Sutherland Shire · AS 3660.1
Perimeter and under-slab termite systems installed on Dolans Bay's waterfront blocks in postcode 2229, from the moorings off Wally's Wharf to the bush edge at Wattlebird Reserve.
Quick answer
Dolans Bay sits in termite-prone Sutherland Shire, so yes, a new home, boatshed or other outbuilding needs a termite management system that satisfies the National Construction Code. Physical and chemical elements are installed before the slab goes down, with a collar fitted at every penetration, and once that's finished, the certifier receives the paperwork: an installation certificate plus a meter-box durable notice, both needed before occupation is approved.
Termite barriers in Dolans Bay
Dolans Bay is one of the smaller suburbs in the Sutherland Shire, about 22.9 km south of the CBD in postcode 2229, sitting on the north shore of the Port Hacking estuary. Homes line the streets above and along the water, several with their own boatsheds looking over the sheltered cove of Burraneer Bay, and Wally's Wharf is a well-known spot on the foreshore. With little vacant land left in such a small suburb, most work here is knockdown rebuilds and renovations on established waterfront blocks, along with the occasional granny flat or deck addition. Every one of those still triggers the requirement for a compliant termite system, fitted before the concrete goes in.
Being surrounded by water on so many sides shapes the ground here more than anything else. Boatsheds, timber decking and sea walls sit right at the waterline, and dense foreshore gardens above them hold moisture long after the tide has gone out, conditions that suit subterranean termites working in from a neighbouring block or a nearby reserve. Wattlebird Bushland Reserve, close to the suburb, adds another source of established activity on the landward side. On a site like this a barrier has to run from the waterline up to the roof rather than stopping at a single straight edge, since boatsheds, retaining walls and sloping gardens all create their own junctions.

Local conditions
Three things drive termite pressure on a Dolans Bay block, and most of them come from the water.
Boatsheds, jetties and timber decking built close to the water stay damp for long stretches, and that moisture supports termite activity working in from the shoreline. We treat these structures as part of the site rather than an afterthought, running collars and membrane wherever timber meets ground or water.
Burraneer Bay's sheltered waters keep foreshore gardens lush and shaded, and that dense, damp planting holds moisture close to house slabs well after rain has passed. Sloping gardens above the water also mean more retaining walls, each one a junction the barrier has to be detailed around.
Wattlebird Bushland Reserve sits close enough to Dolans Bay to bring established termite activity in from that direction as well as from the water. Blocks between the reserve and the foreshore effectively face pressure from both sides, so we run a full perimeter rather than a partial one.
What we install here
Dolans Bay work is mostly knockdown rebuilds and renovations on established waterfront blocks, along with granny flats, deck additions and the occasional new boatshed. Suspended floors and piers are common close to the water, while blocks further up the slope are more likely to use a standard slab. We quote the whole job from your plans as one fixed price and treat boatsheds, retaining walls and terraced gardens as part of the same barrier, attending in stages around your builder's program so nothing on a tight foreshore site is held up.
Local knowledge
Wally's Wharf and the moorings of Burraneer Bay sit at the centre of most Dolans Bay addresses, and waterfront blocks near them get particular attention to boatsheds, sea walls and timber decking, all places moisture collects. Wattlebird Bushland Reserve, about 0.8 km away, and Carmen Place Reserve, closer still, bring established bush growth up to the edge of residential streets. Woolooware Golf Course, a couple of kilometres off, marks the wider district but has little bearing on foreshore blocks, where water is by far the bigger factor.
Sutherland Shire Council handles certification for Dolans Bay. Before they will sign the Occupation Certificate, two things go on file: a meter-box durable notice, and an installation certificate recording the products used, the zones treated and the licensed installer responsible. On waterfront sites we also note any boatshed, deck or retaining structure the system extends to, since these often sit outside a standard house footprint and certifiers want that spelled out.

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.

Dolans Bay questions
Still unsure? Call and talk it through with a licensed technician.
+61 450 515 215A boatshed built as part of a new residence or major renovation generally needs the same consideration as any other outbuilding under the termite management system, particularly where its timber sits close to the waterline. We assess each structure from the plans and work out collars and barrier placement wherever its framing touches soil or a slab edge.
We work from the retaining wall and landscaping plans before starting, since every terrace on a sloping Dolans Bay block forces the perimeter to step or turn rather than run in a straight line. Instead of pricing a single continuous strip, we cost and detail each junction on its own so the barrier still forms one unbroken line around the structure.
The system itself is the same, but blocks near the reserve get closer attention to the perimeter, since established bush on that side adds pressure on top of whatever comes from the water. Many owners on those blocks choose physical collars combined with a chemical treatment around the entire perimeter, with a reticulation line kept clear of any paving or landscaping planned over the treated zone.
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.
