Penrith & the Outer West · AS 3660.1
Perimeter termite barriers installed to AS 3660.1 for new homes and sheds on Llandilo's acreage blocks, between South Creek and the Wianamatta Nature Reserve bushland edge.
Quick answer
Yes, a new home or outbuilding on a Llandilo acreage block needs a termite management system, since the suburb sits in a termite-prone part of the City of Penrith and the NCC applies to sheds and outbuildings as well as houses. The system is installed to AS 3660.1, with collars and under-slab work completed before the pour, and the durable notice plus installation certificate supplied to your certifier.
Termite barriers in Llandilo
Llandilo is a small semi-rural locality in the City of Penrith, postcode 2747, about 47 km north-west of the Sydney CBD, lying between South Creek to the east, Cranebrook to the west and Berkshire Park to the north. Holdings here have been subdivided over time into blocks of roughly one to two acres, big enough for sheds, animals, vegetable gardens and open paddocks, and Llandilo Public School has served the area since 1866. A new home or shed on a block like this is usually built well back from the road, with its own septic, bore or dam, so our work covers more ground than a standard suburban lot.
South Creek and the surrounding creek flats keep soil damp on Llandilo's eastern side, and that moisture is exactly what subterranean termites look for when foraging toward a new slab. Wianamatta Nature Reserve adds a bushland edge nearby, with stumps and fallen timber that hold established colonies close to some properties. Sheds, chook pens, stacked timber and compost heaps on working acreage blocks give termites additional food sources right next to the house, so a barrier here has to account for outbuildings and yard structures, not just the main slab.

Local conditions
Three conditions set termite risk on a Llandilo acreage block apart from a standard suburban lot.
South Creek and the flats along it keep soil damper on Llandilo's eastern side than the surrounding growth corridor. Subterranean termites favour that moisture when foraging toward a new house or shed slab near the creek.
Wianamatta Nature Reserve sits close to parts of Llandilo, holding termite colonies in old stumps and fallen timber that can move toward nearby acreage blocks. Properties near the reserve boundary get a full perimeter rather than a token strip.
One to two acre blocks in Llandilo typically carry sheds, chook pens, stacked timber and stock yards that feed termite activity close to the house. We treat the whole property, starting outside, rather than sizing the barrier to the house slab alone.
What we install here
We install perimeter and under-slab termite systems for new homes, granny flats and outbuildings on Llandilo's acreage blocks, sized to whatever slab design your builder is using and to the sheds, stables or garages that sit near the main house. Because access and site conditions vary block to block, we quote from your plans and a site look, and schedule the visit around your plumber's rough-in so it does not hold up the pour.
Local knowledge
Our Llandilo work is spread across acreage blocks between South Creek and Wianamatta Nature Reserve, where bushland edges and creek flats both bring termite pressure toward new construction. Closer to Jordan Springs Shopping Centre and Dunheved Golf Club, properties sit nearer the newer estates on Llandilo's fringe, with irrigated turf adding moisture of its own. Wherever the block sits, we inspect any existing shed or outbuilding for termite activity before recommending a system for the new work.
Llandilo is certified through the City of Penrith, which requires the same termite documentation for a new home or outbuilding on an acreage block as anywhere else: a durable notice fixed in the meter box, and an installation certificate naming the products used, the areas protected and the installer's licence, both needed before the Occupation Certificate is issued. We provide both, along with maintenance advice suited to a rural-residential property.

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.

Llandilo questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Any new outbuilding covered by the NCC on termite-prone land needs its own compliant system, and on an acreage block a shed close to the house is often the first place termites reach before the main building. We size collars and perimeter work to cover both. Reach out early so we can lock in a suitable date.
Yes. Creek-flat soil holds moisture longer than higher ground further from the water, and that favours subterranean termites, so blocks near South Creek usually get a full physical perimeter rather than a minimal strip, with attention to any low, damp corner of the site. We keep a copy of every certificate on file for later.
We ask about driveway length, gates and any livestock on site when we quote, since acreage blocks can need more planning than a standard suburban lot. Collars and under-slab work still go in after the plumber's rough-in and before the pour, timed around your builder's program. That keeps the whole process simple for you and your builder.
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.
