Blacktown & Mount Druitt · AS 3660.1
Under-slab membrane and perimeter barriers installed to AS 3660.1 for Mount Druitt rebuilds and unit stages, around the Westfield Mt Druitt commercial centre. That local knowledge shapes every quote we put together.
Quick answer
Yes, a new home, rebuild or unit building in Mount Druitt needs a termite management system, since the suburb sits in a termite-prone part of the City of Blacktown and the NCC applies to the commercial centre as much as the surrounding streets. 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.
Termite barriers in Mount Druitt
Mount Druitt is a major commercial and transport centre in the western part of the City of Blacktown, in postcode 2770 and about 38 km west of the Sydney CBD, taking its name from the land grant Governor Macquarie made to Major George Druitt. Its railway station is on the T1 Western Line and saw its first electric train in 1955, Westfield Mt Druitt and a courthouse sit close to the station, and The Manse, an 1880s Georgian cottage on The Avenue, is now home to the local historical society. Our work here ranges from unit blocks near the centre to knockdown rebuilds in the surrounding residential streets.
A regional centre like this brings concentrated commercial activity, shared buildings and busy transport corridors, and each affects termite risk in a different way. Unit blocks near the station and shopping centre pour a single large slab with many plumbing and service penetrations, where getting every collar right matters more than the ground beneath. In the residential streets further out, older houses can carry decades of buried timber and fence lines from previous construction, and timber garden structures give termites a food source close to the boundary if left unchecked. We treat each property type differently rather than applying one standard approach.

Local conditions
Three conditions shape termite risk across Mount Druitt, depending on whether you are near the centre or the residential streets.
Apartment and unit sites near the station and shopping centre typically pour one large slab with dozens of plumbing and service penetrations. Every one needs its own collar and correctly lapped membrane, planned from the drawings before the pour.
Houses in Mount Druitt's residential streets often sit on decades-old gardens, and a rebuild there can uncover buried timber and old fence lines from a previous house. We check the soil as carefully as the slab edge.
Timber fences and garden structures on established Mount Druitt blocks can carry termite activity for years without being noticed. We treat these structures as part of the property when planning a rebuild's perimeter, not as separate from it.
What we install here
We work on Mount Druitt unit and apartment podium slabs near the centre and knockdown rebuilds on the surrounding residential streets. We install under-slab membrane, collars and a physical or chemical perimeter matched to the slab design, with collar counts worked out from the plumbing plans on multi-dwelling sites. One fixed quote from your plans covers every stage of the build. That keeps the whole build on schedule from footings to handover.
Local knowledge
Our Mount Druitt work sits close to Westfield Mt Druitt and Mount Druitt station, where commercial food waste and rail corridors both come up in our site assessments, and near Fred Cowpe Reserve, where grass and trees shelter pests close to several homes. Around the residential streets away from the centre, our work shifts toward standard knockdown rebuilds and fence-line checks.
Mount Druitt is certified through the City of Blacktown, which requires the standard termite documentation before it will issue the Occupation Certificate: an installation certificate details the products applied, the installer's licence and the zones covered, while a durable notice sits inside the meter box. We supply both, along with product data, as soon as the barrier work 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.

Mount Druitt questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. Any new residential building on termite-prone land needs a compliant system under the NCC, unit podiums included. We work from the plumbing and service drawings to plan the collar count before the pour, since these slabs carry far more penetrations than a house. Feel free to ask us anything else not covered here.
Yes. Old fences and garden structures can carry undetected termite activity for years, so we check that material during the quote rather than assuming a clean start. The barrier itself still follows the standard collars, membrane and perimeter to AS 3660.1. We are glad to answer further questions once we are on site.
As soon as you have a rough slab date, since collars and any under-slab system go in after the plumber's rough-in and before the pour. Let us know your site access early so we can plan the visit around your builder's schedule. This keeps everything properly documented for future reference too.
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.
