St George & Bayside · AS 3660.1
Perimeter protection detailed for Hurstville Grove's leafy, park-fringed streets, fitted before the pour on rebuilds running down toward Oatley Bay on the Georges River.
Quick answer
Yes, a new home in Hurstville Grove needs a termite management system, since Georges River Council sits within a termite-prone area under the NCC. Being tucked among reserves and close to the tidal Georges River foreshore, most blocks here warrant a full physical perimeter built to AS 3660.1. Occupation then depends on the meter box notice and a signed installation record reaching the certifier.
Termite barriers in Hurstville Grove
Hurstville Grove stretches from the small shopping cluster on Hillcrest Avenue down to the shore of Oatley Bay on the Georges River, on land first purchased in 1812 by merchant Simeon Lord, who called it Lord's Bush. The suburb still carries plenty of green space today, including Poulton Park, Willunga Reserve, Moore Park, Grove Park and Quarry Reserve, and most building work is knockdown rebuilds on the established, tree-covered blocks scattered among them. Each one needs its own properly certified termite management system before the certifier will approve occupation.
Unlike its busier neighbour Hurstville, the Grove is quiet and leafy, with homes set among mature trees and gardens rather than shops and towers, and that setting brings a different kind of pressure to bear on a new slab. Soil near a tidal inlet like Oatley Bay tends to stay damp for longer through the year, and moisture is one of the strongest drivers of termite activity there is. Combine that with the number of reserves threaded through the suburb, each holding leaf litter and fallen timber, and a Hurstville Grove rebuild generally warrants a more thorough barrier than a typical inland block would need.

Local conditions
Three things about Hurstville Grove's parks and waterfront setting push termite risk above the Sydney average.
Ground close to a tidal inlet like Oatley Bay tends to stay damper for longer through the year than higher, inland ground. Moisture is one of the strongest things that draws a foraging colony, so slab edges on lower blocks get particularly close attention.
Poulton Park, Willunga Reserve, Moore Park, Grove Park and Quarry Reserve all sit within or beside the suburb, each holding leaf litter and fallen timber where colonies can establish. Blocks near any of them typically need a fuller perimeter than a standard infill site.
Homes here sit among trees and gardens that have often grown for many decades. A knockdown rebuild clears the house but not the root systems and buried garden material, so soil treatment matters as much as the new slab edge.
What we install here
Nearly all our Hurstville Grove work is knockdown rebuilds on established, tree-covered blocks, generally on waffle pod or raft slabs, with suspended sections where a block falls toward the bay. We fit a collar to every penetration once the plumbing rough-in is finished and typically recommend a full physical perimeter given the reserves and waterfront nearby. One fixed quote from the plans covers the whole job through to your final certificate.
Local knowledge
Our Hurstville Grove work sits among the green pockets of Poulton Park, Willunga Reserve and Quarry Reserve, running down toward Oatley Bay and the Georges River foreshore. Blocks closest to the water or bordering one of the suburb's several reserves get the fullest perimeter detailing, while sites nearer Hillcrest Avenue's small shopping cluster are more standard rebuild jobs.
Georges River Council certifies building work in Hurstville Grove. Before it will issue an Occupation Certificate, its certifiers need a durable notice fixed inside the meter box and a written record naming the products used, the areas covered and the installer. We prepare both once the barrier is complete, together with advice on maintaining protection near the waterfront and surrounding reserves.

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.

Hurstville Grove questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes, generally. Soil near a tidal inlet like Oatley Bay tends to hold moisture for longer than higher ground further from the water, and that dampness is one of the main things a foraging colony is drawn to. We pay closer attention to slab-edge detailing on properties within reach of the bay.
Often, yes. With Poulton Park, Willunga Reserve, Moore Park, Grove Park and Quarry Reserve all threaded through the suburb, a good number of blocks border bushland or garden reserve on at least one side. Those sites typically get a fuller physical perimeter than a block sitting well away from any green space.
As soon as your builder can confirm a rough pour date, since installation needs to happen once the plumbing rough-in is complete and before the concrete arrives. On blocks running down toward the bay, flag the slope and any retaining walls early so we can plan the perimeter properly.
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.
