Block paving is traditionally used for driveways and are many design opportunities due to an
array of colours and types available. There are 3 basic steps to laying block paving; preparing
the site, laying, and jointing, all of which will be addressed in this paving guide.
Preparing the Site
- To ensure longevity and durability, your paving needs to be laid on a solid and even base with sufficient drainage.
- Begin my removing vegetation and topsoil to a depth of 200mm-250mm.
- Mark this area with pegs to the height of the desired surface level of your paving, with a fall of 1:80 to allow for sufficient drainage and 150mm below the damp proof course.
- Rake this area to create an even surface, before compacting with a plate compactor.
- Install edge restraints around this area using block kerbs or concrete edging by bedding them into 100m of concrete at a 45 degree haunch to prevent movement.
- If required, install underground drainage, gratings or manhole covers.
- Next, back-fill the area with 150mm of MoT/crusher run.
- Apply 50mm of slightly damp sand on top and compact with a plate compactor.
- Add a second layer of sharp sand 20mm deep and level it to the required gradient using string lines and screening rails.
- Begin laying concrete block paving from the bottom of a slope, starting at a right angle or straight edge. Work from several packs at a time to ensure an even distribution of colour, especially when using a mixed sixed product.
- Place paving blocks on top of the bedding or laying course in your desired pattern around 4-5mm above the finished level. Make sure the blocks are laid tightly together, in direct contact with adjacent blocks.
- When the full blocks are laid, cut any blocks required for infill pieces or edges using a block splitter.
- Sweep the area and compact the paving using a plate compactor.
- It is advised that you joint the block paving during dry periods.
- Apply a kiln dried sand to the paved area and brush it into the joints, ensuring all spaces are fully filled.
- Use a plate compactor on the paving to push the sand into the joints.
- Fill any missed gaps in the jointing and compact again.
- Be aware that the sand in the joints may need to be topped up for the first few months.
Block paving really can be laid in 3 steps. For a perfectly paved driveway, firstly, prepare the
site so that your paving is laid on a firm, level and well-drained base. Next, tightly lay your
paving in your design before compacting. Finally, joint the paving by brushing sand into the
joints, and voila, your block paving paradise awaits.
