3 1. WOVEN STAINLESS STEEL MESH INTRODUCTION Woven Stainless Steel Mesh is a building product/termite barrier that when installed into a new or existing building will provide long term protection to the building from hidden subterranean termites. Woven Stainless Steel Mesh is made from 316 marine grade stainless steel mesh which has very high corrosion resistance and will last for the life of the structure. HOW WOVEN STAINLESS STEEL MESH WORKS: The aperture size of the mesh will not allow termites to get through the mesh when installed in the structure in the installation details described in this manual. The idea of the mesh works in a similar manner as a regular fly screen mesh on the windows/doors of a house. The aperture size of the mesh of flyscreen is smaller than the insect, this method of extrusion of the insect has been known for many years. Woven Stainless Steel Mesh is designed to restrict hidden termite ingress into structures. Woven Stainless Steel Mesh is to be applied or placed between two termite resistant materials or between one termite resistant material to extend to the exterior of the structure. If any installation method detail is not mentioned within this manual this clause will suffice. The Woven Stainless Steel Mesh is supplied in various lengths and widths depending on the installation method into the building required. If at anytime after the installers course has been concluded and you require any assistance, contact your place of purchase for advice if you are not sure of what you need to do with any aspect of the product or installation.

5 3. WOVEN STAINLESS STEEL MESH QUALIFED INSTALLERS Only qualified installers trained by Australasian Institute of Pest Management Training are to install the Woven Stainless Steel Mesh termite barrier. Installers will also require appropriate licensing by State Government legislation eg. QBSA QLD, units 6b, 8b & 10b, 42a competency of pest control licence. Recognition of prior learning can also be considered. Site inspections sheets are to be completed upon installation of Woven Stainless Steel Mesh. Please contact The Bug Shop for a copy of this document. Particular notice should be made on the site inspection sheet of any termite nests within 50 metres of the proposed construction site of the dwelling or structure. It is recommended if a nest is located you contact the builder or homeowner with a treatment proposal to be carried out. PRODUCT WARRANTY: Woven Stainless Steel Mesh provides a written product warranty to the builder/homeowner for a period of 12 years with conditions applying. See Sample Warranty at the back of this manual. INTEGRATION WITH OTHER TERMITE BARRIER SYSTEMS INCLUDING SLABS: Woven Stainless Steel Mesh can be installed with other approved barrier systems complying with AS and current edition of BCA. If being installed in conjunction with concrete slabs as part of overall protection, the concrete must comply with A.S and AS Diagram 3.1: Exposed slab edge (Integration with concrete and slab edge exposure) (visual) Exposed slab edge Penetration Concrete slab barrier also Minimum clearance 75mm Woven Stainless steel mesh installation manual November 2012 Woven Stainless Steel collar protection Page 5 of 67

8 SLAB PENETRATIONS PROTECTION INSTALLATION METHODS: Once all plumbing pipes and PVC/Copper conduits have been installed the appropriate method of application Woven Stainless Steel Mesh must be carried out prior to pouring of concrete if this is the chosen method of installation. Prior to positioning the mesh and clamp to pipe it is important to apply Plasmite Termite Sealant or Plasmite Termite Epoxy to the area of clamp where the clamp thread tightens. This seals the mesh to the pipe for extra protection (seals up small gaps from clamp tightening). Screw clamp up of the required height, and make sure outer edge of Woven Stainless Steel Mesh is turned up min of 10mm for added effectiveness providing another angle embedded in concrete to deter termites. During concrete pour, the concrete will seal on top of the mesh and the turned up mesh will still embed into the concrete vertical. With copper pipe, remove any outer insulation from the copper pipe at height of moisture membrane or footing. Place a single strip of good quality electrical insulation tape around copper pipe prior to positioning the Woven Stainless Steel Mesh and use Plasmite Sealant or epoxy around the mesh and clamp prior to tightening the clamp. Please consult your trainer or point of purchase if you are not sure of this procedure. Woven Stainless steel mesh installation manual November 2012 Page 8 of 67

