Greater Parramatta & Cumberland · AS 3660.1
Collars and under-slab systems installed to the builder's program across Parramatta's tower construction, from the Church Street light rail corridor to rebuilds on the older streets near the river.
Quick answer
Yes. A new residential building in Parramatta, whether a tower, townhouse or house, needs an NCC termite management system installed to AS 3660.1. Collars and any under-slab work go in before the concrete pour. The durable notice for the meter box and an installation certificate for the City of Parramatta certifier are both required before the Occupation Certificate is issued.
Termite barriers in Parramatta
Parramatta is the administrative seat of the City of Parramatta, in postcode 2150, about 20 km west of the CBD, and is often called Sydney's second CBD for its role as the main commercial and government centre of Greater Western Sydney. Most people here live in apartments, many of them in recently built towers, with fewer houses, townhouses and semis scattered through the older streets. Westfield Parramatta is one of Australia's largest shopping centres, and the suburb is served by three train lines, the L4 light rail, ferries from Parramatta wharf and the future Sydney Metro West, all of which have brought sustained apartment construction.
Old Government House stands within Parramatta Park, an 85-hectare former Governor's Domain beside the river, and St John's Cathedral dates back to 1802, a reminder that Parramatta has been built and rebuilt on this ground for well over two centuries. That mix of dense new tower construction and much older residential streets near the park and river foreshore means a termite barrier here can mean two very different jobs: a basement-level slab with dozens of service penetrations on one site, and a knockdown rebuild on a mature, riverside block on another.

Local conditions
Three things shape termite risk across Parramatta's mix of tower construction and older riverside streets.
With most of Parramatta's housing already in apartments, new towers near the stations and light rail corridor are common, and a single basement-level slab can carry a large number of service penetrations. Collar counts and scheduling around a busy multi-trade site drive both the price and the timing on jobs like these.
Streets closer to Parramatta Park and the river foreshore sit near mature parkland that has been established for well over two centuries. Rebuilds on those blocks need the perimeter and under-slab system treated as seriously as any bush-edge property, since established green space like this supports termite activity that forages toward nearby gardens.
Away from the tower precinct, Parramatta's remaining houses, townhouses and semis sit on some of the oldest continuously developed residential land in the country. Ageing timber and sub-floors on these blocks need a fresh, documented termite management system on any rebuild or major extension.
What we install here
We work on Parramatta apartment and mixed-use tower developments near the stations and light rail, knockdown rebuilds on the older residential streets, and granny flats behind established homes closer to Parramatta Park. Basement and podium slabs are common on tower sites, while waffle pod and raft slabs remain standard on detached rebuilds. You get one fixed written quote covering every stage, and we attend in stages so a barrier visit never holds up a busy construction program.
Local knowledge
Our Parramatta work runs from the tower and mixed-use sites near the Church Street light rail stop and David Frater Reserve, where collar counts and multi-trade scheduling drive the job, out toward the older streets near Parramatta Park and the river, where established parkland shapes the perimeter detailing. Around CommBank Stadium, irrigated turf and large bin areas sit close to several apartment stages.
The City of Parramatta is the certifying council here, and it requires a durable meter-box notice along with a signed certificate from the installer, listing the products, the coverage and their licence, before an Occupation Certificate is granted. We have both ready as soon as our stage of a Parramatta build is finished, regardless of whether the project is a tower or a house.

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.

Parramatta questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215The same NCC requirement applies, but the job is scaled differently. A basement-level tower slab can carry a large number of service penetrations shared with commercial space, so collar counts and scheduling around a busy multi-trade construction program matter more than they would on a single detached home. We coordinate lift and loading dock access with the builder ahead of our visit.
Yes. Established parkland along the river foreshore supports termite activity that forages toward nearby gardens, so rebuilds on blocks close to the park get a full perimeter system rather than a partial strip, with attention to any junction where the slab meets the park boundary. We also check any drainage running through the park boundary as part of the same visit.
Yes, that is common work for us here. Collars go on after the plumber's rough-in and before the pour, so we plan our visit around the builder's program and attend in stages on a multi-dwelling site without holding up the concreter or the next trade following behind us. We keep a running schedule with the site supervisor to confirm timing each week.
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.
