we time our visit around the plumber's rough-in so every penetration is collared before the concreter arrives. You get one fixed quote from the plans, and we stage our attendance so it never holds up the pour.
Local knowledge
Most of our work in Acacia Gardens sits within easy reach of Waite Reserve and the shops at Glenwood Village Shopping Centre, with the suburb's boundary running close to Parklea and Stanhope Gardens. Reserve edges and older plantings nearby are the main reason we check a block's landscaping as closely as its slab design, since mulch and garden beds built up against a footing are a common entry point regardless of how new the house itself is.
Acacia Gardens sits under the City of Blacktown for certification purposes, and the standard paperwork applies before an Occupation Certificate can be issued: a notice permanently mounted in the meter box recording the installed system, plus a certificate naming the products, protected areas and our licence. Both documents are finalised on the day we install the barrier, and we pass them on with product data and care instructions.

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

Acacia Gardens questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. A secondary dwelling is a separate structure under the NCC and needs its own compliant termite management system, even if the main house already has protection. We usually connect the new system to the existing one where the site layout allows, and issue a fresh durable notice and certificate for the new structure.
They do. Even where the house itself is relatively young, mulch, garden beds and retaining timber built up against the slab edge over the years give termites cover close to the frame. We check the landscaping as part of any renovation or addition, because it changes where the barrier needs the most attention.
As soon as the plumber has finalised the new pipe layout for the extension. Any new slab section or additional wet area needs its own collars and under-slab treatment before it is poured, and we schedule the visit to fit between rough-in and your concreter's booking so the extension is not delayed.
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.
