Screeding a bedding layer | Pavingexpert

This is our preferred method, the one we have found to give fewest problems with settlement, and the easiest to undertake on site. The laying course material is spread in one layer, lightly compacted with only one or (at most) two passes of the vibrating plate, then screeded to a level that allows for final compaction of the paving units down to finished level.

Concrete Movement Joints | Pavingexpert

Movement joints are also useful when laying concrete within an area bounded by walls or buildings, or when an object such as a manhole cover has to be incorporated within the slab, as they allow the concrete to expand and/or contract without transferring pressure onto the other structures, causing cracks within the concrete slab, or the wall, MH cover, etc.

Cutting porcelain and ceramic paving | Pavingexpert

Bench saw for cutting porcelain paving . Hand-held cut-off saws have a gyroscopic effect due to the high-speed spinning of that large blade, and while this tends to 'steady' the saw when in use, it can make it extremely difficult to keep the cut perfectly straight, as even the slightest twitch or tic or tremor is exaggerated by that same gyroscopic effect.
