Upper North Shore · AS 3660.1
Full perimeter barriers and under-slab systems installed before the pour on North Turramurra's forested spur, where blocks fall away toward Lovers Jump Creek, Cowan Creek and Ku-ring-gai Chase National Park.
Quick answer
Yes. North Turramurra sits on a bush-fringed spur bordering national park, so new homes and rebuilds need an NCC termite management system installed to AS 3660.1. Collars and any under-slab work go in before the pour. The durable notice for the meter box and an installation certificate for Ku-ring-gai Council are both needed before the Occupation Certificate is issued.
Termite barriers in North Turramurra
North Turramurra became a separate suburb in 1994 and sits on a spur between Lovers Jump Creek and Cowan Creek, about 19 km north of the CBD in postcode 2074 and Ku-ring-gai Council. Heavily forested valleys run down on either side of that spur, with Ku-ring-gai Chase National Park bordering the suburb to the north. Homes tend to be larger houses on generous blocks, and Bobbin Head Road carries a small shopping village through the middle. The suburb also has several aged care facilities and Lady Davidson Private Hospital, so our work here ranges from family home rebuilds to documented commercial servicing.
Living on a spur with forested valleys dropping away on both sides means bushland is close no matter which street you are on. Termites forage from fallen timber and leaf litter in those gullies, and generous blocks with sheds, decks and mature trees give them plenty of places to establish before they ever reach a slab. Getting the perimeter, collars and under-slab membrane right before the pour is the only real way to keep that pressure out of a new home from the start, rather than discovering it years later.

Local conditions
Three things push termite pressure higher on a North Turramurra block than on flatter, more open suburbs.
Lovers Jump Creek and Cowan Creek run through heavily forested valleys either side of the spur, holding established colonies in fallen timber and leaf litter. Blocks anywhere on the spur can back onto that bush, so we run a full perimeter system rather than assuming distance from the creek line is enough protection.
With the national park bordering the suburb to the north, properties on that edge sit against bushland that is never going to be cleared or managed the way a neighbouring yard would be. That makes the perimeter and any retaining junctions on those blocks the most important part of the barrier job.
North Turramurra's generous blocks often carry sheds, timber decks and established gardens that add moisture and timber-to-ground contact well beyond the house footprint. We check those features as part of the barrier plan rather than treating the job as just the slab underneath the house.
What we install here
We work on North Turramurra new homes, knockdown rebuilds and granny flats on generous, bush-adjacent blocks across the suburb, plus documented servicing for the aged care facilities and Lady Davidson Private Hospital where compliance paperwork matters as much as the install. Suspended floors and piers are common where a block falls toward one of the creek valleys, alongside waffle pod slabs on the flatter pads nearer Bobbin Head Road. You get one fixed written quote from the plans, and we attend around your builder's program so the barrier never holds up the pour.
Local knowledge
Most of our North Turramurra work sits close to the bushland running down from the spur toward Lovers Jump Creek and Cowan Creek, near reserves like Terramerragal Reserve and Guiders Park, where the perimeter and any step-down details get the closest attention. Around Pymble Golf Club, irrigated turf keeps some neighbouring blocks damper for longer, which we factor into slab edge checks on properties nearby.
Ku-ring-gai Council is the certifying authority for North Turramurra, and its requirements before an Occupation Certificate are a durable notice fixed inside the meter box and a formal certificate from the installer setting out the products used, the coverage area and the licence number. We finalise both as soon as our stage of the work concludes, including for the aged care and hospital sites we service locally.

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.

North Turramurra questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215They need more attention to the perimeter rather than a different product. Bushland along Ku-ring-gai Chase National Park and the creek valleys either side of the spur holds established colonies that forage toward gardens, so we run a full perimeter system and pay close attention to any retaining wall or step-down near the bush boundary.
Yes. Aged care and healthcare sites need the same documented termite management system as a new home, installed to AS 3660.1, with the paperwork prepared to the standard these facilities require. We work around access and operational hours, and provide the certification the facility needs for its own compliance records.
As soon as you have a rough slab date from the builder. Collars and any under-slab system need to go in after the plumber's rough-in and before the pour, so we lock our visit into that window. On blocks that fall toward a creek valley, let us know early if retaining work is involved.
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.
