South West Sydney · AS 3660.1
Collars and perimeter barriers fitted before the pour on Bonnyrigg Heights family home rebuilds, in the quiet streets around Freeman Catholic College and the local parks.
Quick answer
Yes, a new home, granny flat or rebuild in Bonnyrigg Heights needs a termite management system under the NCC, since the City of Fairfield area is termite-prone. Every collar and any under-slab element goes in to AS 3660.1 standard before the pour, and the durable notice plus installation certificate reach your certifier ahead of the Occupation Certificate.
Termite barriers in Bonnyrigg Heights
Bonnyrigg Heights is a quiet, family-oriented suburb in the City of Fairfield, home to schools including Freeman Catholic College and Bonnyrigg Heights Primary, a local fire station and community hall, and a good spread of parks and walking tracks for its size. With the area largely built out, the work we see is mostly knockdown rebuilds and granny flats on established family blocks rather than new estates. The City of Fairfield is the certifying authority, and each project calls for a compliant system, fitted before the pour, on the way to a signed-off Occupation Certificate.
Family backyards here typically come with play equipment, pets and vegetable patches, and a lot of owners want the barrier and any pest treatment carried out with children and animals in mind. Garden sheds, garages and the soil around them are also where a rebuild site's history often shows up, since decades of family use tends to leave buried timber, old fence posts and garden edging in the ground. Getting the collars, membrane and perimeter installed properly before the new slab is poured means that history stays outside the building rather than becoming part of its foundations.

Local conditions
Three things shape how we approach a Bonnyrigg Heights barrier, tied to the suburb's family character.
Vegetable patches, sheds and play areas built up over years on a typical Bonnyrigg Heights block often leave buried timber and garden edging in the soil, and that material can sustain a colony long before a rebuild's new slab is ever poured.
Reserves like Aplin Road Reserve sit close to residential streets, and their turf edges, trees and leaf litter give ants, spiders and termites shelter that can move into neighbouring backyards, so nearby blocks get attention at the boundary.
Many Bonnyrigg Heights owners want any pest work carried out with children and pets in mind, and we plan the barrier and any soil treatment around that, using methods and timing that suit a family home rather than an empty block.
What we install here
Bonnyrigg Heights work is mostly knockdown rebuilds and granny flats on established family blocks. Waffle pod and raft slabs are standard, each plumbing and conduit line gets a sealed collar before the pour, with the perimeter and soil treatment following on once the build is under way. One written quote from the plans covers every stage, and we plan the visit around your builder so the barrier never lags behind the pour date.
Local knowledge
Blocks near Aplin Road Reserve and the suburb's other small parks sit closest to turf and tree cover that shelter termites and other pests, so we give the perimeter extra attention on that boundary. Closer to Green Valley Village Shopping Centre, sites are a little more built up, but the same family-home pattern of sheds, gardens and play areas applies across most of the suburb.
The City of Fairfield is the certifying authority for Bonnyrigg Heights builds. Two things sit ahead of the Occupation Certificate: a notice recording the system, mounted in the meter box, and an installation certificate summarising the products used, areas protected and licensed installer. Both documents are handed over at project handover, complete with product data sheets and maintenance advice for the family.

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

Bonnyrigg Heights questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Blocks backing onto the reserve sit closest to turf and tree cover that shelter termites and other pests, so we extend the perimeter fully to that boundary. The rest of the barrier is installed to the same standard as any other Bonnyrigg Heights rebuild, priced from your plans before we start the job.
Yes, we plan visits and any soil treatment with children and animals in mind, using methods and timing suited to an occupied family home rather than a vacant block. Tell us about pets or play areas when you book and we will work around them and plan the visit accordingly.
Yes, a granny flat gets its own full system: collars at every penetration, a barrier scaled to the smaller slab, and its own certificate for the certifier. If the main house was protected when it was built, the new work is connected into that existing system wherever the layout makes it practical to do so.
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.
