Inner West · AS 3660.1
From the tower sites near the Bennelong Bridge to the newer blocks facing Sydney Olympic Park, we fit collars and perimeter systems into Wentworth Point slabs before the concrete goes down.
Quick answer
A termite management system is compulsory for any new home built in Wentworth Point, apartment or townhouse, before the certifier will issue the Occupation Certificate. Under the NCC, the whole City of Parramatta local area is classed as termite-prone, and the system has to meet AS 3660.1: every plumbing penetration collared, the perimeter closed off ahead of the pour.
Termite barriers in Wentworth Point
Wentworth Point sits on the western shore of Homebush Bay in the City of Parramatta, about 13 km west of the Sydney CBD in postcode 2127, on land reclaimed from the bay from 1949 onwards. Decades of plywood manufacturing, transport depots and Hyundai facilities have given way to almost wall-to-wall medium and high-density apartments, connected to Rhodes station across the water by the Bennelong Bridge and to Circular Quay and Parramatta by the Sydney Olympic Park ferry wharf. Our work here is almost entirely new apartment and townhouse slabs rather than standalone knockdown rebuilds, since so little of the suburb is left as separate housing.
A large apartment slab on reclaimed bay-side land brings its own termite considerations. Dozens of plumbing and service penetrations can run through a single pour, and any one of them left uncollared becomes a route in once the building is finished and occupied. The reclaimed ground itself, close to the water and to wetland remnants nearby, tends to hold moisture that keeps subterranean termites active locally, so the perimeter and every penetration need to be sealed properly before the concrete arrives, with almost no chance to fix a gap once the tower is built and tenanted.

Local conditions
Three things shape how we approach a termite barrier on a Wentworth Point build.
A typical Wentworth Point apartment or townhouse slab carries far more plumbing and service penetrations than a single house ever would, and each one needs its own collar. We price by penetration count and work closely with the plumber's rough-in schedule so nothing is missed before the pour.
Wentworth Point sits on land reclaimed from Homebush Bay, and that ground, along with nearby wetland remnants, tends to hold moisture well. Damp soil close to a slab edge is exactly what subterranean termites use to forage, so the perimeter treatment accounts for that dampness rather than assuming a typical Sydney block.
Once a tower or townhouse block is finished and tenanted, fixing a gap in the termite barrier means disruptive remedial work through someone's home. We treat every penetration and perimeter section as final on install day, because there is very little practical opportunity to correct it afterward.
What we install here
Nearly all of our Wentworth Point work is new apartment towers and townhouse blocks, since so little standalone housing land remains in the suburb. Podium and slab-on-ground construction both turn up depending on the site, and collars go on once the plumber has finished roughing in each stage. Pricing runs off the number of penetrations rather than a flat figure, and we stage visits tightly around the builder's construction program on what are often large, multi-stage sites.
Local knowledge
Much of our Wentworth Point work sits near Stromboli Park and the approach to the Bennelong Bridge, where new apartment entries back onto damp, planted garden beds. Newington Nature Reserve, a short walk away, adds wetland habitat that keeps moisture and mosquito pressure up around nearby towers. Toward Rhodes Waterside Shopping Centre across the bridge, food waste and busy foot traffic add rodent pressure that we factor into ground-floor and basement collar work.
The City of Parramatta certifies Wentworth Point builds, and its Occupation Certificate process requires proof a compliant termite system was installed before residents move in. We fix a durable notice inside the meter box or a nominated common area recording the system, and provide a separate installation certificate confirming the installer, the products used and the areas protected, prepared per building as the certifier requires.

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.

Wentworth Point questions

+61 450 515 215Once the plumber has roughed in a stage of the slab, collars go on before that section is poured, so we work directly off the builder's staged construction program rather than a single fixed date. On a large tower site, tell us the full staging plan early so collar counts and visit scheduling can be priced accurately from the start.
The reclaimed, low-lying ground around the bay holds moisture for longer than a typical Sydney block, so we don't treat it as a standard dry-climate site. The perimeter and soil treatment account for that persistent dampness, and we pay particular attention to any basement or ground-floor slab edge close to garden beds or wetland-facing boundaries.
Pricing is based on the number of penetrations through the slab rather than a flat per-dwelling rate, since a shared apartment or townhouse slab can carry a very large number of plumbing and service points. We provide one written quote covering the whole stage or building, and coordinate scheduling directly with the builder so the barrier work never becomes the item holding up a busy site.
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.
