Creek and river reserves
Batten Creek and Stringybark reserves bring bushland into the suburb, with the Lane Cove River on the western boundary. Blocks nearest those margins get continuous perimeter treatment.
Quick answer
Yes, new buildings at Lane Cove North with susceptible elements need a termite management system under the NCC, installed to AS 3660.1. Collars and under-slab work go in before concrete. Depending on which side of Mowbray Road you are, Lane Cove or Willoughby certifies, and each needs the certificate and durable notice.
Termite barriers in Lane Cove North
Why Lane Cove North builds need the barrier in before the pour
Lane Cove North sits about 8 km north-west of the city and is split between Lane Cove Council and the City of Willoughby, with Mowbray Road as the boundary. Apartments dominate, making up around seven in ten dwellings, with separate and semi-detached houses accounting for the rest. The Pacific Highway runs along the east, Epping Road forms the southern edge, Chatswood Golf Course sits to the north and the Lane Cove River forms the western boundary, with Batten Creek Reserve and Stringybark Reserve bringing bushland into the suburb.
The reserves and the river are the reason a barrier here is designed rather than assumed. Bushland holds fallen timber and damp soil that sustain subterranean colonies, and houses and ground-floor units nearest those margins sit within easy foraging reach. On the apartment side, a single slab can carry dozens of hydraulic penetrations, each one a potential entry point unless it is collared before the pour. Both situations come down to sealing penetrations, the edge and the joints while the concrete is still to come.

Local conditions
What makes Lane Cove North blocks a termite risk
Three local conditions drive barrier work here.
Apartment-dominated construction
With roughly seven in ten dwellings being units, most slabs here are multi-dwelling. Collar counts and coordination with the hydraulic trade shape the program far more than floor area.
Two certifying councils
Mowbray Road splits the suburb between Lane Cove and Willoughby, so we confirm which authority holds the approval before preparing the completion documentation.
What we install here
Building in Lane Cove North
Work here is mostly apartment and townhouse slabs, plus house rebuilds and secondary dwellings on the remaining detached blocks. We collar every penetration, install the under-slab component or treated zone specified, and complete the perimeter and cavity barrier as the structure rises. Sloping sites near the reserves often include piers or suspended floors, which are protected as part of the system. Pricing is fixed from the plans with each stage identified and booked to the builder's program.
- Under-slab membraneA termite-resistant sheet laid across the prepared ground before the pour.
- Penetration collarsCollars sealed to every pipe and conduit that comes up through the slab.
- Perimeter & slab edgeA barrier at the slab edge and into the cavity, so nothing can track up hidden.
- Chemical soil barrierAn APVMA-registered treated zone in the soil under and around the building.
- ReticulationA pipe network laid before paving so the treated zone can be topped up later.
- Piers & suspended floorsProtection for bearers, piers and suspended timber floors on sloping blocks.
Local knowledge
Around Lane Cove North
Jobs sit near St Peter's Green, a few hundred metres from the centre, and run west towards Batten Reserve and the river margin about 700 metres away, with Chatswood Golf Course on the northern edge. Blocks adjoining reserve country or the golf course boundary get the most attention at the perimeter, since bushland timber and irrigated ground both keep foraging pressure up against those fences.
Because Mowbray Road divides Lane Cove North between Lane Cove Council and the City of Willoughby, the certifier depends on your address. The evidence required is identical in both: a certificate covering products, protected areas and installer details, and a durable notice fixed in the meter box recording the system with its inspection recommendation, both in place before the Occupation Certificate is issued.

