Block Paving Guide | What Does it Cost? | How Much Per m2?

October 25, 2023

Block paving is a versatile and durable option for creating driveways, patios, and paths. This method involves using individual concrete or clay blocks called pavers, which offer both functional benefits and aesthetic appeal. In this comprehensive guide, we’ll explore the different types of block and paver options, construction methods, selecting the right blocks, and popular paving patterns. Whether you're planning a new driveway or refreshing your patio, this guide will provide the insights needed to make informed decisions about your block paving project.

Block paving has grown increasingly popular in the UK and Ireland over the past 40 years, thanks to advances in manufacturing that have made blocks more affordable. Today, blocks cost only slightly more than plain flagstones, making them a cost-effective choice for driveways and other paving projects. Their versatility means they can be used for everything from garden paths to heavy-duty areas like docks and freight yards.

Key Block Paving Benefits:

Affordable compared to other paving options
Attractive and allows for creative designs
Durable and long-lasting
Suitable for various applications, including driveways and patios
Customizable in size, shape, and color

Concrete Blocks

Concrete blocks, also known as CBPs (Concrete Block Pavers), are available in a range of thicknesses from 40mm up to 100mm. For residential use, 50mm or 60mm thick blocks are most common, while 80mm blocks are used for roads or areas with regular vehicle traffic. The standard shape is rectangular, but other shapes are also produced. A typical size is 100mm x 200mm, providing coverage of around 50 blocks per square meter. Color is added using concrete dyes during manufacturing, though fading can occur over time.

Clay Pavers

Clay pavers are made from natural clay and fired in high-heat kilns. Typically sized around 100mm x 200mm, these pavers showcase the natural colors of the clay, providing a wide range of hues with minimal fading. Clay pavers are generally harder to cut than concrete, but they provide excellent traction when wet. However, they can promote moss and algae growth more than concrete pavers.

Both concrete and clay offer high-quality paving solutions, each with its own advantages. Choosing the right material depends on factors like cost, aesthetics, and the specific requirements of your project.

Block Paving Patterns

Choosing the right pattern for your block paving is crucial for both aesthetics and functionality. Patterns not only define the look of your space but also affect the stability and longevity of the installation.

Stretcher Bond Pattern

Stretcher and stack bonds create patterns by laying bricks in repeating rows. The stretcher bond offsets rows by half a brick length, creating a "running bond" that allows for close brick alignment. Stack bonds align bricks vertically for very uniform lines. While these patterns are simple, they may shift over time without sufficient edging, making them best suited for patios.

Herringbone Patterns

Herringbone patterns are a popular choice for driveways due to their interlocking nature, which provides unmatched stability. A 90-degree herringbone pattern is the easiest to lay, with bricks placed perpendicular to edges. A 45-degree herringbone pattern requires meticulous measuring for precise angles but creates a more dramatic zigzag effect.

90-Degree Herringbone Pattern

The 90-degree herringbone pattern is a classic style that uses right angles. In this pattern, the rectangular pavers are placed in an interlocking arrangement with each paver oriented perpendicular (at 90 degrees) to the pavers in adjacent rows. This creates a distinctive zigzag effect, providing both visual appeal and structural stability. This pattern is ideal for driveways and paths where a stable, interlocking paver configuration is required.

45-Degree Herringbone Pattern

The 45-degree herringbone pattern offers a sharper, more dynamic zigzag effect compared to the 90-degree pattern. However, the angled positioning requires precise measuring and spacing to achieve accurate joints throughout. This pattern is ideal for those seeking a visually striking design with enhanced stability.

Creative Patterns

For those looking to add a unique touch, creative patterns like basketweave can provide an eye-catching design through alternating vertical and horizontal brick placement. Varying the color between bricks can further enhance the visual appeal. However, without proper edging, these creative patterns may shift over time, making them better suited for patios than high-traffic areas.

Choosing Block Paving Patterns

The optimal block paving pattern depends on the intended use, desired aesthetic, and need for stability. Contemporary stack bond or classic herringbone patterns suit most driveway applications, while more creative basketweave and color variations are better reserved for patios. Consulting a knowledgeable paving contractor can help ensure you select the best block paving pattern for your specific project.

How Many Block Paving Slabs per m2?

The standard size for most rectangular concrete block pavers is 100mm x 200mm. When laid with tight joints, this block size means on average, there are 50 blocks per m2. This consistent coverage rate simplifies planning and purchasing for any block paving project, ensuring easy calculation of the quantities needed based on the total paved surface area.

How Much Does Block Paving Cost?

The average cost for block paving ranges between £80-£120 per m2, including all labor and materials. Basic concrete blocks are on the lower end, while specialized blocks and clay pavers are more expensive. The total cost depends on the size of the area, design complexity, and the preparation work needed.

For example, a small single-car driveway (11.5m2) might cost between £920-£1,380, while a larger two-car drive (25m2) could range from £2,000-£3,000. Average driveways (50m2) typically cost £4,000-£6,000, with large driveways (100m2) ranging from £8,000-£12,000. These figures are approximate guides; for accurate pricing, obtain quotes from contractors.

In summary, block paving is a flexible, durable, and visually appealing option for various outdoor projects. With the right choice of materials and patterns, you can create stunning driveways, patios, and paths that will last for years to come.
