⚙️ Physical termite barrier
Stainless steel mesh / graded crushed rock
New construction only
🧪 Chemical soil barrier
Non repellent termiticide treated zone
Existing homes any age
How
A continuous fine stainless steel mesh or graded crushed rock layer installed at foundation level during construction the mesh aperture is too small for termites to pass through undetected.
How
A continuous treated zone created in the soil around and under the building, using trenching, rodding, and slab drilling where required termites cannot detect the chemical and are killed on contact.
Lifespan
Permanent does not degrade, no chemical renewal required for the life of the building.
Lifespan
8 to 10 years under normal Melbourne soil conditions, then requires renewal.
Installation
Must be installed during construction at slab or foundation stage. Cannot be retrofitted to a completed building without major excavation.
Installation
Can be installed on any existing home at any time, the standard option for established Melbourne properties.
Cost
$2,500–$6,000 during construction significantly cheaper than retrofitting protection after the fact.
Cost
$1,500–$3,500 depending on perimeter length and soil access complexity.
Building new or renovating
Install physical barrier at foundation stage
Far cheaper and more permanent when installed during construction retrofitting requires excavation that costs more than the original installation would have.
Existing home, no current barrier
Install chemical soil barrier now
The only practical option for an already built home applied without major excavation, renewed every 8-10 years to maintain protection.
🏠 Building perimeter
Continuous treated or physical zone around the entire foundation line the primary defence against soil-based termite entry.
🚪 Slab penetrations
Pipe penetrations, expansion joints, and service entries through concrete slabs common gap points requiring drilling and injection.
🛁 Wet area plumbing
Bathroom and laundry plumbing penetrations moisture prone zones that are also common termite entry points.
🪴 Garden bed contact points
Where garden beds or soil contact the building above barrier level a common way termites bypass an otherwise intact barrier.
$1,500 – $3,500
Chemical soil barrier
Existing home, standard perimeter quoted after site inspection.
$2,500 – $6,000
Physical mesh barrier
New construction installed at foundation stage, depends on footprint.
From $1,200
