Building Resilience Knowledge Database

The Building Resilience Knowledge Database (BRKD) is a portal of information on the resilience of building products and materials to extreme weather events.

The BRKD provides a repository of reliable information and presents the information in a format this is easy to understand. Where no information about resilience of building materials exists the BRKD encourages building product suppliers and experts to help fill the gaps.

How to find the information you are looking for

The BRKD is broken down by ‘hazards’ and ‘building products’. You can find the same information through a number of different pathways:

  • type a word in the search bar at the top of this page
  • select a hazard or a sub-hazard to get more information on the resilience of materials to these hazards
  • select the part of the building or the building material for which you would like more information
  • follow the 'read more' links below to explore the information on the website

The BRKD is funded by the Insurance Council of Australia.

Inundation

Inundation is the covering of something by water. Higher than usual water levels may be caused by a number of factors including excessive rainfall, storm surge, or dam break that overtop the natural or artificial banks of a stream, creek, river, estuary, lake or dam.

Storm

Thousands of storms occur every year in Australia but only some of these are severe enough to cause serious damage. Storms are ‘atmospheric disturbances’ that can include strong winds, hail, heavy rain and lightning.

Inundation - Freshwater

According to the Bureau of Meteorology the most common reason for inundation to occur in areas where it is an issue is the flooding of rivers. Drainage systems in urban areas are subject to similar problems.

Ground Floor

The ground floor of a building is the supporting structure for the floor and walls at the first usable level of the building. For most houses this will be at the same level as the site surrounding the house, these are referred to as ‘slab on ground’.  Some houses, such as ‘Queenslanders’, may be raised above the level of the surrounding site, these are referred to as ‘suspended’ ground floors.

Hail

Hailstones form in the cold tops of thunderstorm clouds and fall to earth when they move outside the wind flows within a storm cloud or when they become too large to be supported by the air movements in the cloud. Large hail stones are defined as those that are bigger than 2cm in diameter.

Wind & Rain

Strong wind and rain is a unique category because when these two hazards combine they may have different effects to when they are on their own. For example, when rain is driven by strong winds it can fall at an angle and may get under building components such as roof tiles, which can in turn cause problems in the roofing area.

What is the difference between this rating and supplier ratings?

The rating you see at the top of the page is the resilience rating of the generic class of building material to a particular hazard. A supplier rating is particular to a specific supplier product. For example, clay bricks may have a resilience rating of '3' to inundation but a supplier may have made specific improvements to their bricks and may be able to achieve a resilience rating of '5' for their clay brick.
