Eastern Suburbs · AS 3660.1
Perimeter barriers and under-slab systems fitted to Phillip Bay rebuilds, installed before the pour on villa, cottage and low-rise flat sites wrapped around Yarra Bay on Botany Bay.
Quick answer
Yes. A rebuilt villa, cottage or flat in Phillip Bay still 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 the City of Randwick certifier are both needed before the Occupation Certificate is issued.
Termite barriers in Phillip Bay
Phillip Bay is one of the smallest suburbs in the City of Randwick, about 12.3 km south of the CBD in postcode 2036. It wraps around Yarra Bay on the northern shore of Botany Bay, where HMS Supply anchored in January 1788, and housing is a mix of villas, cottages, townhouses and blocks of flats up to three storeys. Yarra Bay House, built in 1903 for cable station workers, and the Yarra Bay Sailing Club are local landmarks. Given the size of the suburb, our work here is almost entirely rebuilds and renovations on established blocks close to the water.
Sitting directly on the Yarra Bay foreshore means Phillip Bay properties take salt spray and sea breezes that keep timber and sub-floor areas damper than an equivalent block further inland. Low-rise flats and villas here often share walls and roof spaces, so a barrier needs to account for how pests and moisture move between adjoining dwellings, not just what happens under one slab. Older cottages and the century-old buildings like Yarra Bay House also carry timber that has had a long time to be exposed to that same coastal dampness.

Local conditions
Three things shape termite risk in Phillip Bay, tied to its position on the Yarra Bay foreshore.
Sitting directly on Botany Bay's northern shore means Phillip Bay properties take salt spray and sea breezes that keep sub-floor areas and timber damper than an inland block. That moisture is exactly what draws subterranean termites toward a new slab, so drainage and the slab edge get extra attention here.
With low-rise flats and villas making up a large share of Phillip Bay's housing, many properties share walls or roof spaces with a neighbour. We detail the barrier with that shared structure in mind, since a colony active in one dwelling can sit right against the footings of the next.
Buildings like Yarra Bay House, built in 1903, and the suburb's older cottages have had well over a century of exposure to coastal moisture. Rebuilds or extensions near these heritage buildings need soil treatment and the under-slab system checked as seriously as the perimeter itself.
What we install here
We work on Phillip Bay villa and cottage rebuilds, renovations to low-rise flats, and the occasional extension near Yarra Bay House and the older foreshore streets. Waffle pod slabs are common on the more recent builds, while older sites often need a careful check of the existing sub-floor before any new work is detailed. You get one fixed written quote from the plans covering every stage, and we attend around your builder's program so the barrier never holds up the pour.
Local knowledge
Most of our Phillip Bay work sits near Yarra Recreation Reserve and Chifley Sports Reserve, where irrigated grounds and shared bin areas keep the ground nearby damper for longer. Being such a small suburb wrapped around Yarra Bay, almost every property we work on is within a short walk of the foreshore, so salt air and coastal moisture factor into nearly every job.
The City of Randwick wants a durable notice for the meter box and a signed certificate from the installer, listing the products, the coverage and the licence, before it will grant an Occupation Certificate for a Phillip Bay rebuild. We have both ready the moment our stage of the work is finished, whatever the age of the property.

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.

Phillip Bay questions

+61 450 515 215Yes. Salt spray and sea breezes off Botany Bay keep sub-floor areas and timber damper than an inland block, and that moisture makes it easier for subterranean termites to move toward a slab, so we give drainage and the slab edge closer attention on Phillip Bay properties than we would further from the water.
The system is the same NCC-compliant barrier, but we detail it with the shared structure in mind. Activity in one villa or flat can sit right against a neighbouring dwelling's footings, so we check what protection, if any, the adjoining property has before finalising the plan for new work. That check is standard practice on any shared-wall property before we finalise a quote.
Older coastal buildings that have had over a century of exposure to salt air and moisture often need a careful check of the existing sub-floor and timber before new work is detailed. We treat soil preparation and the under-slab system as seriously as the perimeter on rebuilds near these older structures.
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.
