Sutherland Shire · AS 3660.1
Perimeter and under-slab termite barriers installed to AS 3660.1 for Loftus new homes and rebuilds backing onto Royal National Park, from Loftus Reserve to the TAFE and university precinct.
Quick answer
Yes, a new home or rebuild in Loftus needs a termite management system, since the suburb sits in a termite-prone part of the Sutherland Shire and borders Royal National Park directly. The system is installed to AS 3660.1, with collars and under-slab work completed before the concrete pour, and the durable notice plus installation certificate provided to your certifier before the Occupation Certificate.
Termite barriers in Loftus
Loftus is a residential suburb in postcode 2232, about 25 km south-west of the Sydney CBD, within the Sutherland Shire, with a bushland atmosphere that borders Royal National Park along its south-eastern edge. Loftus station on the Illawarra line sits beside TAFE and University of Wollongong campuses, and the Sydney Tramway Museum runs heritage trams toward Royal National Park station. Most homes here are detached houses on established gardens, and the building work we see is mostly a knockdown rebuild or a granny flat rather than a new estate. It is part of how we plan each visit.
Sitting hard against Royal National Park means bushland is never far from a Loftus block, and that proximity is the single biggest factor in how we detail a barrier here. Subterranean termites forage from the park through leaf litter, fallen timber and old stumps toward the nearest slab edge, and established gardens on rebuild sites often add decades of buried timber from a previous house on top of that bush pressure. Loftus Reserve and several smaller reserves scattered through the suburb bring the same conditions closer to homes that are not directly on the park boundary.

Local conditions
Three things push termite pressure higher in Loftus than in suburbs further from the national park.
Loftus borders Royal National Park along its south-eastern edge, and that much bushland holds established termite colonies with an easy path to nearby blocks. Homes backing directly onto the park almost always need a full physical perimeter.
Loftus Reserve and several smaller reserves scattered through the suburb bring the same leaf litter, fallen timber and damp ground as the national park, just closer to homes not directly on the boundary. We check every nearby reserve during the quote.
Knockdown rebuild sites in Loftus typically sit on decades-old gardens with buried timber and mature planting from the previous house. That material can feed a colony long before the new slab goes down, so soil treatment matters as much as the perimeter.
What we install here
We install perimeter and under-slab termite systems for Loftus new homes, knockdown rebuilds and granny flats, with particular attention to blocks near Royal National Park, Loftus Reserve or the smaller bushland pockets through the suburb. Waffle pod and raft slabs are typical, with suspended sections on blocks that fall toward a gully. One fixed quote from your plans covers every stage, and we attend after your plumber's rough-in so the barrier does not hold up the pour.
Local knowledge
Most of our Loftus work sits close to Royal National Park along the suburb's south-eastern edge, and near Loftus Reserve and the smaller reserves through the middle of the suburb, where bushland brings termites closer to established homes. Around Loftus station, the Sydney Tramway Museum and the TAFE and university campuses, rebuild and infill work sit a little further from the park boundary but still within easy reach of bush pests.
Loftus is certified through the Sutherland Shire, which requires the standard termite documentation before it will issue an Occupation Certificate: an installation certificate sets out which products were used, the installer's licence number and which areas were treated, while a durable notice goes up inside the meter box. We provide both, along with maintenance advice suited to a bushland-adjacent property, as soon as the work is complete.

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

Loftus questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Usually, yes. Bushland pressure from the park is higher than in an average Sutherland Shire street, so we generally recommend a full physical perimeter rather than a minimal strip, with careful detailing at any point where the slab edge sits close to the bush boundary. It also keeps your certifier's paperwork straightforward and complete.
It does. Mature gardens often hide buried timber from the previous house that can already be feeding termite activity before the rebuild starts. We treat the soil and check for that material during the quote so the barrier is sized correctly. Feel free to ask us anything else not covered here.
After the plumber has set out the new drainage and before the concrete pour, the same timing as any new home. On a bushland-adjacent block we like to see the retaining and landscaping plans early, since step-downs near the boundary need extra detailing. We are glad to answer further questions once we are on 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.
