Lower North Shore · AS 3660.1
Under-slab membrane and collars installed to AS 3660.1 for Milsons Point apartment and mixed-use podium slabs, at the northern approach to the Sydney Harbour Bridge.
Quick answer
Yes, a new apartment or mixed-use building in Milsons Point needs a termite management system, since the suburb sits in a termite-prone part of North Sydney Council regardless of how dense the site is. 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 before the Occupation Certificate.
Termite barriers in Milsons Point
Milsons Point is one of Sydney's smallest and densest suburbs, about 2 km north of the CBD in the North Sydney Council area, sitting at the northern approach of the Sydney Harbour Bridge and home to Luna Park, which opened in 1935, and the North Sydney Olympic Pool. Milsons Point station, a heritage-listed stop on the North Shore line, and the ferry wharf make it a constant through-route for commuters and visitors, and almost every resident lives in an apartment or works in a mixed-use building. Our work here is almost entirely podium slabs and basement-level construction rather than standard house rebuilds.
On a site this dense, a termite barrier has to be planned around the building's scale rather than a typical suburban block. A large podium slab can carry dozens of plumbing, drainage and service penetrations feeding car parks, basements and multiple floors above, and every one of those penetrations needs a collar fitted correctly the first time. Harbour moisture keeps basement and lower-level ground damper than an inland site, conditions subterranean termites are as comfortable in as any other coastal pest, so ventilation and drainage detailing around the perimeter matter as much as the collar count itself.

Local conditions
Three conditions shape a Milsons Point barrier, and they all trace back to how dense and harbour-adjacent the site is.
Milsons Point's apartment and mixed-use sites typically pour one large basement and podium slab with dozens of plumbing and service penetrations. Every one needs its own collar and correctly lapped membrane, planned from the drawings before the pour.
Being right at the harbour's edge keeps basement and lower-level ground damper than an inland North Sydney site, conditions subterranean termites favour as much as any coastal pest. We factor that moisture into perimeter and drainage detailing.
Almost every Milsons Point site combines residential, retail and basement car parking on one footprint, so the barrier has to be planned around a complex, multi-level structure rather than a single house slab. We work from the full set of plans, not just the ground floor.
What we install here
We work on Milsons Point apartment and mixed-use podium slabs, including basement-level car parking and retail space beneath residential floors. We install under-slab membrane, collars and a physical or chemical perimeter matched to the slab design, with the collar count worked out from the plumbing and service drawings before the pour. One fixed quote from your plans covers every stage of a tightly staged inner-city build. We confirm access and timing with your builder before we start.
Local knowledge
Our Milsons Point work sits close to Milsons Point station and the ferry wharf, where dense mixed-use construction is the norm, and near Luna Park and the North Sydney Olympic Pool, where visitor numbers add to the general activity around any construction site. Given how compact the suburb is, most of our attention goes to harbour-edge moisture and the sheer number of penetrations on a typical podium slab.
Milsons Point is certified through North Sydney Council, which requires the standard termite documentation before issuing the Occupation Certificate: an installation certificate spells out which areas were treated, which products were used and the installer's licence number, while a durable notice is fixed inside the meter box. We supply both, along with product data suited to a multi-level building, as soon as the work is done.

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.

Milsons Point questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215Yes. Density does not change the NCC requirement, and a podium slab here usually carries far more penetrations than a house, so we work from the plumbing and service drawings to plan the collar count before the pour and cover the whole slab in one visit. That keeps the whole process simple for you and your builder.
It affects drainage and ventilation detailing more than the products themselves. Basement and lower-level ground near the harbour holds moisture longer, so we pay particular attention to that alongside the standard collars, membrane and perimeter installed to AS 3660.1. It also keeps your certifier's paperwork straightforward and complete. Feel free to ask us anything else not covered here.
We work directly with your builder's site program, since access and staging are tighter on a dense Milsons Point site than a suburban block. Collars and under-slab work still go in after the plumbing rough-in and before the pour, timed to your schedule. We are glad to answer further questions once we are on site.
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.
