Block paving
Block paving comes in many different shapes, colours and sizes with the most popular being Driveline and Tegular with options of 50 or 80mm depths. 50mm is often used for pedestrian walkways and 80mm for vehicles and heavy traffic. Once foundations are appropriate and compacted, sand or other equivalent products can then be screened to correct heights and falls. String lines are then usually set up to make sure the blocks are in continuous straight lines throughout the works.
When setting up for block paving projects you should always try to make sure you are square off the adjacent building or square off the sufficient equivalent, you can do this by using a set square and string lines and by taking precise measurements of the subject structure. Block paves are then laid manually in uniform patterns before being covered with dry sand to fill in the joints between blocks and then compacted using a compactor.
