Cabro blocks also known as paving blocks is a commonly used decorative method of creating a pavement or hardstanding. The main benefit of Cabro blocks over other materials is that individual cabro blocks can later be lifted up and replaced. This allows for remedial work to be carried out under the surface of the cabro block without leaving a lasting mark once the paving bricks have been replaced. Typical areas of use of Cabro blocks would be for driveways, pavement, patios, town centres, pedestrian precincts and more commonly in road surfacing. Cabro blocks are typically made of concrete or clay, though other composite materials are also used. Each has its own means of construction. The biggest difference is the way they set hard ready for use. A clay brick has to be fired in a kiln to bake the brick hard. A concrete cabro block has to be allowed to set. The concrete paving bricks are a porous form of brick formed by mixing small stone hardcore, dyes, cement and sand and other materials in various amounts. Many cabro block manufacturing methods are now allowing the use of recycled materials in the construction of the cabro blocks such as crushed glass and crushed old building rubble.
