How does the Termimesh System work?
The Termimesh System is a totally engineered stainless steel physical barrier and will not require or depend on any “traditional poisonous chemicals” for the primary protection of the building against subterranean termites.
The Termimesh System is not applied “like chemicals” which is sprayed onto the soil beneath the building slab and under all the aprons.
The Termimesh System is not time or weather restrictive and does not require NEA’s approval and as such will not impede any critical path construction activity.
The Termimesh System is primarily dependent on the marine grade stainless steel mesh, functioning as the safe and long term physical termite control to keep termites out.
The Termimesh System is designed to “block” all the hidden “routes” which termites generally prefer to enter any building for the long term. The termites may then come out into the open and become visible to be dealt with.
1. Termimesh Barrier in Slab-on-Ground Construction
The Termimesh barrier is installed at the locations where the termites will attempt to gain “hidden entry” into the buildings. Many surveys and extensive evidence have shown that the vast majority of termite entries occur at the following places:
Openings in the slab are usually hidden from view once the building is complete.
Placing the physical barrier into the concrete slab openings and joints prevent termites from entering buildings and destroying skirtings, roof members, windows, doorframes and cupboards. A well designed concrete slab provides a solid barrier to termites and forms part of the Termimesh System.
A sound concrete slab should not develop cracks with widths as great as 1mm over the life of the building. Most concrete wall and floor slab will only develop hairline cracks, which are too small for termites to enter.
If the concrete slab do develop a large crack sufficiently wide enough for termites to gain entry, then we will have only to provide a “post construction” Termimesh CJ installation over the “crack”.
The stainless steel mesh is so flexible it can be molded to fit the building, leaving no gaps for termites to penetrate. Special stainless steel clamps are used to secure the mesh around pipes and conduits preventing termites penetrating at these locations.
2. Termimesh Barrier in Basement Construction
As with Slab on ground construction
- All vertical and horizontal cold joints, control joints , expansion joints
- Around the pipes that pass through the wall and floor slab
- In through the pipes
- And perimeter wall junctions between basement wall and first storey slab
As with all basements, it is likely that the basement structure are in high water table.
The Singapore’s National Environment Agency has stipulated that for all high water table areas, “all Termiticides are not allowed”.
Termite colonies do thrive in the first 500mm of soil especially at water source.
Termimesh is applicable to all soil types, protected water catchment areas, or high water table aeas.
With the announcement of the Singapore Green Plan 2012, The Ministry of Environment and Water Resource’s (MEWR) intentions is to convert 75% of the land area of Singapore to become Water Catchment Area, the protection of Singapore’s water resources is of paramount importance.
