Lower North Shore · AS 3660.1
Under-slab membrane, collars and a perimeter system fitted to AS 3660.1 for Neutral Bay apartment and podium slabs, from Neutral Bay Junction down to the wharf on Hayes Street.
Quick answer
Yes, new building work in Neutral Bay, postcode 2089, needs a termite management system. North Sydney Council sits in a termite-prone area, so the National Construction Code applies to apartment podiums and house renovations alike, built to AS 3660.1. Collars and under-slab work happen before the concrete is poured, and we prepare an installation certificate and durable notice for the certifier ahead of the Occupation Certificate.
Termite barriers in Neutral Bay
Neutral Bay is about 4 km north of the CBD in postcode 2089, within the North Sydney Council area, and is overwhelmingly a suburb of flats and apartments, with a smaller share of semi-detached homes and houses. Military Road forms Neutral Bay Junction, a shopping district of restaurants, cafes and the Big Bear shopping centre, and at the southern end of Hayes Street, Neutral Bay wharf takes public and private ferries across the harbour. Nearly all our work here is an apartment or mixed-use podium slab, with the occasional renovation on one of the suburb's remaining houses.
A suburb built mostly out of flats changes what a termite barrier has to cover. A podium slab can carry dozens of plumbing and service penetrations feeding shared bin rooms, laundries and garages, so every one of them needs its own collar planned from the drawings rather than fitted on the day. The harbour keeps the ground under basements and lower floors damper than it would be further inland, which suits subterranean termites as much as it suits any other pest that likes a humid, sheltered space, so drainage and ventilation around the perimeter get the same attention as the collars themselves.

Local conditions
Three things about Neutral Bay, tied to its density and the harbour, drive how a barrier is detailed here.
Apartment and mixed-use developments here typically pour one large slab carrying dozens of plumbing and service penetrations for shared bin rooms, laundries and garages. Each one is planned from the drawings and collared individually before the pour.
Proximity to the harbour keeps basements and lower-level ground damper than an inland North Sydney site, and that moisture is exactly what subterranean termites look for. We build extra drainage and ventilation checks into the perimeter design.
Older walk-up buildings around the suburb share laundries, bin enclosures and plumbing risers between units, and those shared spaces are often where pest activity is first noticed. We inspect the existing building before pricing any renovation work.
What we install here
Most of our Neutral Bay work is an apartment or mixed-use podium slab near Military Road or the wharf, with renovations and extensions on the suburb's remaining detached and semi-detached houses. We size collars from the plumbing and service drawings on multi-dwelling jobs and match the membrane and perimeter to the slab design. One fixed quote from the plans covers the whole job, and we time our visit to sit inside your builder's own construction schedule.
Local knowledge
Hayes Street Beach and the wharf sit at the bottom of the suburb, where harbour humidity is felt most in lower-level storage areas and basements nearby. Cammeray Golf Course, with its irrigated turf, adds moisture to the ground along that boundary. Around Military Road and Neutral Bay Junction, where the suburb's shops and restaurants cluster, our work is almost entirely apartment and mixed-use podium construction rather than standalone house rebuilds.
North Sydney Council certifies building work across Neutral Bay, and before it will release an Occupation Certificate it needs confirmation the termite system meets AS 3660.1. Once installation is finished we assemble an installation certificate that names the products and protected areas, and fit a durable notice inside the meter box, timed so both documents are ready for a strata or building certifier to lodge.

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.

Neutral Bay questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. Any new building work on termite-prone land needs a compliant system under the National Construction Code, and Neutral Bay's apartment renovations and podium slabs are no exception regardless of how many storeys are involved. We work from the plumbing and service drawings to plan the collar layout before the pour rather than after.
It affects drainage and ventilation detailing more than the products used. Basement and lower-level ground near the harbour tends to hold moisture longer, so we pay particular attention to that alongside the standard collars, membrane and perimeter installed to AS 3660.1 on every job we quote in the suburb.
Yes. Shared laundries and bin enclosures in older walk-up blocks are commonly where termite and other pest activity is noticed first, since they hold moisture and are disturbed less often than living areas. We inspect those spaces closely before recommending a system for any renovation or extension work on the building.
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.
