Eastern Suburbs · AS 3660.1
Barrier work timed to the slab for Eastgardens 2036 duplex, townhouse and infill sites clustered near Westfield Eastgardens, Mutch Park and Bonnie Doon Golf Course.
Quick answer
Yes. New dwellings in Eastgardens fall under the same National Construction Code rule as anywhere else in this part of Sydney: a termite management system is compulsory. Collars go on and membrane is laid to the AS 3660.1 standard before the slab is poured. Two documents then follow: a durable notice posted inside the meter box, and an installation certificate, both needed before the Occupation Certificate is granted.
Termite barriers in Eastgardens
Eastgardens is a compact Bayside Council suburb about 8.7 km south of the CBD in postcode 2036, built on land once used as a bus depot and a Holden manufacturing plant before Westfield Eastgardens opened there in 1987. There is little vacant land left, so new work here is almost always redevelopment: a knockdown replaced with a duplex or a pair of townhouses, a tired unit block making way for something denser, or a granny flat added behind an existing house. Even a small site still goes through the same slab-stage planning as a much bigger job.
Every one of those projects still needs a termite management system, and a tight infill block changes how it gets installed rather than whether it is needed. Shared boundary walls, narrow side access and a new slab sitting close to an established neighbour's garden all affect where collars and perimeter treatment can go. Being minutes from a major shopping centre also means service trenches, bin areas and landscaping works nearby, all of which can disturb soil right up to a new pour. We plan around that disturbance rather than treating each site as if it stood alone.

Local conditions
Three things about Eastgardens shape how a barrier gets fitted on an infill block.
Duplex and townhouse splits here usually sit hard against a neighbour's fence line with limited access. We plan the collar and perimeter layout around those boundaries before work starts, so nothing gets missed at a party wall.
Knockdown sites often carry buried timber, old stumps and garden beds from the house that came down, all of which can feed termite activity before the new slab is even poured. Soil treatment ahead of the pour matters as much as the barrier itself.
Mutch Park and Bonnie Doon Golf Course sit within a kilometre of most Eastgardens streets, and turf, garden beds and mature trees near a build site can carry termite activity onto an adjoining block once construction disturbs the ground nearby.
What we install here
In Eastgardens we mostly work on knockdown rebuilds, duplex splits, granny flats and small townhouse developments rather than large estates, since there is very little vacant land left in the suburb. Waffle pod and raft slabs are typical, and on tighter sites we fit collars and perimeter treatment in stages to work around narrow side access and a builder's crane or hoarding. One fixed quote covers the whole job from the plans.
Local knowledge
Most of our work sits within easy reach of Westfield Eastgardens, Mutch Park and Bonnie Doon Golf Course. Blocks backing onto the golf course or the park get extra attention to the perimeter where garden beds and turf run close to the new slab, while sites nearer the shopping centre tend to be tighter, higher-density infill with less garden to consider but more shared boundaries to plan the barrier around.
Bayside Council handles certification for new dwellings in Eastgardens. Before signing off the Occupation Certificate, the certifier wants proof the system is compliant: a durable notice inside the meter box, plus an installation certificate covering the products, the protected areas and who fitted it. We put this together as soon as the barrier work wraps up, alongside the relevant product data sheets.

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.

Eastgardens questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Generally yes, since each dwelling on the title typically gets its own slab and its own certificate. We plan the collar and perimeter layout for both halves together so the coverage is continuous across the shared wall, then issue separate documentation for each certifier submission where the two dwellings are being titled and sold apart from each other.
We treat these carefully because established gardens often hide old stumps, roots and buried timber that can support termites well before the new slab goes down. We assess the site and recommend soil treatment alongside the physical barrier where the ground history warrants it, then fit collars and perimeter coverage to match the new footprint once demolition is complete.
Yes. A secondary dwelling gets its own collars and perimeter or under-slab system sized to its slab, installed without needing access to the existing house. If the main house already carries protection, we connect the new system to it where the layout allows, and where it does not we simply run the granny flat as its own separate, fully compliant install.
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.
