Inner West · AS 3660.1
We size the termite system to the block, whether it's a rebuild near the Turrella rail corridor and station or one of the streets that back directly onto the Wolli Creek Valley bushland.
Quick answer
Yes. A termite management system is required before a new Turrella home gets its Occupation Certificate, because the suburb borders remnant bushland in the Wolli Creek Valley, a termite-prone setting under the NCC. That system must meet AS 3660.1, with collar and perimeter work finished ahead of the concrete pour and the paperwork lodged with Bayside Council afterwards.
Termite barriers in Turrella
Turrella is a small, mostly residential suburb in Bayside Council, about 9.5 km south-west of the Sydney CBD in postcode 2205. Its housing runs from older cottages near the rail line to more recent infill, with light industrial premises still clustered around Turrella station and along the rail corridor to the north. The suburb's defining feature is its edge onto the Wolli Creek Valley, remnant bushland that residents fought to protect from the M5 motorway, which was tunnelled underneath instead. Most of our work here is single knockdown rebuilds and the occasional granny flat, rather than large multi-dwelling sites.
Living beside that valley changes what a barrier needs to do compared with most inner suburbs. Wolli Creek keeps the soil along the bushland edge damp, and termites forage through that moisture from stumps and fallen timber in the reserve. Blocks close to the valley or to the light industrial land near the station carry more established colony pressure than a typical inner suburb, so getting the perimeter and every penetration right before the pour matters more here than it would a few streets further away from that bushland edge.

Local conditions
Three things drive termite risk on a Turrella block, and each one changes where we put the emphasis in the barrier.
Turrella backs directly onto remnant bushland in the Wolli Creek Valley, where fallen timber and leaf litter hold established termite colonies close to residential fence lines. Blocks on that edge get a full perimeter system rather than a partial strip, with careful detailing where gardens meet the reserve.
Wolli Creek keeps ground along its banks damp for long stretches of the year, and that moisture is what subterranean termites rely on to forage between the bushland and nearby homes. We treat the soil around the slab edge with that persistent dampness in mind, not just the driest months.
Turrella station and the light industrial sites along the rail line to the north add drains and sheltered ground that rodents use to move between properties. On new builds near that corridor, we check that penetrations and slab edges near boundary fences are fully sealed against both termites and rodent entry.
What we install here
Turrella work for us runs to knockdown rebuilds, new houses on subdivided blocks and granny flats behind existing homes, plus the odd duplex site closer to the station. Slab-on-ground construction is standard on these blocks, and collars go on once the plumbing rough-in is finished, ahead of the perimeter system going down before concrete arrives. Every quote is one figure taken straight off the plans, timed to fit your concreter's booking rather than sit in its way.
Local knowledge
Most of our Turrella work sits close to the Wolli Creek Regional Park boundary, where bushland edges are where termites, funnel-web spiders and possums most often cross into gardens. Arncliffe Park, a short walk from the station, adds another pocket of lawn and leaf litter that keeps pest pressure up on nearby blocks. Around Turrella station and the light industrial strip, drainage and rail corridor access shape how we detail penetrations near boundary fences.
Bayside Council certifies new builds in Turrella, and its checklist for the Occupation Certificate always includes evidence of a compliant termite system. We leave a notice permanently fixed inside the meter box describing that system, and issue a separate installation certificate covering the products used, the areas they protect and who carried out the work. Both arrive with the product data sheets well ahead of your final inspection date.

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

Turrella questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Speak to us as soon as demolition of the old dwelling is scheduled. We need a firm idea of when the plumber will rough in the new services, because collars go on straight after that and the barrier has to be finished before the concreter shows up, and on a small suburb like this the trades often book in close together.
Generally yes. The colony pressure along that bushland edge is older and more established than what you'd find on a typical inner suburban block, so the treated zone extends the full length of the boundary rather than stopping short. We also look hard at the fence line itself, since that's usually the first thing termites reach before the house.
Yes, and it's a common request given how many Turrella blocks are big enough for a second dwelling. The smaller footprint still needs full collar coverage and its own paperwork, but if the original house already has a system in place we look at how the two can work together rather than treating the block twice over.
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.
