A typical driveway requires a compacted sub-base depth of 100mm to 150mm. This provides the necessary structural support to handle the weight of domestic vehicles without the paving sinking over time.
Versatile Block Paving for Driveways and Patios
The block paving range features concrete blocks in practical sizes such as 200mm x 100mm x 50mm, available in traditional colours including charcoal, heather, and bracken. These blocks are frequently used to lay driveways, garden pathways, and spacious patio areas. Installing a robust foundation is essential for preventing the surface from dipping over time, which involves compacting a layer of Aggregates to create a stable, weight-bearing sub-base before any blocks are set into place.
One of the main practical benefits of this paving style is its versatility, allowing the blocks to be arranged in strong interlocking patterns like herringbone or basketweave. The 50mm thickness meets standard domestic requirements for vehicle traffic, providing a durable surface that withstands daily use. To stop the outer rows from shifting outwards under pressure, finishing the perimeter with Kerbs, Edgings & Risers provides a solid boundary that holds the entire installation firmly together.
Once the paving blocks are laid in their final positions, the small gaps between them need to be completely filled to lock the surface tightly. Brushing a suitable Jointing Compound into these crevices creates necessary friction while also restricting weed growth. Ongoing maintenance is straightforward, and periodically washing the surface with a dedicated Patio Cleaner lifts away accumulated dirt and moss to keep the finished area looking well-maintained throughout the seasons.
Block Paving FAQ's
Paving should never be laid directly onto soil. A proper installation requires excavating the topsoil, laying a compacted aggregate sub-base, and adding a layer of sharp sand to ensure the blocks remain level and stable.
Blocks are usually cut using a manual block splitter or an angle grinder fitted with a diamond blade. This allows for precise cuts that neatly match the boundaries of the installation area.
Sealing is not strictly required, but applying a suitable sealer helps protect the surface from oil stains, reduces colour fading from sunlight, and makes it harder for weeds to take root in the joints.
Kiln-dried sand or a specialised jointing compound is typically brushed over the finished surface to fill the gaps. This locks the blocks together through friction, preventing movement and ensuring the overall stability of the paved area.
