OVERVIEW
Pre-Construction Termite Barriers Done Right the First Time
Termite damage is generally not covered by home insurance, and Sydney is a high-risk area for subterranean termites. The cheapest and most reliable time to protect a building is before the slab is poured, while every pipe penetration and slab edge is still open.
Elite installs termite management systems for new homes, extensions, granny flats, duplexes and multi-unit developments to Australian Standard AS 3660.1. The National Construction Code (NCC) requires a termite management system for new homes and outbuildings in termite-risk areas, and AS 3660.1 is how it's done. We work to your builder's program, install each stage at the right time, and supply the durable notice and installation certificate for your certifier.
Builders, developers and owner-builders get a fixed quote from their plans, a technician who turns up when the site is ready, and paperwork that doesn't hold up the occupation certificate.
- Fixed quote from your plans
- Installed stage by stage to your build program
- Physical, chemical and combination systems
- Durable notice and certificate for the certifier
SYSTEMS WE INSTALL
Termite Barrier Systems We Install
Photos from our own Sydney installations, not stock images. We recommend the right mix for your slab design, site and budget.
Full Under-Slab Membrane
A termite-resistant physical membrane laid across the prepared ground before the pour, protecting the whole footprint of the slab.
Penetration Collars
Collars sealed to every plumbing pipe, conduit and service that passes through the slab. These are the most common hidden entry points for termites.
Perimeter & Slab Edge Barrier
A physical barrier around the slab edge and into the wall cavity, which stops termites building concealed tunnels up the outside of the slab.
Chemical Soil Barrier & Reticulation
APVMA-registered termiticide applied to the soil, with the option of a reticulation pipe network so the barrier can be recharged later without digging.
Suspended Floors & Piers
Protection for bearers, piers and suspended timber floors on sloping or elevated sites.
Retaining Walls & Complex Sites
Detailing against retaining walls, sandstone excavation, step-downs and cut-and-fill sites common across Sydney.
WHY DURING THE BUILD
Why Install During Construction
Once the slab is poured, the areas termites use most are sealed away for good.
A Fraction of the Cost
A pre-construction barrier costs far less than a retrofitted system or repairs to termite damage later.
Required by the NCC
New homes (Class 1) and outbuildings (Class 10) with termite-susceptible primary building elements need a compliant termite management system.
Hidden Entry Points Sealed
Pipe penetrations and slab joints can only be fully protected before concrete covers them.
Whole-Footprint Protection
An under-slab system protects areas no post-construction treatment can reach.
No Occupation Certificate Delays
Your certifier needs the installation certificate and durable notice before issuing the Occupation Certificate.
Resale Confidence
Documented, compliant termite protection reassures buyers, building inspectors and lenders.

COMPARE SYSTEMS
Physical vs Chemical Termite Barriers
Both approaches can comply with AS 3660.1. Many Sydney builds use a combination.
| System | How it works | Durability & upkeep | Best suited to |
|---|---|---|---|
| Physical membrane, mesh or graded stone | A termite-resistant layer (sheet, stainless mesh or graded stone particles) that termites can't chew through, laid under the slab or at the perimeter | Designed to last as long as the slab if it isn't disturbed. No chemical top-ups. | Slab-on-ground homes and owners who want a non-chemical option |
| Penetration collars | Physical collars sealed around every pipe and conduit through the slab | Long-lasting when installed correctly before the pour | Every slab. Usually combined with a perimeter system. |
| Chemical soil barrier | A treated zone of termiticide in the soil under and around the building | Service life depends on the product label and soil conditions. It can be re-applied. | Budget-conscious builds and some complex sites |
| Reticulation system | A pipe network laid before paving so termiticide can be pumped back into the soil | Rechargeable for the life of the building without digging up paths | Homes surrounded by paving or landscaping |
| Baiting (post-construction) | In-ground monitoring stations that eliminate the colony | Stations need regular servicing | Existing homes, see termite control |
INSTALLATION STAGES
How a Pre-Construction Barrier Is Installed
Termite barriers are installed in stages that follow the build, not in a single visit.
01
Plan Review & Fixed Quote
Send us your plans and slab details. We recommend a system and give you a fixed price for every stage.
02
Stage 1: Before the Pour
Penetration collars fitted to all services, and an under-slab membrane or chemical treatment installed once the site is prepared.
03
Stage 2: Slab Edge & Cavity
Perimeter and cavity barriers installed as the brickwork or cladding goes up, so there is no gap at the slab edge.
04
Stage 3: Final Perimeter
Where specified, a chemical perimeter or reticulation system is completed around the finished building before paving and landscaping.
05
Durable Notice & Certificate
A durable notice in the meter box records the system. The installation certificate goes to the builder and certifier.
06
Handover Advice
The owner receives maintenance advice and a recommended inspection schedule to keep the system effective.
PAPERWORK
Documents You Receive at Handover
| Document | What it is | Who needs it |

