What we need to quote
We need the architectural or slab plan, the slab type (raft, waffle pod, suspended), the address, a rough pour date, and engineering details for retaining walls or step-downs.
Pre-Construction Termite Barriers in Kingsdene 2118 — local technicians, fixed prices and a written report. Barriers are quoted off your plans and slab details.
Real, verified feedback from people we've helped — straight from Google.
What we cover in Kingsdene, and how quickly we can get there.
Postcode 2118 covers Kingsdene and the streets immediately around it. At about 19.1 km north-west of the CBD it falls in the Ryde & the Northern District, where we have vans out daily. We run Kingsdene on a regular route, and same-day attendance is usually available.
Around Kingsdene we work the pockets near Walter Brown Park, North Rocks Shopping Centre and North Rocks Shopping Centre most often, so the van is rarely far away when a job comes in.
We cover North Rocks, Carlingford and Oatlands on the same runs as Kingsdene, which helps when termite problems are moving between neighbouring properties. Most of the housing here shares a wall, a roof void or a sub-floor with something else, so we check what adjoins the property rather than treating it in isolation.
The termite calls we take from Kingsdene are mostly apartments and converted blocks where the kitchen backs onto a service riser. If yours is one of them, mention it when you ring 1300 313 373 - it changes what the technician brings.
Telopea station and Carlingford station are on the same round, which means every part of 2118 is within our area.
You get a confirmed time, not a window. We plan the 2118 run the day before, and if North Rocks or Carlingford is on the same round there is often an earlier slot going.
Most Kingsdene builds are waffle pod or raft, and the two are detailed differently at the edge. Tell us which it is when you send the plans and the quote will be right first time.
A compliant barrier does not mean termites can never reach the building. It means they cannot reach it concealed - they have to build workings where an inspection will find them. That is why the annual inspection is part of the system, not an upsell.
The system does not stop termites existing - it forces them into the open where an inspection will find them. That is why the annual check is part of the system rather than an optional extra.
Photos from our own Sydney installations, not stock images. We recommend the right mix for your slab design, site and budget.

A physical, termite-resistant membrane laid over the prepared ground ahead of the pour, covering the slab's entire footprint.

Each pipe, conduit and service crossing the slab is sealed with a collar - penetrations being the most common concealed entry.

Around the slab edge and up into the wall cavity, a physical barrier stops termites running hidden tunnels up the outside of the slab.

APVMA-registered termiticide applied to the soil, with the option of a reticulation pipe network so the barrier can be recharged later without digging.

For sloping or elevated sites, protection covering the piers, bearers and suspended timber floor.

Detailing for the complications Sydney blocks throw up: retaining walls, sandstone excavation, step-downs and cut-and-fill.
Once the slab is poured, the areas termites use most are sealed away for good.
Doing it now is far cheaper than retrofitting a system later, and cheaper again than repairing termite damage.
A compliant termite management system is required for new Class 1 homes and Class 10 outbuildings with termite-susceptible primary building elements.
Pipe penetrations and slab joints can only be fully protected before concrete covers them.
No post-construction treatment reaches under the slab. An under-slab system does.
No Occupation Certificate is issued without the installation certificate and durable notice going to the certifier.
Buyers, building inspectors and lenders all take comfort from documented, compliant termite protection.