Systems we install
The right barrier for your slab and your site
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.
01Under-slab membrane
A termite-resistant sheet laid over the whole prepared footprint before concreting, so termites can't come up through the slab anywhere.
02Penetration collars
A sealed collar on every pipe, conduit and service that passes through the slab. These gaps are the most common hidden way in.
03Slab edge & cavity barrier
Protection at the slab edge and into the wall cavity, which stops termites building hidden tunnels up the outside of the slab.
04Chemical soil barrier & reticulation
An APVMA-registered termiticide zone in the soil, with an optional pipe network under paving so it can be recharged later without digging.
05Suspended floors & piers
Barriers for bearers, piers and raised timber floors on sloping or elevated blocks, where there's no slab to protect.
06Retaining walls & tricky sites
Detailing for sandstone cuts, block retaining walls, step-downs and cut-and-fill sites, which are common across Sydney.
Why during construction
Do it now, or pay more to do less later
A retrofit can only treat around a finished house. A pre-construction system protects the parts nobody will ever be able to reach again.
Costs far less
A barrier put in during the build costs a fraction of a post-construction system, and far less than repairing termite damage.
Meets the NCC
New houses (Class 1) and outbuildings (Class 10) with termite-susceptible framing need a compliant termite management system.
Hidden gaps sealed
Pipe penetrations and slab joints can only be fully protected while they're still open, before the concrete goes in.
The whole footprint
An under-slab system covers ground that no treatment from outside the finished house can ever reach.
No OC delays
Your certifier needs the certificate and durable notice before issuing the Occupation Certificate. We supply both together.
Easier to sell
Documented, compliant protection gives buyers, building inspectors and lenders confidence when the home is sold.
Installation stages
Installed in stages that follow your build
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.
Step 01Design / DA
Plans & fixed quote
Send your plans and slab details. We recommend a system and give you one fixed price that covers every stage.
Step 02Before the pour
Collars & under-slab
Collars go on every service once the plumber has set out, then the membrane or soil treatment is installed across the prepared site.
Step 03Walls going up
Slab edge & cavity
Perimeter and cavity protection is fitted as the brickwork or cladding goes up, so there's no unprotected gap at the slab edge.
Step 04Before landscaping
Final perimeter
Where it's specified, the chemical perimeter or reticulation system is completed around the building before paths and gardens go in.
Step 05Pre-OC
Notice & certificate
A durable notice goes in the meter box, and the installation certificate goes to your builder and certifier.
Step 06Handover
Owner advice
The owner gets simple care instructions and an inspection schedule so the system keeps doing its job for years.

Pricing
What sets the price of a barrier
Every build is different, so we don't guess. We price from your plans and give you one fixed written quote. Quoting is free.
- 01Slab area & perimeterBigger footprints need more material, more edge protection and more labour.
- 02System typeFull under-slab, perimeter-only, chemical and reticulation options are all priced differently.
- 03Number of penetrationsEach plumbing and electrical service through the slab needs its own collar.
- 04Site complexityRetaining walls, step-downs, sandstone and suspended floors add detailing.
- 05Number of visitsStaged installs follow your program. Multi-dwelling sites can often be combined.
- 06Site accessTight blocks, steep driveways and limited street frontage slow the set-out and add time on site.
After handover
Keeping the barrier working
A barrier only works while it stays intact and visible. Pass these on to the owner.
- Keep at least 75 mm of the slab edge exposed. Don't cover it with soil, mulch or paving.
- No garden beds or stacked timber against the house
- Keep weep holes clear of render and debris
- Fix leaking taps, downpipes and hot water units near the walls
- Ask the installer before drilling through the slab or adding pipes
- Book a timber pest inspection at least every 12 months

Lane Cove North questions
Answered
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Which council certifies my Lane Cove North project?
Either Lane Cove Council or the City of Willoughby, depending on which side of Mowbray Road the property sits. We check that when quoting so the completion paperwork matches your approval. The installation standard does not change, since AS 3660.1 and the NCC requirement apply across both council areas.
Does a ground-floor unit near the reserves need special attention?
The building as a whole is protected by the system installed at slab stage, and blocks near Batten Creek or Stringybark reserves get the fullest perimeter treatment because bushland timber supports colonies close by. Keeping the slab edge visible after landscaping is what preserves the value of that work over time.
How do you handle a large apartment slab?
By working from the hydraulic set-out. Every penetration is collared in one coordinated pass before the pour inspection, rather than piecemeal, and the perimeter is completed as the structure rises. Documentation is prepared so the certifier can match the installed system against the approval covering the whole building.
Does a new home need a termite barrier in NSW?
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.
What does a pre-construction barrier cost?
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.
