Low ground near the Nepean
River-flat soils hold moisture, and damp soil next to a warm slab is prime foraging ground. Perimeter and edge detailing carries more weight here than on drier blocks further up the hill.
Quick answer
Yes. Building a new house at Jamisontown means installing a termite management system under the NCC, built to AS 3660.1. Penetration collars and the under-slab component are fitted after the plumber's set-out and before concrete arrives. The paperwork, an installation certificate and a durable notice, goes to your certifier for the Occupation Certificate.
Termite barriers in Jamisontown
Why Jamisontown builds need the barrier in before the pour
Jamisontown lies on the eastern bank of the Nepean just south of Penrith, in the City of Penrith's south ward, about 51 km west of the city. Named after Thomas Jamison, who took a grant here in 1805, it stayed rural for roughly 150 years before subdivision began in the 1960s and the suburb was gazetted in 1976. That history shows in the streets: brick homes from the sixties onward, now reaching the age where owners knock down and rebuild, plus infill and secondary dwellings squeezed onto generous older lots.
Ground conditions matter here more than in most western suburbs. Residential streets sit low, close to the river, where soil stays moist longer after rain and riverbank vegetation keeps organic material in the ground. Moisture and buried timber are exactly what subterranean colonies need, and a fresh slab gives them a target. Everything they use to get inside unseen, pipe penetrations, an unprotected edge, a construction joint, is sealed off only while the site is still open, which is why the barrier is planned around the pour rather than after it.

Local conditions
What makes Jamisontown blocks a termite risk
Jamisontown blocks carry three specific pressures worth designing for.
Sixties-era rebuild sites
Knockdowns on original 1960s lots come with decades of garden beds, buried offcuts and old stumps. That timber can already be feeding a colony when your pad is prepared, so soil treatment and under-slab protection both matter.
Mulgoa Road corridor sites
Commercial and mixed-use slabs along the Mulgoa Road spine carry high penetration counts. Collar numbers and staging, not floor area alone, drive what these jobs take.
What we install here
Building in Jamisontown
Work in Jamisontown runs from single replacement homes and granny flats through to duplex pairs and the occasional commercial pad off Mulgoa Road. Waffle pod and raft slabs dominate, and we fit collars to every service, lay an under-slab membrane or apply a treated zone as specified, then complete the perimeter as brickwork rises. Where paving or landscaping will sit over the treated soil, a reticulation line keeps future top-ups possible. Quotes are fixed from the plans, with each stage listed so nothing surprises the builder.
- Under-slab membraneA termite-resistant sheet laid across the prepared ground before the pour.
- Penetration collarsCollars sealed to every pipe and conduit that comes up through the slab.
- Perimeter & slab edgeA barrier at the slab edge and into the cavity, so nothing can track up hidden.
- Chemical soil barrierAn APVMA-registered treated zone in the soil under and around the building.
- ReticulationA pipe network laid before paving so the treated zone can be topped up later.
- Piers & suspended floorsProtection for bearers, piers and suspended timber floors on sloping blocks.
Local knowledge
Around Jamisontown
Most jobs here sit within a short drive of the Penrith Homemaker Centre precinct just off Mulgoa Road, with residential work spread through the streets near Gibbes Street Reserve and out towards Huntington Reserve a little over a kilometre away. The Penrith Ice Palace marks the commercial side of the suburb, where slabs are bigger and penetration counts climb. Blocks closest to the river corridor get the most careful perimeter detailing.
Builds at Jamisontown are certified under the City of Penrith. Before your Occupation Certificate can be issued, the certifier needs evidence that a compliant system is in place: a certificate naming the products installed, the areas they protect and the installing technician, together with a durable notice mounted in the meter box recording the same details and the recommended inspection interval. We supply both, plus product information for the owner's records.

