Pallet of 108 blocks. Baines Masonry's Betta Blocks, often known as Besser blocks or Bessa blocks, are lightweight, but strong. Despite a dry weight of less than 10.5kg, Betta blocks still have a compressive strength of more than 15 Mpa. The blocks also comply with Australian Standards AS4456.4 Transport Advantages, with the lighter weight meaning more blocks per load, reduced diesel usage and more convenience for you. Betta blocks have excellent environmental credentials with a carbon footprint that is 45% lower than standard masonry and other 'light weight' options. This is achieved by using 65% heavy industry by-products, reducing the amount of landfill coming from coal fired power stations and the steel making industry, and half the amount of cement normally required (cement production produces a tonne of carbon for each tonne of cement).
