Bushfire Attack Level


A devastating and serious threat in Australia is bushfire. Anyone who lives near dense forest, bush, grassland or the coast should be prepared. A BAL is a classification of the bushfire intensity levels that your house may endure during a bushfire. 

If your property falls within a Bushfire Prone Area (BPA) a BAL can be implemented to assist in selecting building materials for your house and designing the vegetation and gardens around your property effectively to improve the ability of your home to withstand a bushfire attack.  A BAL takes into consideration a number of factors including the slope of land and the presence and proximity of the vegetation surrounding the building.

Rock Solid Earth can help calculate your BAL for you to meet the requirements of the Australian Standard – AS 3959-2009.
