Also known as Block layers, Block masons use the same methods as a brick mason. Block masons may strike the joints on both sides for both sides of the block wall may show. If the structure gets a coat of stucco, sheetrock or a different type of masonry. The mason may cut the mortar joint rather than just leave mortar weeping through. Blocks masons will usually fill the cells with rebar, grout and or insulation material. There are many other materials a block mason may install. Mortar belts, mortar net, rebar positioners, truss and ladder wires are most common. Usually, a Block mason will build the corner leads first then fill in between those leads a few feet in height at a time. The block mason will need discipline in keeping the leads square, level and plumb while maintaining correct height and length.
The R-value, sound barrier along with strength are a few reasons why blocks are a great building unit. Where backup walls are needed a wall made of blocks can provide more cost effective and quicker installations. For more r-value and strength filling the block cells with grout will create even higher ratings. Insulation such as vermiculite mineral are also used in the block cells. Reinforcements such as rebar can also be installed within the block cells for twice the strength.
Blocks are known as cinder blocks, concrete masonry units and or CMU’s for short. It is very common to see concrete blocks in commercial and industrial buildings. Blocks are rare in residential homes but are used for framing the walls. Blocks are used in chimneys, firewalls, foundations, partitions and even used for framing buildings and homes. For a one-step system, install blocks come in many shapes and colors such as smooth face and split-faced along with many others characteristics.
Concrete blocks are made of portland and aggregate and have hollow cells for rebar and grout. also, choose to use either a lightweight or normal weight. Concrete blocks are commonly misinterpreted as light or heavyweight blocks. The truth is Cinder blocks are different and made of dusty remnants of burned coal called cinders thus giving the name cinder. Now that you have an idea what blocks and cinder blocks are and what they are for maybe your needing a block mason for your project.
We have built firewalls, retaining walls, buildings, garages, foundations, chimneys, and fireplaces, Infills, cut outs and also split faced and custom blocks on many projects. Most neighborhood walls and entries are made of block. To have an aesthetic look most walls are built with one side block and the other side with a brick, stucco or stone exterior. Privacy fence on occasions is made of concrete blocks giving a more sound barrier from loud vehicles or noisy neighbors. Free standing brick and stone columns would need a block frame for support.
