Sutherland Shire · AS 3660.1
Perimeter barriers and under-slab systems fitted to Port Hacking's foreshore blocks, installed before the pour on established gardens running down toward the Port Hacking estuary.
Quick answer
Yes. Port Hacking sits on estuary foreshore with pockets of bush nearby, so a new home or rebuild needs an NCC termite management system installed to AS 3660.1. Collars and under-slab work go in before the concrete pour. The durable notice for the meter box and an installation certificate for Sutherland Shire are both needed before the Occupation Certificate is issued.
Termite barriers in Port Hacking
Port Hacking is a small residential suburb on the northern shore of the Port Hacking estuary, in postcode 2229 about 23.7 km south of the CBD, within Sutherland Shire. It shares its name with the estuary itself, with Caringbah South to the north-west, Lilli Pilli to the south-west and Dolans Bay to the north-east. Shiprock Aquatic Reserve, within Burraneer Bay, is close by, and a small commercial strip on Port Hacking Road South has cafes, restaurants and specialty shops. Homes are mainly detached family houses, some with water views, sitting in established gardens across the suburb.
Being on a peninsula between bays means Port Hacking shares the moisture and foreshore conditions of its neighbours, along with pockets of bush scattered through the suburb. That combination brings termites to damp garden timber near the water, and established colonies in the bush pockets forage into nearby gardens through fallen timber and leaf litter. A rebuild here needs the perimeter and under-slab system matched to what the specific block is actually close to, whether that is the estuary foreshore or a patch of remnant bush further from the water.

Local conditions
Three things shape termite risk on a Port Hacking block, tied to the estuary and the bush pockets scattered through the suburb.
Ground near the Port Hacking estuary and its bays holds moisture for longer than blocks further from the water. That dampness makes it easier for subterranean termites to move toward a slab, so we give drainage and the slab edge extra attention on foreshore properties.
Port Hacking has patches of remnant bush scattered through its residential streets, and established colonies in that bush forage into nearby gardens through fallen timber and leaf litter. Blocks near these pockets get a full perimeter system rather than a partial strip.
Many Port Hacking properties sit in gardens that have had decades to develop, with buried timber and mature planting close to the house. Rebuild sites need soil treatment and the under-slab system checked as carefully as the perimeter around the edge.
What we install here
We work on Port Hacking knockdown rebuilds and renovations on established, foreshore-adjacent blocks across the suburb, from the streets near Shiprock Aquatic Reserve to the quieter pockets further from Port Hacking Road South. Suspended floors and piers are common on blocks with water views that fall toward the estuary, alongside waffle pod slabs on more level pads. You get one fixed written quote from the plans covering every stage, and we attend around your plumber's rough-in and the concreter's pour date.
Local knowledge
Most of our Port Hacking work sits near Maris Park and Shiprock Aquatic Reserve, where estuary foreshore conditions shape the slab edge and drainage detailing on nearby rebuilds. Toward Maian Bar Beach across the water, the same estuary air keeps sub-floors damp on properties along that stretch, and we check ground-contact timber closely on those blocks. We check the bush pockets scattered through the suburb just as closely as the foreshore itself.
Sutherland Shire is the certifying authority for Port Hacking, and it holds off on the Occupation Certificate until it has a durable meter-box notice and a certificate from the installer detailing the products, the coverage and the licence held. Both are ready the moment our stage of a Port Hacking rebuild is finished.

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.

+61 450 515 215It changes how carefully we detail drainage and the slab edge. Ground near the estuary and its bays holds moisture for longer than blocks further away, and that dampness makes it easier for subterranean termites to move toward a slab, so foreshore properties get closer attention on these details. We confirm this before pricing any job close to the water.
Yes. Remnant bush scattered through the suburb holds established colonies that forage into nearby gardens, so we run a full perimeter system on blocks near these pockets rather than a partial strip, checking the bush-facing boundary as closely as the rest of the property. We identify these pockets during our initial site visit rather than relying on a general assumption.
As soon as you have a rough slab date from the builder. Collars and any under-slab system need to go in after the plumber's rough-in and before the pour, so we lock our visit into that window. On established, well-gardened blocks, tell us early about any large trees or garden beds being cleared.
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.
