There are six main categories of GREENZONE® application across the residential, commercial and industrial building sectors:
- Service penetration
Service penetrations – such as plumbing, which goes in before everything else – penetrate through concrete slabs and have the potential to provide concealed access for Termites to enter.
GREENZONE® is used as an expansion foam around pipe penetration and by using GREENZONE® this way the need to install a secondary termite collar barrier is removed.
- Expansion and contraction joints
An expansion joint or movement joint is an assembly designed to safely absorb the heat-induced expansion and contraction of construction materials, to absorb vibration, to hold parts together, or to allow movement due to ground settlement or potential earthquake.
Expansion joint foam is essential in any kind of concrete construction as it allows the slab to expand and contract without cracking and protects other building elements such as plumbing during the slab pour process. These joints are the precise areas that require protection from termite incursion.
- Concrete precast panels
Precast concrete is a construction product produced by casting concrete in a reusable mold or ‘form’ which is then cured in a controlled environment, transported to the construction site and lifted into place. In contrast, standard concrete is poured into site-specific forms and cured on site.
When concrete paving abuts concrete wall panels (internally and externally) there is a need for expansion foam in the control joints. Used in this way GREENZONE® provides both termite protection and addresses the expansion/contraction of concrete paving in one step.
- Brick veneer (perimeter wall/path joint)
GREENZONE® is used as an expansion joint foam where concrete paving sits next to an exterior brick wall. By using GREENZONE® this way, there is no need to install any kind of other termite fabric barrier.
- Concrete stump and timber sub-structure
The location of stumps or piers are normally marked out using spray paint. Holes are then dug at these specific locations using an auger. GREENZONE is used as a termite separation barrier between the concrete stump and timber substructure – a common entry point for termites.
- Doors and windows
As well as being an effective termite repellent GREENZONE® is also a proven repellent barrier against ants and cockroaches. When applied on doors and windows of homes and high rise building the results are excellent.
In summary, buildings can be effectively protected from subterranean termite attack and GREENZONE offers the best possible chance of long lasting protection of your greatest asset.
The level of protection provided and the associated risk will vary depending upon construction type, preventative measures taken and the level of regular inspection and maintenance.
