A physical termite barrier is a permanent layer built into your home that termites cannot chew through, tunnel around or carry away. It is installed under and around the slab during construction, or fitted to the slab edge, pipe penetrations and weep holes of an existing home. Sherlock Integrated Pest Management installs physical barriers across the Perth metro area to AS 3660.1, and every installation comes with a written certificate and a durable notice for your meter box.
High-strength plastic membranes are infused with insect-resistant properties and installed under slabs or around retaining walls. These flexible sheets create an impermeable seal against termites and moisture.
This system uses finely woven, corrosion-resistant stainless-steel mesh installed around service pipes and slab perimeters. Termites can’t chew through or squeeze between the tiny gaps, providing lifelong protection that doesn’t degrade over time.
These systems use precisely sized, hard granules placed around foundations. Termites can’t move or tunnel through the tightly packed stones, ensuring natural, eco-friendly termite protection that also enhances drainage.
The National Construction Code requires a termite management system in every new home built in Perth, and a physical barrier is one of the accepted methods. It has to go in before the slab is poured, so the builder or owner builder books us at the plumbing rough-in stage. Most of our new build work is in the northern corridor estates around Alkimos, Eglinton, Yanchep, Two Rocks, Butler and Banksia Grove.
A full under slab barrier cannot be retrofitted, but the entry points termites actually use can be. We fit stainless steel mesh or termite resistant DPC to the exposed slab edge, pipe collars and weep holes. For complete perimeter protection this is usually paired with a chemical termite barrier or a termite reticulation system, and we will tell you which combination suits your home before quoting.
A new slab for an extension, alfresco or granny flat creates a join with the old slab, and a bathroom or kitchen renovation often cuts new pipe penetrations through the existing one. Both create concealed entry points that were never protected. We fit mesh or sheeting at the new penetrations and along the join, and we check that new paving or concrete paths have not covered the slab edge inspection zone.

A physical termite barrier is a durable layer of stainless steel mesh, termite resistant sheeting or graded stone built into the structure of a home to block the concealed paths termites use to get in. Unlike a chemical termite barrier, which creates a treated zone in the soil that needs renewing, a physical barrier is a permanent part of the building. Both are recognised termite management systems under AS 3660.1, and many Perth homes use one of each.
Booking your pest control service is quick and easy. Simply call our Perth office or book online, and our team will arrange an inspection at a time that suits your business schedule.
Under slab systems go in after plumbing rough-in and before the concrete pour. Perimeter and penetration systems on existing homes are usually done in a single visit. Every installation follows AS 3660.1 and the manufacturer's method.
Every installation undergoes detailed inspection and quality verification. Upon completion, we provide a compliance certificate confirming that your barrier meets Australian Standards.
Our licensed experts carry out the treatment efficiently using proven, eco-friendly methods. Once pests are eliminated, we ensure your workplace remains hygienic, and safe.
Our technicians are fully licensed and insured to install physical termite barriers across Perth. We follow Australian Standards and local building codes
Before and after installation, we carry out a complete site inspection and provide a detailed report outlining the work completed, barrier locations, and maintenance recommendations.
We only use Australian-approved termite barrier materials such as stainless-steel mesh, graded stone, and polymer sheeting that meet AS 3660.1 standards.
we brief property owners and builders on barrier maintenance, inspection schedules, and best practices to ensure continued effectiveness over time.

Physical barriers are designed to stop subterranean termites, which are the main threat in WA. The most destructive species in Perth is Coptotermes acinaciformis, followed by Schedorhinotermes intermedius and Nasutitermes exitiosus. All three attack from below ground, it blocks their only concealed entry path into your home.
Yes. The National Construction Code requires a termite management system in new homes across the Perth metropolitan area, installed to AS 3660.1, with a durable notice fixed in the meter box. A physical barrier, a chemical barrier or a reticulation system all satisfy the requirement. Your builder will usually specify which one.
Yes, but with limitations. Full under-slab barriers like Kordon can only be installed before the slab pour. For existing homes, we retrofit barriers around perimeters, weep holes, pipe penetrations, and slab edges using products like Termimesh collars and Homeguard DPC.
Stainless steel mesh and graded stone are designed to last the life of the building because there is nothing in them to break down. Termite-resistant sheeting carries a manufacturer’s warranty period. Every system’s warranty depends on an inspection at least every 12 months under AS 3660.2.
Stainless steel mesh and graded stone are used. Termite-resistant sheeting and DPC are impregnated with a termiticide, so they are not. If a chemical-free system matters to you, tell us when you book, and we will design around mesh and stone.
