St George & Bayside · AS 3660.1
Perimeter barriers and under-slab systems installed before the pour across Peakhurst, from homes near the Salt Pan Creek corridor to industrial slabs around Boundary Road.
Quick answer
Yes. A new home, rebuild or industrial building in Peakhurst needs an NCC termite management system installed to AS 3660.1. Collars and any under-slab work go in before the concrete pour. The durable notice for the meter box and an installation certificate for the Georges River Council certifier are both required before the Occupation Certificate is issued.
Termite barriers in Peakhurst
Peakhurst sits in postcode 2210, about 18.2 km south-west of the CBD, in the Georges River Council area. Its western border follows Salt Pan Creek, which flows into the Georges River, and commercial activity is concentrated along Forest Road and Boundary Road, including shops, cafes and restaurants near the Peakhurst Inn Hotel and a sizeable industrial area around Boundary Road. The nearest station is in Riverwood, and Forest Road links through to Henry Lawson Drive. Our work spans residential rebuilds, industrial slabs and the occasional development near Peakhurst Park and the sporting fields at Gannons Park.
Peakhurst's mix of settings gives it a wider range of ground conditions than a purely residential suburb. Homes closer to Salt Pan Creek sit on ground that holds moisture for longer, and that dampness makes it easier for subterranean termites to move toward a slab. The industrial precinct around Boundary Road brings sites with a history of heavy use, where filled or disturbed ground needs the under-slab membrane and collars checked as carefully as anywhere else. Peakhurst Park and Gannons Park add established green space close to several residential streets, which shapes how far the perimeter needs to extend on nearby rebuilds.

Local conditions
Three things shape termite risk across Peakhurst, tied to the creek corridor, the industrial precinct and the parks.
Peakhurst's western border follows Salt Pan Creek on its way to the Georges River, and ground near a creek line holds moisture for longer than the rest of the suburb. Homes close to that corridor get extra attention on drainage and the slab edge, since damp soil is what makes it easier for termites to move toward a slab.
The sizeable industrial area around Boundary Road brings sites with decades of heavy use behind them, where the ground can be filled or disturbed. We treat the under-slab membrane and every collar as the first line of defence on sites like this, since uneven fill can hide a path for termites.
These two large recreation areas sit close to a number of residential streets, and established trees and garden beds near a park boundary can shelter termite activity that forages toward nearby homes. Rebuilds near either park get the same perimeter attention as a bush-edge property.
What we install here
We work on Peakhurst knockdown rebuilds and renovations near Salt Pan Creek and the two parks, plus industrial and light commercial slabs around the Boundary Road precinct. Waffle pod and raft slabs are standard on residential rebuilds, while industrial sites are priced from the plans with collar counts confirmed before we arrive. You get one fixed written quote covering every stage, and we attend around your builder's program so the barrier never holds up the pour.
Local knowledge
Our Peakhurst work runs from the homes near Caledonia Crescent Reserve and Salt Pan Creek, where drainage and slab edge detailing matter most, out toward the Boundary Road industrial precinct, where fill and disturbed ground need careful checking. Around Hurstville Golf Course and Mortdale Plaza, irrigated turf and shopping centre proximity shape what we check first on nearby rebuilds. We check fill conditions closely on any site near the former industrial land before quoting.
Georges River Council is the certifying authority for Peakhurst, and before it will issue an Occupation Certificate it wants a durable notice inside the meter box and a certificate from the installer covering the products, the coverage and the licence held. Both documents are ready once our stage of a Peakhurst rebuild or industrial fit-out 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.
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 changes how carefully we detail drainage and the slab edge. Ground near the creek corridor stays damper than the rest of the suburb, and that moisture makes it easier for subterranean termites to move toward a new slab, so we check drainage falls closely on properties near the water.
Yes, any building with habitable or occupied space still needs a compliant termite management system under the NCC. Industrial sites in this precinct can also have filled or disturbed ground from decades of prior use, so we check the fill and detail the membrane and collars carefully rather than assuming it is clean.
They get more attention to the perimeter rather than a different product. Established trees and garden beds near either park can shelter termite activity that forages toward nearby homes, so we run a fuller perimeter system on blocks backing onto that green space. We also check what protection any neighbouring property already has before finalising the plan.
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.
