Paving

There two basic types of block paving; the moulded concrete block (CBP - Concrete Block Pavers), and the kiln-fired clay brick, hence the interchangeability of the terms block and brick paving. In the following notes, concrete types are referred to as blocks, and clays as bricks. However, both may also be known as pavers, paviors, or paviours, as well as some more obscure terms.

Concrete block paving, the bricks and blocks are available in a range of thicknesses, from 40mm to 100mm. There are even 120mm units for exceptional applications, but they are not likely to be found in stock at your local supplier! For domestic use, the 50mm or 60mm units are most suitable. 80mm thick units are used for road construction or where there will be regular vehicle overrun, while the 100mm thick units are for heavy-duty pavements such as those in Freight Yards, Ports and Airports. We find that the 40mm thick blocks are now difficult to obtain and offer no significant cost saving over a 50mm thick unit. They are/were also particularly prone to breakage during the compaction phase of construction.

Given the wide range of products on the market, choosing a block or brick paver for any given project can be a long, complex and fraught decision.
