Inner South & City Fringe · AS 3660.1
Under-slab membrane and collars installed to AS 3660.1 for Mascot's apartment podium and rebuild sites, in the shadow of Sydney Airport and The Lakes Golf Course.
Quick answer
Yes, a new home or apartment building in Mascot needs a termite management system, since the suburb sits in a termite-prone part of Bayside Council and the NCC applies to every new dwelling regardless of how built-up the area 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.
Termite barriers in Mascot
Mascot is in the Bayside Council area, with a small part in the Inner West Council, about 7 km south of the Sydney CBD in postcode 2020, defined above all by Sydney Airport, its main landmark and employer, with Qantas headquartered on Coward Street. The Airport Line serves the area with several stations, and apartment blocks are concentrated around Mascot station, with older houses scattered through the remaining streets. Almost all of our work in Mascot is an apartment or townhouse podium slab, with the occasional knockdown rebuild on one of the older houses.
A single large podium slab near Mascot station can carry dozens of plumbing, drainage and service penetrations, and every one of them needs a collar fitted correctly the first time, because a barrier with the wrong number of gaps offers no real protection at all. Older houses on the remaining residential streets sit on more typical suburban ground, with the same soil conditions and timber concerns as any established Sydney block. The Lakes Golf Course adds irrigated turf near some boundaries, keeping that ground a little damper than the surrounding airport precinct.

Local conditions
Three things shape a Mascot termite barrier, and they have more to do with the type of slab than the ground beneath it.
Mascot's apartment and townhouse sites near the station typically pour one large slab with dozens of plumbing and service penetrations. Every one needs its own collar and correctly lapped membrane, so we plan the count from the drawings before the pour, not on the day.
The remaining detached houses scattered through Mascot sit on typical suburban soil, and a rebuild here needs the standard collars, under-slab work and perimeter to AS 3660.1, checked against any timber the previous house left behind.
The Lakes Golf Course keeps its fairways irrigated year round, and that moisture can carry a little further into nearby residential boundaries than the drier airport precinct around it. We factor that into perimeter detailing on sites close to the course.
What we install here
We work on Mascot apartment and townhouse podium slabs near the station, and knockdown rebuilds on the suburb's remaining detached houses. On multi-dwelling sites we take the collar count from the plumbing and service plans and attend in coordinated visits so the barrier does not hold up a tight construction program. One fixed quote from your plans covers every stage, whichever type of site you are building. We check site conditions properly before locking in a firm quote.
Local knowledge
Most of our Mascot work sits close to Mascot station and Robey Street Reserve, where apartment and townhouse podiums make up the bulk of new construction, and near The Lakes Golf Course, where irrigated fairways add moisture to nearby boundaries. Given how much of Mascot is built around Sydney Airport, our residential rebuild work is concentrated in the smaller pockets of older housing away from the main flight corridor.
Mascot is certified through Bayside Council, with a small section falling under the Inner West Council. Either certifier requires the standard termite documentation before issuing the Occupation Certificate: a durable notice fixed in the meter box, and an installation certificate naming the products used, the areas protected and the installer's licence. We supply both as soon as the barrier work is complete.

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.
Paperwork
A complete document set for the builder, the certifier and every future owner of the property.
A permanent notice in the meter box showing the system, install date, installer, any chemical's life expectancy and inspection advice.
For: certifier, owner, future owners
Written confirmation of the system and products used, the areas protected and our licence details.
For: builder, certifier, owner
Details of the physical system or termiticide installed, including safety data sheets for any chemicals.
For: builder, owner

Mascot questions

+61 450 515 215Yes. Any new residential building on termite-prone land needs a compliant system under the NCC, and Mascot's apartment podiums are no exception. We work from the plumbing and service drawings to plan the collar count before the pour, since these slabs carry many more penetrations than a house. Feel free to ask us anything else not covered here.
The same process as any residential rebuild: collars and under-slab work after the plumber's rough-in, then the perimeter before the site is landscaped. We also check any existing timber from the previous house during the quote, since that can already carry activity. We are glad to answer further questions once we are on site.
Not the products themselves, but it can affect scheduling and site access on tight inner-city blocks. We plan visits around your builder's program the same way we would on any dense site, and the collars, membrane and perimeter follow the same AS 3660.1 standard. This keeps everything properly documented for future reference too.
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.
