Pre-Construction Termite Barriers Sydney
AS 3660.1 Compliant Barriers for New Builds, Extensions & Renovations.
Planning a new build in Sydney? Protect your investment from the ground up with Pest Elite’s pre-construction termite barrier services. We install chemical soil treatments, Kordon and Homeguard physical barriers, and reticulation systems during construction — with same-day AS 3660.1 compliance certificates for your certifier.
Pre-Construction Termite Barrier Systems
Whether you are a homeowner, developer, or builder, Pest Elite delivers compliant termite barrier installations tailored to your site and construction method. We work directly with site supervisors to meet pour dates and framing milestones.
Chemical Soil Barriers
- Termidor (fipronil) — applied to prepared soil and footings before the slab is poured, creating a continuous treated zone beneath the building footprint.
- Biflex (bifenthrin) — suited to certain soil profiles and construction types where a repellent barrier is specified.
- Altriset — reduced-risk option for sites with groundwater sensitivity.
Physical Barriers
- Kordon membrane — deltamethrin-treated sheeting at slab junctions, wall bases, and penetrations.
- Homeguard sheeting — stainless steel mesh or particle barrier for green building programmes.
- Reticulation systems — future re-treatment without excavation on difficult-access sites.
Barrier Installation at Every Construction Stage
We schedule around your build timeline — not the other way around
Pre-Pour Soil Treatment
Termidor or Biflex applied to prepared soil and footings before the concrete slab is poured. Creates a continuous treated zone beneath the entire building footprint.
Post-Pour Perimeter
After the slab sets, we treat the full perimeter at the slab edge and all service penetrations — pipe chases, conduit entries, and cable ducts.
Physical Barrier Install
Kordon or Homeguard sheeting installed at slab junctions, wall bases, and penetrations where physical exclusion is specified in the treatment plan.
Certificate Issued
AS 3660.1 compliance certificate emailed same day — covering product used, application rates, treated zones, and installer credentials.
Which Pre-Construction Barrier Is Right for Your Build?
We recommend after reviewing your plans and site conditions

| Kordon Membrane | Where future soil access is limited | Not required (physical) | Life of building | ✓ Yes |
| Homeguard Sheeting | Junctions, penetrations, slab edges | Not required (physical) | Life of building | ✓ Yes |
| Reticulation System | Future-proofing, difficult access sites | Pipe injection — no excavation | Product dependent | ✓ Yes |

Frequently Asked Questions
Is a pre-construction termite barrier mandatory in Sydney?
Yes. Australian Standard AS 3660.1 requires a compliant termite management system for all new Class 1 and Class 10 buildings. This is checked at the occupancy certificate stage by your private certifier or council inspector.
What is the difference between pre-construction barriers and post-build barriers?
Pre-construction barriers are installed during the build — chemical treatment before the slab pour, physical membranes at junctions, and perimeter treatment at the slab edge. Post-build termite barriers are installed on existing homes via trenching and injection drilling.
Can you work around our construction schedule?
Yes. We coordinate directly with your site supervisor to schedule treatments around pour dates and framing stages. We aim to be on-site within 24–48 hours of your request.
Do you issue the compliance certificate the same day?
Yes. The AS 3660.1 certificate is emailed on the day of treatment — covering product, application rates, treated areas, and installer credentials. Your certifier can accept this directly.
