St George & Bayside · AS 3660.1
Perimeter barriers and under-slab systems fitted to Peakhurst Heights blocks before the pour, on ground running down to Boggywell Creek, Lime Kiln Bay and the edge of Gannons Park.
Quick answer
Yes. Peakhurst Heights sits between a tidal bay and bushland reserves, so a new home or rebuild needs an NCC termite management system installed to AS 3660.1. Collars and 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 needed before the Occupation Certificate is issued.
Termite barriers in Peakhurst Heights
Peakhurst Heights is a mainly residential suburb in postcode 2210, about 19.2 km south-west of the CBD, in the Georges River Council area. It is bordered by Boggywell Creek and Lime Kiln Bay on the Georges River, and some residents still think of it as part of neighbouring Peakhurst. Gannons Park is a large recreation area in the north-west corner, Hurstville Golf Course sits on the eastern border, and a small group of shops is located on Pindari Road. Our work here is mostly rebuilds and renovations on established blocks rather than new subdivision.
The shores of Lime Kiln Bay once held Aboriginal shell middens, a reminder of how long people have used this stretch of the Georges River, and today the same creek, bay, golf course and reserves shape what a termite barrier needs to deal with. Damp soil near Boggywell Creek and the bay gives subterranean termites easy movement toward a slab, and the bushland fringes of Gannons Park hold established colonies that forage into nearby gardens. With limited commercial activity in the suburb, almost all of our work here is protecting homes from these surrounding natural conditions.

Local conditions
Three things shape termite risk in Peakhurst Heights, tied to the creek, the bay and the parkland around it.
With Boggywell Creek and Lime Kiln Bay forming much of the suburb's border, ground near the water holds moisture for longer than blocks further inland. That dampness makes it easier for termites to move toward a slab, so we give drainage and the slab edge extra attention on properties near either waterway.
Gannons Park in the north-west corner holds established bushland that supports termite activity foraging into nearby gardens. Rebuilds on blocks backing onto the park get a full perimeter system, with particular care at any junction where the slab meets the park boundary.
Hurstville Golf Course runs along the suburb's eastern edge, and irrigated fairways keep nearby ground damper than blocks further from the course. Properties that share a fence line with the golf course get closer attention to drainage and slab edge detailing for the same reason.
What we install here
We work on Peakhurst Heights knockdown rebuilds and renovations on established blocks near the creek, the bay and the two green boundaries formed by Gannons Park and Hurstville Golf Course. Suspended floors and piers turn up on blocks that fall toward the water, alongside waffle pod slabs on more level pads nearer Pindari Road. You get one fixed written quote from the plans covering every stage, and we attend around your plumber's rough-in and the concreter's pour date.
Local knowledge
Most of our Peakhurst Heights work sits near H. V. Evatt Park and the Boggywell Creek and Lime Kiln Bay foreshore, where damp ground shapes the slab edge detailing, and along the Hurstville Golf Course boundary, where irrigated fairways keep neighbouring blocks damper for longer. Toward Beauty Point Reserve, bushland links into the wider green corridor around Gannons Park. We check the bay and creek foreshore closely on any property within a short walk of the water.
Before it will grant an Occupation Certificate for a Peakhurst Heights property, Georges River Council needs a meter-box notice recording the termite system, plus a signed certificate from the installer naming the products, the coverage and their licence. We finalise both as soon as our stage of the work is complete, so a Peakhurst Heights rebuild is not left waiting on us.

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 drainage and the slab edge are detailed. Ground near Boggywell Creek and Lime Kiln Bay holds moisture longer than blocks further inland, and that dampness makes it easier for subterranean termites to move toward a slab, so we check drainage falls closely on properties near the water.
Yes. Established bushland in the park supports termite activity that forages into nearby gardens, so we run a full perimeter system on blocks near that edge rather than a partial strip, and pay close attention to any junction where the slab meets the park boundary. We also check the golf course boundary for irrigation runoff as part of the same visit.
As soon as you have a rough slab date from the builder. Collars and any under-slab system need to go in after the plumber's rough-in and before the pour, so we lock our visit into that window. On blocks near the creek or bay, tell us early if there is a known drainage issue on the property.
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.