17 STEEL COLUMNS AND POLES 7. PENETRATIONS THROUGH THE MESH Usually Woven Stainless Steel Mesh is installed in cavities and other areas of the house where there are no pipes, columns or poles that need to pass through the mesh barrier. Occasionally though you will need to provide a penetration such as a column or pole through the barrier with Woven Stainless Steel Mesh. Each situation needs to be handled using lateral thinking to solve the problem of how to maintain the barrier? A situation that may arise, particularly for larger buildings, is where the steel pole or column is secured to the footing to support the roof or suspended floor above. Woven Stainless steel mesh Ground level PROCEDURE: 1. Roll the mesh past the column for approximately one metre. Locate where then the centre of the column meets the mesh and cut the mesh at that point. This cut in the mesh is the same criss-cross method used for service penetrations. (see diagram 4.2) 2. Fold the mesh around the column and rejoin the entry cut with a simple fold. 3. Prepare a parging mixture and apply it to the surface of the pole. 4. Tightly fasten the mesh with either a clamp, if the cavity penetration is a pole. 5. Apply your parging mixture (sealant/epoxy/termortar) over the outside of your penetration forcing the parging through the mesh as much as possible. Note that the clamp may not be sufficient to seal this point of entry, but its use is designed to hold the mesh in place until the parging sets and seals the mesh to the column.

22 9. TERMITE CAP INSTALLATION FOR POSTS OR STUMPS This installation type applies only to Woven Stainless Steel Mesh installations where termite resistant mesh is installed as a cap on top of posts/piers/stumps which support structures on the ground (stump homes for example) and isolates the structure from the substructure. This type of installation has traditionally been called ant caps. This installation prevents termites from directly attacking timber above the termite cap by forcing termites to come outside the post/pier/stump to attack timber above. Termies having to build over the termite cap are usually deterred or at least easily detected on inspection. The properties of the Woven Stainless Steel Mesh makes it extremely difficult, if not impossille, for termites to build their necessary mud tubes (galleries) over the termite resistant mesh. We believe Woven Stainless Steel Mesh caps are superior to the traditional galvanised sheet metal termite caps because the mesh is flexible, smooth, pervious and a deterrent for termites building mud tubes over it.

25 10. ANT CAPPING SUSPENDED FLOOR 1. Brickwork needs to be complete to underside of bearers or floor joints. It is preferable to position the mesh one course below the top of the support pier as this provides a more secure installation. Placing the mesh on top of the pier is the more likely location given the difficulty in having brickies leave out the final course. In this position it is necessary for the builder to place a strip of Hardi-Flex (or a simular tough waterproof material) to minimise damage to the timbers from moisture rising through the brickwork. 2. Mesh is installed continuously on all foundation walls or structures and extends at least 80mm 100mm from the inner-side of the foundation. 3. All plumbing needs a collar of mesh at least 400mm from ground level. 4. When adjoining strips of mesh to each other you can use the fold method or overlap method using sealant or parge/epoxy (Two lines of sealant or parge/epoxy is required when using the overlap method). If you are not sure with the meaning of the above statement, contact your supplier. This installation type applies only to installations where termite resistant mesh is installed as termite strip shielding for foundation walls and piers in such a manner that the structure is isolated from the substructure. This installation prevents termites from directly attacking timber above the termite strip shielding by forcing termites to build over the shielding. Termites having to build over the termite cap are usually deterred or at least easily detected on inspection. The properties of the Woven Stainless Steel Mesh makes it extremely difficult, for termites to build their necessary mud tubes (galleries) over the termite resistant mesh. We believe Woven Stainless Steel Mesh caps are superior to the traditional galvanised sheet metal termite caps because the mesh is flexible, smooth, pervious and a deterrent for termites building mud tubes over it.

34 12. CONNOLLY KEY JOINT INSTALLATION This is where a key joint is formed in the concrete slab and the pegs and formwork are not removed when the concrete is poured. This creates entry points around the pegs and on both of the formwork. To overcome this problem, the mesh needs to be formed in the manner discussed in Section steel columns and poles using 400mm wide mesh. The installer needs to be on site when the pegs and formwork are in final position. The formed key joint panels need to be removed from the pegs*. The mesh is placed on top of the pegs and cut around each peg and pushed down onto the waterproof membrane and securely clamped. Be sure to allow enough mesh to follow all the contours of the ground and leave enough mesh for joining the perimeter mesh. Place the required length and width of plastic membrane on top of the mesh. Finally the formwork should then be carefully placed back on the pegs. *NOTE: DO NOT DISTURB THE PEGS EXCESSIVELY.

