St George & Bayside · AS 3660.1
With Lady Robinsons Beach on one side and Kogarah Bay on the other, Sans Souci in postcode 2219 has damp ground on two fronts, and a knockdown rebuild here needs its barrier detailed for both.
Quick answer
Yes, a new home or knockdown rebuild in Sans Souci needs a termite management system under the NCC, since it sits between two bays in a termite-prone part of Sydney. The system is installed to AS 3660.1 before the concrete pour, with collars fitted at every penetration. A durable notice for the meter box and an installation certificate for the certifier are both required before the Occupation Certificate.
Termite barriers in Sans Souci
Sans Souci sits about 14.8 km south-west of the CBD in postcode 2219, split across Bayside Council and Georges River Council. Water sits on two sides here: Lady Robinsons Beach and Cook Park on Botany Bay to the east, and Kogarah Bay to the west, with the Captain Cook Bridge crossing the Georges River north to Sans Souci. A shopping strip on Rocky Point Road near Sandringham Street carries most of the local retail, and boating clubs including the St George Sailing Club, St George Motor Boat Club and Botany Bay Yacht Club reflect how much of local life revolves around the water on both sides.
Homes near Kogarah Bay or Cook Park get close checks of sub-floor moisture and perimeter entry points from us, because the suburb's position between two bodies of water keeps soil damper than a typical inland block. That moisture is exactly the condition subterranean termites forage through, and Sans Souci's largely residential character means a barrier has to be planned around whichever bay a block sits closest to, since the two sides of the suburb do not carry identical ground conditions even though they're only a short walk apart, and outdoor structures near the water get the same close attention as the main house.

Local conditions
Three local factors shape how a Sans Souci barrier gets detailed.
Lady Robinsons Beach and Cook Park sit on the Botany Bay side of Sans Souci, and homes near that edge get close checks of sub-floor moisture, because damp ground like this is exactly what subterranean termites forage through looking for timber.
The suburb's western edge runs down to Kogarah Bay, and blocks on that side face the same kind of moisture pressure as the Botany Bay side, just from a different body of water. We check both edges of the suburb the same way.
Boat sheds, marinas and storage around the St George clubs mean outbuildings on many Sans Souci blocks sit right at the water's edge. Where an outbuilding needs its own termite protection, we plan that as part of the overall barrier.
What we install here
Sans Souci work is mostly knockdown rebuilds and renovations of homes near either bay, plus retirement village and boat shed sites along the water. Waffle pod and raft slabs suit most residential rebuilds, and we fit collars to every pipe and conduit penetration, running the perimeter to the true boundary. Homes near Kogarah Bay or Cook Park get particular attention to sub-floor moisture and perimeter entry points, and we schedule our visit around your builder's program throughout.
Local knowledge
Noel Seiffert Reserve sits close to much of our Sans Souci work, its grass and trees a reminder of the ground cover close to both bays. Beverley Park Golf Club, the nearest large irrigated area, adds moisture to blocks on that side of the suburb as well. Between Lady Robinsons Beach and Cook Park to the east and Kogarah Bay to the west, water shapes almost every barrier we detail here, and we treat the two sides of Sans Souci as genuinely different ground rather than one uniform suburb.
Sans Souci is split across Bayside Council and Georges River Council, and neither will issue an Occupation Certificate without a meter-box notice recording the system used and an installation certificate covering the products, the treated areas and the licensed installer's details. We get both documents ready as soon as our stage of a Sans Souci rebuild is finished, whichever of the two councils ends up certifying your address.

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.

Sans Souci questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. Homes near Kogarah Bay or Cook Park get close checks of sub-floor moisture and perimeter entry points from us, because the damp ground on that side of Sans Souci is exactly the condition subterranean termites forage through. We install a full, continuous perimeter on blocks close to either bay.
Sans Souci falls across both Bayside Council and Georges River Council, and both expect identical evidence before an Occupation Certificate: a meter-box notice and an installation certificate naming the products, the areas treated and the licensed installer. We get both ready regardless of which side of the suburb your address sits on.
Often, yes. Outbuildings, boat sheds and storage near the water sit in the same damp conditions as the main house, so where one needs its own termite management system we detail it as part of the overall barrier plan, with the same collars, perimeter and certification as the rest of the build.
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.