FOR BUILDERS
For Builders, Developers & Owner-Builders
Coordinating with your trades
We schedule around the plumber's set-out and the concreter's pour. Tell us when services are in and we will confirm the collar installation before the pour inspection.
- Penetration collars before the pour
- Slab edge and cavity barrier as walls go up
- Perimeter completed before paving
Multi-unit and repeat work
Developers and volume builders get consistent pricing, a single point of contact and documentation for every lot or dwelling.
Avoiding certification delays
Missing durable notices or unclear installation records are a common reason for occupation certificate delays. We supply everything together so the certifier has what they need.
AFTER HANDOVER
How to Keep Your Termite Barrier Effective
A barrier only works if it stays intact and visible. Homeowners should follow these points for the life of the building.
- Keep at least 75 mm of the slab edge exposed as the inspection zone. Don't cover it with soil, mulch or paving.
- Don't build garden beds or stack timber against the house
- Keep weep holes clear and free of render and debris
- Fix leaking taps, downpipes and hot water units near the house
- Tell your builder or installer before drilling through the slab
- Check that new pipes or extensions are protected too
- Have a timber pest inspection at least every 12 months
- Keep the durable notice and installation certificate with your property records
PRICING FACTORS
What Affects the Cost of a Termite Barrier
| Factor | Why it matters |
|---|---|
| Slab area & perimeter length | Larger footprints need more membrane, more perimeter protection and more labour |
| System type | Full under-slab physical systems, perimeter-only systems and chemical or reticulation options are priced differently |
| Number of penetrations | Every plumbing and electrical penetration through the slab needs a collar |
| Site complexity | Retaining walls, step-downs, sandstone excavation and suspended floors add detailing |
| Number of site visits | Staged installations follow the build program. Multi-dwelling sites may be combined. |

SYDNEY NEW BUILDS
Termite Protection for Sydney New Builds
Sydney's subterranean termites, including the highly destructive Coptotermes species, are active across the whole metropolitan area, from new estates in Box Hill, Oran Park and Marsden Park to knockdown-rebuilds in the Inner West, St George and the Sutherland Shire. Bushland edges, sandstone excavation and heavily landscaped blocks all make the right barrier design more important.
Already built? We protect existing homes with termite treatment and baiting systems, and recommend a timber pest inspection every 12 months.

FAQ
Pre-Construction Termite Barriers Questions, Answered
Everything you need to know before you book. Still unsure? Call us — we're happy to help.
Get a Free QuoteIs a termite barrier required for a new home in Sydney?
Generally yes. The National Construction Code requires a termite management system for new homes and outbuildings in termite-risk areas where primary building elements, such as timber framing, can be damaged by termites. It is installed to AS 3660.1, and your certifier asks for the installation certificate and durable notice before issuing the Occupation Certificate.
How much does a pre-construction termite barrier cost?
Pricing depends on the slab area, the system chosen, the number of pipe penetrations, perimeter length and how many site visits the build needs. Send us your plans and we will give you a fixed written quote covering every stage.
When should I book the termite barrier installer?
Book as soon as your slab date is roughly known. Penetration collars and under-slab membranes must go in after the plumber sets out the services and before the concrete pour, so the timing has to be coordinated with your builder.
Physical or chemical termite barrier: which is better?
Both can comply with AS 3660.1. Physical systems need no chemical top-ups and last as long as the slab if they aren't disturbed. Chemical systems can cost less up front and can be recharged, especially with reticulation. Many builds combine physical penetration collars with a perimeter system.
What is a durable notice?
A durable notice is a permanent label, usually fixed in the meter box, that AS 3660.1 requires. It records the type of termite management system installed, the date of installation, the installer, and the inspection and maintenance recommendations for the life of the building.
Do termite barriers stop termites completely?
No barrier makes a building termite-proof. A compliant barrier stops concealed entry and forces termites into the open, where regular inspections can find them. That is why inspections at least every 12 months are recommended after handover.
How long does a pre-construction termite barrier last?
Physical barriers are designed to last as long as the slab while they stay intact. The service life of a chemical soil barrier depends on the product and site conditions, and reticulation systems let it be topped up without disturbing paving.
What documents do I get for the certifier?
You receive the durable notice fixed on site, an installation certificate listing the system, product and installer licence, and maintenance and inspection advice to pass on to the owner.
Can you install barriers for extensions, granny flats and duplexes?
Yes. We install pre-construction systems for extensions, secondary dwellings, duplexes, townhouses and multi-unit developments, and join new work to existing protection where possible.
What happens if the slab is poured before the barrier goes in?
The under-slab area and pipe penetrations can no longer be protected directly, so the only options are post-construction systems: a chemical soil barrier trenched and injected around the perimeter, or in-ground baiting. That usually costs more and protects less, so book before the pour.
