At LJP Landscaping we are Reliable & Efficent. We offer a variety of quality driveways which include:
- Block paving
- Paving slabs
There are many types of driveways however we have put together some information regarding a couple of the favourites.
Block paving has been the growth area in the British and Irish Paving Industry over the last 20 years. Mass production techniques have reduced the prices of manufactured blocks to a reasonable level, and made this type of paving affordable to most projects.
Brick or Block paving can be used anywhere. They look great on drives and will provide many years of service. They can be used to great effect as paths, or patios, or mixed with other paving types to create a unique feature. They are a viable alternative to the more traditional asphalt or macadam surfacing for estate roads, and let’s face it, they look a lot better than tarmacadam or plain concrete.
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.
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 (thankfully) 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.
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.
Amongst contractors, specifiers and manufacturers, the blocks are often referred to as “CBP” – Concrete Block Paving. 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.
Coverage rates are very straightforward, as block or brick paving is bought by area. It is wise to allow 5% wastage to allow for cuts and accidents. We ’round-up’ to the nearest full pack of blocks or bricks, to ensure we have plenty. Surplus pavings can sometimes be returned to your supplier for partial rebate (a “re-stocking charge” of 10-20% is common).
There are two laying methods commonly used. The most popular is termed ‘flexible paving’, indicating that the blocks or bricks are laid on a sand bed and the joints filled with a fine silica sand. Rigid paving refers to, usually, clay bricks laid on a concrete or mortar bed with mortar joints, much as a wall, although on the horizontal plane, rather than vertical.
In the picture below we have used a heavy duty landscape fabric, this new driveway was then laid with pink granite stones.
