Why pre construction

Termite protection starts before the slab is poured

Subterranean termites enter buildings through concealed pathways: slab penetrations, construction joints, and the gap between the slab edge and external walls. Once the home is finished, those entry points are hidden behind concrete, brickwork and cladding. The only time they can be fully protected is during construction.

The National Construction Code requires termite risk management for new homes built in designated termite risk areas, and AS 3660.1 is the Australian Standard that sets out how pre construction termite management systems must be designed and installed. South West Sydney sits within an active subterranean termite region, so your building certifier will expect a compliant system and a certificate of installation before sign off.

Installing protection at the build stage is also significantly cheaper than retrofitting. Once a home is complete, achieving equivalent protection means drilling, trenching and chemical soil treatment around an established structure. And the financial exposure is real: termite damage is generally not covered by standard Australian home insurance policies, so the build stage is the one cheap window you get to deal with the risk properly.

"Once the slab is down, you cannot get back to the penetrations. The time we spend collaring pipes and sealing joints before a pour saves the homeowner from ever needing to drill and trench around a finished house."

Barrier systems

Pre construction termite barrier systems we install

There is no single barrier that suits every site. The right system depends on your slab design, soil conditions, drainage and the builder's construction sequence.

Built into the structure

Physical barrier systems

Membranes and collars sealing slab penetrations, construction joints and the slab perimeter against concealed entry. Our lead technician, Ceyhan Kumru, holds Term-Seal accreditation (ts21317) for installing Term-Seal barrier products. No ongoing chemical component. You can also read about the Kordon termite barrier system.

Treated zone in the soil

Chemical soil treatment

The soil beneath and around the slab is treated so termites cannot tunnel through untreated ground to reach the building. Ceyhan is a Termidor Accredited Applicator (BASF, 2024), and all chemical work uses APVMA registered products at label rates.

Renewable protection

Reticulation systems

A termite reticulation system is a network of underground pipes installed before the pour, so the chemical barrier can be recharged in future without drilling or excavation. A practical choice for owners who want renewable protection for the life of the home.

Whichever system is installed, AS 3660 calls for regular inspections of the completed home. Our termite inspection service covers this once you have moved in, and many builds use a combination of physical and chemical protection.

    Every installation is documented with a certificate of installation and system details for your certifier and the homeowner's records, plus the durable notice for the meter box.

  • 3

    One local point of contact

    You deal directly with the licensed technician doing the work, not a call centre. Based locally, working the growth corridor estates every week.

"We had Gino and his team carry out a thorough pest inspection and termite barrier install at our property after an easy to arrange initial callout. All aspects of the work was clearly explained and carried out professionally. At the end we were left with extensive documentation on all aspects of the work."

"I first engaged the boys to install my termite barrier after my slab was poured. It was easy to communicate and he easily explained all stages of the job required by his team."

How it works

Installation in five stages

  • 1

    Site and plan review

    We review your slab design, site conditions and construction schedule, then recommend the system that fits. You get a written quote with the system specified.

  • 2

    Pre pour installation

    Penetration collars, joint protection and under slab components are installed before the concrete pour, inspected and photographed.

  • 3

    Perimeter completion

    Perimeter barrier or treated zone work is completed at the appropriate construction stage for your build type.

  • 4

    Certification and handover

    You receive the certificate of installation and system documentation for the certifier, plus durable notices for the meter box as required by AS 3660.1.

  • 5

    Ongoing protection

    Once the home is occupied, annual inspections keep the protection effective and the documentation current. Read more on termite prevention.

Pre construction questions

Questions builders and owners ask us

What is a pre construction termite barrier?+

A pre construction termite barrier is a physical or chemical termite management system installed during the building process to stop subterranean termites entering the finished home through concealed pathways. It protects slab penetrations, construction joints and the slab perimeter, which cannot be properly protected once construction is complete.

Is a termite barrier required for new homes in NSW?+

In most cases, yes. The National Construction Code requires termite risk management for new homes built in designated termite risk areas, and AS 3660.1 sets out how pre construction systems must be designed and installed. Your building certifier will ask for a certificate of installation before final sign off, and South West Sydney sits within an active subterranean termite region.

When is the barrier installed during the build?+

Installation happens in stages timed to your construction schedule. Penetration collars and under slab components go in before the concrete pour, and perimeter work is completed once the relevant wall or cladding stage is reached. We coordinate directly with your builder so the barrier never holds up the pour.

Should I choose a physical or chemical barrier?+

The right choice depends on your slab design, soil and site conditions. Physical membrane systems are built into the structure, contain no chemical component and suit most new builds, while chemical soil treatments and reticulation systems create a treated zone that can be recharged over time. We assess your plans and site before recommending a system, and many builds use a combination of both.

Do you work directly with builders?+

Yes. We work with builders, owner builders and developers across South West Sydney, scheduling each installation stage around your pour and wall dates and supplying the certificates of installation your certifier needs. You deal directly with the licensed technician carrying out the work.

How much does a pre construction termite barrier cost?+

Every barrier is quoted from your slab plan, so there is no fixed price list. The cost depends on the slab perimeter length, the number of penetrations, the system specified and how the install stages line up with your build. Send your plan and pour date through and we will give you a firm written price, usually the same day. Installing during construction is significantly cheaper than retrofitting equivalent protection after handover.

How long does a pre construction termite barrier last?+

It depends on the system installed. Physical barriers are built into the structure and are designed to protect for the life of the building element they seal, chemical treated zones have a defined effective life set by the product label, and reticulation systems are designed to be recharged on schedule. The manufacturer warranty details for your system are included in the handover documentation, and AS 3660 calls for regular inspections regardless of system type.

Can a termite barrier be installed after construction?+

Yes, but with more work and cost. An existing home can be protected with perimeter chemical treatment, drilling and trenching, or a retrofitted reticulation or baiting system. The result is effective protection, but the concealed entry points inside the slab can never be sealed the way they can during construction, which is why doing it before the pour is the better option whenever the choice exists.
