Why it matters
You only get one chance to protect what’s under the slab
Subterranean termites are active right across Sydney, and they don’t come in through the front door. They come up from the soil, through the gaps around plumbing pipes, cracks in the slab and the joint at the slab edge, then travel inside walls where nobody sees them.
Once the concrete is down, those entry points are sealed in forever. Protecting them during the build is the cheapest and most complete protection a home will ever have, and damage from termites is usually excluded from home insurance.

- Every pipe penetration sealed
- No hold-ups at the pour inspection

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.
01
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.

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.

Most of the Sydney builds we work on use a combination: physical collars on every penetration plus a physical or chemical perimeter.

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

Termite barrier questions, answered
Can't see your question here? Call us and talk to a licensed technician.
Does a new home in Sydney need a termite barrier?
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 will ask for the installation certificate and durable notice before the Occupation Certificate is issued.
When should I book the barrier installer?
As soon as you have a rough slab date. Collars and under-slab systems go in after the plumber has set out the services and before the concrete is poured, so we lock our visit in around your plumber and concreter.
How much does a pre-construction termite barrier cost?
The price depends on the slab area, perimeter length, number of pipe penetrations, the system you choose, site complexity and how many visits the build needs. Send us your plans and we will return a fixed written quote that covers every stage. Quoting is free.
Is a physical or chemical barrier better?
Both can comply with AS 3660.1. Physical systems need no chemical top-ups and are designed to last as long as the slab while they stay intact. Chemical soil barriers can cost less up front and can be recharged, especially when a reticulation system is laid. Many Sydney builds combine physical collars with a perimeter system.
What paperwork will my certifier get?
A durable notice fixed in the meter box, an installation certificate listing the system, products, areas protected and our licence details, product information, and maintenance and inspection advice for the owner.
Will a barrier make the house termite-proof?
No system makes a building termite-proof. A compliant barrier stops termites getting in unseen and forces any activity out into the open, where an inspection can pick it up. That is why a timber pest inspection at least every 12 months is recommended after handover.
How long does a termite barrier last?
Physical barriers are designed to last the life of the slab as long as they are not damaged or covered. A chemical soil barrier lasts as long as the product label and soil conditions allow, and a reticulation system lets it be recharged without lifting paving.
Do you do extensions, granny flats and duplexes?
Yes. We install systems for extensions, secondary dwellings, duplexes, townhouses and multi-unit projects, and we tie new work into the existing building's protection where that is possible.
Our slab is already poured. Is it too late?
You can no longer protect under the slab or around the pipes directly, but the building can still be protected with a post-construction system such as a trenched and treated chemical perimeter or in-ground baiting. It usually costs more and covers less, so it is always better to book before the pour.
Do you work with volume builders and developers?
Yes. Builders and developers get consistent pricing across lots, one point of contact, scheduling around each site's program and a full document set for every dwelling.
