Eastern Suburbs · AS 3660.1
Collars, membrane and perimeter barriers installed to the builder's program across Randwick, from terrace rebuilds near The Spot to unit developments close to the racecourse and health campus.
Quick answer
Yes. A rebuilt terrace, unit building or new home in Randwick needs an NCC termite management system installed to AS 3660.1. Collars and under-slab work go in before the concrete pour. The durable notice for the meter box and an installation certificate for the Randwick City Council certifier are both required before the Occupation Certificate is issued.
Termite barriers in Randwick
Randwick is one of Sydney's older suburbs and the home of Randwick City Council, about 5.8 km south-east of the CBD in postcode 2031. Victorian and Federation houses, terraces and semis line many streets, alongside interwar and modern unit blocks. The suburb includes Royal Randwick Racecourse, the Prince of Wales and other hospitals on the Randwick health campus, and busy shopping streets around Randwick Junction and The Spot, with UNSW sitting just to the west. Our work spans terrace rebuilds on the older streets and unit or institutional construction closer to the racecourse and hospital precinct.
That mix of old housing and large institutional land uses gives Randwick a wide spread of barrier work. Terraces and semis share walls and roof spaces, so a slab poured for a rebuild sits close to whatever protection, or lack of it, exists next door. Unit developments and any new building on the racecourse or health campus grounds carry a different scale of construction, often with basement levels and a large number of service penetrations on a single slab. We size the job to the building rather than running the same system regardless of scale.

Local conditions
Three things shape termite risk in Randwick, tied to its older terraces and its large institutional precincts.
Randwick's terraces and semis sit close together, sharing walls and sometimes roof space, so a colony active in one house can already be pressing against the footings of the next. We detail the barrier hard against that shared wall junction on any terrace rebuild.
Royal Randwick Racecourse and the hospitals on the health campus occupy a large share of the suburb, and any new building on that institutional land, including basement levels, still needs a fully compliant termite management system. Collar counts and access scheduling are planned around each site's own construction program.
Victorian and Federation homes on Randwick's residential streets often have timber floors and roof framing that termites can reach once any original protection has failed. A knockdown rebuild on one of these blocks needs a fresh, documented termite management system.
What we install here
We work on Randwick terrace rebuilds and renovations on the older residential streets, unit developments near Randwick Junction and The Spot, and construction on the racecourse and health campus grounds where compliance documentation matters as much as the install. Slabs on terrace sites are usually small and constrained by party walls, while institutional and unit sites need collar counts planned from the plans well before we arrive. You get one fixed written quote covering every stage, and we attend in stages so a barrier visit never holds up a pour.
Local knowledge
Our Randwick work runs from the terrace rows near Royal Randwick Shopping Centre and Alison Park, where party-wall detailing matters most, out toward the racecourse and health campus precinct, where larger institutional builds drive collar scheduling. Around Fred Hollows Reserve, established trees and garden beds sit close to a number of residential rebuild sites. We check institutional and residential sites with the same care, adjusting only for scale.
Randwick City Council requires a durable notice for the meter box and a signed installer's certificate, covering the products, the coverage and the licence, before it will grant an Occupation Certificate for a Randwick property. We prepare both once our stage of the work is done, whether the job is a terrace, a unit or a larger institutional build.

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.
Missing durable notices and unclear install records are a common reason Occupation Certificates get held up. We hand everything over together so your certifier has it all in one go.

Randwick questions

+61 450 515 215Yes. A rebuilt or substantially extended terrace is treated as new work under the NCC, so it needs its own termite management system installed to AS 3660.1, detailed hard against any shared party wall. We check what protection, if any, the original terrace has before finalising the plan. We also confirm access arrangements with any neighbouring property before starting work.
The same NCC requirement applies, but the job is scaled differently. Institutional builds on this land can include basement levels and a large number of service penetrations, so collar counts and scheduling around a busy construction program matter more than they would on a single terrace. We confirm access and scheduling with the site's project manager well ahead of our visit.
Yes. Original timber floors and roof framing in Victorian and Federation homes are well past the point where any original protection can be relied on. We treat a knockdown rebuild as a fresh job, with its own documented termite management system tied into the existing structure where relevant. We check the sub-floor condition on site before finalising the scope of work.
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.
