Northern Beaches · AS 3660.1
Full-perimeter barrier work for Elanora Heights 2101 builds on the ridge above Narrabeen Lagoon, where bushland runs through to Ku-ring-gai Chase and Garigal national parks.
Quick answer
Yes. Because Elanora Heights borders extensive bushland known to carry termite activity, a termite management system is compulsory for any new home built there, under national building rules. The fit-out has to meet AS 3660.1 before the slab goes down. Two pieces of paperwork follow: a durable notice lodged in the meter box, and an installation certificate your certifier requires before signing off the Occupation Certificate.
Termite barriers in Elanora Heights
Elanora Heights sits on high ground above Narrabeen, in postcode 2101 about 19.7 km north of the CBD within Northern Beaches Council, with homes looking out over Narrabeen Lagoon and the Tasman Sea. The suburb began as an estate in 1929 and still carries some of the largest home sites in the old Pittwater area, with the Elanora Country Club and Monash golf courses among its few non-residential landmarks. New building here runs from full house rebuilds on larger established blocks to newer homes on the streets closest to Ingleside.
Bushland connects Elanora Heights through to Ku-ring-gai Chase and Garigal national parks, and that link runs right up to the back fences on many streets. Subterranean termites forage along that bush corridor the same way they would from any large reserve, and a big home with multiple levels, decks and a garage gives a barrier more ground to cover than a simple single-storey slab. Getting the collars and perimeter right before the pour matters more on a block like this than almost anywhere else on the Beaches, and it is far harder to correct once the framing and cladding are up.

Local conditions
Three things about Elanora Heights change how a barrier gets designed here.
The link through to Ku-ring-gai Chase and Garigal national parks means termite colonies have an unbroken run of native bushland right up to many back fences. Full perimeter coverage is standard here, not an upgrade.
Elanora Heights holds some of the biggest blocks in the old Pittwater area, and homes built on them often span multiple levels with decks and garages. More building perimeter and more penetrations mean more collars to place correctly.
Elanora Country Club and Monash golf courses keep large areas of irrigated turf and water hazards nearby, adding another source of moist ground that can support termite foraging close to residential streets on top of the bushland pressure from the national parks.
What we install here
In Elanora Heights we install full perimeter systems, under-slab membrane and collars across new home builds and full rebuilds on larger blocks, matched to suspended floors and split levels as often as a straightforward slab. We work off the plans to price the whole job in one fixed quote, then attend in stages around the builder's program so the barrier is complete before framing starts, with particular care taken on any side of the block facing bushland.
Local knowledge
Koorangi Reserve sits close to many Elanora Heights streets, with Monash Country Club a short distance further on. Blocks nearest the bush corridor towards Ku-ring-gai Chase and Garigal national parks get the fullest perimeter treatment, while those closer to either golf course need the slab edge and any water-facing side checked carefully for damp ground and irrigation run-off close to the foundation.
Northern Beaches Council is responsible for certifying new builds and rebuilds in Elanora Heights. Before the Occupation Certificate is released, its certifiers ask to see a durable notice fixed in the meter box and a matching installation certificate. We supply both as soon as the barrier work on site is complete, together with the relevant product data sheets for your file.

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.

+61 450 515 215It means we treat the full perimeter as standard rather than an optional extra, since colonies along the Ku-ring-gai Chase and Garigal corridor forage in from established bushland. We also pay close attention to any retaining walls or step-downs where the block follows the slope, since those junctions are where a barrier is most likely to be let down.
More building perimeter and more service penetrations mean more collars and a longer run of membrane or physical barrier to install correctly. We plan the layout from the full set of plans so nothing on a lower deck or garage slab is missed, and we price the whole scope in one quote before work begins.
Yes. Rebuild sites on established blocks often have decades of garden growth and old timber in the soil, so we assess what the site is carrying and recommend soil treatment alongside the physical barrier where it is warranted, in addition to the standard collars and perimeter fitted before the new slab or footings are poured.
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.
