Northern Beaches · AS 3660.1
Termite barriers fitted before the pour on Church Point builds squeezed between Pittwater, McCarrs Creek and Ku-ring-gai Chase National Park, a short walk from the ferry wharf to Scotland Island.
Quick answer
A new home or rebuild at Church Point does need a compliant termite management system before it can be occupied. Northern Beaches Council certifies builds here, and because the area is termite-prone the NCC requires a system meeting AS 3660.1. Collars go on before the slab or footing is poured, and we prepare the meter box notice and installer's certificate for the council afterwards.
Termite barriers in Church Point
Church Point is a small waterside suburb of about 0.7 square kilometres, roughly 24.7 km north of the Sydney CBD and part of Northern Beaches Council. Pittwater Road ends here, and the suburb is bounded by Pittwater, McCarrs Creek and Ku-ring-gai Chase National Park. The ferry wharf is the link to Scotland Island, Lovett Bay and Elvina Bay, and a historic Wesleyan chapel built in 1872 still stands as a reminder of how long the settlement has been here. With water on two sides and national park behind, there is very little vacant land left, so new work is almost always a rebuild, an extension or a boatshed replacement on an existing waterside block, and every one still needs a termite management system signed off.
Homes near the creek and Pittwater sit on soil that stays damp for long stretches of the year, exactly the kind of ground subterranean termites use to travel undetected toward a slab or footing. Ku-ring-gai Chase National Park behind the suburb adds a steady source of activity moving in from established bushland, and many properties are built on slopes with retaining walls and decks constructed to make the most of the water views. Boat storage areas and jetties add more timber close to the waterline, which is worth factoring into any barrier plan. All of that means a Church Point build needs the perimeter and any retaining wall junctions detailed properly before the concrete goes in, not worked around afterwards.

Local conditions
Three features of Church Point's site, water on two sides and bush behind, shape how a barrier is detailed here.
Blocks close to McCarrs Creek and the Pittwater foreshore hold moisture in the soil well after rain, giving a subterranean colony a much easier run at a new slab than dry ground would. We usually recommend a continuous physical barrier on these blocks rather than soil treatment alone.
With national park forming the suburb's inland boundary, termites forage from established bushland toward the nearest structure on almost every Church Point block. The perimeter has to be treated as a full run around the building rather than a partial strip facing the street.
Many properties here are built on slopes with retaining walls and decks constructed to capture the water views, and each step-down or wall junction is a place a rushed barrier can be interrupted. We draw those details before work starts rather than improvising on site.
What we install here
Church Point work is almost entirely rebuilds, extensions and boatshed or jetty-adjacent construction on established waterside blocks, since there is virtually no vacant land left to build on. Piers and a suspended floor are the usual answer wherever a block drops toward the water, and the flatter pockets closer to Pittwater Road are about the only spots left where a conventional slab makes sense. Because access can be tight on these narrow streets, we plan collars and under-slab work around your plumber's rough-in and the builder's actual site conditions, and every job is costed as one fixed written quote before we book a visit.
Local knowledge
Our Church Point jobs cluster near the ferry wharf and the water frontage that links to Scotland Island, Lovett Bay and Elvina Bay, where boat storage and jetty timber add moisture close to the building line. McCarrs Creek Road Reserve, a short distance inland, and Katandra Bushland Sanctuary further along Ku-ring-gai Chase National Park both hold established termite activity that moves toward nearby homes, so we treat retaining walls, decks and sub-floors as carefully as the visible slab edge on these blocks.
Northern Beaches Council certifies Church Point builds, and its requirements match what every NSW certifier expects before releasing an Occupation Certificate. A weatherproof notice goes inside the meter box recording the system fitted, and a signed installation certificate confirms which products were applied, who carried out the work and where on the property the protection runs. On sloping, waterside blocks we also record any retaining wall or suspended floor detailing on that certificate, since the council checks it against the engineering drawings.

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.

Church Point questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes, blocks close to Pittwater or McCarrs Creek generally keep their sub-floor timber and slab joints damp for longer than a dry inland block, so we lean toward a continuous physical barrier rather than relying on soil treatment, which can need more frequent top-ups in consistently wet ground. Retaining walls and decks built for the water views also add junctions that need to be detailed carefully before the concrete goes in.
A termite management system under the NCC applies to habitable building elements, so a boatshed used purely for storage generally falls outside that requirement, but timber jetties and boatsheds near the water are still worth inspecting, since they can host activity close to the main house. We are happy to check these structures while we are on site for the main build.
Very little. Almost all of our work here is a rebuild, an extension or a replacement of an existing waterside structure rather than a build on vacant land, since Church Point is bounded by Pittwater, McCarrs Creek and Ku-ring-gai Chase National Park on almost every side. Whatever the project, the same termite management system and paperwork apply before Northern Beaches Council will sign off.
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.
