1. Read and translate the text protection of buildings from subterranean termites

When building (new buildings or additions) is exploited, you are required to provide Termite protection.

Complying with building regulations. Two options are available: 1. Provide barriers against Termite infestation to protect the whole building  2. Using Termite resistant materials for all structural elements (partial solution only)

To comply with the Building Code of Australia protection should be provided in accordance with the relevant Australian Standards (AS 3660) which describe protection options that may utilise physical barriers, Termite resistant materials or combinations of these options.

Protecting a building from Termite attack

Chemical Barriers The use of chemical barriers to control Termites in buildings requires licensed operators. Chemical barriers must be complete and continuous and be maintained that way. Good site preparation is needed to ensure uniform distribution of the chemical. Chemical barriers for Termite infestation have come a long way since their introduction and can now be used as an environmentally-friendly alternative.

Physical Barriers Woven stainless steel mesh - this system consists of a fire woven marine grade stainless steel mesh, which is used as a physical barrier. The mesh is too small for Termites to pass through and too hard for them to chew through. 

Graded stone particles - consists of finely graded stone particles, the proportion and dimensions of which are strictly controlled. Graded stone particles can be installed under concrete slabs and suspended floor type systems to form a continuous Termite barrier in conjunction with other Termite barrier systems and building practices. The graded stone must be placed in accordance with the criteria listed in Australian Standard AS3660.1. 

Sheet materials - usually formed from galvanised sheet metal 0.5mm thick, the Termite shield delays and impedes the passage of Termites. Ant Caps must be placed at all entry points to a building in order to form an integrated system. In the case of raised floor construction, this would mean shields on top of stumps and within any base structure walling.

Visual Barriers which are strictly controlled. Graded stone particles can be installed under concrete slabs and suspended floor type systems to form a continuous Termite barrier in conjunction with other Termite barrier systems and building practices. The graded stone must be placed in accordance with the criteria listed in Australian Standard AS3660.1.

Visual Barriers Alternatively you may elect to use a combination of the above mentioned systems to protect your home.

It should be noted that regardless of the type of system installed, there are no guarantees in keeping a building free from Termite attack. Standards and codes only minimise the risk. As longevity of a building is an essential element for an owner, there are several options of treatments to choose from and must make a concerted effort in determining the most efficient and effective solution for protection against Termite infestation.

In all cases one must ensure that inspections are carried out on a regular basis in order to monitor potential activity of Termites.
