Inner West · AS 3660.1
Barrier work for Enfield 2136 rebuilds and extensions near Henley Park, Coronation Reserve and the busy Liverpool Road corridor, on land settled since the mid-1800s.
Quick answer
Yes. Enfield sits in a termite-prone part of Sydney, which means the National Construction Code requires a termite management system for a new home or a major rebuild here. Fitting has to be finished to AS 3660.1 before the concrete goes down. What follows is paperwork: a durable notice sealed into the meter box, and an installation certificate, both handed to your certifier ahead of the Occupation Certificate.
Termite barriers in Enfield
Enfield is a residential suburb in the Municipality of Burwood, about 11.1 km west of the CBD in postcode 2136, that grew from a mid-1800s staging post on Liverpool Road, with St Thomas' Anglican Church from the 1840s still standing as its oldest building. Housing is mostly established detached homes from across the twentieth century, and new work in the suburb is almost always a knockdown rebuild, a second-storey addition or a granny flat on an existing block rather than any new estate, close to Henley Park and the historic Enfield Olympic Pool.
Older detached housing on established blocks means a rebuild is usually going up where a house, sheds and mature gardens have stood for decades, and that soil history matters as much as the suburb's setting. Parks such as Henley Park and Coronation Reserve add nearby garden beds and mature trees, while the Enfield Intermodal Logistics Centre close by brings ongoing earthworks. All of it can disturb ground and push termite activity towards a freshly poured slab if the barrier is not detailed with the site's history in mind, so we assess each block on its own record.

Local conditions
Three things about Enfield shape how a barrier gets fitted there.
Enfield rebuilds usually go up where a house and garden have stood for decades, and old stumps or buried timber in that soil can feed termite activity long before a new slab is poured. We look at what the site is carrying before recommending the barrier scope.
Henley Park and Coronation Reserve sit close to many Enfield streets, and mature trees and garden beds in parkland like that give termite colonies cover near residential blocks, especially where a fence line backs directly onto the reserve.
Ongoing works around the Enfield Intermodal Logistics Centre in neighbouring Strathfield South can disturb soil and displace termite activity onto surrounding residential streets, adding pressure that a standard barrier plan needs to account for rather than assume away.
What we install here
Our Enfield work is mostly knockdown rebuilds, second-storey additions and granny flats on established blocks rather than any new estate, reflecting a suburb built out generations ago. We fit collars, membrane and perimeter treatment to suit standard and waffle pod slabs, timing the visit to when the plumber finishes rough-in and the builder sets a pour date, and we check what the existing garden and any old sheds on site might already be feeding before the new barrier goes in.
Local knowledge
Cooinoo Reserve sits close to many Enfield streets, with Burwood Plaza and the Frog Conservation Area a short distance further out. Rebuild sites near either reserve get closer attention to perimeter coverage given the nearby garden beds and mature trees, while blocks closer to Liverpool Road tend to be tighter, established infill with less garden space to assess but more foot traffic and services to work around.
The Municipality of Burwood certifies new builds and rebuilds throughout Enfield. Its certifiers require a durable notice for the meter box alongside an installation certificate naming the products and the areas protected, before they will issue the Occupation Certificate. We get both documents ready the moment the barrier work is complete, along with product data sheets, so your paperwork is never the delay.

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.
Paperwork
A complete document set for the builder, the certifier and every future owner of the property.
A permanent notice in the meter box showing the system, install date, installer, any chemical's life expectancy and inspection advice.
For: certifier, owner, future owners
Written confirmation of the system and products used, the areas protected and our licence details.
For: builder, certifier, owner
Details of the physical system or termiticide installed, including safety data sheets for any chemicals.
For: builder, owner

+61 450 515 215It can. Old stumps, roots and buried timber from decades of garden growth can support termite activity before a new slab is even poured, so we assess the site and may recommend soil treatment alongside the standard collars and perimeter system, particularly on blocks where large trees have been removed recently.
Reserves such as Henley Park and Coronation Reserve give termite colonies mature trees and garden beds to shelter in close to the street, so blocks near either get the full perimeter treated as standard rather than a partial strip, with extra attention to the side of the block facing the parkland.
Yes, where the addition involves a new slab or footing we fit collars and perimeter or under-slab treatment to that section, and we check how it ties into any existing protection on the original house so the whole building is covered rather than just the new part built during the current stage of work.
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.
