Inner West · AS 3660.1
AS 3660.1 termite barriers for heritage-sensitive Croydon rebuilds and infill near the heritage-listed station and The Strand, postcode 2132, across Burwood and Inner West Council.
Quick answer
Because Burwood and Inner West Council both sit within termite-prone territory, the National Construction Code demands a termite management system for any Croydon rebuild, duplex or infill development. AS 3660.1 is the installation standard, and the work wraps up before the slab pour. A durable notice for the meter box, along with an installation certificate, must reach the certifier before Occupation Certificate sign-off.
Termite barriers in Croydon
Croydon is a residential suburb about 8.9 km west of the Sydney CBD, in postcode 2132, split between the Municipality of Burwood and Inner West Council. Most houses are Federation-era and California bungalow designs from the early twentieth century, with just over half of dwellings still separate houses and the rest apartments and townhouses, centred on the heritage-listed station and The Strand shopping strip. Presbyterian Ladies' College, which moved to Croydon in 1891, and Burwood Girls High School are well-known local institutions. Because so much of Croydon's housing stock is heritage-era, new barrier work here is almost entirely knockdown rebuilds and careful renovation of older houses rather than large-scale new estates.
A Federation house or California bungalow being rebuilt in Croydon typically sits on a block that has carried timber floors, verandahs and established gardens for well over a hundred years, and that history matters to how the barrier is planned. Decades of buried timber and garden beds close to the original house can already be supporting termite activity before the new slab goes down, so the soil treatment underneath needs as much attention as the perimeter at the edge. Apartments near the station bring a different set of conditions, with shared roof voids and service risers rather than individual timber sub-floors. Whichever type of building, keeping the work discreet on a heritage streetscape matters as much as getting the barrier right.

Local conditions
Three things shape termite barrier work on a Croydon site.
Many Croydon rebuild sites replace Federation or California bungalow houses that carried timber floors, verandahs and mature gardens for over a century. That history can already be feeding termite activity in the soil, so the under-slab treatment on the new build matters as much as the perimeter.
With so much of Croydon's housing heritage-listed or heritage-influenced, barrier installation on a rebuild has to fit within streetscape expectations. We plan access and any visible elements, like the durable notice in the meter box, to sit neatly within a heritage-sensitive property.
Development near Croydon station and The Strand is mostly apartments and townhouses rather than detached houses, with shared roof voids and service risers on a single slab. These sites need collar counts and a certificate matched to every dwelling on the building.
What we install here
Most of our Croydon work is knockdown rebuilds of Federation and California bungalow houses, along with apartment and townhouse infill near the station and The Strand. Waffle pod and raft slabs are common on rebuild sites, while apartment developments bring a shared slab with multiple penetrations across several dwellings. We work carefully around established gardens and heritage streetscapes, and stage the barrier visit around the plumber and concreter so it never holds up a Croydon pour date.
Local knowledge
Croydon station, about 0.1 km from the suburb centre, is a heritage-listed landmark that anchors The Strand shopping strip and the apartment development around it. Reed Reserve, within the suburb itself, and Ashfield Aquatic Centre, about 0.5 km away, are closer to many of the detached rebuild sites. Westfield Burwood, about 1.2 km off, marks where Croydon's own streets give way to the wider Burwood area. Presbyterian Ladies' College and Burwood Girls High School mark Croydon's long institutional history but have little direct bearing on how a barrier is detailed on a residential rebuild.
Certification for Croydon falls to either the Municipality of Burwood or Inner West Council, depending on where a property sits. Both want the same two records before the Occupation Certificate: a durable notice for the meter box, plus an installation certificate naming the products, areas protected and installer. On a heritage-era rebuild, we also record the site conditions the barrier had to work with, so the paperwork reflects both what the block carried and what was newly installed.

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.

Croydon questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Often yes. A block that has carried a Federation or bungalow house for over a century usually has decades of garden beds and buried timber close to the soil, which can already support termite activity. The new build still gets a standard AS 3660.1 system, but the soil treatment is planned around what the site has been carrying.
Yes, we plan access and visible elements like the durable notice in the meter box to sit within a heritage-sensitive streetscape, which matters given how much of Croydon's housing near the station and The Strand is Federation or California bungalow era. The requirements under AS 3660.1 do not change, just how the work is carried out on site.
Yes, an apartment or townhouse development on a shared slab needs one certificate covering every dwelling on the building, naming the products used and the areas protected across the whole site. A single detached rebuild gets its own certificate sized to that one property, without the extra coordination a multi-unit site needs.
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.
