The problem of construction waste on building sites is not new and continues to be a significant problem to the waste stream. Much has been done to better understand and encourage re-use and recycling, but relatively little has been done on avoiding the occurrence of waste in the first place. A significant contributor to the waste stream on domestic housing sites in Australia is brick waste. A common solution to the problem is recycling the waste into crushed brick, used as a landscaping aggregate or low grade road base. This relies on the stability of recycling markets and so a more ideal situation is to avoid brick waste in the first place. This paper investigates the issue of brick waste and strategies for avoidance. From site investigations, it was found that bricks accounted for the main loose waste onsite (by weight). As much as 75% of this waste was caused from cutting waste often in trying to obtain half bricks. Through experimentation it was found that the brick design could be marginally changed during manufacture to better facilitate a successful `first strike of the brick, providing a clean split and thereby reducing wastage through unsuccessful strikes. This simple change could see a reduction in brick waste on domestic construction sites in Australia
