River and reserve margins
With a sixth of the area as public recreation land and the Lane Cove River nearby, timber and damp soil sit close to residential boundaries, so perimeters are run continuously rather than partially.
Quick answer
New buildings at Lane Cove with termite-susceptible elements need a management system under the NCC, installed to AS 3660.1. Collars and under-slab protection precede the pour, the perimeter follows during construction, and Lane Cove Council certifiers require the certificate and durable notice before the Occupation Certificate.
Termite barriers in Lane Cove
Why Lane Cove builds need the barrier in before the pour
Lane Cove is the administrative centre of Lane Cove Council, about 7 km north-west of the city on the northern side of Port Jackson where the Lane Cove River opens out. Most of its residential growth came after the Second World War, and today roughly six in ten dwellings are flats or apartments with about three in ten separate houses. The shopping hub centres on the pedestrian plaza at Burns Bay and Longueville roads, and about 16 per cent of the area is public recreation space, including Burns Bay Park, Pottery Green and Tantallon Oval.
That balance produces two kinds of barrier job. Apartment slabs carry heavy hydraulic runs and need coordination with the hydraulic trade, while post-war house blocks are rebuilt on soil that has been gardened for seventy years. The river and the reserves keep timber and damp ground within foraging distance of both. Whatever the building type, colonies probe the same weaknesses, the penetrations, the slab edge and the joints, and sealing them is only possible while the site is open ahead of the pour.

Local conditions
What makes Lane Cove blocks a termite risk
Three Lane Cove conditions shape the barrier design.
Apartment podium slabs
Medium-density development around the plaza puts dozens of services through one slab. The hydraulic set-out drives the program and collars are completed in a single pass before the pour.
Post-war rebuild blocks
Houses from the 1950s and 60s sit on deeply planted lots. Old stumps and buried timber leave food in the soil, which increases the value of the under-slab component.
What we install here
Building in Lane Cove
In Lane Cove we install for apartment and townhouse slabs near the plaza, replacement houses on established streets, and secondary dwellings at the rear of older blocks. Every penetration is collared, the specified under-slab component goes in, and perimeter and cavity protection follows the structure. Sloping sites with piers or suspended floors are covered too. Each job is quoted as one fixed price with stages itemised, scheduled so the barrier never sits between the plumber and the concrete truck.
- 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
Work sits within a few hundred metres of the plaza and The Village shopping precinct, spreads through the streets near Cameraygal Park, and runs down towards Burns Bay Park and the river. Blocks backing reserve or river country get the fullest perimeter treatment, while the denser sites near the plaza are about penetration counts and fitting the barrier stage into a tight construction program.
Lane Cove Council is the certifying authority here. Before an Occupation Certificate is issued, your certifier needs proof of the termite management system: a certificate identifying the products used, the areas protected and the installing technician, plus a permanent notice in the meter box stating the system, the date it went in and how often the building should be inspected. Both are provided with product data at completion.

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 questions
Answered
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Do apartment buildings in Lane Cove need barrier work?
Where the building includes primary elements that termites can damage, yes. Scale changes the planning rather than the requirement: a podium slab carries a large number of hydraulic penetrations, so collaring is coordinated with the hydraulic contractor and completed in one pass before the pour, with documentation prepared for the development as a whole.
Our Lane Cove block backs onto a reserve. What changes?
The perimeter becomes the priority and runs the full slab rather than the exposed faces only. Reserve country holds mature timber that supports established colonies within easy foraging distance, so junctions at any step-down are detailed carefully and reticulation is worth adding where landscaping will later cover treated soil.
We are rebuilding a 1950s house. Is the old treatment relevant?
Not for compliance. Anything applied when the original house was built is well past its service life, so the new dwelling needs a current system installed to AS 3660.1 with its own certificate and durable notice. What the old block does affect is the soil, since decades of garden material can already be supporting activity.
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.
