Sutherland Shire · AS 3660.1
Perimeter termite barriers installed to AS 3660.1 for the handful of new builds and rebuilds in Maianbar, a village completely surrounded by Royal National Park on the shore of Port Hacking.
Quick answer
Yes, a new home or rebuild in Maianbar needs a termite management system, since the village sits in a termite-prone part of the Sutherland Shire and is entirely surrounded by Royal National Park bushland. The system is installed to AS 3660.1, with collars and under-slab work completed before the pour, and the durable notice plus installation certificate supplied to your certifier before the Occupation Certificate.
Termite barriers in Maianbar
Maianbar is a small village on the southern side of Port Hacking, next to Bundeena, in postcode 2230 about 24 km south of the Sydney CBD, part of the Sutherland Shire and completely surrounded by Royal National Park, which limits development and keeps the village compact. Residents reach it by road through the park or by ferry, and the village has a single shop, a community hall, a Rural Fire Brigade station and a local park, with Rusa deer a familiar sight. Because the village is so tightly bounded, new building work here is almost always a rebuild or renovation on an existing small block.
Homes in Maianbar sit very close together on a small area, with bush on the land side and water in front, and that combination makes termites part of daily life in the village. Subterranean termites forage readily from the surrounding national park through leaf litter, fallen timber and damp estuary soil toward the nearest slab, and houses built close together can share the same pressure from one property to the next. A barrier here has to be sized to the bush on one side and the salt-air moisture on the other, with no room to treat either as a minor factor.

Local conditions
Three conditions make termite pressure in Maianbar higher than in most Sutherland Shire suburbs.
Maianbar sits entirely within Royal National Park, so bushland is the boundary on the land side of every property in the village. That much surrounding bush holds established termite colonies with a short, direct path to any rebuild.
Salt air from the Port Hacking estuary keeps sub-floors and cavities damp across the village, conditions that suit subterranean termites as much as cockroaches and silverfish. We factor that dampness into sub-floor ventilation on every rebuild.
Maianbar's houses sit close together on a small area, which means termite pressure on one property can be a shared concern with the next. We inspect neighbouring boundaries as part of the quote, not just the block being rebuilt.
What we install here
Our Maianbar work is almost always a rebuild or renovation on an existing village block, given how little vacant land remains inside the national park boundary. We install physical or chemical perimeter systems and under-slab membrane suited to bushland and estuary conditions, with particular care at sub-floor ventilation and ground-contact timber. We plan our visit around the drive through the park, and one fixed quote from your plans covers every stage.
Local knowledge
Our Maianbar work sits close to Kara Karook Street Reserve and Maris Park, where bushland edges run directly against several small blocks, and near Maian Bar Beach, where salt air off the estuary keeps sub-floors humid. Because Royal National Park surrounds the whole village, every inspection we do here covers the sub-floor, roof void and any timber touching the ground, regardless of which street the block sits on.
Maianbar is certified through the Sutherland Shire, which requires the same termite documentation as anywhere else in the shire before issuing an Occupation Certificate: a durable notice fixed in the meter box, and an installation certificate naming the products used, the areas protected and the installer's licence. We supply both, with maintenance advice suited to a bushland village with no through traffic.

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

Maianbar questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215It usually means a more thorough physical perimeter rather than a minimal strip, since bushland forms the boundary of every property in the village. We check the specific side of your block facing the park most closely, since that is where pressure is highest. We treat every quote as specific to your actual block.
We plan the visit around the road access through Royal National Park, since that is the only vehicle route to the village. Let us know your preferred access window when you book, and we will schedule collars and perimeter work around your builder's program. We are happy to talk through the specifics once we see your plans.
It can. Houses in Maianbar sit close together, so established termite activity next door is a real consideration, not a formality. We look at the neighbouring structure during the quote and detail the shared boundary accordingly. Reach out early so we can lock in a suitable date. We keep a copy of every certificate on file for later.
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.
