Inner West · AS 3660.1
Under-slab membrane and perimeter barriers installed to AS 3660.1 for Marrickville rebuilds, unit stages and industrial slabs, from the Cooks River floodplain to the South Marrickville warehouse strip.
Quick answer
Yes, a new home, rebuild or apartment building in Marrickville needs a termite management system, since the suburb sits in a termite-prone part of the Inner West Council area and the NCC applies across every property type here. 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 your certifier before the Occupation Certificate.
Termite barriers in Marrickville
Marrickville is a large Inner West Council suburb in postcode 2204, about 7 km south-west of the Sydney CBD, with housing ranging from Federation bungalows and terrace houses to modern units, and flats and apartments now making up almost half of all homes. The Cooks River forms the southern boundary, Marrickville Road and Illawarra Road are the main shopping strips, Marrickville Metro sits on the site of a former woollen mill, and south Marrickville still holds substantial industrial land used for car repairs, factories and warehouses. Our work here ranges from a terrace rebuild to a unit podium or a commercial slab.
Few suburbs combine this many property types, and each brings its own termite conditions. Federation houses and terraces can have old timber sub-floors and shared party walls that carry undetected activity for years, and rebuild blocks in these streets often uncover buried timber from earlier construction. Homes near the Cooks River deal with more soil moisture, which subterranean termites favour when foraging toward a slab, and the industrial land toward the south brings large commercial slabs with many penetrations. We match the barrier to whichever of these conditions actually applies to your site.

Local conditions
Three conditions shape termite risk across Marrickville, and they depend on which part of the suburb you are in.
Marrickville's Federation terraces often sit on narrow blocks with shared party walls and timber sub-floors that can carry termite activity for years without being noticed. A rebuild next to one of these homes starts with that context, not a clean slate.
The Cooks River forms Marrickville's southern boundary, and the surrounding parkland keeps soil moist enough to suit subterranean termites as well as mosquitoes. Blocks near the river get a full perimeter rather than a minimal treated strip.
South Marrickville's factories, warehouses and car repair sites bring large commercial slabs with many plumbing and service penetrations. Every one needs a collar and a correctly lapped membrane, so we plan the layout from the engineering drawings before the pour.
What we install here
We work across Marrickville on terrace and Federation house rebuilds, unit and apartment podium stages near the shopping strips, and commercial and industrial slabs in the south. We install under-slab membrane, collars and a physical or chemical perimeter matched to the slab design, whether that is a small residential pour or a large warehouse floor. One fixed quote from your plans covers every stage of the build. Nothing here is guesswork, it is measured straight off the plans.
Local knowledge
Our Marrickville work sits close to Petersham Road Reserve and along the Cooks River near Annette Kellerman Aquatic Centre, where riverside ground keeps termite pressure higher than further inland. Around Marrickville station, Marrickville Road and Illawarra Road, the work is more often a terrace rebuild or unit stage on a tight block. South of the rail line, industrial sites toward Sawyer Reserve bring larger commercial slabs into the mix.
Marrickville is certified through the Inner West Council, which requires the standard termite documentation on any new dwelling or commercial building before it will issue the Occupation Certificate: a durable notice fixed in the meter box, and an installation certificate naming the products used, the areas protected and the installer's licence. We supply both, along with product data, as soon as the work is done.

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.

Marrickville questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Often, yes. Shared party walls and old sub-floor timber can already carry termite activity that has gone unnoticed for years, so we inspect the neighbouring structure as part of the quote. The barrier itself still follows the same collars, membrane and perimeter standard as any rebuild. Just get in touch and we will talk through the details.
Yes. Riverside soil holds moisture longer than blocks further from the water, and that favours subterranean termites, so we generally recommend a full physical perimeter rather than a minimal strip for anything near the Cooks River corridor. We treat every quote as specific to your actual block. We are happy to talk through the specifics once we see your plans.
Yes, we regularly work on commercial and industrial slabs in that part of the suburb. We take the collar count from the engineering and plumbing drawings before the pour, fit every penetration in one visit, and provide a single installation certificate for the whole slab. Reach out early so we can lock in a suitable date.
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.
