Amongst the concrete blocks there is an enormous variety of shapes, sizes, colours, and textures now available, with all the major concrete paving manufacturers producing their own versions of the standard rectangular block, and also special shapes, “olde-worlde” looking tumbled or antiqued units, and an ever increasing array of textured blocks.
Concrete Blocks (CBP)
Amongst contractors, specifiers and manufacturers, the blocks are often referred to as “CBP” – Concrete Block Paving
Typical Concrete Block
Most rectangular blocks are moulded to a specific size, 100mm x 200mm x 50-100mm, with exactly 50 blocks per square metre, and, because of this standard size, blocks from different manufacturers may be interchangeable, depending on tolerances and position of any spacer lugs. The typical rectangular blocks tend to have one presentable face, although some blocks are reversible, which makes easy work of replacing stained paving.
Many of the “house brick” manufacturers produce their own ranges of clay paving bricks. These are generally available as typical, rectangular bricks, although there are now a good choice of size variations, from 60x60mm ‘cobbles’, 150x150mm ‘setts’ and 300x300mm squares. Custom shapes can be made for specific projects by some of the more co-operative manufacturers.
The most usual size is 100-105 x 200-215 x 60mm; this means that, with some bricks, there are less than 50 bricks per square metre, and that not all clays are interchangeable. Unlike the concrete blocks, most clays are manufactured with 2 presentable faces, allowing them to be inverted to replace stained paving.