Both approaches can comply with AS 3660.1. Many Sydney builds use a combination.
| System | How it works | Durability & upkeep | Best suited to |
|---|---|---|---|
| Physical membrane, mesh or graded stone | A termite-resistant layer (sheet, stainless mesh or graded stone particles) that termites can't chew through, laid under the slab or at the perimeter | Designed to last as long as the slab if it isn't disturbed. No chemical top-ups. | Slab-on-ground homes and owners who want a non-chemical option |
| Penetration collars | Each pipe and conduit through the slab is sealed with a physical collar | Long-lasting, assuming correct installation before the pour | Every slab, usually in combination with a perimeter system |
| Chemical soil barrier | A zone of termiticide-treated soil under and around the structure | Service life follows the product label and soil conditions; re-application is possible | Budget-sensitive builds and certain complex sites |
| Reticulation system | A pipe network put in ahead of paving, letting termiticide be pumped into the soil later | Rechargeable for as long as the building stands, without digging paths up | Homes enclosed by paving or landscaping |
| Baiting (post-construction) | Stations in the ground that monitor activity and eliminate the colony | They need servicing on a regular basis | Existing buildings - see termite control |
Termite barriers are installed in stages that follow the build, not in a single visit.
Plans and slab details to us, and you get a system recommendation plus a fixed price stage by stage.
Every service through the slab is collared first, then the under-slab membrane or chemical treatment goes down on the prepared site.
Perimeter and cavity barriers go in as the brickwork or cladding rises, so the slab edge is never left with a gap.
If specified, the chemical perimeter or reticulation system is finished around the completed building before paving and landscaping start.
The system is recorded on a durable notice in the meter box, and the installation certificate goes to both the builder and the certifier.
The owner receives maintenance advice and a recommended inspection schedule to keep the system effective.
| Document | What it is | Who needs it |
|---|---|---|
| Durable notice | A permanent notice fixed inside the meter box recording system, installation date, chemical life expectancy, installer and inspection advice | Certifier, owner and future owners |
| Installation certificate | Written confirmation covering the system and products used, the protected areas and the installer's licence | Builder, certifier, and the owner's own records |
| Product information | Specifications for the physical system or termiticide used, plus safety data sheets where chemicals are involved | Builder and owner |
| Maintenance & inspection advice | Guidance on keeping the barrier effective, with the AS 3660.2 recommended inspection frequency | Homeowner |
We need the architectural or slab plan, the slab type (raft, waffle pod, suspended), the address, a rough pour date, and engineering details for retaining walls or step-downs.
We work to the plumber's set-out and the concreter's program. Let us know when the services are in and collars are confirmed before the pour inspection.
Developers and volume builders get consistent pricing, a single point of contact and documentation for every lot or dwelling.
Delays at occupation certificate stage usually come down to a missing durable notice or unclear records. We provide the complete set at once.
A barrier only works if it stays intact and visible. Homeowners should follow these points for the life of the building.
| Factor | Why it matters |
|---|---|
| Slab area & perimeter length | A larger footprint requires more membrane, more perimeter work and more labour |
| Type of system | Pricing differs between full under-slab physical systems, perimeter-only systems, and chemical or reticulation options |
| Service penetrations | Every plumbing and electrical penetration through the slab has to be collared |
| How complex the site is | Retaining walls, step-downs, sandstone excavation and suspended floors all add detailing |
| Number of site visits | Staged installations follow the build program. Multi-dwelling sites may be combined. |

It is one of the few construction details that still matters commercially fifteen years later.
Reactive soil is the argument for a system that tolerates movement rather than a rigid one. We choose based on the soil report for the Kingsdene site, not on a default.
The assumption that a new build is low risk is backwards. New construction on previously vegetated land is exactly where we see early activity.
NSW licence 5122967, and installation work done to AS 3660.1.
Scheduled around the builder's program, so a barrier stage does not delay the pour.

Same-day attendance is usually available. Kingsdene sits roughly 19.1 km north-west of the CBD, inside our Ryde & the Northern District run, so we book a time and keep to it.
Most of this area is terrace, semi and converted block, and those share more than people realise - cavities, roof spaces, drainage. termites use all of it.
Terraces and semis that share walls, roof voids and drainage - so we look at what the property adjoins before deciding where product goes.
We do. A lot of our Kingsdene work is rentals and strata, so the report, the products used and the areas treated are all recorded in writing for whoever needs them.
Yes, applied correctly. Products are registered for this use, placed out of reach rather than across open surfaces, and you will know what to stay off and for how long.
In most cases you can stay. Where an area does need to be left clear it is for a couple of hours at most, and we say so before we start.
Between one and two hours covers the majority of jobs. We do not book so tightly that a technician has to cut a job short.
You get the AS 3660.1 certificate and the durable notice for the meter box. Call us if activity picks up again and we will arrange the return visit.
We cover the whole of Kingsdene, from the streets around North Rocks Shopping Centre out to the suburb boundary and on into North Rocks.
