St George & Bayside · AS 3660.1
Barriers fitted before the pour on Bexley North blocks that back onto Bardwell Creek and the Prime Minister's Walk, and on rebuild sites near the station shops.
Quick answer
Yes, a rebuild or new home in Bexley North needs a compliant termite management system, since Bayside Council's area is termite-prone under the NCC. Built to AS 3660.1, the collars go on and any under-slab work is finished before the concrete truck turns up, then the durable notice and installation certificate follow ahead of your Occupation Certificate.
Termite barriers in Bexley North
Bexley North sits around its own station on the Airport and South Line, with a small shopping strip at Bexley Road, Slade Road and Shaw Street and the M5 tunnel running beneath the suburb without any local exit. Away from that centre it is a mix of established family homes, so the pre-construction work we see is mostly knockdown rebuilds, granny flats and small infill sites rather than large new estates. Bayside Council certifies these builds, and each one needs a compliant termite management system installed before the concrete is poured and before the Occupation Certificate can be signed off.
Bardwell Creek and the Prime Minister's Walk run through the suburb towards Bexley Pool, with Stotts Reserve and Gilchrist Park breaking up the residential streets along the way. Creek lines like that keep the soil around nearby blocks damp for longer after rain, which suits subterranean termites foraging out from the vegetation on both sides of the corridor. A new slab close to that corridor needs the collars, membrane and perimeter detailed properly at every penetration and edge, because a damp, well-fed colony nearby will find any gap that a rushed or generic install leaves open.

Local conditions
Three things drive termite pressure on a Bexley North block, and they change what the barrier needs to do.
Bardwell Creek and the Prime Minister's Walk keep soil moist well beyond the creek banks themselves, and colonies established along that corridor forage into nearby gardens, so blocks closer to the creek get a fuller perimeter treatment.
The station and the M5 tunnel beneath the suburb mean underground services and drainage lines run close to some blocks, and every one of those penetrations through a new slab needs a properly sealed collar.
Family homes here often carry mature trees and long-standing garden beds, and demolishing a house does not remove the timber and organic material left in the soil, so we check what a knockdown rebuild site is sitting on before quoting the barrier.
What we install here
Bexley North work is mostly knockdown rebuilds, granny flats and small duplex or townhouse infill, with the odd commercial slab near the station shops. Waffle pod or raft slab systems are standard, with a collar fitted to every plumbing and conduit line before the pour, then the perimeter barrier run once the walls are up. We quote the whole job once from your plans, staged around your builder so a barrier visit never holds up the pour.
Local knowledge
Blocks closer to Gilchrist Park and the Prime Minister's Walk sit nearest the creek corridor, so we give the perimeter there more attention than a dry inland block would need. Around the station and the Angelo Anestis Aquatic Centre, sites are tighter and multi-dwelling work is more common, with collar counts driven by how many services come up through a single slab. Either way the price comes from your plans before we start.
Bexley North builds go through Bayside Council for certification. Ahead of the Occupation Certificate, your certifier wants two things: a notice screwed to the inside of the meter box describing the system, and an installation certificate listing the products used, the treated areas and the licensed installer. We supply both, together with product information and ongoing maintenance advice, so nothing is missing at sign-off time.

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

Bexley North questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Blocks close to the creek and the Prime Minister's Walk sit nearest an active foraging corridor, so we usually recommend a fuller physical perimeter rather than a token strip. The soil stays damp longer near the creek, which keeps termite activity going, so the barrier is detailed to suit that rather than a standard inland block.
After the plumber has set out the services and before the concreter pours, which is the only window where a collar can be sealed properly around a pipe or conduit. We coordinate that visit directly with your builder, plumber and concreter so the barrier fits your program rather than the other way around.
Yes. A secondary dwelling is held to the same standard as a new home, with its own collars, its own under-slab or perimeter system sized to the smaller footprint, and its own paperwork for the certifier. Where the main house already carries a system, we tie the new work into it as far as the layout allows.
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.
