PATENTS ACT 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT Name and Address of Applicant Actual Inventor(s): Address for Service: Invention Title: P W Saddington and Sons Pty. Ltd., an Australian company, ACN 000 038 531, of 75-77 Lambton Road, Broadmeadow, New South Wales, 2292, Australia David Lees Saddington Spruson Ferguson St Martins Tower Level 31 Market Street Sydney NSW 2000 (CCN 3710000177) Termite resistant mortar and method of termite proofing a structure Associated Provisional Application Details: [33] Country:
AU
[31] Appl'n No(s): 2005904599 [32] Application Date: 24 Aug 2005 The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5845c TERMITE RESISTANT MORTAR AND METHOD OF TERMITE PROOFING A STRUCTURE Field of the Invention The present invention relates to the control of termites, in particular to methods of termite proofing structures and a termite resistant mortar for use in such methods.
Background of the Invention A common method of providing protection for buildings and other ground supported structures against termites is by the use of metallic barriers such as stainless steel mesh or aluminium, or by the use of crushed granite and chemical barriers formed around the exterior of the building.
Use of these barriers creates a need for a further trade on the job requiring specialised installation techniques, this creates further logistical problems on building sites. The chemicals, also, poison the ground and are typically hazardous to humans, animals and vegetation that may come into contact with the chemicals when sprayed about the building site. The effectiveness of the chemicals also deteriorates over time.
Object of the Invention It is an object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages, or at least to provide a useful alternative.
Summary of the Invention The present invention provides a mortar comprising: sand, cement, and one or more additive(s) selected from the group consisting of termite repellents and termite poisons.
Suitable termite repellents include bifenthrin, chlorpuriphos, deltametherin, boron and chilli extract.
Suitable termite poisons include imidacloprid, fiprinol and arsenic trioxide.
The mortar may further comprise a plasticising agent, such as an air detrainer and/or air entrainer, to enhance the workability of the mortar as desired.
The mortar may also further comprise an expanding agent to offset shrinkage of the mortar during setting of the mortar. The mortar may still further comprise a retarding agent to retard setting of the mortar. Various known polymeric additives may be used as plasticising and/or regarding agents.
[R:\LIBLL1775812 Specification.doc:prw 2 There is further disclosed herein a method of termite proofing a masonry structure laid on a foundation, said method comprising laying at least a lowermost course of masonry elements, forming at least part of the exterior periphery of said structure, on said foundation with a mortar as defined above interposed between adjacent masonry elements and between said lowermost course of masonry elements and said foundation.
Typically, said foundation is a concrete slab.
Typically, said mortar extends to at least 75 mm above ground level.
In the context of this specification, the term masonry element includes clay bricks, stone blocks, calcium silicate blocks and concrete blocks.
Brief Description of the Drawings A preferred form of the present invention will now be described by way of example with reference to the accompanying drawing, wherein: Figure 1 is a front elevation view of part of a wall of a building.
Detailed Description of the Preferred Embodiments Referring to Figure 1, a masonry structure in the form of a building 1 is laid on a foundation in the form of a concrete slab 3 formed adjacent to ground level 4. A masonry wall 2 forms part of the exterior periphery of the building 1. The masonry elements 5 of the wall 2 are laid in the usual manner, with the lowermost course of masonry elements being laid on the concrete slab 3, and successive courses of masonry elements 5 being laid on top of each other. The masonry elements may be of any suitable form and construction, including clay bricks, stone blocks, calcium silicate blocks or concrete blocks.
Standard brick mortar, which is typically used when laying such a masonry wall, typically consists of a mixture of six parts of sand, one part cement (generally Portand cement) and one part lime by volume. These volumes are generally measured roughly on site. The lowermost course of masonry elements 5 is typically laid on a bed of such mortar interposed between the concrete slab 3 and the lowermost course of masonry elements 5, with a further layer of mortar interposed between both horizontally and vertically adjacent masonry elements 5. Such mortar is, however, susceptible to intrusion by tennites, which remove the sand and eventually penetrate the mortar, allowing access to the interior of the building 1 through the gaps between adjacent masonry elements As a result of the susceptibility of standard brick mortar to termite intrusion, the above described mechanical and chemical methods of protecting buildings against termites are used almost exclusively.
[R:\LIBLL]775812 Specification.doc:pvrw 3 In a preferred embodiment of the present invention, a termite resistant mortar 6, including either a termite poison or termite repellent, is used in place of a standard brick mortar when laying at least the lowermost course of masonry elements 5. Accordingly, a layer of the termite resistant mortar 6 is interposed between adjacent masonry elements and between the lowermost course of masonry elements 5 and the concrete slab foundation 3. The termite resistant mortar 6 would typically be used in the lowermost courses of masonry elements 5 up to at least 75 mm above ground level 4. On a sloping building site it will be typical to lay the masonry elements with the termite resistant mortar 6 in as many brick courses 5 as is necessary until the termite resistant mortar 6 is lo at least 75 mm above ground level 4.
With the inclusion of a termite poison as an additive in the mortar, the termite attacking the mortar, seeking to break down the mortar by extracting individual sand particles in the usual manner, will be poisoned by the termite poison that would be otherwise locked within the set mortar. If the termites were somehow smart enough to not attack the mortar, or to stop their attack on the mortar after contacting only a small amount of the poison, they would be forced to climb up the wall 2 beyond the termite resistant mortar to seek a passage into the building 1. Given the aversion of termites to light, the termites will typically build dirt tunnels from ground level up the wall for protection as they climb. Such tunnels are readily visually identifiable and thus provide an early warming of termite activity through visual inspection.
Suitable termite positions for inclusion as additives in the mortar include imidacloprid, fiprinol and arsenic trioxide.
Similarly, when a termite repellent is included as an additive in the mortar, the termites will be repelled from the mortar either when they come into the vicinity of the mortar, if the repellent remains active on the surface of the mortar, or at least once the termite begins attacking the mortar, effectively unlocking any termite repellent locked within the mortar. Again, if the termites are smart enough to avoid the mortar and climb further up the wall 2 beyond the termite resistant mortar to seek a passage into the building, tunnels built by the termite will be readily visually identifiable.
Suitable termite repellents that can be used as additives in the mortar include chlorpuriphos, boron and chilli extract.
Whilst the termite resistant mortar 6 might be utilised for laying masonry elements throughout the entire height of the wall 2, the typically increased cost of a termite resistant mortar compared to a standard mortar may dictate that the termite resistant [R:\LIBLL]775812 Specification.doc:prw 4 IDmortar is only utilised in the lowermost courses of masonry elements to at least above ground level, with a standard mortar 7 being used in the upper courses.
The mortar should be prepared in accordance with the requirements of Australian ;Standard AS 3700 2001 (Masonry Structures), the entire disclosure of which is incorporated by cross-reference. Other additives in addition to termite poisons or repellents may be used as desired. Such further additives may include plasticising agents (such as air detrainers and/or air entrainers) to enhance the workability of the mortar, t expanding agents to offset shrinkage of the mortar during setting and retarding agents to retard setting of the mortar. If the additive(s) is/are provided in powder form, water will be added to the mortar when preparing the mortar for use in the usual manner.
The mortar may also be provided with some form of visual identifier, such as a coloured additive, which will assist in visual inspection of the wall 2 to confirm that the termite resistant mortar 6 has been utilised correctly in place of a standard mortar.
