Sutherland Shire · AS 3660.1
Collars, membrane and a full perimeter system staged around the builder's pour date for Alfords Point 2234 rebuilds on the sloping blocks running down toward Georges River National Park.
Quick answer
Yes: a new home or rebuild in Alfords Point needs a termite management system, because the suburb backs onto Georges River National Park within a termite-prone stretch of Sutherland Shire. The system goes in to AS 3660.1 before the slab is poured, collars first, perimeter detailed around any retaining work. A durable notice and installation certificate then go to the certifier ahead of the Occupation Certificate.
Termite barriers in Alfords Point
Alfords Point sits on the southern bank of the Georges River in postcode 2234, about 21.6 km south-west of the CBD and within Sutherland Shire. Modern Alfords Point grew in the late 1970s and 1980s, when large bushland plots were subdivided alongside the Menai town centre, so most of the housing is detached family homes on sloping, tree-covered blocks. Rebuild activity on that original 1970s and 1980s stock is common, and every rebuild, garage slab or granny flat here carries the same termite management obligation under the NCC as a fresh block would.
The defining feature of Alfords Point is how much bush surrounds the houses. Georges River National Park wraps around much of the suburb, with walking tracks and fire trails running close to back fences, and the sloping blocks common here often need cut-and-fill or retaining to get a level pad. Both conditions matter for a barrier: bushland edges hold established termite colonies that forage into the nearest yard, and every retaining wall or step-down in a sloping slab is a junction where a barrier has to be detailed properly rather than improvised on site.

Local conditions
Three conditions on an Alfords Point block change how the barrier is planned and installed.
The park wraps much of the suburb, and colonies living in its fallen timber and leaf litter forage well beyond the fence line. On blocks backing directly onto the reserve we run the perimeter continuously along that bushland edge, rather than treating it as a token strip.
The tree-covered, sloping terrain typical of Alfords Point often needs retaining and fill to create a level building pad. Every step-down and retaining wall junction is a spot where a poorly detailed barrier leaves a gap, so we plan those details from the engineering drawings before we start.
Much of the suburb's original housing dates from when the bushland plots were first subdivided, and rebuild sites on that older stock often carry decades of garden growth and old timber. That material needs to be accounted for in the soil treatment, not just the new slab edge.
What we install here
We work on Alfords Point new homes, knockdown rebuilds and granny flats on the sloping blocks near Georges River National Park. Suspended floors and piers are common where a block falls away toward the reserve, alongside waffle pod and raft slabs on the flatter pads. Retaining walls and cut-and-fill are detailed from the engineering plans before we quote, and our visit is timed to your builder's program so the pour is never delayed by the barrier work.
Local knowledge
Most Alfords Point jobs sit close to Georges River National Park, where bushland runs right up to back fences on the streets nearest the reserve boundary. Blocks near Casuarina Oval tend to be more straightforward, flatter sites with a standard slab-edge and penetration job. The closer a block sits to the park, the more attention the perimeter and any retaining wall junction get, since that is where colony pressure from the bush is highest.
Sutherland Shire certifies work in Alfords Point, and getting to sign-off means two things land on file: signage secured permanently inside the meter box, and paperwork naming the products used, our licence and what was covered. We hand both over on the day, plus product information and maintenance advice, and note any retaining wall or step-down detailing carried out as part of the job.

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.

Alfords Point questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215They need closer attention to the perimeter than a block further from the reserve, because established bushland colonies forage well beyond the park boundary. On Alfords Point blocks backing the park we typically recommend a full physical perimeter system, with the reticulation line kept clear of any future paving or landscaping over the treated zone.
We work from your engineering drawings to detail the barrier at every step-down, retaining wall and fill batter before installation starts, because those junctions are where a rushed barrier leaves gaps. Suspended sections and piers on the lower part of a sloping block are treated differently to a standard slab-on-ground section.
Yes. A secondary dwelling needs its own compliant system under the NCC, with collars on every penetration and a perimeter or under-slab system matched to how the granny flat is built. If the existing house is already protected, we look for a way to connect the two systems, but the new structure is priced and covered on its own terms.
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.
