❂ 

在设计阶段

如果您正在建造新的住宅或扩建,您可以选择使用抗白蚁的建筑结构,如混凝土板,防白蚁木材和钢框架。

这样做,您可以将白蚁损害的可能性限制在更易于检测和更换更便宜的次生和浅表元素上。

这做法可以减少未来的持续成本,并使用传统材料和施工方法,不依赖于定期维护系统或专业责任政策。

或者,您可以在施工期间指定安装的物理或化学屏障。这符合澳大利亚标准(AS3660.1),并应在设计阶段完成。

一些屏障将需要持续的检查,维护和化学品补给。

在建筑施工

如果尽量去除树桩,根部,下部切割部分并恰当地巩固土壤以最大限度地减少混凝土板的裂缝,就可以减少白蚁攻击的风险。

如果在预备的地面上正确设计和建造混凝土,它是一个非常有效的白蚁屏障。

白蚁可以吃除木材以外的任何纤维素材料,甚至包括电缆,塑料和其他复合建筑材料。虽然这不包括混凝土,但小至1.5mm的裂缝也可能会让白蚁进入墙壁和地板下方的空腔。

买房子时

强烈建议您在购买房屋之前,请专家检查其是否适合白蚁活动。

完整报告的成本与维修的潜在费用相抵。

确保您聘请合格的,经验丰富的保险害虫检查员,并要求他们报告可安装的任何白蚁管理系统的类型,年龄和状况以及用于关键结构元素的材料。

长期管理

通过应用化学或物理屏障(或两者)来防止白蚁侵入结构,可以获得长期管理。澳大利亚标准(AS3660.1)已经写在这个主题上。

目的是使任何纤维素材料,特别是木材远离土壤接触,并鼓励在开放的地方建造泥管,并进行定期仔细检查。白蚁管理系统的设计目的是阻截隐蔽的入口,并迫使白蚁进入开阔的地方,在泥土隧道可以更容易地被发现。

物理障碍包括小粒级石材颗粒,不锈钢丝网和化学浸渍复合材料产品。白蚁抗性材料的设计是为了保护您家的重要隐蔽结构元素,同时确保任何白蚁活动的小目标

确保您使用的产品已通过认证并符合澳大利亚标准,最重要的是,您必须安排适当的合格操作人员进行定期检查。

还应该充分了解正在进行的维护要求和最佳的施工前或施工后选项。

❂ 部分英文原文

At design stage

If you are building a new home or major extension, you can choose to use termite resistant primary structures like concrete slabs, termite resistant timber and steel frames.

By doing this you limit the potential for termite damage to secondary and superficial elements which are easier to detect and cheaper to replace.

This option may reduce future ongoing costs anduses conventional materials and construction methods and does not rely on aregular maintenance system or professional liability policy.

Alternatively you can specify a physical orchemical barrier to be installed during construction. This should be inaccordance with the Australian Standard (AS3660.1) and should be finalisedduring the designs stage.

Some barriers will require ongoing inspections,maintenance and/or chemical replenishment.

During building construction

The risk of attack can be reduced if effort ismade to remove tree stumps, roots, off-cuts and to properly consolidate thesoil to minimise cracks in concrete slabs.

Concrete is a very effective termite barrier ifit is correctly designed and constructed on properly prepared ground.

Termites eat any cellulose material whichbesides wood, can even include electrical cabling, plastics and other compositebuilding materials. While this does not include concrete, cracks as small as1.5mm may allow termites to find their way into a cavity such as walls andbeneath floors.

When buying a house

It is strongly recommended that before you buya house, you have an expert inspect it for termite activity.

The cost of a full report pales against thepotential expense of repairs.

Ensure you engage a properly qualified,experienced and insured pest inspector and ask them to report on the type, ageand condition of any termite management system which may be installed, and onthe materials used for critical structural elements.

Long-term management

Long-term management can be gained through theapplication of chemical or physical barriers (or both) to prevent termites frompenetrating the structure. An Australian Standard (AS3660.1) has been writtenon the subject.

The aim is to keep any cellulose material,especially timber, away from soil contact and to encourage termites to build amud tube out in the open where it can be seen during a regular, carefulinspection. Termite management systems are designed to stop concealed accessand force termites into the open where their mud tunnels can be more easilydetected.

Physical barriers range from small graded stoneparticles, stainless steel mesh and chemically impregnated composite products.Termite resistant materials are designed to protect the critical concealedstructural elements of your home, while ensuring a 'small target' for anytermite activity.

Ensure you use a product that has beencertified and complies with the Australian Standard and, most importantly, youmust arrange for appropriately qualified operators to carry out regularinspections.

You should also be fully informed about ongoingmaintenance requirements and the best pre- or post-construction options.
