South West Sydney · AS 3660.1
Under-slab membrane, collars and perimeter barriers installed to AS 3660.1 across Liverpool's apartment podiums and knockdown rebuilds, from the Georges River foreshore to the Elouera Bushland Reserve edge.
Quick answer
Yes, a new home, townhouse or apartment building in Liverpool needs a termite management system, since the City of Liverpool sits in a termite-prone area and the NCC requires a compliant system on any new dwelling there. It is installed to AS 3660.1, with collars and under-slab work completed before the concrete pour, and the durable notice and installation certificate provided to your certifier ahead of the Occupation Certificate.
Termite barriers in Liverpool
Liverpool was founded by Governor Lachlan Macquarie in 1810 on the western bank of the Georges River, making it one of the oldest European settlements in Australia, and today it is the administrative centre of the City of Liverpool, in postcode 2170 about 28 km west of the Sydney CBD. The city centre holds Westfield Liverpool, a busy railway station, hospitals and heritage buildings such as St Luke's Anglican Church and the Liverpool Courthouse, and housing ranges from heritage properties and 1960s Housing Commission estates to a growing number of apartment towers. Our work follows that mix, from knockdown rebuilds on older residential blocks to podium slabs in the city centre.
The Georges River runs along Liverpool's edge, and older homes near the river sit on soil that stays damper for longer, which suits subterranean termites looking for a way toward a new or replacement slab. Elouera Bushland Reserve adds another pocket of established vegetation close to residential streets, and 1960s-era homes being knocked down for rebuilds often carry decades of garden growth and buried timber from the original construction. In the city centre, apartment and commercial slabs bring a different demand entirely, dozens of penetrations on a single pour where getting every collar right matters more than the ground beneath.

Local conditions
Three conditions drive termite pressure across Liverpool, and they shift depending on which part of the city you are building in.
The Georges River keeps soil damp along parts of Liverpool's edge, and that moisture is what subterranean termites favour when foraging toward a new slab. Riverside and near-river blocks get a full perimeter rather than a minimal treated strip.
Elouera Bushland Reserve and the mature gardens on many older Liverpool blocks hold established termite activity in stumps, fallen timber and old fence lines. Rebuild sites near either one need the soil treatment and under-slab system checked as carefully as the perimeter.
Apartment and commercial slabs in Liverpool's city centre often carry many plumbing and service penetrations on a single pour, close to Westfield Liverpool and the hospital precinct. Every penetration needs a collar and a correctly lapped membrane, so we plan the count before the pour.
What we install here
We work across Liverpool on knockdown rebuilds of older Housing Commission-era homes, granny flats behind existing houses, and apartment or commercial podium slabs in the city centre, matching the system to whichever slab design your builder or engineer has specified. Multi-dwelling sites get a collar count and staging plan worked out ahead of the pour, and we provide one fixed quote from your plans covering every stage so a barrier visit never holds up your concreter.
Local knowledge
A good share of our Liverpool work sits near Elouera Bushland Reserve and along the Georges River, where older streets meet established vegetation and damp riverside ground. Dunbier Park and Whitlam Leisure Centre mark another cluster of residential rebuild work, where irrigated turf sits close to several boundaries. Around Liverpool station, Liverpool Plaza and Westfield Liverpool, our work shifts to apartment and commercial podium slabs with a higher collar count.
Liverpool is certified through the City of Liverpool, which requires the standard termite documentation on any new dwelling before it will issue the Occupation Certificate: a durable notice fixed in the meter box recording the system, 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 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.
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.

+61 450 515 215Yes. Any new building on termite-prone land needs a compliant system under the NCC, including apartment and commercial podiums in the city centre. We work from the plumbing and service drawings to plan the collar count before the pour, since these slabs usually carry far more penetrations than a house.
Established gardens on blocks like this often hide buried timber from the original construction, so we check the soil during the quote rather than assuming a clean start. Expect the same collars, under-slab work and perimeter as any new home, sized to what we actually find on site. We treat every quote as specific to your actual block.
It usually means more attention to the perimeter, since riverside soil holds moisture for longer and subterranean termites favour that dampness. We look at your block's actual distance from the river and any bushland reserve nearby before recommending a physical or chemical system. We are happy to talk through the specifics once we see your plans.
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.
