Before we explain what masonry anchors are, we must first define masonry itself. In its simplest form, masonry can be described as anything that a mason puts down. In other words, if it is laid by a stonemason or a bricklayer, then it is masonry. This can include building materials such as stone and brick, as well as block walls.
Blockwork walls are made from blocks that are commonly known as breeze block, Thermalite block, concrete blocks, or cinder block. Blocks are typically much quicker to lay than brick, so they are often used for the interior walls of modern houses. The walls are then covered with plaster or plasterboard to provide a smooth finish.
