Abstract: The present invention relates to a method for protecting the lower regions of and structure of a building (10) from damage or degradation by termites. The method comprises the steps of creating a region in the ground below the building having properties hostile to termites whereby to discourage them from approaching the vicinity of the building. In one embodiment means for creating a hostile region in the ground below the building are provided by a pump (12) which creates a superatmoshpheric pressure field (40) in this region. Treatment agents (31) such as ozone may be delivered to the ground region in order to provide a hostile effect to the termites by affecting their pheromone chemistry and/or their reproductive or communicative behavior. A secondary function of the present invention relates to the creation of a forced ventilation (46) of the habitable region (18) within which the apparatus of the present invention resides.

Abstract: There is provided an apparatus (1) and method for protecting a building (3) from pests or other nuisances in the vicinity of buildings. The apparatus (1) comprises a monitor (7) having the ability to acquire environmental condition information relating to environmental conditions in a vicinity of the building (3), and a treatment controller (9) which is capable of using the environmental condition information received from the monitor (7) to provide an amount of treatment agent which, for those environmental conditions, remains below a safety threshold for habitation of the building (3) and reduces a population of the pests. The present invention circumvents the need to evacuate inhabitants of the buildings before any treatment agent is administered to the ground lying therebeneath. Further, near-continuous protection and treatment of buildings is also possible.

Abstract: The present invention relates to apparatus for protecting the lower regions of and structure of a building (10) from damage or degradation by a target subterranean degradation factor (42) such as a termite or fungus, for example. The apparatus comprising means (12) for creating a region in the ground below the building having properties hostile to the target subterranean degradation factor whereby to discourage the degradation factor from approaching, or growing within the vicinity of, the building. In one embodiment the means for creating a hostile region in the ground below the building are provided by a pump (12) which creates a superatmospheric pressure field (40) in this region.

Abstract: A system for use in preventing a flow of gas from a gas-containing region (20) to an adjacent region (22) and/or for collecting or dispersing gas at the interface between the regions, comprising a composite barrier (10) installed so as to separate the two regions (20, 22), the barrier (10) comprising a gas-impermeable layer (11) and a gas-permeable membrane (12) interconnected so as to define an interspace (16) between them and arranged with the permeable layer (12) facing the region containing gas (20) to be dispersed or collected. A method is also described comprising the steps of connecting an aperture (36) or aperture of the barrier communicating with the interspace (16) thereof to pumping means (37) which, in operation, act to pump gas into or out from the interspace (16) by creating a pressure differential across the permeable membrane such as to cause gas to flow therethrough across a major proportion of its surface area.
