By doing this you limit the potential for termite damage to secondary and superficial elements which are easier to detect and cheaper to replace.
This option may reduce future ongoing costs anduses conventional materials and construction methods and does not rely on aregular maintenance system or professional liability policy.
Alternatively you can specify a physical orchemical barrier to be installed during construction. This should be inaccordance with the Australian Standard (AS3660.1) and should be finalisedduring the designs stage.
Some barriers will require ongoing inspections,maintenance and/or chemical replenishment.
The risk of attack can be reduced if effort ismade to remove tree stumps, roots, off-cuts and to properly consolidate thesoil to minimise cracks in concrete slabs.
Concrete is a very effective termite barrier ifit is correctly designed and constructed on properly prepared ground.
Termites eat any cellulose material whichbesides wood, can even include electrical cabling, plastics and other compositebuilding materials. While this does not include concrete, cracks as small as1.5mm may allow termites to find their way into a cavity such as walls andbeneath floors.
It is strongly recommended that before you buya house, you have an expert inspect it for termite activity.
The cost of a full report pales against thepotential expense of repairs.
Ensure you engage a properly qualified,experienced and insured pest inspector and ask them to report on the type, ageand condition of any termite management system which may be installed, and onthe materials used for critical structural elements.
Long-term management can be gained through theapplication of chemical or physical barriers (or both) to prevent termites frompenetrating the structure. An Australian Standard (AS3660.1) has been writtenon the subject.
The aim is to keep any cellulose material,especially timber, away from soil contact and to encourage termites to build amud tube out in the open where it can be seen during a regular, carefulinspection. Termite management systems are designed to stop concealed accessand force termites into the open where their mud tunnels can be more easilydetected.
Physical barriers range from small graded stoneparticles, stainless steel mesh and chemically impregnated composite products.Termite resistant materials are designed to protect the critical concealedstructural elements of your home, while ensuring a 'small target' for anytermite activity.
Ensure you use a product that has beencertified and complies with the Australian Standard and, most importantly, youmust arrange for appropriately qualified operators to carry out regularinspections.
You should also be fully informed about ongoingmaintenance requirements and the best pre- or post-construction options.
