The use of blockwork allows structures to be built in the traditional masonry style with layers (or courses) of staggered blocks.Ĭoncrete blocks may be produced with hollow centers (cores) to reduce weight, improve insulation and provide an interconnected void into which concrete can be poured to solidify the entire wall after it is built.ĬMUs are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them. These rods can run both horizontally and vertically and would be fastened at each side and/or top and bottom.A building constructed with concrete masonry blocksĪ concrete masonry unit ( CMU, also known as a cinder block, breeze block or by various other terms) is a standard-size rectangular block used in building construction. This system uses to good effect the rebates provided in the edges of the blocks that house the structural steel rods that can run through the mortar joints. See the pictures below demonstrating this system. Naturally every job is different and specific advice should be received for every project. This housing of the structural steel rods that run through the mortar joint in every second course effectively ties the block assembly to the vertical posts. These tabs have a large holes which provide a void for structural steel rods to run through every second course or 600 mm.
This can be done with either brick ties spot welded to the columns and inserted in the block work joints or steel tabs fixed at intervals of 600 mm protruding into the vertical joints. This is a system where the wall is supported by vertical steel columns sitting behind the block wall at suitable frequencies that have strategically located tabs that tie the block work wall to the columns. This also prevents situations where a customer in Perth might run one block short of finishing a job.įor more discreet structural outcomes we have developed a design to provide a sound structural framework for larger installations that minimises the visual impact of the structure. We have very few breakages but do recommend a small allowance for damages to ensure you have the right number of blocks for the job. Generally we wait one week before shipping blocks to allow them to achieve the necessary level of strength. All our products are extruded under pressure and air dried for two days before packaging to allow further drying. It is important to have the right advice when contemplating putting together a composition of any of our products to understand the structural requirements to ensure the installation is first and foremost safe. Once the necessary level of comfort is achieved through consultation with your bricklayer and/or engineer depending on the size and nature of your project, you then need to ensure the built outcome matches the design requirements specified/agreed.Īll our blocks are made with a special sand mix combined with aggregate, cement and water to allow our production process that works primarily on vibration and compaction. Due to the composition of most our our blocks they are not suitable carrying structural loads. All our products are well suited for external and internal applications as non structural elements. These products are developed as architectural features that create an aesthetic differentiation coupled with a practical outcome providing privacy screening and thermal shading. Most of our standard breeze block products come in a 290 mm x 290 mm x 90 mm format.