Systems we install
The right barrier for your slab and your site
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.
01Under-slab membrane
A termite-resistant sheet laid over the whole prepared footprint before concreting, so termites can't come up through the slab anywhere.
02Penetration collars
A sealed collar on every pipe, conduit and service that passes through the slab. These gaps are the most common hidden way in.
03Slab edge & cavity barrier
Protection at the slab edge and into the wall cavity, which stops termites building hidden tunnels up the outside of the slab.
04Chemical soil barrier & reticulation
An APVMA-registered termiticide zone in the soil, with an optional pipe network under paving so it can be recharged later without digging.
05Suspended floors & piers
Barriers for bearers, piers and raised timber floors on sloping or elevated blocks, where there's no slab to protect.
06Retaining walls & tricky sites
Detailing for sandstone cuts, block retaining walls, step-downs and cut-and-fill sites, which are common across Sydney.
Why during construction
Do it now, or pay more to do less later
A retrofit can only treat around a finished house. A pre-construction system protects the parts nobody will ever be able to reach again.
Costs far less
A barrier put in during the build costs a fraction of a post-construction system, and far less than repairing termite damage.
Meets the NCC
New houses (Class 1) and outbuildings (Class 10) with termite-susceptible framing need a compliant termite management system.
Hidden gaps sealed
Pipe penetrations and slab joints can only be fully protected while they're still open, before the concrete goes in.
The whole footprint
An under-slab system covers ground that no treatment from outside the finished house can ever reach.
No OC delays
Your certifier needs the certificate and durable notice before issuing the Occupation Certificate. We supply both together.
Easier to sell
Documented, compliant protection gives buyers, building inspectors and lenders confidence when the home is sold.
Installation stages
Installed in stages that follow your build
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.
Step 01Design / DA
Plans & fixed quote
Send your plans and slab details. We recommend a system and give you one fixed price that covers every stage.
Step 02Before the pour
Collars & under-slab
Collars go on every service once the plumber has set out, then the membrane or soil treatment is installed across the prepared site.
Step 03Walls going up
Slab edge & cavity
Perimeter and cavity protection is fitted as the brickwork or cladding goes up, so there's no unprotected gap at the slab edge.
Step 04Before landscaping
Final perimeter
Where it's specified, the chemical perimeter or reticulation system is completed around the building before paths and gardens go in.
Step 05Pre-OC
Notice & certificate
A durable notice goes in the meter box, and the installation certificate goes to your builder and certifier.
Step 06Handover
Owner advice
The owner gets simple care instructions and an inspection schedule so the system keeps doing its job for years.

Pricing
What sets the price of a barrier
Every build is different, so we don't guess. We price from your plans and give you one fixed written quote. Quoting is free.
- 01Slab area & perimeterBigger footprints need more material, more edge protection and more labour.
- 02System typeFull under-slab, perimeter-only, chemical and reticulation options are all priced differently.
- 03Number of penetrationsEach plumbing and electrical service through the slab needs its own collar.
- 04Site complexityRetaining walls, step-downs, sandstone and suspended floors add detailing.
- 05Number of visitsStaged installs follow your program. Multi-dwelling sites can often be combined.
- 06Site accessTight blocks, steep driveways and limited street frontage slow the set-out and add time on site.
After handover
Keeping the barrier working
A barrier only works while it stays intact and visible. Pass these on to the owner.
- Keep at least 75 mm of the slab edge exposed. Don't cover it with soil, mulch or paving.
- No garden beds or stacked timber against the house
- Keep weep holes clear of render and debris
- Fix leaking taps, downpipes and hot water units near the walls
- Ask the installer before drilling through the slab or adding pipes
- Book a timber pest inspection at least every 12 months

Jamisontown questions
Answered
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Does being close to the Nepean affect the barrier at Jamisontown?
It affects how much attention the perimeter gets. Damp river-flat soil stays attractive to foraging colonies for longer, so we make sure the slab edge is properly treated or shielded and that no section is left to be finished later. We also flag where future paving will cover treated soil, since a reticulation line solves that before the landscaper arrives.
We are knocking down a 1960s house here. Anything extra to plan for?
Old gardens are the main thing. Demolition often leaves stumps, buried timber and fill that already support activity, so the under-slab component and soil treatment carry more weight on a rebuild than on virgin ground. Booking the inspection and quote before demolition finishes gives us time to design the barrier around what is actually in the ground.
Can you work to a builder's program on a commercial slab?
Yes. Larger pads off Mulgoa Road have dozens of penetrations and a tighter program, so we confirm collar installation against the plumber's set-out and attend before the pour inspection rather than on pour day. Staged attendances are priced up front so the site manager knows exactly when we are booked in.
Does a new home need a termite barrier in NSW?
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.
What does a pre-construction barrier cost?
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.
