How To Core Fill An Existing Block Wall Step By Step Guide. Rules for the use of these elements are contained in Australian Standard 3700-2011īlocks with 390x190mm face = 12.5 units per square metre and 2.5 units per lineal metre. Assuming sound foundations are provided, cracks in walls can be avoided by the correct use of control joints, bond beams and/or joint reinforcement. Clean off droppings as work progresses and before mortar sets.Ĭleaning down with acid should be avoided whenever possible.Ĭare should be taken to order enough product to complete the project at the same time to avoid the possibility of batch variations.Ĭoncrete Masonry’s blocks behave differently to clay brick in regard to moisture movement and temperature changes.