The area where the nominated saw cut/expansion joint is to be located should be marked or indicated to the Woven Stainless Steel Mesh installer. 3. The mesh is formed to the shape required and positioned so that the form boards are placed on top of the mesh centre. The mesh is then placed in an L Shape so that the pegs holding the form boards don t damage the mesh. 4. The concrete is poured and the pegs and boards are removed. 5. The installer then repositions the exposed mesh to be encased in the next pour. Diagram 15.1: Various options (Joints) in slabs Woven Stainless steel mesh Ground level Diagram 15.2: SLAB SLAB Waterproof Membrane Woven Stainless steel mesh November 2012 Page 39 of 67

40 Control joints are cast or cut into concrete slabs where the slab is too large to either be poured in one stage or where structural integrity needs consideration. Control joints allow for movement of the slab during curing. This joint is a common termite entry point. In this installation a strip of termite resistant mesh is formed down the length of the joint to prevent termite entry through this gap. The Woven Stainless Steel Mesh forms a physical barrier that builds our termites. Correct installation is essential to achieve an effective barrier. To ensure the best possible installation, the Woven Stainless Steel Mesh is only available through franchised companies employing specialist installers who have been through a comprehensive training and accreditation programme. The Woven Stainless Steel Mesh can only keep out termites if it is complete and not damaged. If any of the following trades on the site damage or move the mesh, clamps or parging mix then a termite entry point could occur. The site supervisor should immediately contact the Woven Stainless Steel Mesh installer if there is damage to the system of if modifications to the design of the house are made. If any of the trades are uncertain if their work could damage any part of the barrier, then they should contact their local Woven Stainless Steel Mesh office for advice. Finally, it is strongly recommended that a visual assessment by a competent person be carried out every 12 months to ensure nothing has bridge the Woven Stainless Steel Mesh. More frequent inspections, 3 6 monthly, are also recommended in more well known termite prone areas. NOTE: Woven Stainless Steel Mesh may also be applied to control joint after concrete pour, as below.

41 16. SOCK/BOOT INSTALLATION FORPOLES, POSTS & FENCES - Stumps, poles and any other timber which needs to be placed in the ground can be protected from subterranean termites with a sock or boot of mesh. It is not necessary to have the sock tightly fitted to the stump, in fact a loose fitting sock ma cause difficulty for the termites to sustain a gallery up the side of the mesh and is probably the preferred option. This installation restricts termites from directly attacking the timber post or from entering the post or main structure via splits or cracks in the wood. Termite resistant mesh is formed into a continuous boot or sock which is pulled over the end of the pole or post which is to be set into the ground. The edges of the mesh are joined at the side and at the bottom of the boot by a double lapjoint. The mesh should extend above the soil level to a height of at least 100mm. The Woven Stainless Steel Mesh forms physical barrier that builds out termites. Correct installation is essential to achieve an effective barrier. To ensure the best possible installation, the Woven Stainless Steel Mesh is only available through franchised companies employing specialist installers who have been through a comprehensive training and accreditation programme.

42 17. INSTALLATION OF CABLE SHIELDING This specification applies to installation where termite resistant mesh is installed as termite cable shielding. This installation prevents termites from attacking power and telecommunication cables. Termite attacks of this type, especially telecommunication cables are extremely difficult to find and expensive to correct. The Woven Stainless Steel Mesh forms a physical barrier that builds out termites. Correct installation is essential to achieve an effective barrier. To ensure the best possible installation, the Woven Stainless Steel Mesh is only available through franchised companies employing specialist installers who have been through a comprehensive training and accreditation programme. Woven Stainless Steel Mesh cable shielding should be continuous by either by the use of standard lap joints or by winding the mesh continuously over the cable. Cable Woven Stainless steel mesh.
