Unlike the Clay Brick Pavers, that can, during the course of baking, slightly warp out of shape, Concrete pavers are created from moulds and have the colour added to them. They are usually more conformed and are easier to lay because of that, Concrete pavers are able to be moulded into Z or S interlocking shapes.
Concrete pavers, which are very easy to lay in a variety of patterns, are also made square and rectangle in many different sizes, the thicknesses vary from approx 38 mm which they call a 40 mm (1 ¾”) paver right up to the Z or S interlocking which can come in 75 mm (3″) thick. Quite often people will choose Concrete Pavers over the Clay Brick Pavers because there is a variety of shapes, Not everyone wants the brick shape and sometimes the large Pavers will suite your landscape theme much better, particularly with the larger entertainment areas.
The Concrete Pavers are often used commercially because of their uniform shape and ease of laying, but are still widely used in the home garden. The Procedures of laying and Points to consider during this work is the same no matter what paver you are laying. These are outlined in the Paver laying procedures.
One of the problems with Concrete Pavers is the colour can fade with time, this is because the actual colour has been added to the mix during the production process, but having said that, the colour can be a little more consistent than the clay brick pavers.
Try to avoid purchasing seconds, these although they are cheap can vary too much in the thickness. this can cause a lot of problems when laying. You prepare your bedding sand and get it all level and your Paver Laying end up uneven, Believe me, Nothing is more frustrating. So stick with the first grade and you won’t go far wrong !!
