Northern Beaches · AS 3660.1
Barrier design for semi-rural Ingleside 2101, where new houses, granny flats and outbuildings sit on bushland blocks between Mona Vale Road and Ku-ring-gai Chase National Park.
Quick answer
A new dwelling at Ingleside needs a termite management system. The NCC calls for one in termite-prone areas, and it is installed to AS 3660.1 before and during the slab stage. Collars and under-slab work go in once services are set out. Your certifier receives the installation certificate and durable notice ahead of the Occupation Certificate.
Termite barriers in Ingleside
Ingleside occupies the elevated country west of Mona Vale, roughly 21 km north of the city and inside Northern Beaches Council. It is a semi-rural pocket: bushland, larger rural-residential holdings and pockets of newer housing, with the Baha'i Temple standing on the ridge since 1961. Building here tends to mean a house plus outbuildings, a shed, a studio or a stable, often replacing structures that have stood on the block for decades. Each of those slabs counts as its own job, and each one is far easier to protect while the site is open than after the concrete has gone down.
What sets Ingleside apart is how close the bush stays to the building line. The suburb borders Ku-ring-gai Chase National Park and its blocks hold standing timber, stumps and deep litter, all of which support established subterranean colonies well before a builder arrives. Termites move through soil and arrive at a new slab hunting for the same weaknesses: an unsealed pipe penetration, an exposed edge, or a joint they can follow upward unseen. Sealing those routes has to happen before the pour, which is why we price the barrier from your plans rather than guessing on the day.

Local conditions
Three conditions shape how a barrier is detailed on an Ingleside block.
Ku-ring-gai Chase country wraps the plateau, and Katandra Bushland Sanctuary sits roughly 2 km from the centre. Colonies foraging out of that bush reach building pads through soil, so perimeters here are continuous rather than partial.
Acreage projects rarely stop at the house. Sheds, studios, garages and stables each need their own collars and edge treatment, and pricing them together avoids a second mobilisation later in the build.
Ridge blocks are benched to get a level pad, leaving batters, retaining and step-downs. Those junctions are where barriers are most often compromised, so the detail gets drawn before anyone orders concrete.
What we install here
Ingleside projects usually involve a new home or replacement dwelling, a secondary dwelling, or a large outbuilding on an established holding. We install physical collars on every service, an under-slab membrane or treated zone to suit the design, and a continuous perimeter where the pad meets fill or retaining. Suspended floors and pier systems are common on the fall, and they are protected too. One written price covers each stage, and visits are booked around your plumber and concreter so the pour date holds.
Local knowledge
Our Ingleside work runs along the ridge roads near the Baha'i Temple, out towards Katandra Bushland Sanctuary about 2 km from the centre, and around the streets edging Monash Country Club less than a kilometre away. Blocks that back onto reserve or park country get the most attention at the perimeter and at every retaining junction, while irrigated turf next door is a reminder that soil moisture near a slab edge deserves the same care.
Northern Beaches Council covers Ingleside, and the certifier handling your build asks for proof of the termite management system before the Occupation Certificate is issued. Two records do that: a permanent notice mounted in the meter box that sets out the system, its installation date, the installer and the inspection advice, plus a certificate confirming what went in and where. Product data and the owner's maintenance notes are handed over at the same time.

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.
Consistent pricing across lots, one point of contact and a full document set for every dwelling.
Missing durable notices and unclear install records are a common reason Occupation Certificates get held up. We hand everything over together so your certifier has it all in one go.
Paperwork
A complete document set for the builder, the certifier and every future owner of the property.
A permanent notice in the meter box showing the system, install date, installer, any chemical's life expectancy and inspection advice.
For: certifier, owner, future owners
Written confirmation of the system and products used, the areas protected and our licence details.
For: builder, certifier, owner
Details of the physical system or termiticide installed, including safety data sheets for any chemicals.
For: builder, owner

Ingleside questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215If a structure has primary building elements that termites can damage, it needs a compliant system, and on acreage that usually means the shed, studio or stable as well as the house. We quote each slab separately so you can see what each structure costs, and we schedule them together where the pours are close so there is only one mobilisation to site.
It changes the detailing rather than the standard. Blocks near Ku-ring-gai Chase country carry steady foraging pressure from established bush, so we favour physical collars on every penetration plus a continuous physical perimeter, adding a reticulation line where paving or landscaping will later cover the treated zone and make top-ups difficult.
At the plan stage, before the excavator finishes. Cut-and-fill leaves batters, retaining walls and step-downs that a barrier has to follow, and those junctions are far cheaper to detail on paper than to patch once formwork is up. Send the engineering drawings with the slab plan and the quote will cover them.
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.
